MANILA, Philippines Celebrity hairstylist Ricky Reyes, talent manager and host Lolit Solis, actress Lorna Tolentino and even former President Joseph Estrada are only among the prominent Filipinos who swear by the healing effects of fresh cell therapy, which involves the injection of live animal cells into the body.

Reyes, who used to suffer from a rare disease which he called reading eye epilepsy, said he went to Germany last June for fresh cell therapy.

After a number of sessions, the celebrity hairstylist can now read newspapers without suffering a seizure.

It was gone immediately, he said. Pati arthritis ko. Naalis yung sakit, tapos gaganda at babata ka pa.

Solis, 65, had fresh cell therapy after experiencing knee pain, and 75-year-old Estrada opted to undergo the procedure in Germany to keep healthy.

Before them, several other well-known figures worldwide are said to have tried fresh cell treatments, among them the late English actor Charlie Chaplin.

So how is this procedure done? Dr. Robert Janson-Muller, who runs a fresh cell therapy clinic in Germany, is in town to give Filipinos the lowdown on this decades-long treatment.

Not stem cell treatment

Before starting his lecture for members of the local media on Tuesday, Janson-Muller made it clear that fresh cell therapy is different from the now controversial stem cell treatment, which aims to replace damaged organs in the body or create one from scratch.

He stressed that his methods, which do not promise miracles, have been proven effective by his predecessors for the past 60 years.

August 13, 2012 (BRONX, NY) Scientists at Albert Einstein College of Medicine of Yeshiva University have made a discovery involving mice and humans that could mean that people with acute myeloid leukemia (AML), a rare and usually fatal cancer, are a step closer to new treatment options. Their study results were published online today in Cancer Cell.

"We have discovered that a gene called HLX is expressed at abnormally high levels in leukemia stem cells in a mouse model of AML," said Ulrich Steidl, M.D., Ph.D., assistant professor of cell biology and of medicine at Einstein and senior author of the paper. (Gene expression is the process by which a gene synthesizes the molecule that it codes for; an "over-expressed" gene makes its product in abnormally high amounts.)

According to the National Cancer Institute, AML will be diagnosed in one of every 254 people during their lifetime. Most die within a few years of diagnosis. For the last several decades there has been little improvement in the survival rate for AML patients.

Dr. Steidl and his colleagues found that over-expression of the HLX gene in mice caused blood-forming stem cells to become dysfunctional and develop into abnormal progenitors (biological ancestors) of white blood cells that failed to differentiate into normal blood cells. Instead, those early, abnormal white cells formed duplicates of themselves.

The researchers then analyzed HLX expression data collected from 354 AML patients and found that 87 percent of them were over-expressing HLX compared with HLX expression in healthy individuals. And among patients expressing HLX at high levels in an even larger cohort of 601 patients: the greater their degree of HLX expression, the worse their survival chances.

Importantly, when Dr. Steidl's team used a laboratory technique to "knock down" HLX expression in AML cells taken from a mouse model of AML and from AML patients, proliferation of leukemia cells was greatly suppressed in both cases. And when the researchers knocked down HLX expression in mouse AML cells and human AML cells and then transplanted both types of cancer cells into healthy mice, those mice lived significantly longer compared with mice that received unaltered AML cells.

These findings suggest that targeting elevated HLX expression may be a promising novel strategy for treating AML.

"HLX is clearly a key factor in causing the over-production of white cells that occurs in AML," said Dr. Steidl. "Our research is still in its early stages, but we're looking towards developing drugsso we can improve treatment for AML and possibly other types of cancer." Einstein has filed a patent application related to this research. The HLX technology is available for licensing.

Gene discovery could improve treatment for acute myeloid leukemia

ScienceDaily (Aug. 14, 2012) Two papers that will appear in the journal Molecular Psychiatry, both receiving advance online release, may help identify gene variants that contribute to the risks of developing obsessive-compulsive disorder (OCD) or Tourette syndrome (TS). Both multi-institutional studies were led by Massachusetts General Hospital (MGH) investigators, and both are the first genome-wide association studies (GWAS) in the largest groups of individuals affected by the conditions.

