BREAKING NEWS ITEMS [2005]
December 23, 2005; Tokyo, JAPAN (WSJ, p. A1) - Japan's Ministry of Health said that "the long-predicted decline in population has started." It reported the number of 2005 deaths will exceed births.
December 9, 2005; Atlanta, GA (AP) - According to the latest data from the National Center for Health Statistics, U.S. life expectancy has hit another record high -- of 77.6 years, while deaths due to heart disease, cancer, and stroke continue to drop. Still, there is a worrisome turn: Half of Americans in the [55 - 64] cohort - including the oldest of the so called "baby boomers" -- - have high blood pressure, and two in five are considered obese. That means that they are in worse shape in some respects than Americans born a decade earlier were, when they were the same age.
The health of this large group of the near-elderly is of major concern to American taxpayers because they are soon becoming eligible for Medicare and Social Security. "What happens to this group is very important because it's going to affect every other cohort below them," said Amy Bernstein a co-author of the latest government report. The [55 - 64] age group is expected to rise from 29 million Americans in 2004 to 40 million in 2014.
December 8, 2005; Sra. Maria Esther Capovilla, born September 14, 1889, has recently been confirmed by The Guinness Book of World Records to be 116 years old. Click on her photo for more details.
November 24, 2005; Prof. Hwang Woo Suk of Seoul National University, the first scientist to
clone a dog [See our story of Snuppy dated August 3rd below], has now confessed to
lying to the media (with mitigating circumstances having to do with patient privacy and not as a
result of suspected coercion of two female lab workers). He has subsequently resigned his South
Korean Government post, presumably as a form of atonement for his role. Click on the photo for
more details. This saga is further continued in the news
item for January 10, 2006.

September 24, 2005; The California Science Center in Los Angeles has launched a new speakers program entitled Science Matters with the aim of exploring challenging current science issues at the forefront of public concern. The first meeting, Introduced by former- California Gov. George Deukmejian, was held today on the topic of Stem-Cell Research . There was an audience of nearly 900 attendees on a Saturday afternoon! Click on the photo for more details about the panel.
September 9, 2005; California's stem-cell-research agency awarded the first of a planned $3 billion in grants today to help organize programs to train scientists. CIRM announced that a little less than $39 million would be awarded to the following institutions: UCLA, UC Irvine, UC San Francisco, UC San Diego, UC Santa Cruz, UC Berkeley, UC Davis, the La Jolla-based Burnham Institute for Cancer Research, Childrens Hospital Los Angeles; the Scripps Research Institute in La Jolla; the J. Gladstone Institutes, affiliated with UC San Francisco; the Salk Institute for Biological Studies in La Jolla, Stanford University, the California Institute of Technology, and the University of Southern California.
Not everyone was happy with this announcement however. Mr. Jesse Reynolds, a Program Director on Biotechnology Accountability of the Center for Genetics and Society, located in the San Francisco Bay Area, said "CIRM should have delayed all funding decisions until the legal issues were resolved. It's irresponsible for anyone to promise something you're not sure you can deliver."

September 8, 2005; What exactly makes a stem cell a stem cell? The question may seem circular, but while we know a great deal of what stem cells can do, we still don't understand the molecular processes that afford them such unique plasticity. Now, researchers at Whitehead Institute for Biomedical Research working with human embryonic stem cells have uncovered the process responsible for the single-most tantalizing characteristic of these cells: their ability to differentiate into any type of cell in the body (~220 varieties along three major tissue types), a trait known as pluripotency.
"This is precisely what makes these stem cells so interesting from a therapeutic perspective," says Whitehead Member Richard Young, senior author on the paper which will be published September 8th in the early on-line edition of the journal Cell. "They are wired so they can become almost any part of the body. We've uncovered a key part of the wiring diagram for these cells and can now see how this is accomplished."
Once an embryo is a few days old, the stem cells start to differentiate into particular tissue types, and pluripotency is forever lost. But if stem cells are extracted, researches can keep them in this pluripotent state indefinitely, preserving them as a kind of cellular blank slate. The therapeutic goal then is to take these blank slates and coax them into, say, liver or brain tissue. But in order to guide them out of pluripotency with efficiency, we need to know what keeps them there to begin with.
Researchers in the Whitehead Laboratories of Young, Rudolf Jaenisch, MIT-computer scientist David Gifford, and the Harvard Lab of Douglas Melton focused on three proteins known to be essential for stem cells. These proteins, Oct4, Sox2, and Nanog, are called transcription factors or chemokines, proteins whose job is to regulate gene expression. (Transcription factors are really the genome's primary movers, overseeing, coordinating, and controlling all gene activity.)
These proteins were known to play essential roles in maintaining stem cell identity - if they are disabled, the stem cell immediately begins to differentiate and is thus no longer a stem cell. "But we did not know how these proteins instructed stem cells to be pluripotent," says Laurie Boyer, first author on the paper and a postdoctoral scientist who divides her time between the Jaenisch and Young Labs.
Using a microarray technology invented in the Young lab, Boyer and her colleagues analyzed the entire genome of a human embryonic stem cell and identified the genes regulated by these three transcription factors. The research team discovered that while these transcription factors activate certain genes essential for cell growth, they also repress a key set of genes needed for an embryo to develop.
This key set of repressed genes produce additional transcription factors that are responsible for activating entire networks of genes necessary for generating many different specialized cells and tissues. Thus, Oct4, Sox2, and Nanog are master regulators, silencing genes that are waiting to create the next generation of cells. When Oct4, Sox2, and Nanog are inactivated as the embryo begins to develop, these networks then come to life, and the stem cell ceases to be a stem cell.
The new work provides the first wiring diagram of human embryonic stem-cell regulatory circuitry. "This gives us a framework to further understand how human development is regulated," says Boyer.
"These findings provide the foundation for learning how to modify the circuitry of
embryonic
stem cells to repair damaged or diseased cells or to make cells for regenerative medicine," says
Young. "They also establish the foundation for solving circuitry for all human cells."

[ Editorial Comments: In our view, this is one of the most important papers of the past two months. One of our GRG members, Mr. Robert Bradbury of Seattle, WA asks, "Obviously, the $64,000 question is "What happens if you turn all or some of these genes back on?" "For example, does one then get de-differentiation?" Of these three factors, it appears that Nanog is more fundamental, but it is clear that we need to understand the complete set of chemokine commands (some of which may actually be located in oocyte cytoplasm and become active for the first time following fertilization by a sperm to demethylate nucleotides and deactylate histones along the DNA, so that permanently switched-off genes can be reactivated.) if we are to form "legal sentences" in the Embryonic Stem-Cell Command Language, commands that turn off, as well as turn on, processes of development, lest we recapitulate the cautionary tale of the Sorcerer's Apprentice , where we have to wait for the "Sorcerer" to come home before the "Apprentice" can stop flooding the house with buckets of water simply because he hastily experimented with his incomplete knowledge without having read and understood the entire "Book of Magic" about how to "reboot" the system. During embryogenesis, timing is everything, and we may have to explore thousands of non-coding microRNA molecules (RNAi) that serve as commands for the exquisite temporal monotonic (irreversible) control of gene activation and silencing. Think: Here's a long row of dominos all perfectly lined up, where all one has to do is flick over the first one to activate the entire chain, all falling over at a certain speed, depending on spacing intervals, until the last one falls; furthermore, at no time do the dominos right themselves once they have fallen over, so you can't get a reverberating circular loop, as one can with equilibrium (reversible) chemical reactions. However, branching paths or forks in the road (or even paths that come together) are certainly legal options in the language, and that feature of the logic is probably used constantly to synthesize symmetric (left/right) phenotypes of all creatures.]

