Vaccines and Production
of Negative Genetic Changes in Humans
(c) 1996-1998 Leading Edge Research Group
Vaccination and Genetic Change: Mobility of Genetic Material Between
Life Forms:
One of the indications that vaccinations may in fact be changing the
genetic structure of humans became evident in September of 1971, when
scientists at the University of Geneva made the discovery that biological
substances entering directly into the bloodstream could become part of human
genetic structure. Originally, Japanese bacteriologists discovered that
bacteria of one species transferred their own specific antibiotic
resistance to bacteria of an entirely different species. Dr. Maurice Stroun
and Dr. Philip Anker in the Department of Plant Physiology at the University
of Geneva, began to accumulate evidence that the transfer of genetic
information is not confined to bacteria, but can also occur between bacteria
and higher plants and animals. According to an article in World Medicine on
September 22, 1971, "Geneva scientists are convinced that normal animal and
plant cells shed DNA, and that this DNA is taken up by other cells in the
organism."
In one experiment, scientists in Geneva extracted the auricles of frog
hearts and dipped them for several hours in a suspension of bacteria.
Afterward, they found a high percentage of RNA-DNA hybridization between
bacterial DNA extracted from bacteria of the same species as that used in
the experiment and titrated DNA extracted from the auricles which had been
dipped in the bacterial suspension. Bacterial DNA had been absorbed by the
animal cells. This phenomenon has been dubbed transcession. There is
evidence that this kind of phenomenon is happening all the time within the
human body. It is conceivable, for example, that heart damage following
rheumatic fever could the the result of the immune system reacting to its
own cells producing a foreign RNA complex after absorption of foreign DNA.
In Science magazine, November 10, 1972, bacterial RNA was demonstrated in
frog brain cells after a bacterial peritoneal infection. In the April 1973
issue of the Journal of Bacteriology, transcription of spontaneously
released bacterial DNA was found to be incorporated into cellular nuclei of
frog auricles. Studies by Phillipe Anker and Maurice Stroun have indicated
spontaneous release of DNA material from mammalian cells, spontaneous
transfer of DNA from bacteria to higher organisms, spontaneous transfer of
DNA between cells of higher organisms, release of RNA by mammalian cells,
and biological activity of released complexes containing RNA.
Malignant Cellular Transformations Caused By Foreign DNA:
There is evidence that freely circulating foreign DNA can cause malignancy.
In a 1977 issue of International Review of Cytology, Volume 51, Anker and
Stroun discuss the possible effects of foreign DNA causing malignant cell
transformations. When foreign DNA is transcribed into a cell of a different
organism, "this general biological event is related to the uptake by cells
of spontaneously released bacterial DNA, thus suggesting the existence of
circulating DNA. In view of the malignant transformations obtained with DNA,
the oncogenic (cancer-causing) role of circulating DNA is postulated."
The discovery in 1975 that viruses causing cancer in animals had a special
enzyme called reverse transcriptase makes the problem even more interesting.
These kind of viruses are called RNA viruses. When an RNA virus has the
reverse transcriptase enzyme within its structure, it allows the virus to
actually form strands of DNA which easily integrate with the DNA of the
host cell which it infects. Studies by Dr. Robert Simpson of Rutgers
University indicate that RNA viruses which do not cause cancer can also form
DNA, even without the presence of reverse transcriptase. DNA formed in this
way from an RNA virus is called a provirus. It is known that some
non-cancerous viruses have a tendency to exist as proviruses for long
periods of time in cells without causing any apparent disease. In other
words, they remain latent. Some examples of common RNA viruses that do not
cause cancer, per se, but have the capacity to form proviruses are
influenza, measles, mumps and polio viruses. In the October 22, 1967 British
Medical Journal, it was brought out by German scientists that multiple
sclerosis seemed to be provoked by vaccinations against smallpox, typhoid,
tetanus, polio, tuberculosis and diptheria. Even earlier, in 1965,
Zintchenko reported 12 cases in which MS became evident after a course of
anti-rabies vaccinations.
Remember that millions of people between 1950 and 1970 were injected with
polio vaccines containing simian virus 40 (SV-40) transferred from
contaminated monkey kidney cells used to culture the vaccine. It is