"Previous studies of these disorders have demonstrated that both TS and OCD are strongly heritable and may have shared genetic risk factors, but identification of specific genes has been a huge challenge," says Jeremiah Scharf, MD, PhD, of the Psychiatric and Neurodevelopmental Genetics Unit (PNGU) in the MGH Departments of Psychiatry and Neurology, a co-lead author of both papers and co-chair of the Tourette Syndrome Association International Consortium for Genetics. "These new studies represent major steps towards understanding the underlying genetic architecture of these disorders."

An anxiety disorder characterized by obsessions and compulsions that disrupt patients' lives, obsessive-compulsive disorder (OCD) is the fourth most common psychiatric illness. Tourette syndrome, a chronic disorder characterized by motor and vocal tics, usually begins in childhood and is often accompanied by conditions like OCD or attention-deficit hyperactivity disorder. Both conditions have a high risk of recurrence in close relatives of affected individuals, but previous studies that compared affected and unaffected individuals were not large enough to identify specific genes or areas of the genome that contribute to risk.

Since many gene variants probably contribute to risk for both conditions, the research teams undertook GWAS investigations, which analyze hundreds of thousands of gene variants called SNPs (single-nucleotide polymorphisms) in thousands of individuals with and without the condition of interest. The International OCD Foundation Genetic Collaborative, consisting of more than 20 research groups in nine countries, analyzed almost 480,000 SNPs in 1,465 individuals with OCD, more than 5,500 controls and from 400 trio samples consisting of an OCD patient and both parents. The Tourette Syndrome Association International Consortium for Genetics and the TS GWAS Consortium, representing 22 groups across seven countries, analyzed 484,000 SNPs across almost 1,500 cases and more than 5,200 controls.

The OCD study -- led by Evelyn Stewart, MD, of the MGH-PNGU, who is now based at the University of British Columbia, and David Pauls, PhD, MGH-PNGU -- identified possible associations close to a gene called BTBD3, which is closely related to a gene that may be involved in Tourette Syndrome, and within DLGAP1, a close relative of a gene that produces OCD-like symptoms in mice if it is deleted. The Tourette study was led by Scharf and Pauls and found evidence of a possible association with a gene called COL27A1, which may be expressed in the cerebellum during development, and with variants that help regulate gene expression in the frontal cortex.

None of these or other identified SNPs reached the high threshold of genome-wide significance, which would indicate that the associations represented true risk factors, and the authors stress that additional, larger studies are required. "Although GWAS analysis allows much more comprehensive examination of the entire genome than do studies focused on particular families or candidate genes, these two studies are still underpowered and should be interpreted with caution," says Pauls, a co-senior author of both papers. "The current results are interesting and provide us with a starting point for analyzing future studies that must be done to replicate and extend these findings."

Scharf adds that the next steps should include testing the SNPs identified by these studies in other groups of patients and controls, analyzing both study groups together to identify genes that contribute to the risk of both disorders, and expanding international collaborations to increase the size and power of patient samples for both OCD and TS. "If future studies confirm that some of these variants do contribute to risk -- either directly or by altering the function of other risk genes -- that would suggest both novel disease mechanisms and might give us new treatment targets," he says.

Quintiles Acquires Expression Analysis, Premier Provider of Genomics Services, to Advance Personalized Medicine

LOS ANGELES, Aug. 14, 2012 /PRNewswire/ -- Response Genetics, Inc. (RGDX), a company focused on the development and sale of molecular diagnostic tests for helping determine a patient's response to cancer therapy, today announced its consolidated financial results for the second quarter ended June 30, 2012.

Total revenues for the quarter ended June 30, 2012 were $3.84 million, compared to $3.98 million for the quarter ended March 31, 2012 and $6.70 million for the quarter ended June 30, 2011. The decrease relative to last year was largely a result of the expected decrease in pharmaceutical client revenue. The Company's ResponseDX revenue decreased slightly by $151 thousand and the pharmaceutical client revenue decreased by $2.72 million relative to the quarter ended June 30, 2011.

The Company's net loss for the quarter ended June 30, 2012 was $2.7 million compared to a net loss of $3.1 million for the quarter ended March 31, 2012 and a net loss of $0.1 million for the quarter ended June 30, 2011. This is the second consecutive quarter the Company decreased its net loss.