Regulatory Circuitry in Human Embryonic Stem Cells,"

The transcription factors OCT4, SOX2, and NANOG have
essential roles in early development and are required for the propagation of undifferentiated
Embryonic Stem (ES) Cells in culture. To gain insights into transcriptional regulation of human
ES cells, we have identified OCT4, SOX2, and NANOG target genes using genome-scale
location
analysis. We found, surprisingly, that OCT4, SOX2, and NANOG co-occupy a substantial
portion of their target genes. These target genes frequently encode transcription factors, many of
which are developmentally important homeodomain proteins. Our data also indicate that OCT4,
SOX2, and NANOG collaborate to form regulatory circuitry consisting of autoregulatory and
feedforward loops. These results provide new insights into the transcriptional regulation of stem
cells and reveal how OCT4, SOX2, and NANOG contribute to pluripotency and
self-renewal.

Mr. Johan Beijering, Nursing Home Director said that "she was very clear mentally right up to the end... She said, 'It's been nice, but the man upstairs says it's time to go.'" She once said that the automobile was the greatest technological advance in her lifetime, despite the fact that she never learned to drive and preferred riding her bicycle. She agreed to be autopsied by the University of Groningen in The Netherlands to help scientists learn more about longevity. Mrs. Elizabeth Jones Bolden of Memphis, TN, age 115, is her successor as our World's newest Oldest Person.

August 10, 2005; New York, NY (Malcolm Ritter, Science Writer, AP[3]) -- An
international team of scientists has deciphered the genetic code of rice, an advance that should
speed improvements in a crop that feeds more than half the world's population. It's the first crop
plant to have its genome sequenced, which means scientists identified virtually all the 389
MBP's [millions of base pairs of DNA]. Certain sequences of these building blocks form
genes, like letters spelling words. The advance will help breeders produce new rice varieties with
traits such as higher yield, improved nutritional content and better resistance to disease and pests,
said one of the project's leaders, W. Richard McCombie of Cold Spring Harbor Laboratory in
New York. "I would think this is going to help people find genes and probably enhance the crop
in well under 10 years," McCombie said.
The work is reported in Thursday's issue of the journal Nature [1] by the International
Rice Genome Sequencing Project [2], which was established in 1998 and includes scientists from
ten nations. The effort was led by Japanese researchers.
In the Nature report, scientists estimated rice contains 37,544 genes but said that figure
will no doubt be revised with further research. Humans, by contrast, have only [20,000 - 25,000]
genes. They also said having the genome sequence in hand will be crucial for breeding and
biotechnology advances to increase rice yield, noting that by one estimate the world's rice
production must increase by 30 percent over the next 20 years to keep up with demand. Besides
Japan and the United States, participating scientists came from Brazil, China, France, India,
Korea, Taiwan, Thailand, and the United Kingdom.
Pamela Ronald of the University of California, Davis, who studies disease resistance in rice but
didn't participate in the project, said the sequencing of the rice genome lets scientists do new
experiments to unlock secrets of the plant. "A lot of people are building on this work," she said.
For example, her laboratory used data released earlier from the sequencing project to develop a
way to identify rice genes that become active when the plant deals with stresses like a germ
attack
or drought. That can help scientists track down particular genes for targeting in breeding
programs, she said.

Snuppy, the first cloned dog (R), is an identical twin of Tai, the three-year-old
male, brindle Afghan Hound (L), whose ear cells were used to clone the puppy. Snuppy
was born last April 24th to a surrogate mother bitch, a yellow Labrador Retriever owned by one
of Prof. Hwang's students. Photo: Seoul National University. Note:
Subsequent investigations have unequivocally demonstrated that Snuppy is a genuine
canine clone, so the Nature reference cited below will not be retracted, as have been the
Science articles from 2004 and 2005.
"I had already produced many cloned cows and pigs, but when Snuppy was born, it was
different... I was so happy. He was very healthy."
- -- Woo Suk Hwang with Snuppy
Seoul National University
August 3, 2005; Click on the top photo of Snuppy above for more details from [1-4]. One of the more interesting aspects of this extraordinary accomplishment is that this is really the first time we've gotten a reasonable explanation for why dogs are so hard to clone as compared with other mammals. Genetic Savings & Clone, Inc. has been working on this problem for nearly seven years, first at Texas A&M, later in Sausalito, CA, and most recently in Madison, WI with a team of 50 employees and an accumulated budget of over $19 million. And they were beaten out in this "race" by the Hwang Lab (that spent only US$1 million over two-and-a-half years, using 123 female dogs to create 1,095 embryos). GS&C only got to clone a cat, as a "booby prize," as it were.
Starting with 1,095 embryos (from over 100 donors) and transferring [5 - 12] embryos to each of 123 carefully chosen surrogates, the Huang Lab produced only three pregnancies! One was a still-born [a miscarriage or spontaneous abortion]; another was a full-term puppy, who died of pneumonia after only 22 days; and finally, Snuppy, who was a singleton, full-term [61 days], healthy success story [born by C-section]). This success story took a great deal of perseverance and tenacity (including two years to develop an in vitro cell culture medium hospitable to canine embryos), and the Hwang Lab (a 45-member team) should be rightfully proud.
But to attempt to explain very briefly what's so different about canines: First of all, their eggs do not fully mature in the ovary; they mature "down stream," after ovulation into one of the fallopian tubes, and it's much harder to find these eggs at the right time of maturity. They don't seem to naturally ripen on their own in vitro. Eventually, the team discovered, by brute force and trial-and-error, a signature spike in the hormone Progesterone that signaled the onset of ovulation. Therefore, the whole procedure requires a full surgery with general (not local) anesthesia. To make matters worse, bitches come into season (estrus) only once (or maybe twice) a year, and we don't know how to accelerate the process with pharmacological hormone-regulators, like Lupron, as we can with other mammals, including human females. The same constraint is true for the genetically-unrelated surrogate mothers, in that we cannot prepare the uterine lining with hormones to allow easy synchronized implantation of the embryos.
[ Editorial Remark: Gina Kolata of The New York Times[5] interviewed Ms. Tina Vogel, an Afghan breeder from Norwalk, OH, who ostensibly said, "I am opposed to cloning dogs on the grounds that it would be just like cloning a person. If it was meant to be, God would have done it." A cynical translation of this remark into other words, to better expose the underlying logical fallacy, would be to put it in the same equivalence class as my maiden Aunt Tilly's speculation thirty years ago about why we shouldn't have gone to the moon; in particular, she said "We shouldn't have wasted tax-payer money on going to the moon, given that there are still so many problems right here on Earth. Instead, we should have stayed home and watched television the way God intended us to." Further translation: "If God didn't do it already, it was not meant to be."
On the other hand, we do wear clothes to keep warm next to a cozy fire in the Winter (for which we were capriciously expelled from the Garden of Eden by our Judeo/Christian God and for which Prometheus was subsequently punished by Zeus), we should still be shivering somewhere in a cave trying to figure out how to be obedient little hunter/gatherers, so that we could avoid becoming extinct as a species, also known as not being hungry and starving to death or else being eaten by stealthy predators with exquisitely sharp teeth. So it is especially curious that Ms. Vogel was apparently unaware that God did invent cloning before we did. Cloning commonly takes place in plants and in certain species of insects (ants) and lizards as a standard mode of reproduction. So there, Ms. Vogel of Ohio, take that.]

"Dogs Cloned from Adult Somatic Cells,"
Nature, Vol. 436, No. 7041, p. 641 (August 4, 2005)
Abstract:
Several mammals including sheep, mice, cows, goats, pigs, rabbits, cats{1}, a mule{2}, a
horse{3} and a litter of three rats{4} have been cloned by transfer of a nucleus from a somatic
cell into an egg cell (oocyte) that has had its nucleus removed. This technology has not so far
been successful in dogs because of the difficulty of maturing canine oocytes in vitro.
Here
we describe the cloning of two Afghan Hounds by nuclear transfer from adult skin cells into
oocytes that had matured in vivo. Together with detailed sequence information generated
by the canine-genome project{5, 6}, the ability to clone dogs by Somatic-Cell Nuclear Transfer
should help to determine genetic and environmental contributions to the diverse biological and
behavioral traits associated with the many different canine breeds{7, 8}.