impossible to remove animal viruses from vaccine cultures. You are reminded
that SV-40, the 40th virus to be discovered in simian tissue, is a
cancer-causing virus.
Immunization programs against influenza, measles, mumps and polio are in
fact seeding humans with RNA and forming proviruses which become latent for
long periods in throughout the body, only to re-awaken later on.
Post-polio syndrome is a good example of this problem. Other examples may
include the so-called mesenchymal and collegen diseases, such as rheumatoid
arthritis, multiple sclerosis and lupus erythmatosis, where antibodies are
formed by the immune system against the person's own tissues - tissues which
have been impregnated with foreign genetic material. According to a special
issue of Postgraduate Medicine in May 1962, "although the body generally
will not make antibodies against its own tissues, it appears that slight
modification of the antigenic character of tissues may cause it to appear
foreign to the immune system and thus a fair target for antibody
production." Two years later in 1964, studies were conducted on the polyoma
virus, a tumor-producing DNA virus. It was discovered that the persistent
genetic DNA material in the polyoma virus brought about malignant
transformations in hamster embryo cell cultures. This was reported in the
November 23, 1964 issue of the Journal of the American Medical Association.
Even common non-tumor viruses, including those in smallpox vaccine and polio
virus 2, can act as carcinogens. It was reported in Science on December 15,
1961 that these common viruses acted as catalysts in producing cancer when
given to mice in combination with known organic carcinogens in amounts too
small to induce tumors themselves. This means that some vaccinations will
induce cancer, when combined with the growing problem of environmental
pollution from toxic by-products of agriculture (pesticides on and in food)
and industry. Of course, this information is hidden from the public, which
is why the FDA, EPA and the agricultural industries can get away with
"sanctioning" small amounts of pollutants in food, water and air. The
connection has not been made public, much to the joy of the chemical
industry, the National Cancer Institute and the growing cancer industry,
which continues to fraudulently solicit public donations to justify its own
existence. As an aside, it has already been admitted that polio
vaccinations have caused 100% of all polio in the United States since 1980
and the predominant cases of all paralytic polio since 1972 (Science, April
4, 1977). It is suspected that the Salk and Sabin vaccines, made of monkey
tissue culture, have also been responsible for the major increase in
leukemia in the United States.
The use of viruses, bacteria and animal tissue cultures in mass immunization
campaigns, considering that this information has been known for 20 years,
constitutes an intentionally created hazard to humans. The global impact on
the wide range of genotypes relative to human beings is difficult to
assess, but the outcome is definitely negative, and permitting the seeding
of latent proviruses in humans, knowingly, can have no other rationale other
than future medical profiteering, and constitutes a criminal conspiracy of
vast proportions which is tatamount to a genocidal policy against the
population, further constituting crimes against humanity, which is
internationally punishable by death. But, of course, especially in the
United States, this fact is ignored and suppressed from public knowledge,
despite a 1984 plea by some U.S. physicians to the United Nations in a
report. The fact that this goes on with the full knowledge of the world
medical community makes this an international conspiracy where the
population has no recourse, given that vaccinations are becoming mandatory
and a prerequisite for many social programs.
Persistence of long-term viruses and foreign proteins and their
relationship to chronic and degenerative disease was also pointed out by
Dr. Robert Simpson of Rutgers University in 1976, when he addressed science
writers at an American Cancer Society seminar, saying "these proviruses
could be molecules in search of a disease." Dr. Wendell Winters, a
virologist at the University of California noted, "immunizations may cause
changes in slow viruses and changes in the DNA mechanism." Although host
cells containing latent viral particles operate more or less normally, they
begin to synthesize viral proteins under the guidance of the viral DNA,
eventually creating the circumstances for various autoimmune diseases,
including diseases of the central nervous system, which unfortunately add to
the growing load of aberrant social behavior patterns.