The Company also increased its gross margin in two consecutive quarters from approximately 25% for the fourth quarter of 2011, to approximately 32% for the quarter ended March 31, 2012 to approximately 37% for the quarter ended June 30, 2012. Gross margin is defined as net revenue less cost of revenue.

Excluding cost of revenue, total operating expenses for the second quarter were $4.1 million, compared to $4.4 million for the quarter ended March 31, 2012 and $4.0 million for the same period last year.

"We have made many changes in the Company since the beginning of the year and we believe we have made great strides, both financially and strategically. Since the fourth quarter of 2011, gross margins have increased, expenses have been reduced, and losses have subsequently decreased," said Thomas Bologna, the Company's Chairman & Chief Executive Officer. "Additionally, we expect our third quarter operating results to continue this favorable trend, and in fact, we believe the results will be better based on additional actions that we have taken since the end of the second quarter."

Mr. Bologna added, "We appreciate that we need to work the top line as well and as noted in our recent Form 8-K, we are pleased to have extended/replaced our existing Amended and Restated Master Services Agreement with GlaxoSmithKline Biologicals S.A. (GSK), which expired on May 15, 2012. The Second Amended and Restated Master Services Agreement enables us to continue to provide services to GSK for up to an additional two and a half years and to continue to derive revenues from those services. We are also pleased to report that we recently achieved a milestone under our existing Non-Exclusive License Agreement with GSK, dated March 10, 2010, which has resulted in us receiving a $500,000 milestone payment last week."

Total revenues for the six months ended June 30, 2012 were $7.8 million compared to $12.6 million for the six months ended June 30, 2011, the decrease largely a result of the expected decrease in pharmaceutical client revenue of $4.5 million from $6.5 million for the six months ended June 30, 2011 to $2.0 million for the six months ended June 30, 2012. The Company's ResponseDX revenue was $5.8 million for the six months ended June 30, 2012, compared to $6.1 million for the six months ended June 30, 2011.

The Company's net loss for the six months ended June 30, 2012 was $5.9 million, compared with a net loss of $0.4 million for the six months ended June 30, 2011.

Excluding cost of revenue, total operating expenses for the six months were $8.5 million, compared to $7.5 million for the same period last year. The increase in total operating expense of $1.0 million was due to an increase in general and administrative expenses of $0.1 million and an increase in research and development expenses of $0.9 million.

Gene mutation responsible of inherited ataxia found through sophisticated genetic analysis of Asian, European & American families

Newswise ANN ARBOR, Mich. A global hunt for the cause of a crippling inherited nerve disorder has found its target. The discovery opens the door for better diagnosis and treatment of this particular disease but also for better understanding of why nerves in the brains movement-controlling center die, and how new DNA-mapping techniques can find the causes of other diseases that run in families.

In a new paper in the Annals of Neurology, a team from Taiwan, France and the University of Michigan Health System report that mutations in the gene KCND3 were found in six families in Asia, Europe and the United States that have been haunted by the same form of a disease called spinocerebellar ataxia or SCA. The disease causes progressive loss of balance, muscle control and ability to walk.

The new paper finds the disease gene in a region of chromosome 1 where a Dutch group had previously shown linkage with a form of SCA called SCA19, and the Taiwanese group on the new paper had shown similar linkage in a family for a form of the disease that was then called SCA22.

The Dutch group has just published results in the same issue of the journal, zeroing in on the same gene as the U-M/Taiwanese/French groups.

The gene governs the production of a protein that allows nerve cells to talk to one another through the flow of potassium. Pinpointing its role as a cause of ataxia will now allow more people with ataxia to learn the exact cause of their disease, give a very specific target for new treatments, and perhaps allow the families to stop the disease from affecting future generations.

But the findings also have significance beyond ataxia. The researchers also show that when KCND3 is mutated, it causes not only poor communication between nerve cells in the cerebellum but also the death of those cells. Its information that could aid research on other neurological disorders involving balance and movement.

Margit Burmeister, Ph.D., the U-M geneticist who helped lead the work, notes that the gene could not have been found without a great deal of DNA detective work and the cooperation of the families who volunteered to let researchers map all the DNA of multiple members of their family tree.

We combined traditional genetic linkage analysis in families with inherited diseases with whole exome sequencing of an individuals DNA, allowing us to narrow down and ultimately identify the mutation, she says. This new type of approach has already resulted in many new gene identifications, and will bring in many more.