My only quibble here is that the Editors took a cheap shot at Dr. John G. Sperling, Chairman of
the University of Phoenix, without mentioning him by name but referring to him as a "billionaire
who wanted to clone his favorite mutt" [he was uniquely the one who financed the creation of a
pet-cloning company facetiously called Genetic Savings & Clone, Inc. (which has had
dramatic successes and failures of its own over the last five years), with the explicit aim of
cloning
his own pet dog Missy, now deceased, but presumably with tissue frozen in liquid
Nitrogen in some lab.] The "cheap shot" refers to the fact that all billionaires (indeed
all
rich people including those who are merely multi-millionaires) turn out to be extraordinarily self-
indulgent. While they're alive, they like to endow chairs at universities, build buildings with
their
name on it, or entire museums, if they can afford it. But they also routinely buy $10 million
houses in gated communities in different parts of the country, with horse breeding stables,
swimming pools, tennis courts, extra houses on the same property for special guests, yachts,
airplanes, dozens of antique cars, fine art, treasure their privacy by using lawyers as
intermediaries
for all public transactions or donations to the candidates from the political party of their choice,
etc., etc. None of these behaviors, following great wealth, are necessary for achieving happiness.
Furthermore, after they die, they frequently (inadvertently) create Last-Wills-and-Testaments that
cause their living relatives (and/or ex-wives) to fight endlessly over the liquidation of their assets.
But this is the capitalist way. We've already proven that Marx and Engels were wrong to think
that their ideal form of communism could really work in any government in the world in
competition with our beloved capitalism. If we attempt to remind the rich that there are children
starving in Africa (say Niger), they would say, "Tell me something I don't know. I prefer to let
my money "trickle down" to the poor. I have no moral compulsion to do otherwise, do I? So in
conclusion, Sperling's self-indulgent behavior is, in principle, no different from any other rich
person in this country. If he wants a pet cloned of his choice and he can afford it, so be it. It's
not against the law.
And, finally, we do hail Dr. Woo Suk Hwang as the champion cloner for his tour-de-force with
Afghan Hound, Snuppy. It's just that we don't believe the rationale about dogs being
used in medical research. This is way too expensive a solution to a non-existent problem. It was
really a matter of climbing Mt. Everest because it's there. Now that it's been done, hardly anyone
will follow that path. Dog pet cloning can probably not be done profitably at $100,000 a clip
given all the problems that we now know about, so that door will also be closed for a long time
to
come. Cloning a mastodon, using a surrogate female elephant, now that's a challenge! Good
luck, Woo.

July 11, 2005; Answer: Epigentics or Imprinting, the third leg of the three- legged stool of the aging process (the other two, of coursse, are genetics and life-style), is a stochastic process influenced by comic rays and other vagaries of oxidative metabolism over which, so far, we have little control. These random insults attack our genomes as a function of time in the same way the wind and water erode the Egyptian Pyramids over millennia. The longer twins live, the more their genomes diverge. Here is new evidence from the Proceedings of the National Academy of Sciences...

May 30, 2005; Rome, ITALY; A Referendum, that requires 50 percent of the voters in Italy
to pass due to a legal quirk, will be voted in a couple of weeks on June 12-13th. It would repeal
the current law introduced by the center-right government of Prime Minister Silvio Berlusconi
last
December 2003 to overcome some conspicuous abuses that were occurring in a vacuum with no
apparent regulations whatsoever. However, the new law was so onerous that many infertile
Italian couples were leaving the country to get treatment abroad in Greece and other European
countries where conventional IVF procedures were still being practiced. The new law essentially
through out the baby with the bath water. What did it say?
1. Life is defined as beginning at conception. (As a side effect, this would opens up a way to
make all abortions, for any purpose, illegal);
2. Ban sperm donor programs;
3. Ban egg donor programs;
4. Ban surrogate motherhood;
5. Prohibit all research on human embryos. (This would make all attempts at therapeutic, as well
as reproductive cloning, illegal, such as was accomplished in South Korea last week);
6. With regard to IVF as an infertility treatment, only three (3) eggs shall be harvested and
fertilized at any one time, and they must be implanted simultaneously. (This procedure would be
considered malpractice if carried out in the USA and such an OB/GYN infertility doc would be
denied his/her malpractice insurance if not license to practice medicine by the state board with
appropriate jurisdiction);
7. No eggs or fertilized embryos are to be frozen (in liquid Nitrogen). (This would make
impossible an Itallian so-called "snowflake baby," of the sort that President George W. Bush was
happily seen to be kissing in an contrived photo-op on Tuesday, May 24th at the time the House
of Representatives was passing HR 810 to relax his arbitrary constraints on the development of
new stem-cell lines back in August 2001 (thawed and "adopted" for implantation into a
genetically-unrelated surrogate mother).
The Catholic church by way of the Cardinals, the Bishops, and parish Priests has been requesting
its faithful to abstain from voting at all. This would lead to an automatic failure of the
proposition, resulting in a retention of the current law and would be consistent with the new
Pope's Catholic orthodoxy. The Vatican slogan of the Referendum Campaign was "Life cannot
be put to a vote: Don't vote."
We wish to confirm that, when the polls closed on Monday afternoon (14 hours Sunday + 8 hours Monday = 14 hours over a two day period) only 12 million voters of the 48 million eligible voters turned out (26 percent), far short of the 50 percent needed. However, for whatever it's worth, of these 12 million, approximately 3/4ths of them were in favor of the Referendum. So Pope Benedict XVI and his Cardinals/Bishops won by default, and the attempt to ease these onerous fertility laws has failed, at least on this particular round.

Snow flakes at the White House in May?
May 25, 2005; Today, the US House of Representatives passed a Bill to relax the stringent rules on Federal funding of stem-cell research promulgated by President Bush from his ranch at Crawford, TX back in August of 2001. The President stated in prepared remarks in the East Room of the White House, "This Bill would take us across a critical ethical line by creating new incentives for the on-going destruction of emerging human life. Crossing this line would be a great mistake... and I intend to veto it." However, the House Bill did pass and soon will go before the Senate, where its chances are estimated to be reasonably good, in spite of the President's threats to veto this measure. At this point, the availability of the necessary votes needed to override this veto are unclear. Stay tuned.
After delivering his remarks, the President held baby Trey Jones in his arms in a "photo op," as her Mother Tracy Jones glowed adoringly. Click on the President's photo for an icy, flaming GRG Editorial.

Abstract:
Patient-specific, immune-matched human Embryonic Stem Cells (hESC) are anticipated
to be of great biomedical importance for studies of disease and development, and to advance
clinical deliberations for stem cell transplantation. Eleven hESC lines were established by
nuclear
transfer (SCNT; NT) of skin cells from patients with disease or injury into donated oocytes.
These lines (NT-hESCs), grown on human feeders from the same NT-donor or genetically-
unrelated individuals, were established at high rates, regardless of NT-donor sex or age. NT-
hESCs were pluripotent, chromosomally normal, and match NT-patient's DNA. Major
Histocompatibility Complex (MHC) identity of each NT-hESC with the patient's showed
immunological compatibility, important for eventual transplantation. With the generation of
these
NT-hESCs, evaluations of genetic and epigenetic stability can be made. Additional work remains
regarding the development of reliable directed differentiation and the elimination of remaining
animal components. Prior to clinical use of these cells, preclinical evidence is required to prove
that transplantation of differentiated-NT-hESCs can be safe, effective, and tolerated..