Rett syndrome phenotype following infantile acute
encephalopathy.

Department of Pediatrics, University of Catania, Italy.
Rett syndrome is a progressive neurodevelopmental disorder with a
well-defined clinical spectrum and course. Recently, mutations in the gene
encoding X-linked methyl-CpG binding protein 2 (MECP2) have been identified
as the cause of Rett syndrome. Along with the classic form, variant forms of
Rett syndrome and Rett syndrome phenotypes are also recognized. We report on
a girl who, at age 2 months, developed an acute encephalopathy with
destructive brain damage 12 hours after acellular pertussis vaccination.
Peripheral lymphocyte subset analysis revealed the existence of T
lymphocytes double positive for CD4 and CD8 markers. This pattern normalized
over the following 3 months. Months later, the girl manifested a Rett
syndrome phenotype. DNA screening of the MECP2 gene was unrevealing in the
child and her parents. This previously unreported association emphasizes the
notion that Rett syndrome phenotypes can result from different (either
genetic or environmental) causes.

'Junk' throws up precious secret - DNA segments not
coding for proteins shared by many animals including humans
What do you know.....it might not be junk??????
Fools
Sheri
'Junk' throws up precious secret
By Julianna Kettlewell
BBC News Online science staff
A collection of mystery DNA segments, which seem to be critical for the
survival of many animals, are causing great interest among scientists.
Researchers inspecting the genetic code of rats, mice and humans were
surprised to find they shared many identical chunks of apparently "junk"
DNA.
This implies the code is so vital that even 75 million years of evolution
in these mammals could not tinker with it. But what the DNA does, and
how, is a puzzle, the journal Science reports.
Excess baggage?
Before scientists began laboriously mapping several animal life-codes,
they had a rather narrow opinion about which parts of the genome were
important. According to the traditional viewpoint, the really crucial
things were genes, which code for proteins - the "building blocks of
life". A few other sections that regulate gene function were also
considered useful.
It absolutely knocked me off my chair
David Haussler, University of California
The rest was thought to be excess baggage - or "junk" DNA. But the new
findings suggest this interpretation was somewhat wanting.
David Haussler of the University of California, Santa Cruz, US, and his
team compared the genome sequences of man, mouse and rat. They found - to
their astonishment - that several great stretches of DNA were identical
across the three species.
To guard against this happening by coincidence, they looked for sequences
that were at least 200 base-pairs (the molecules that make up DNA) in
length. Statistically, a sequence of this length would almost never
appear in all three by chance.
Not only did one sequence of this length appear in all three - 480 did.
Vital function
The regions largely matched up with chicken, dog and fish sequences, too;
but are absent from sea squirt and fruit flies. "It absolutely knocked me
off my chair," said Professor Haussler. "It's extraordinarily exciting to
think that there are these ultra-conserved elements that weren't noticed
by the scientific community before."
DNA: THE CODE OF LIFE
The double-stranded DNA molecule is held together by chemical components
called bases
Adenine (A) bonds with thymine (T); cytosine (C) bonds with guanine (G)
These letters form the "code of life"; there are close to 3 billion base
pairs in mammals such as humans and rodents Written in the DNA of these
animals are 25,000-30,000 genes which cells use as templates to start the
production of proteins; these sophisticated molecules build and maintain
the body
The really interesting thing is that many of these "ultra-conserved"
regions do not appear to code for protein. If it was not for the fact
that they popped up in so many different species, they might have been
dismissed as useless "padding". But whatever their function is, it is
clearly of great importance. We know this because ever since rodents,
humans, chickens and fish shared an ancestor - about 400 million years
ago - these sequences have resisted change. This strongly suggests that
any alteration would have damaged the animals' ability to survive.
"These initial findings tell us quite a lot of the genome was doing
something important other than coding for proteins," Professor Haussler
said. He thinks the most likely scenario is that they control the
activity of indispensable genes and embryo development. Nearly a quarter
of the sequences overlap with genes and may help slice RNA - the chemical
cousin of DNA involved in protein production - into different forms,
Professor Haussler believes. The conserved elements that do not actually
overlap with genes tend to cluster next to genes that play a role in
embryonic development.
"The fact that the conserved elements are hanging around the most
important development genes, suggests they have some role in regulating
the process of development and differentiation," said Professor Haussler.
Rethinking "junk" DNA
The next step is to pin down a conclusive function for these chunks of
genetic material. One method could be to produce genetically engineered
mice that have bits of the sequences "knocked out". By comparing their
development with that of normal mice, scientists might be able to work
out the DNA's purpose. Despite all the questions that this research has
raised, one thing is clear: scientists need to review their ideas about
junk DNA.
Professor Chris Ponting, from the UK Medical Research Council's
Functional Genetics Unit, told BBC News Online: "Amazingly, there were
calls from some sections to only map the bits of genome that coded for
protein - mapping the rest was thought to be a waste of time.
"It is very lucky that entire genomes were mapped, as this work is
showing." He added: "I think other bits of 'junk' DNA will turn out not
to be junk. I think this is the tip of the iceberg, and that there will
be many more similar findings." Humans and rats share large amounts of
DNA