U-M neurologist Vikram Shakkottai, M.D., Ph.D., an ataxia specialist and co-author on the paper, notes that the new genetic information will help patients find out the specific cause of their disease a reassuring thing in itself.

New Rochelle, NY, August 13, 2012Even after being frozen for 18 years, human embryos can be thawed, grown in the laboratory, and successfully induced to produce human embryonic stem (ES) cells, which represent a valuable resource for drug screening and medical research. Prolonged embryonic cryopreservation as an alternative source of ES cells is the focus of an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc. The article is available free online at the BioResearch Open Access website.

Kamthorn Pruksananonda and coauthors from Chulalongkorn University and Chulalongkorn Memorial Hospital, Bangkok, Thailand, demonstrated that ES cells derived from frozen embryos have a similar ability to differentiate into multiple cell typesa characteristic known as pluripotencyas do ES cells derived from fresh embryos. They present their findings in the article "Eighteen-Year Cryopreservation Does Not Negatively Affect the Pluripotency of Human Embryos: Evidence from Embryonic Stem Cell Derivation."

"The importance of this study is that it identifies an alternative source for generating new embryonic stem lines, using embryos that have been in long-term storage," says Editor-in-Chief Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland.

Human embryos frozen for 18 years yield viable stem cells suitable for biomedical research

ScienceDaily (Aug. 10, 2012) Duke researchers may have found a promising stem cell therapy for preventing osteoarthritis after a joint injury.

Injuring a joint greatly raises the odds of getting a form of osteoarthritis called post-traumatic arthritis, or PTA. There are no therapies yet that modify or slow the progression of arthritis after injury.

Researchers at Duke University Health System have found a very promising therapeutic approach to PTA using a type of stem cell, called mesenchymal stem cells (MSCs), in mice with fractures that typically would lead to them developing arthritis. Their findings could lead to a therapy that would be used after joint injury and before signs of significant osteoarthritis.

The scientists thought the stem cells would work to prevent PTA by altering the balance of inflammation and regeneration in knee joints, because these stem cells have beneficial properties in other regions of the body.

"The stem cells were able to prevent post-traumatic arthritis," said Farshid Guilak, Ph.D., director of orthopaedic research at Duke and senior author of the study.

The study was published on August 10 in Cell Transplantation.

The researchers also thought that a type of mice bred for their super-healing properties would probably fare better than typical mice, but they were wrong.

"We decided to investigate two therapies for the study, said lead author Brian Diekman, Ph.D., a postdoctoral researcher in the Guilak lab. "We thought that stem cells from so-called superhealer mice would be superior at providing protection, and instead, we found that they were no better than stem cells from typical mice. We thought that maybe it would take stem cells from superhealers to gain an effect as strong as preventing arthritis after a fracture, but we were surprised -- and excited -- to learn that regular stem cells work just as well."

Certain people appear to fall into the superhealer category, too. They bounce back quickly and heal well naturally after a fracture, while other people eventually form cases of arthritis at the fractured joint, said Guilak, who is a professor of orthopaedic surgery and biomedical engineering.

"The ability of the superhealer mice to have superior healing after a fracture may go beyond the properties of their stem cells and be some beneficial factor, like a growth factor, that we don't know about yet," Guilak said.

Stem cells may prevent post-injury arthritis

ScienceDaily (Aug. 12, 2012) Genetics researchers have identified a key gene that, when mutated, causes the rare multisystem disorder Cornelia deLange syndrome (CdLS). By revealing how mutations in the HDAC8 gene disrupt the biology of proteins that control both gene expression and cell division, the research sheds light on this disease, which causes intellectual disability, limb deformations and other disabilities resulting from impairments in early development.

"As we better understand how CdLS operates at the level of cell biology, we will be better able to define strategies for devising treatments for CdLS, and possibly for related disorders," said study leader Matthew A. Deardorff, M.D., Ph.D., a pediatric genetics clinician and scientist at The Children's Hospital of Philadelphia. Deardorff also is in the Perelman School of Medicine at the University of Pennsylvania.

Deardorff and co-corresponding author Katsuhiko Shirahige, Ph.D., of the Research Center for Epigenetic Disease at the University of Tokyo, published their study online August 12 in Nature.