It seems that California State Senator Deborah Ortiz (D - Sacramento) has gone over to the "dark
side." I suspect that CalTech President David Baltimore, the member of the Board who
composed the unanimous resolution opposing the Ortiz Resolution, will cross swords (light
sabers) with her again before these delaying tactics are resolved.

Instead of using a needle to suck out the donor egg's nucleus (a routine procedure for standard
enucleation), they made a small tear in the donor egg's cytoplasmic membrane and gently
squeezed out the egg's original chromosomes. They then inserted an entire endothelial (skin) cell
through the lesion followed by the application of a small electric shock fusing the two cells
together in a common cytoplasm (one cell embedded within the other) which in turn triggers the
onset of mitotic division of an egg with a diploid nucleus. This is equivalent to the natural
electrical discharge that typically precludes polyspermie post fertilization by a single (but not by
more than one) sperm (accompanied by a so-called "calcium cascade"). The genetic fingerprint
of
the resulting blastocyst was that of the donated skin cell, not that of the original oocyte proving
that this was definitely not a case of parthenogenesis, in which an unfertilized egg that
begins to divide on its own (immaculate conception?). Furthermore, this cell and all its progeny
when grown in culture on human feeder cells including differentiation down particular pathways
(neuro, myo, epithelial, etc.) would be histocompatible with that of the skin-cell donor and could
be transplanted for therapeutic purposes back into this patient. It would not necessarily be
histocompatible with the young woman who donated the eggs, except in the peculiar case where
they were identical twins.
We should be quick to point out that the value of this approach to preclude a potential massive
rejection of transplanted cells, leading to host death, has not yet been proven. There are some
unconventional practitioners who have denied that any fetal tissue transplanted into an adult
patient would ever be rejected, either by a mechanism of graft-vs.-host or host-vs.-graft, since
this, they say, would be impossible in principle on the grounds that the immune system always
accepts fetal tissues of any type, so long as they are not xenografts (from another species)!
Moreover, it is no guarantee that histocompatible tissues from a identical twin but of a radically
different age (10-day embryonic tissue vs. 20,000-day adult tissue) would still not be rejected.
Adult immune systems may seek to reject any fetal or embryonic tissues whatsoever, as a defense
against what looks to it like a cancer under development. Lastly, a requirement for
immunosuppressive drugs either for a short time (or for a lifetime) is rather unclear at this point.
Consider the side effects of this. Finally, to make matters worse, there are multiple
submechanisms possible for rejection, some of which involve Killer T-cells that trigger apoptosis
(anaphylactic shock) and the thymic gland, which is largely involuted by the onset of adulthood,
and B-cell antibody defenses that may smolder in the background, and therefore may slowly kill
off the new cells. One needs to know if one or the other or both of these mechanisms is
operating
before one can confidently say that stem-cell administration as a therapy fits in the same simple
category as Red Cross style cross-matching a patient for transfusion (four types: A, B, AB, and
O). The organ-donation HLA-type-and-cross-match business is exceedingly complex compared
with what the blood-banking industry has become today, independently of the obvious supply
and
demand issues.

Nobel Prize Laureate, CalTech President, Prof. David Baltimore said, as he prepared to meet
with
legislators, "I don't know what her [California State Sen. Deborah Ortiz (D - Sacramento)]
motivation is, but I know the result is extremely dangerous and could undermine the whole
reputation of our state as a leader in stem-cell research." Curiously, Ortiz's Bill is backed by
Senate Republicans, rather than fellow Democrats, whose endorsement is largely based on
ideological opposition to embryonic stem-cell research rather than a disingenuous interest in the
poor citizens of California. Joseph Dunn (D. Santa Ana) said, "In my view there are many
Republicans who would like to slow [Prop. 71] down and end it as a first choice. That's fine. I
respect their view. But this was established by the voters of California, and we need to respect
their wishes." "There may be a Senate vote on Thursday," according to Senate President Pro
Tem Don Perata (D. Oakland).
[ Editor's Note: How dare Ortiz cross swords with Baltimore? Ortiz couldn't carry

must

May 4, 2005 ( BBC [1]); The scientists looked at cells found on the surface of ovaries. Early stage human eggs have been developed from stem cells for the first time, US researchers have revealed. Researchers from the University of Tennessee claim the laboratory research could help women with premature menopause or fertility problems. And they suggest in Reproductive Biology and Endocrinology that it could lead to the natural menopause being delayed by up to twelve years. But a leading UK expert cautioned the work was still at a very early stage. "This research is at a very early stage and needs to be confirmed," said Dr. Simon Fishel, Director of Care Fertility. Women have around two million egg-producing follicles in their ovaries when they are born. But by the time they reach puberty the number has fallen to about 400,000. The number of follicles continues to fall until her menopause, at which point she will no longer be able to produce a mature egg capable of being fertilized.
'Easily Harvested'
However the Tennessee researchers found ovarian stem cells could develop into new eggs. They took Ovarian Surface Epithelium (OSE) cells from the outside of the ovaries of five women aged [39 - 52]. They were then grown in a lab for five to six days. Some were exposed to a growth-stimulating oestrogen medium called phenol red. Those cells which were cultured without this medium differentiated into immature small cells of various different types. But those exposed to phenol red completed the first stage of the division needed to become mature human eggs, capable of being fertilized and developing into an embryo. The team said that the OSE cells can be easily harvested from the surface of the ovaries, using a laparoscope, a flexible telescope-like instrument. They said the discovery could help those women with poor fertility or who are set to go through an early menopause, who lack follicles in their ovaries, to have a better chance of conceiving through IVF. They predicted that eventually, frozen OSE cells from younger women could be preserved for later production of fresh eggs, potentially preventing the risks linked to pregnancies in older women which naturally have to use mature eggs. And being able to produce new egg and granulosa stem cells may enable the development of new ovarian follicles. The team claim this could lead to a 10- to 12-year delay of the onset of natural menopause.
Possibilities
Prof. Antonin Bukovsky, who led the research and is Editor-in-chief of Reproductive Biology and Endocrinology, wrote: "Development of numerous mature oocytes (eggs) from adult ovarian stem cells in vitro offers new strategies for the egg preservation, IVF utilization, and treatment of female infertility." They added that fertilized laboratory-grown eggs could also provide embryonic stem cells for other medical applications and basic research. Dr Fishel told BBC News On-line: "Other research has shown it's very difficult to get eggs that exist at an immature stage to become viable. And here, we're going back to an enormous stage even before that." But he added, "If it is confirmed, it is possible that it could help pre- menopausal women and women coming up to their menopause having IVF, who currently need to use egg donors. "This could mean they could have a baby using their own genetic material."
Ten years ago, we reported that in adult human females the Ovarian Surface Epithelium (OSE) is a source of germ cells. Recently, we also demonstrated that new primary follicles are formed by assembly of oocytes with nests of primitive granulosa cells in the ovarian cortex. The components of the new primary follicles, primitive granulosa, and germ cells, differentiated sequentially from the OSE, which arises from cytokeratin positive mesenchymal progenitor cells residing in the ovarian tunica albuginea. In the present study, we investigated the possibility that the oocytes and granulosa cells may differentiate in cultures derived from adult human ovaries. Cells were scrapped from the surface of ovaries and cultured for 5 to 6 days, in the presence or absence of estrogenic stimuli [Phenol Red (PhR)]. The OSE cells cultured in the medium without PhR differentiated into small (15 micron) cells of granulosa phenotype, and epithelial, neural, and mesenchymal type cells. In contrast, OSE cells cultured in the presence of PhR differentiated directly into large (180 micron) cells of the oocyte phenotype. Such cells exhibited germinal vesicle breakdown, expulsion of the polar body, and surface expression of zona-pellucida proteins, i.e., characteristics of secondary oocytes. These in vitro studies confirm our in vivo observations that in adult human ovaries, the OSE is a bipotent source of oocytes and granulosa cells. Development of numerous mature oocytes from adult ovarian stem cells in vitro offers new strategies for the egg preservation, IVF utilization, and treatment of female infertility. In addition, other clinical applications aiming to utilize stem cells, and basic stem cell research as well, may employ totipotent embryonic stem cells developing from fertilized oocytes.