Chemo More Dangerous Than Thought for Kids
THURSDAY, July 1 (HealthDayNews) -- Children with acute lymphocytic
leukemia (ALL) who suffer genetic damage caused by chemotherapy may
face an increased risk of further cancers and other diseases later in
life. That bad news comes from a University of Vermont Medical School
study published in the July 1 issue of Cancer Research.
The study found 45 children who received chemotherapy and survived their
disease had a 200-fold increase in the frequency of somatic mutations in
their DNA. These genetic changes remain embedded in the children's DNA.
"The therapies used to assist these children overcome ALL have the
potential to cause genetic damage to many different cell populations in
their rapidly growing bodies," Dr. Barry A. Finette, an associate
professor of pediatrics, said in a prepared statement.
"Because they have larger numbers of replicating cell populations during
their growth and development stages than adults have, they are more
susceptible than adults to the effects of the chemotherapies'
genotoxicity," Finette said. ALL is the most common malignant cancer in
children. Since the 1960s, the five-year survival rate in the United
States for children with ALL has increased to nearly 80 percent, thanks
to development of national standardized chemotherapy treatment
guidelines.
"Because of the effectiveness of the treatment employed today, we are
able to give many more children a chance for a long life without cancer,"
Finette said. "Our studies are aimed at enabling us to better understand
further challenges that we may face in keeping these patients health as
they get 10, 15, or more years out from overcoming ALL," he said.

The ahthors present new data on the character of the vaccine process in

and Rh systems. The greater frequency of occurrence and more manifest
reactions were noted in children with blood groups A, B, AB, M and Rho
(D) - in comparison with those having blood groups O, Rho (D) +, MN and
N. There was a significant prevalence of chromosomal aberrations in the
primarily immunized children with blood groups A in comparison with
groups O, B and AB. The data obtained pointed to the negative effect of
the mimi-rating antigens of the smallpox virus on the immunogenesis in
smallpox. Search for methods of releasing the vaccine of these antigens
is necessary for reduction of the reactogenic properties and increase of
immunogenecity of the smallpox vaccines.

intervals resulted in increased frequency of chromosomal aberrations in
bone marrow cells of the animals after the completion of the entire
vaccination course (14 and 30 days after the last vaccination). Measles

Vaccinations and Immunity
By Patrick Quanten MD
EXCERPTS:
Dr. Urnovitz and his colleagues have been studying the implications of
vaccines in cancer, Persian Gulf War Syndrome, multiple sclerosis, and AIDS.
Urnovitz, who holds doctorates in Immunology and Microbiology from the
University of Michigan where he studied vaccines, has become one of the most
vocal proponents for scientists to become aware of vaccine-associated
genetic mutations. His work in this area has supported the concepts that:
Our bodies have a “genetic memory” of foreign substances it encounters,
including vaccines. There is a limit on how much foreign material our bodies
can handle before genetic damage occurs and/or progresses into a chronic
illness. Each person has their own unique genetic blueprint which responds
to foreign substances differently. In a larger sense, the question about
possible effects of vaccines in causing adverse genetic changes might be
considered as the “black hole” of scientific knowledge. Even if it is taking
place, do we have the technology to identify it, and if not, do we have the
time to await the slow processes of science to prove such a relationship?
Studies from Africa, England, Sweden, and New Zealand have consistently
shown a greater incidence of allergic problems such as asthma and eczema,
along with increasing patterns of sickness, among fully vaccinated children
as compared to those with limited or no vaccines.
Some conclusions can already be drawn:
Vaccinations lower the immune response by weakening the outer defense
system. Increasing the toxic load so dramatically in the inner
workings of the immune system may be responsible for the surge in
auto-immune diseases we are seeing. The increased toxic load is responsible
for genetic modifications of the cells, leading to serious illnesses for
which modern science is hoping to find "gene-cures". Vaccination
of children with nutritional deficiencies (more likely in bottle-fed babies)
will lead to serious damage to the chromosomes. We are all unique in
our response to foreign substances such as vaccines and general use of these
techniques will inevitably lead to individuals being damaged.