The current findings add to previous discoveries by researchers at The Children's Hospital of Philadelphia. A group led by Ian Krantz, M.D., and Laird Jackson, M.D., announced in 2004 that mutations in the NIPBL gene are the primary cause of CdLS, accounting for roughly 60 percent of the "classical" cases of the disease. In 2007, Deardorff joined them to describe mutations in two additional genes, SMC1A and SMC3. First described in 1933, CdLS affects an estimated 1 in 10,000 children.

The CdLS research team at Children's Hospital has focused on the cohesin complex, a group of proteins that form a bracelet-like structure that encircles pairs of chromosomes, called sister chromatids. "Cohesin has two roles," said Deardorff. "It keeps sister chromatids together during cell division, and it allows normal transcription -- the transmission of information from DNA to RNA."

Deardorff added that mutations that perturb normal cohesin function can interfere with normal human development. Such is the case in CdLS, which exemplifies a newly recognized class of diseases called cohesinopathies.

In the current study, the scientists investigated both acetylation -- how an acetyl molecule is attached to part of the cohesin complex -- and deactylation, the removal of that molecule. Normally, deactylation helps recycle cohesin to make it available during successive rounds of cell division. The study team found that mutations in the HDAC8 gene threw off normal cellular recycling of cohesin.

Mutations in the gene cause loss of HDAC8 protein activity, and consequently decrease the amount of "recharged" cohesin available to properly regulate gene transcription. This, in turn, the researchers suggest, impairs normal embryonic development and gives rise to CdLS.

The researchers showed in cell cultures that mutations in HDAC8 lead to a decrease in cohesin binding to genes, similar to that seen for cells deficient in the NIPBL gene. They also identified HDAC8 mutations in approximately 5 percent of patients with CdLS.

Because mothers of children with CdLS may carry mutations in the HDAC8 gene, identifying these mutations will be very useful in accurately counseling families of their recurrence risk -- the likelihood of having a subsequent child with CdLS.

FORMER Superman star Christopher Reeve would be proud to know he inspired remarkable advances in spinal cord injury research, the late actor's son says.

Matthew Reeve, who is in Australia promoting his father's work towards finding a cure for paralysis, said the Superman legacy lives on through the Christopher and Dana Reeve Foundation, which funds research and advocates the wellbeing of people with spinal cord injuries.

"I think he would be extremely proud," he told reporters in Sydney today.

"When he became paralysed, spinal cord research was fragmented, uncentralised and uncoordinated.

Superman's son says legacy lives on

Former Superman star Christopher Reeve would be proud to know he inspired remarkable advances in spinal cord injury research, the late actor's son says.

Matthew Reeve, who is in Australia promoting his father's work towards finding a cure for paralysis, said the Superman legacy lives on through the Christopher and Dana Reeve Foundation, which funds research and advocates the wellbeing of people with spinal cord injuries.

"I think he would be extremely proud," he told reporters in Sydney on Monday.

"When he became paralysed, spinal cord research was fragmented, uncentralised and uncoordinated.

"He embraced the role of being champion to that, and under his beacon of leadership, we've united researchers and we've seen some remarkable changes."

ScienceDaily (Aug. 10, 2012) Duke researchers may have found a promising stem cell therapy for preventing osteoarthritis after a joint injury.

Injuring a joint greatly raises the odds of getting a form of osteoarthritis called post-traumatic arthritis, or PTA. There are no therapies yet that modify or slow the progression of arthritis after injury.

Researchers at Duke University Health System have found a very promising therapeutic approach to PTA using a type of stem cell, called mesenchymal stem cells (MSCs), in mice with fractures that typically would lead to them developing arthritis. Their findings could lead to a therapy that would be used after joint injury and before signs of significant osteoarthritis.

The scientists thought the stem cells would work to prevent PTA by altering the balance of inflammation and regeneration in knee joints, because these stem cells have beneficial properties in other regions of the body.

"The stem cells were able to prevent post-traumatic arthritis," said Farshid Guilak, Ph.D., director of orthopaedic research at Duke and senior author of the study.

The study was published on August 10 in Cell Transplantation.

The researchers also thought that a type of mice bred for their super-healing properties would probably fare better than typical mice, but they were wrong.