April 28, 2005; Born on March 13th, Paris Texas, the first cloned foal in the US was announced by Texas A&M University researchers at College Park, TX [1]. (A female horse was previously cloned in Italy.) It took over 400 attempts over a six-month period. Six embryos were created, and one of them was successfully brought to term in a surrogate mare named Greta. The pregnancy took 12 1/2 months. (The normal gestation time for horses is 11 months.) Texas A&M had previously cloned pigs, a Boer goat, an Angus bull, a Brahma bull, and a deer.
This month, a French-Italian collaboration announced the successful birth of a foal cloned from a gelding. Now two months old, the foal was produced by the French genetic engineering company Cryozootech and the Italian reproductive technology lab LTR-CIZ. The lab's team, headed by Cesare Galli, has improved on techniques it used two years ago to produce the first horse clone, a mare. From 200 nuclear transfers using skin cells from Pieraz, a retired thoroughbred Arabian endurance champion, the researchers got 34 embryos and three pregnancies, one of them successful. [2]
Galli has predicted that cloning will revolutionize the horse-racing industry. But at present, the thoroughbred racing community doesn't even permit artificial insemination, much less cloning. Paul Struthers of Britain's Jockey Club says racers have a very restricted gene pool and "there would be very serious implications for the long-term welfare of the thoroughbred were the gene pool to be reduced further" by breeders all going after the progeny of superachievers. But cloning could have a future with horses intended for show jumping, dressage, or endurance racing events with fewer breeding restrictions. "Over 90 percent of dressage stallions are gelded to make them more manageable," [So, that's why they do it. I could never figure out why anybody would ever want to geld a race horse just by common knowledge from reading the sports pages, since, obviously, I'm not an insider in this particular sandbox.] says Nicolas Robin of Cryozootech: "So imagine how many gene lines are lost." But no longer. The company is preserving cells from some 30 prize stallions and plans to market semen from their clones.

April 26, 2005; The US National Academy of Sciences and the Institute of Medicine have issued a 131-page Report with Ethical Guidelines for Research using Embryonic Stem Cells. These guidelines will almost certainly be adopted by the Institute on Regenerative Medicine in connection with its own grant process for stem-cell research in California. We expect to prepare an editorial describing our differences with these guidelines, if any, by the end of the week. At a first glance almost all the guidelines would seem to be acceptable to our group with the exception of whether scientists can pay human subjects to donate eggs above and beyond their normal medical expenses (hormones, syringes, ultra sound exams, surgery to harvest eggs from the ovaries, anesthesiology) in connection with the institutionally approved donor egg program.

Los Angeles Councilmen Jack Weiss and Martin Ludlow led an hour-long hearing into why the
City of Los Angeles bid was rejected on a technicality, particular whether Mayor James K.
Hahn's deputies made an 'irrevocable lease offer' for the required office space. "I read English.
Where does it say that?" asked Weiss rhetorically, questioning Deputy Mayor Renata Simril on
where it was spelled out explicitly. However, the answer that 'the Council's Resolution was
equivalent to such an offer, a practice that has been accepted on state bids in the past' was
unconvincing. Council members loyal to the Mayor suggested that "the hearing was unnecessary
and that nothing useful came out of it." "It was shameful," Tim McOsker said, as he left the
meeting. However, Weiss castigated the Mayor's staff: "We lost thousands of jobs, millions of
dollars in economic development related to savings countless lives, and at the end-of-the-day
they
said they 'wouldn't have changed a thing.' That's simply astonishing!"

It appears that "big pharmas" (large, international, publicly-held companies) are exquisitely
sensitive to investor demonstrations suggesting that they may be do something immoral
(if not illegal) and its subsequent implications for a tank in their stock price. However,
the fact that they are hedging their bets with potentially large capital resources, even if only in
small ways, tells us that we're on to something important. It would be a shame if the universities
were the pioneers (the one's who get all the arrows in their backs) just so that the pharmas can
come behind and take all the credit and glory later on, without sharing in the early-adopter
risks.

Abstract:
Forecasts of life expectancy are an important component of public policy that influence age-based entitlement programs such as Social Security and Medicare. Although the Social Security Administration recently raised its estimates of how long Americans are going to live in the 21st century, current trends in obesity in the United States suggest that these estimates may not be accurate. From our analysis of the effect of obesity on longevity, we conclude that the steady rise in life expectancy during the past two centuries may soon come to an end.

March 8, 2005; United Nations; New York City ( UN News Centre) The United Nations General Assembly today approved a non-binding declaration calling on all UN Member States to ban all forms of human cloning, including cloning for medical treatment, as "incompatible with human dignity and the protection of human life." By a vote of 84 in Favor, 34 Against, and 37 Abstentions, with 36 Absent, the Assembly acted on the recommendation of its Legal, or Sixth Committee to adopt the text, called The United Nations Declaration on Human Cloning. But some delegates said they opposed banning therapeutic cloning. The Declaration, negotiated by a Working Group last month, also banned "genetic engineering techniques that may be contrary to human dignity."

March 8, 2005; Worcester, MA; ACT has reported in Lancet a system for growing embryonic stem cells that markedly reduces the risk of contamination with pathogens (particularly murine viruses) that could be transmitted to patients and the population-at-large. The extracellular-matrix-coated plates used in ACT's study proved remarkably stable, and could be easily sterilized using a variety of conventional treatment and sterilization processes. This work also represents a step toward completely animal product-free culture system for the derivation and maintenance of new "clean" embryonic stem cell lines.

Abstract:
Background: Human embryonic stem cells are likely to play an important role in the
future of regenerative medicine. However, exposure of existing human embryonic stem-cell lines
to live animal cells and serum risks contamination with pathogens that could lead to human
health risks. We aimed to derive an embryonic stem-cell line without exposure to cells or
serum.
Methods: Frozen cleavage-stage embryos were thawed and cultured to the blastocyst
stage. Inner cell masses were isolated by immunosurgery and plated onto extracellular-matrix-
coated plates that can be easily sterilized. Six established human embryonic stem-cell lines were
also maintained with this serum and feeder-free culture system.
Findings: A new stem-cell line was derived from human embryos under completely
cell- and serum-free conditions. The cells maintained normal karyotype and markers of
pluripotency, including Octamer-Binding Protein 4 (Oct-4), Stage-Specific Embryonic Antigen
(SSEA)-3, SSEA-4, Tumor-Rejection Antigen (TRA)-1-60, TRA-1-81, and Alkaline
Phosphatase. After more than six months of undifferentiated proliferation, these cells retained the
potential to form derivatives of all three embryonic germ layers both in vitro and in teratomas.
These properties were also successfully maintained (for more than 30 passages) with the
established stem-cell lines.
Interpretation: This system eliminates exposure of human embryonic stem cells and
their progeny to animal and human feeder layers, and thus the risk of contamination with
pathogenic agents capable of transmitting diseases to patients.