Certainly the disease (smallpox) has diminished. But the plague, the "Black
Death", cholera, the bubonic plague, yellow fever and numerous other
epidemic pests which until recently occasionally decimated entire nations
have also diminished and, in fact, nearly disappeared. Not one of these
epidemics was treated by vaccination. Why, then, did they abate and
practically disappear? The answer is, because of the more general adoption
of soap, bathtubs, all kinds of sanitary measures, such as plumbing,
drainage and ventilation, and because of more hygienic modes of living.

Thimerosal induces micronuclei in the cytochalasin B
block micronucleus test with human lymphocytes
http://www.springerlink.com/content/mdhj0yg2fpp1wnav

Abstract
Thimerosal is a widely used preservative in
health care products, especially in vaccines. Due to possible
adverse health effects, investigations on its metabolism and
toxicity are urgently needed. An in vivo study on chronic toxicity
of thimerosal in rats was inconclusive and reports on genotoxic
effects in various in vitro systems were contradictory. Therefore,
we reinvestigated thimerosal in the cytochalasin B block
micronucleus test. Glutathione S-transferases were proposed to be
involved in the detoxification of thimerosal or its decomposition
products. Since the outcome of genotoxicity studies can be dependent
on the metabolic competence of the cells used, we were additionally
interested whether polymorphisms of glutathione S-transferases
(GSTM1, GSTT1, or GSTP1) may influence the results of the
micronucleus test with primary human lymphocytes. Blood samples of
six healthy donors of different glutathione S-transferase genotypes
were included in the study. At least two independent experiments
were performed for each blood donor. Significant induction of
micronuclei was seen at concentrations between 0.05-0.5 µg/ml in 14
out of 16 experiments. Thus, genotoxic effects were seen even at
concentrations which can occur at the injection site. Toxicity and
toxicity-related elevation of micronuclei was seen at and above 0.6
µg/ml thimerosal. Marked individual and intraindividual variations
in the in vitro response to thimerosal among the different blood
donors occurred. However, there was no association observed with any
of the glutathione S-transferase polymorphism investigated. In
conclusion, thimerosal is genotoxic in the cytochalasin B block
micronucleus test with human lymphocytes. These data raise some
concern on the widespread use of thimerosal.
Genotoxic
chemicals are those which are capable of causing damage to DNA. Such
damage can potentially lead to the formation of a malignant tumor, but
DNA damage does not lead inevitably to the creation of cancerous cells