"We decided to investigate two therapies for the study, said lead author Brian Diekman, Ph.D., a postdoctoral researcher in the Guilak lab. "We thought that stem cells from so-called superhealer mice would be superior at providing protection, and instead, we found that they were no better than stem cells from typical mice. We thought that maybe it would take stem cells from superhealers to gain an effect as strong as preventing arthritis after a fracture, but we were surprised -- and excited -- to learn that regular stem cells work just as well."

Certain people appear to fall into the superhealer category, too. They bounce back quickly and heal well naturally after a fracture, while other people eventually form cases of arthritis at the fractured joint, said Guilak, who is a professor of orthopaedic surgery and biomedical engineering.

"The ability of the superhealer mice to have superior healing after a fracture may go beyond the properties of their stem cells and be some beneficial factor, like a growth factor, that we don't know about yet," Guilak said.

South Korea - A local team of scientists has discovered genes closely involved in regulating feeding behaviour, opening new possibilities for treating obesity and metabolic disorders.

Led by Yu Kweon, principal researcher at Korea Research Institute of Bioscience and Biotechnology's Aging Research Center, the team found that the fruit fly gene minibrain, or mnb, and mammalian functional equivalent DYRK1a gene control the expression of neuropeptides - proteins that transmit signals from nerve cells - involved in food intake regulation.

The results were published in the August issue of the peer-review journal PLoS Genetics.

In fruit flies, the mnb gene controls the expression of short neuropeptide F, or sNPF, while DYRK1a controls that of neuropeptide Y, or NPY.

Yu's research showed that the fruit fly and mammalian genes stimulate the production of the relevant proteins.

In the experiments, fruit flies with artificially enhanced mnb gene expression had 60 per cent larger daily food intake than control insects. In contrast, the food intake of flies with reduced mnb gene expression was about 30 per cent lower than those with normal levels of gene expression.

Similar results were also obtained in mice, with subjects with enhanced DYRK1a gene expression eating 20 per cent more.

In addition, Yu found that while DYRK1a acts in a positive feedback loop where NPY expression is increased with the rise in DYRK1a expression, the same process is dampened by insulin, the lack of which is the cause of Type 1 diabetes.

Although the involvement of sNPF and neuropeptide Y in food intake control has been known for some time, Yu and his team were the first to discover that the food intake-related genes are controlled by other genes.

BAR HARBOR Advances in genetic medicine are proceeding at such a rapid clip that solutions to some of humanitys most intractable medical problems could be present within the decade, Jackson Laboratory President and CEO Edison Liu, M.D. said Monday. Dr. Liu was speaking before a crowd of 150 gathered at the Bar Harbor Club for the annual meeting of the Mount Desert Island Hospital.

If we can push the envelope, we will cure cancer by the year 2020, Dr. Liu said in his keynote address. If Jackson Lab, on the little island on MDI, can win the Nobel Prize, we can beat breast cancer.

Advances in technology and in knowledge of the human genome have risen so much in the past decade that what we imagined just a few years ago is now reality, Dr. Liu said.

Today, we have high-resolution understanding of your genetics and your genome. We dont have to guess anymore, he said. We havent seen anything like this since the development of the motherboard in electronics.

In typical cancer treatment, a 30 percent response rate is considered a good outcome. But, with the growing ability to tailor drugs to each individual, the field of personalized medicine now promises the ability to increase that rate greatly, if not eliminate mortality from the disease altogether.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY, I'm Ira Flatow. Earlier this week, yet another potential cure for Alzheimer's failed. Pfizer called off additional studies of its intravenous drug bapineuzumab, an antibody designed to seek and destroy plaques that build up in the brains of people with Alzheimer's.

The thinking was that if you clear the plaques, maybe the dementia will improve or go away. Unfortunately, the drug did not seem to do that. But it's not the only possibility. Researchers are testing other types of antibodies. They're testing hormones. They're trying gene therapy. What are the chances that these approaches will pan out? Might we see an Alzheimer's vaccine someday? That's what we're going to be talking about, a status check on Alzheimer's research.

Our number is 1-800-989-8255. You can tweet us @scifri, and you can also go to our website at sciencefriday.com.

Dr. Ronald Petersen is director of the Mayo Alzheimer's Disease Research Center at the Mayo Clinic in Rochester, Minnesota. Welcome to SCIENCE FRIDAY, Dr. Petersen.