March 2, 2005; Stanford, CA; Prof. Zach W. Hall, Ph.D., Associate Dean at the Keck School of Medicine at USC has been named interim President of the State's new $3-billion stem- cell agency. The 29-member Public Oversight Committee charged with creating the agency voted unanimously to hire Hall, 67.
Formerly, Hall was President and CEO of Envivo Pharmaceuticals, Inc., a start-up, biotechnology company focused on using simple organisms to discover drugs for neurodegenerative disease. From 1997 to 2001, he was Executive Vice Chancellor at the University of California at San Francisco, where he was responsible for planning the new 43-acre UCSF Mission Bay campus, which is part of a 300 acre public/private biomedical research park. He also oversaw research administration at UCSF, including the Office of Industry and Research Development, dealing with technology transfer and industry relations.
Dr. Hall received his undergraduate degree in English from Yale University and a doctoral degree in Biochemistry (Medical Sciences) from Harvard University. Following a post-doctoral Fellowship at Stanford University, he joined the faculty in the Department of Neurobiology at Harvard in 1968, where he remained until moving to the University of California at San Francisco in 1976. From 1994-97, Hall was Director of the National Institute of Neurological Disorders and Stroke (NINDS) at the NIH, where he presided over a major reorganization of intramural and extramural research programs. NINDS is the leading Federal research agency supporting research on the nervous system and its diseases. At the time Hall was Director, the agency had an annual budget of $780 million and employed over 700 scientists and administrators. Before going to NIH, Hall was Chair of the Department of Physiology at UCSF and Head of the Biomedical Sciences Graduate Program.
Hall has been a member of the Medical Advisory Board of the Howard Hughes Medical Institute and of the Dana Alliance for Brain Initiatives. He is Chair of the Scientific Advisory Committees for the National Neurofibromatosis Foundation and of the Searle Scholars Program. He is an elected member of the Institute of Medicine, the American Academy of Arts and Sciences, and an Honorary Member of the American Neurological Society. He has published more than 100 research papers and reviews, is the author and Editor of the widely used textbook An Introduction to Molecular Neurobiology and served as Founding Editor of Neuron, a leading neurobiological journal.

February 15, 2005; Cats exist on nearly every continent, where they occupy the top of the food chain where ever they live. House cats were first domesticated about 6,000 years ago (dogs about 12,000 years ago). But the Cat Genome Project will be done next, after which come the elephant, the orangutan, the shrew, the hedgehog, the guinea pig, the tenrec, the armadillo, and the rabbit (So, where on this list is the bat, the most numerous mammal on our planet?). The work is to be done by Agencourt Bioscience Corp. of Beverly, MA under contract to the NIH National Human Geonome Research Institute for about $5.5 million and be completed as soon as this Summer but maybe not until the end of the year, depending on how things go. Even though the sequencing is largely automated at every stage, there are still a lot of labor-intensive steps, and there will be more than 100 people involved in the project in one way or another.

She discussed her third son, Robert, who was born with a physical handicap. Another of her sons, Horace, 82, interviewed her, discussing her early life in New England, pioneering in Idaho, school, family, singing in a Messiah Choral Group, and the war years. At the age of 102, she wrote a book about the interesting incidents in her life entitled, Ripples on a Quite Stream: The Story of the Life and Times of Marion Bigelow Higgins (122 pages; 2003). Marion, who has a keen mind and a great memory, has participated in several memory walks put on by The Alzheimer's Association in Orange County. Thelma Kramar, Marion's writing teacher, took turn with Horace pushing her wheel chair. They have also participated in the yearly walk-a-thons in support of The Golden Age Foundation. Quilt-making was Marion's hobby, but unfortunately, she had to give it up due to failing eyesight.

February 10, 2005; Dr. Leroy Hood, former Chairman of the Biology Division at CalTech, is recognized as one of the world's leading scientists in molecular biotechnology and genomics. Dr. Hood along with colleagues developed the DNA Gene Sequencer and Synthesizer, and the Protein Sequencer and Synthesizer - which comprise the technological foundation for contemporary molecular biology. He was also one of the first advocates of and is a key player in the Human Genome Project. Dr. Hood has also played a role in founding numerous biotechnology companies, including Amgen, Applied Biosystems, Systemix, Darwin, Rosetta, and MacroGenics. In 2000, Dr. Hood co-founded the Institute for Systems Biology in Seattle, WA to pioneer systems approaches to biology and medicine. He serves as President of the Institute and continues to actively pursue his interest in biology, medicine, technology, development, and computational biology.
One of our GRG Co-Founders, Dr. Robert Nathan, asked Dr. Hood during the Q&A Session
that followed his lecture,
"But what about aging, which you hardly mentioned in your talk?
Shouldn't that receive some special focus of attention in the new Systems Biology?"
Hood replied: "We've made some spectacular progress in aging research using model organisms
like C. elegans and Drosphila. Next, we have to apply this knowledge to
humans. I predict that, by applying the principles of Systems Biology, in ten years we
can expect to see a 10- to 20-year increase in average life expectancy for the general population.
In ten years, with the cost of DNA sequencing coming down by another 100,000-fold due to
advances in technology, every single person in this room, who wishes, will have their unique
DNA
sequence routinely placed in a computer data base that will lead to custom therapeutic
interventions that are tailored to their individual, idiosyncratic genes."
February 10, 2005; The cloning of two cats for sale by Genetic Savings & Clone of Sausalito, CA has prompted an outcry by animal-rights activists. Assemblyman Lloyd Levine, (D -- Van Nuys, CA) has taken up their cause with a bill that would outlaw cloned dogs, cats, birds, and fish in California, including those fish that have been genetically modified. Separately, Genetic Savings & Clone has announced that they have opened a new lab near Madison, WI with the aim of cloning a dog within 12 months, the one long-term goal that has so far eluded them. [1]
February 10, 2005; San Francisco, CA ( Reuters) -- A California lawmaker said on Wednesday he would introduce a bill this week to ban sales of cloned pets, a move that could end a California company's plans to replicate beloved domestic animals. "A ban is necessary because the technology is unregulated and animal shelters are filled to capacity with potential pets," Assembly Member Lloyd Levine said in an interview. "If you were to use animals for experiments, for agriculture, for all sorts of things, there are all sorts of regulations ... Who knows what's going to happen if these things get released into the wild?," Levine said.
The proposal follows the first pet cloning last year from Sausalito, CA-based Genetic Savings & Clone, Inc., which charges $50,000 to clone a cat. The company in December revealed it had cloned a cat -- named Little Nicky after its progenitor Nicky -- for a client in Texas. [Scroll down to see last year's story dated October 10, 2004]. "Why do we need to pay $50,000 for a cat?" Levine said. "We're not banning legitimate scientific research. We're simply banning the exploitation of vulnerable people." The privately-held company says it has four other cat clones in various stages of production and is developing a dog-cloning service.
"The proposed ban is based on myths and science fiction and would neither improve animal welfare nor serve the interests of consumers," said Ben Carlson, a spokesman for Genetic Savings & Clone. "I have the impression Levine is pandering to animal-rights advocates." [2]
[ Editorial Remark: "GloFish" are actually Zebra Fish with an additional gene inserted to make them glow green developed by Yorktown Technologies, L.P. Years ago, I worked for a veterinarian for one year in his clinic, and I have a broad range of experience with cats and dogs, as well as their owners. I bred Afghan Hounds at one time and have owned a cat as well. There are plenty of laws on the books to prevent the abuse of pets, and we don't need any new ones. The holier-than-thou animal-rights activists who are writing these anti-pet-cloning laws are really "slippery-slope anti-technologists" in disguise, and we need to expose their true agenda for what it is. The ASPCA has not yet made a decision on this matter but is expected to do so shortly. Even if you don't live in California, if you are a pet owner, why don't you write to them and take a stand? Also, while you're at it, by way of a show of support and as a protest against the "animal-rights activists," and providing that you don't live in California, why don't you purchase some GloFish yourself by clicking on this GloFish.com link. This link will also lead you to copies of all the scientific analysis by the US FDA and the State of California Department of Fish and Game approving their ownership by fish fanciers and acknowledging their lack of any hypothetical threat to the environment, which was a grave concern by environmentalists a couple of years ago when they were first introduced for sale. - - Steve Coles, News-Section Editor GRG.ORG]