DNA study challenges basic ideas in genetics
Genome 'junk' appears essential
By Colin Nickerson, Globe Staff | June 14, 2007
A massive international study of the human genome has caused scientists to
rethink some of the most basic concepts of cellular function. Genes, it
turns
out, may be relatively minor players in genetic processes that are far more
subtle and complicated than previously imagined. Among the critical
findings: A huge amount of DNA long regarded as useless -- and dismissively
labeled "junk DNA" -- now appears to be essential to the regulatory
processes that control cells. Also, the regions of DNA lying between genes
may be powerful triggers for diseases -- and may hold the key for potential
cures.
The research, published in a set of papers in today's editions of the
journals Nature and Genome Research, raised far more questions than it
answered --
and in a sense was a rallying cry for more and deeper research into the
functioning of the genome, often referred to as the "blueprint" for life.
"The instruction manual for life is written in a language we are only just
beginning to understand," Francis Collins, director of the federal
government's National Human Genome Research Institute , said at a news
conference yesterday. Collins' s institute was among the more than 80
research institutions in North America, Europe, Asia, and Australia that
participated in the $42 million, four-year study, whose aim was to analyze
30 million units of human DNA -- just 1 percent of the entire human genome
-- to create an inventory of biologically functional elements. The project
is known as the Encyclopedia of DNA
Elements, or ENCODE, and involved an exhaustive scrutiny of 44 broad "sites"
in the human genome, probing not just genes, but all material in the
samples.
"We're finding that a lot of the genome is as mysterious as 'dark matter' in
physics; we know it is out there doing something. The challenge is to find
out
what and why," said Thomas D. Tullius , professor of chemistry at Boston
University and one of the ENCODE researchers. "There were huge surprises;
this research has upset a lot of thinking about how the genome works." He
added in an interview: "There now appear to be thousands of places in the
genome that were long thought to be useless or meaningless, but which we now
see to have a functional role. But we don't really understand what that role
is."
Most startling, according to researchers, is that some areas of the genome
looming as crucial are regions that don't contain specific instructions for
making proteins. That recognition amounts to a sea change in basic biology.
There are about 20,000 genes in the human body. But they are surrounded by
other DNA material whose exact purpose is unclear. Roughly 1 percent of the
human genome is thought to be "protein-coding" -- that is, genes. Another 4
percent had been thought to be "non coding DNA" that serves as on-off
switches for the genes, and the rest was seen as a sort of swamp with no
clear purpose.
But the new work suggests that the "control regions" in the DNA are far more
extensive, perhaps embracing more than half of all DNA. Functions thought to
be carried out by genes alone now appear to be managed by multiple,
overlapping segments of DNA. In addition, other portions of the genome are
believed to be on standby, as a toolbag to be utilized as humans evolve.
"It's like clutter in the attic," said Collins. "Most of the time, the human
genome is operating on the 'first and second floor,' with 5 percent of the
genome doing what needs to be done on a daily basis. But over evolutionary
time, a much larger part of the genome, the stuff in the attic, becomes
important. It's waiting for natural selection to call for it."
The ENCODE research builds on the historic Human Genome Project, largely
completed in 2003, which cataloged the genes. Instead of the "big picture"
look at the entire structure, the ENCODE project fine-combed selected sites
in the genome in extraordinary detail. Half the sites were known by
scientists to affect gene replication and protein coding; the other half
were random samples from across the genome, including swatches of "junk."
A long standing assumption in genetics has been that cellular organisms are
run by genes, which instruct cells to produce proteins thought to be the
main
driving mechanism in cells. But according to the study, obscure sections of
the genome, the "junk DNA," may play an even more critical role in health
and
evolution than genes themselves.
"We're reshaping our understanding of which regions of the genome produce
the critical information" that allows organisms to function and evolve, said
Michael Snyder, professor of molecular biophysics at Yale University and one
of
the researchers.
Recent research into heart attacks and diabetes has made the startling
discovery that the roots of disease may lie in noncoding portions of DNA,
not in the genes themselves.
In a significant finding, researchers discovered that "gene transcription"
-- essential to the process by which DNA builds proteins indispensable to
life
-- is occurring in regions between genes. They found that ribonucleic acid,
or RNA, long seen as another type of genetic code that directs cellular
machinery to make proteins, is also produced in stretches of the genome not
involved in protein production. That suggests that these regions have an
important purpose, though still not understood, the scientists said.
"Transcription appears to be far more interconnected across the genome than
anyone had thought," said Collins, adding that the ENCODE findings are
"moving us into a deeper understanding of how life works and how, sometimes,
things go wrong and disease occurs."
But untangling the tantalizing implications of the new findings will be the
work of years.
"It's like reading a code, text jumbled together, and you're trying to make
sense of it," said Zhiping Weng, professor of biomedical engineering at
Boston University and a researcher in the study. "This project provides many
new insights into the complex functional landscape of the human genome."©