February 10, 2005; More than one million dollars was spent by the University of Pennsylvania to settle fraud allegations related to the death of a teenager during a gene therapy experiment. Jesse Gelsinger, 18, of Tucson, AZ died in late 1999 after he suffered catastrophic anaphylactic shock following an unexpected massive immune rejection of the viral capsid of the vector used to transport a gene that would have corrected a mutated version that he inherited causing a liver-enzyme failure that blocked his body's ability to process Nitrogen normally ( Ornithine Transcarbamylase Deficiency)[3]. (Other patients had not exhibited this sort of rejection of the vector.) After his death, Gelsinger's family said the teen had not truly given informed consent and was, in fact, misled about the experiment's potential risks. The Children's National Medical Center and the University have maintained that this death was completely unforeseen and that he was properly enrolled in the study based on the best scientific information available at the time. Neither institution was required to acknowledge any wrongdoing as part of the settlement. The family had already settled a "wrongful-death" lawsuit against the teen's doctors and the University of Pennsylvania in the year 2000, the terms of which were never disclosed as part of the settlement. More about the legal decision can be found in [4, 5].
[ Editorial Remark: This tragic story of Jesse Gelsinger's death should have had a different ending. We should be remembering him proudly, as a pioneer, whose example helped to teach us some new science. Instead, we only remember his greedy parents, who helped to crush progress in this nascent field of genetic engineering on the grounds that the attending physicians, working at the cutting edge of medicine, did not do their job of properly enrolling this young boy into their protocol, something that we can't tell from what has been disclosed publicly. Didn't they carefully explain all the attendant risks, including the possible death of the subject? The paperwork was duely signed by him in advance (or they wouldn't have done it), and he was of age to sign on his own behalf, wasn't he? Dr. James Wilson said the fatal reaction was a surprise, and he also denied any financial conflict-of-interest with regard to this experiment. But investigations by The Washington Post and by the Food and Drug Administration during the following months revealed multiple scientific and ethical lapses that undermined those assertions. Among them were unreported deaths of monkeys given similar treatments; the failure to inform the FDA, as required, when patients became so ill from the treatment that, according to FDA rules, the study should have been suspended; and Wilson's failure to disclose that a company in which he had a strong financial interest stood to profit if the treatment was successful. It also came to light that, under the study guidelines, Gelsinger was too sick to get the treatment, but he was treated anyway. Therefore, there were a lot of mitigating circumstances for all parties. But, that's never enough when things don't go your way, and you have good lawyers. Hopefully, now the University can go back to its normal work, after being properly reprimanded.]

February 8, 2005; London and Edinburgh, UK ( AP) -- Prof. Ian Wilmut, the creator of
Dolly the sheep has been granted a license to clone human embryos for medical research,
authorities in London have announced. Dr. Wilmut of the Roslin Institute in Edinburgh and a
team from King's College, London plan to clone embryos to study Motor Neuron Disease.
Consent for the cloning to treat the incurable muscle-wasting condition was granted by Britain's
Human Fertilization and Embryology Authority (HFEA).
[ Editorial Remark: We are delighted to see that one of the world's recognized figures in the field is getting to do work that will teach us a lot about the presumed promise of this field, even though, in our view, the particular strategy proposed by Drs. Wilmut and Christopher Shaw of the Institute of Psychiatry at King's College London is unlikely to yield a cure for Lou Gehrig's Disease (Amyotrophic Lateral Sclerosis). We suspect that neurons differentiated from Embryonic Stem Cells derived from patients having the disease are more likely to appear perfectly normal compared with controls than to exhibit a pathonomonic marker for the disease. To our knowledge, there is no significant inherited (genetic) component to this debilitating, fatal disease. Nevertheless, we would expect to see many valuable details published about chemokines for differentiating stem cells in vitro that would be extraordinarily important for all future work in this field, and they are clearly laying the ground work in the context of officially-sanctioned Government approval.
One the other hand, there are people out there who are completely misinformed about the medical significance of this work on some sort of moral grounds. One egregious example, is the London-based ProLife Alliance, which has pronounced that "All human cloning is intrinsically wrong and should be outlawed. The creation of cloned human embryos destined for experimentation and subsequent destruction is particularly abhorrent." Well, ladies and gentlemen of the ProLife Alliance, I find your paradoxical view of life to be self-contradictory. It seems to me that your Alliance is distinctly "AntiLife" rather than "ProLife," else how are we to cure diseases in the future? (which you may or may not be in favor of, I'm not sure). Your Manifesto on the Internet [4] (a panopoly of loose thinking) doesn't make this clear. However, I suspect that the real issue is not that you are in favor of disease, but that you subscribe to the discredited notion that human "personhood" begins at conception (and that any deliberate destruction of a fertilized egg constitutes murder, which is a fallacy about which you need to be re-educated, and I challenge you to debate this issue at any time and place of your choosing.

January 27, 2005; Rats bred for low aerobic capacity really seem to suffer from poorly-functioning mitochondria. These rats will die sooner than controls.
Refs.:

Science, Vol. 307, No. 5708, pp. 334-5 (January 21, 2005).
"Try as we might, only an elite few will ever win the Tour de France or even the local 10-K
foot race. People simply vary widely in their ability to perform aerobic exercise. New work with
rats now suggests that individuals with a low tolerance for aerobic exercise may have a lot more
to worry about than just their inability to run fast and long. The same underlying defect that
reduces aerobic capacity may also predispose a person to a witch's brew of medical problems that
could increase the possibility of heart attacks and strokes.
Ulrik Wislff of the Norwegian University of Science and Technology in Trondheim,
Sonia Najjar of the Medical College of Ohio in Toledo, and Steven Britton of the University of
Michigan, Ann Arbor, reports that rats that have been selectively bred to have reduced capacity
for aerobic exercise show obesity, resistance to the hormone insulin (a sign of Type-II Diabetes),
and high blood pressure, all symptoms of the so-called metabolic syndrome that raises the risk of
cardiovascular disease. The researchers also provide evidence that impaired function of the
mitochondria, small structures that produce most of a cell's energy, underlies the metabolic
problems of the rats with low aerobic capacity.
Previous work had implicated poor mitochondrial function with individual components of
metabolic syndrome, but this is the first time researchers have linked it to all of them at once.
"This is an incredibly provocative study," says Vamsi Mootha of Massachusetts General Hospital
in Boston, whose own work has linked mitochondrial malfunction to Type-II Diabetes. "They
linked metabolic syndrome to mitochondria in a way that hasn't been done before."
Running for their lives, these rats, bred to have high aerobic capacity, appear to have fewer
cardiovascular risk factors than their couch-potato cousins..."

January 24, 2005; In the January 30th issue of Nature Medicine (Vol. 11, pp. 228-
32), Prof. Fred Gage of the Salk Institute in La Jolla, CA writes that "whenever a Sialic
Acid (in particular, N-glycolylneuraminic Acid or Neu5Gc for short), which is
commonly found in other mammals but not in humans, is eaten by way of meat or milk, it is
immediately destroyed by host antibodies (as a foreign protein)." This latest work demonstrates
that these antibodies, found in human plasma, will, in fact, kill stem-cells from the standard,
NIH-approved lines in vitro. It is expected that were these cells injected into humans,
the
same destruction would occur in vivo. To fix the problem, one could go down one of
two hypothetical paths: (1) Start over and develop properly sterile human lines that do not make
use of mouse feeder cells or calf blood serum, normally used to facilitate all stem-cell
development in vitro; or (2) If you believe, for religious reasons, that developing new
embryonic stem-cell lines is tantamount to murder (sic) or if you work outside of
California and depend on NIH funding (sigh!), labor to purify the existing lines.

alternative, we wish you good luck!]

Lines" (January 24, 2005.
Human Embryonic Stem Cell (HESC) Lines cultured with animal-derived products have become
contaminated with N-glycolylneuraminic Acid (Neu5Gc), a Sialic Acid that human
cells
are genetically unable to make, according to a new report. Because humans normally express
antibodies to Neu5Gc, these contaminated cells would be dangerous if used
clinically.
All HESC lines currently approved for study under Federal funding in the US have been
grown on or derived from a mouse feeder layer. HESC lines grown on mouse-feeder cells
and in culture media containing animal products become contaminated through a "Trojan Horse"
type of mechanism, Senior Investigator Dr. Ajit Varki, of the University of California San Diego,
told Reuters Health. The cells take up Neu5Gc-containing molecules, which are
delivered to the lysosome where they are released and delivered to the cellular metabolic
machinery.
Writing in the journal Nature Medicine published on-line January 23rd, Dr. Varki and
his colleagues note that approximately [6 - 10.5] percent of total Sialic Acids in HESCs are made
up of Neu5Gc. Attempts at growing contaminated cells on animal-free feeder systems and
in heat-inactivated human serum have failed to remove all traces of Neu5Gc. If used in humans,
"there is a significant chance of a deleterious immune reaction and/or rejection of the
transplanted
cells," Dr. Varki said. "Either more needs to be done to figure out how to eliminate this problem
or we have to start over with new stem cell lines" that are never exposed to animal-derived
products, the researcher said, an option that "generates a lot of political and policy concerns."

Abstract:
Aberrant transcriptional repression through chromatin remodelling and histone deacetylation has
been postulated to represent a driving force underlying tumorigenesis because histone
deacetylase
inhibitors have been found to be effective in cancer treatment. However, the molecular
mechanisms by which transcriptional derepression would be linked to tumor suppression are
poorly understood. Here we identify the transcriptional repressor Pokemon (encoded by
the Zbtb7 gene) as a critical factor in oncogenesis. Mouse embryonic fibroblasts lacking
Zbtb7 are completely refractory to oncogene-mediated cellular transformation.
Conversely, Pokemon overexpression leads to overt oncogenic transformation both in
vitro and in vivo in transgenic mice. Pokemon can specifically repress the
transcription of the tumor suppressor gene ARF through direct binding. We find that
Pokemon is aberrantly overexpressed in human cancers and that its expression levels predict
biological behavior and clinical outcome. Pokemon's critical role in cellular transformation
makes
it an attractive target for therapeutic intervention.
"Scientists Identify a Single 'Master' Gene That Seems to Turn On Cancer"
by
Delthia Ricks
Newsday
An international team of scientists believes it has found cancer's master switch with the discovery of a gene they dubbed "Pokemon." Like the electronic game figures - tiny monsters with bad tempers - the cancer-triggering gene apparently instigates the misbehavior of other cancer-causing genes, leading to tumor formation. In today's issue of the journal Nature, researchers at Memorial Sloan-Kettering Cancer Center in Manhattan, in collaboration with teams in Japan and Britain, announce that the gene plays a key role in starting a malignancy. As a result, scientists now believe they have stumbled upon an important new target for an anti-cancer drug.
Dr. Carlos Cardon-Cardo, a molecular pathologist at the cancer center and a senior author of the research, defined Pokemon as an oncogene, which means it is capable of causing cancer. Dozens of oncogenes have been discovered over the past 25 years. But unlike the others, Cardon-Cardo said Pokemon has a governing role -- it is needed for other genes to function. "Eliminate Pokemon," he said, and "you stop the activity of other cancer-causing genes."
January 18, 2005; With a bizarre series of ad hominem arguments and a patronizing tone, the Editors of the otherwise cutting-edge magazine Technology Review, have decided to post Aubrey's photo on their cover like an FBI Most-Wanted Poster and send him off to an institution for the insane on the grounds that "he's nuts." The unflattering close-up cover photo has a caption which asks the provocative question "Is he nuts?" while the Table of Contents on Page 3 presumes to answer this question "... [We] found him brilliant --- but also nuts." Can Aubrey, one of our more energetic spokesmen, really be a "troll," a slovenly dresser, sporting a Rip-van-Winkle beard (I might have said Rasputin), lacks children, drinks too much beer, shows signs of decay at the age of 41, and spends way too much time on his obsession?[1] Sure he can. We always knew that Aubrey had a certain "studied look." But how can he have the arrogance to attempt to "perturb" our assumptions about biological longevity? That's impossible, isn't it?

January 18, 2005; Bucharest, ROMANIA - A 66-year old Romanian professor, who writes children's books, claims to have become the world's oldest woman to give birth, and doctors said she and her day-old daughter were in good condition at Giulesti Maternity Hospital. Doctors said that " Adriana Iliescu, who is single, became pregnant though in vitro fertilization (IVF) using sperm and egg from anonymous donors." They said "she delivered her first child, 3-lb. 4- oz. Eliza Maria, by C-section on Sunday but that a twin sister was stillborn."
________________January 17, 2005; Bucharest, ROMANIA ( The Times of London) -- A retired professor yesterday became the oldest woman in the world to give birth - at the age of 66. Adriana Iliescu, who was due to have twins next month, had a girl Eliza Maria. Her pregnancy was induced after a[n ultrasound] scan revealed one of the children had died.
Doctors feared for the safety of he second twin but she was born weighing 1.4 Kg (3 lbs.) and 'in perfect health.' "Ms. Iliescu's age was probably unrelated to the other twin's death," said doctors in the Romanian capital, Bucharest. 'The Mother is doing well -- she's saying she has been given a new lease of life,' added hospital staff.
Josephine Quintavalle, for The ProLife Party, said 'a child deserved a mother and father who 'will be around for as long as possible.' Ms. Iliescu had nine years of hormone treatment to delay her menopause before becoming pregnant. The egg was fertilized with donor sperm.
Last month, she said 'I worked so hard in my career that I had no chance to start a family. 'A woman has a right to give birth, and I had to follow my dream - no matter how old I was.'
Previously, the oldest woman to give birth was Satyabhama Mahapatra, a 65-year-old Indian who was impregnated in 2003. The British record is held by hill farmer Liz Buttle. She had a son, Joe, in 1997 at 60 after lying about her age to receive fertility treatment. [2]
Many experts warn of the risks of becoming pregnant after age 50 because of physical stress to the mother and baby.
[ Editor's Note: Dr. Richard Paulson, OB/GYN Infertility Specialist from USC was a speaker to the LA-GRG on July 29, 2003 and was featured on Nova Special covering this topic. One of Dr. Paulson's more famous patients (Mrs. Arceli Keh) deliberately concealed her true age (60), representing herself to USC as 50 years old (the age limit for surrogate mothers receiving donor eggs under the protocol was set at 55). She subsequently became the oldest woman in the world at that time (63), to give birth. Fortunately for everyone concerned, her infant turned out to be a healthy baby girl! [3]]

" Assemblages resulting from combining an ES cell-derived egg or sperm with
normally
produced sperm or egg via in-vitro fertilization (IVF) are entities distanced not only from the
physiological reproductive process but from human forebears with any socially prescribed
responsibility for them."
Response by Giuseppe Testa and John Harris, "It is not the enabling technology, but the choice of
the word "assemblage," in its objectifying power, that distances potential humans generated
through [ES-Derived Gametes] from the rest of society. Creatures born through ESDGs
would be humans just like anybody else, whether conceived naturally or through [in vitro
fertilization]."
January 18, 2005; London, UK ( Reuters) -- Three teams of scientists have identified a genetic mutation that is linked to about five percent of inherited cases of Parkinson's Disease. Te fault on the recently discovered LRRK2 gene is one of five genetic defects liked to the progressive nervous-system disorder and could lead to improved diagnosis and the development of a genetic test.
"Our results suggest that the mutation we have studied is the most common cause of Parkinson's Disease identified to date," said Tatiana Foroud, an Associate Professor at Indiana University School of Medicine in Indianapolis. The research is one of three studies by scientists in Britain, The Netherlands, and the U.S. who identified the LRRK2 gene mutation. Their findings are being published in the on-line issue of Lancet today.