# 15 Toxic Exposure Can Be Transmitted to
Future Generations on a “Second Genetic Code”
Source: Rachel’s Democracy & Health News, October 12, 2006
Title: “Some Chemicals are More Harmful Than Anyone Ever Suspected”
Author: Peter Montague
http://www.precaution.org/lib/06/ht061012.htm
Student Researchers: Kristen Kebler and Michael Januleski
Faculty Evaluator: Gary Evans, M.D.
Research suggests that, contrary to previous belief, our behavior and our
environmental conditions may program sections of our children’s DNA. New
evidence about how genes interact with the environment suggests that many
industrial chemicals may be more ominously dangerous than previously
thought. It is increasingly clear that the effects of toxic exposure may be
passed on through generations, in ways that are still not fully understood.
“This introduces the concept of responsibility into genetics and
inheritance,” said Dr. Moshe Szyf, a researcher at McGill University in
Montreal, “This may revolutionize medicine. You aren’t eating and exercising
just for yourself, but for your lineage.”1 The new field of genetic
research, called epigenetics, involves what scientists are referring to as a
“second genetic code” which influences how genes act in the body. If DNA is
the hardware of inheritance, the epigenetic system is the software. The
epigenetic system determines which genes get turned “off” or “on” and how
much of a certain protein they produce. It is this switching system that
allows the genetic material in each cell to influence the creation of
proteins—which ones are manufactured, in what sequence, and how many.
Proteins are the building blocks of our bodies. The chemicals and hormones
in our bodies are proteins. They determine, in large part, how we look, how
we feel, even how we act.1 Now, it seems that this chemical switching system
may also act in reverse. In most cases, epigenetic changes (changes to DNA
from current environmental conditions) are not passed from parents to their
offspring. Scientists are still not sure how—but genes seem to be “wiped
clean” after a sperm fertilizes an egg. Based on the recent data, however,
researchers are intrigued by the notion that some of the genetic changes
influenced by our diet, our behaviors, or our environment, may be passed on
from generation to generation.
On average, 1,800 new chemicals are registered with the federal government
each year and about 750 of these find their way into products, all with
hardly any testing for health or environmental effects. The bad news about
chemical contamination is steadily mounting, while the number of new
chemicals is steadily increasing. Many critics of the chemical and
pharmaceutical industries are renewing their admonitions that government
agencies practice the “precautionary principle”—the rule of “do no harm
first” in the approval of new drugs and chemicals. In 2005, the European
Union responded to this situation by trying to enact a new law called
Registration, Evaluation and Authorization of Chemicals (REACH), which
requires that chemicals be tested before they are sold—not after. As they
say in Europe, “No data, no market.” At the same time, US and European
chemical industries—and the White House—began working overtime to subvert
the European effort to enact REACH. Their efforts failed, however, and the
REACH act was adopted by the European Union in December, 2006.2 Chemical
companies throughout the US and Europe are still struggling with how they
will respond to the new requirements.

UPDATE BY PETER MONTAGUE
Basically this story tells us that environmental influences (like our
mother’s diet and her exposure to toxic chemicals) are far more important to
us than anyone suspected just a decade ago. It turns out that environmental
influences shape us from the moment of conception onward, and the earliest
months and years of life are the most important ones. It is called “fetal
programming” and it means our first environment (the womb) can determine
what sorts of diseases will afflict us later in life. Furthermore, some of
these early influences can be inherited by our offspring and even by their
offspring. So your personal pattern of disease may have been set by your
grandmother’s diet, or by her exposure to toxicants.
These findings imply that keeping toxic industrial chemicals out of the
environment is far more urgent than anyone has previously thought. With more
than 1,000 chemicals presently entering commercial channels each year with
almost no health or safety testing, this is not welcome news. In May 2007, a
group of two hundred scientists from five continents issued strongly worded
consensus statement (the “Faroes Statement”) saying that early exposure to
common chemicals leaves babies more likely to develop serious diseases later
in life, including diabetes, attention deficits, certain cancers, thyroid
disorders, and obesity, among others.
Notably, the scientists urged governments not to wait for more scientific
certainty but to take precautionary action now to protect fetuses and
children from toxic exposures. Most of the mainstream press continued to
tiptoe around this story, with a few important exceptions, until May 2007
when the Faroes statement blew the story open. Now that it is out in the
open, we’ll have to see if the mainstream press has what it takes to explain
the far-reaching
ramifications of these findings. The best source of information on this
topic (and many others) is http://www.environmentalhealthnews.org. Search
for “epigenetics,” “fetal programming,” or “gene expression.”