RONALD PETERSEN: Thanks very much, Ira.

FLATOW: First give us a little inside baseball on what happened with the Pfizer drug. Did it not clear the plaques? Do we know? Do we know why it failed?

PETERSEN: Well, it was a preliminary report regarding the clinical findings, meaning that the memory, the functional changes in these patients with the mild to moderate state of the dementia of Alzheimer's disease, the clinical features did not improve.

What we don't know yet, they haven't announced yet, is whether the drug actually had an impact on the underlying biological process. So there was no clinical improvement, but we're still waiting for data on the biological signal. Did the antibody do what it was supposed to do in the brain?

Actress Rachel Weisz interviewed researchers to develop her scientist role in The Bourne Legacy. Image courtesy Universal Pictures

In The Bourne Legacy, Jeremy Renner plays Aaron Cross, a superspy whos been pharmaceutically tweaked to jump higher, think faster, punch harder, hear better and tolerate extreme cold. The surprising thing is, this type of gene-doped warrior is not a total figment of filmmaker Tony Gilroys imagination.

Charged with devising a new storyline to extend the Bourne franchise beyond Matt Damons amnesiac spy character, the Bourne Legacy writer-director thoroughly researched what he calls the United States espionocracy.

Gilroy became fascinated with behavior modification through gene-doping, and now says the idea that government-funded scientists have gone far beyond steroids to produce a new breed of hypertough warriors isnt as far-fetched as it seems.

Im not a scientist but Im a real good idiot screenwriter and layman reader of science, Gilroy told Wired in a phone interview. There are different ways to introduce chromosomal changes to affect genomics. You can hijack a virus, put in what you want and use that as the delivery system. I got really interested in this idea of genomic alteration, where you go in on a chromosomal level.

To vet the films viral-modification premise, Gilroy and actress Rachel Weisz whose Bourne Legacy character tests viruses on black-ops agents met with scientists working in the biotech industry. We wanted reassurance that we werent doing anything too far-fetched, Gilroy said. We had some really cool conversations with someone who had a CV very similar to Rachels character, and this person confirmed a lot of what we were doing in the film.

Ive been staggered to see articles where you have the Olympics main drug-testing guy saying they dont know if theyll be able to test for gene-doping, Gilroy said. Im going, Holy shit! This is the cutting edge of athletic enhancement. Theres a legitimate fear in the sports world that gene doping is going to be the next turn of the wheel.

Eager to avoid sci-fi extravagance in favor of reported fact, Gilmore read bioethicist Jonathan Moreno, bookmarked Wireds Danger Room blog, studied the Washington Posts Top Secret America series, monitored Darpas ongoing supersoldier experiments and surveyed the teeming biotech corridor anchored by Marylands Fort Detrick research center.

Bourne Legacy' s Gene-Doped Superspies Aren't as Far-Fetched as They Sound

SACRAMENTO Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Earlier research already has shown that the gene is defective in children with autism, but its effect on neurons in the brain was not known. The new studies in mice show that abnormal action of just this one gene disrupted energy use in neurons. The harmful changes were coupled with antisocial and prolonged repetitive behavior traits found in autism.

The research is published online today (Aug. 10) in the scientific journal PLoS ONE.

"A number of genes and environmental factors have been shown to be involved in autism, but this study points to a mechanism how one gene defect may trigger this type of neurological behavior," said study senior author Cecilia Giulivi, professor of molecular biosciences in the UC Davis School of Veterinary Medicine and a researcher affiliated with the UC Davis MIND Institute.

"Once you understand the mechanism, that opens the way for developing drugs to treat the condition," she said.

The defective gene appears to disrupt neurons' use of energy, Giulivi said, the critical process that relies on the cell's molecular energy factories called mitochondria.

In the research, a gene called pten was tweaked in the mice so that neurons lacked the normal amount of pten's protein. The scientists detected malfunctioning mitochondria in the mice as early as four to six weeks after birth.

By 20 to 29 weeks, DNA damage in the mitochondria and disruption of their function had increased dramatically. At this time the mice began to avoid contact with their litter mates and engage in repetitive grooming behavior. Mice without the single gene change exhibited neither the mitochondria malfunctions nor the behavioral problems.

The antisocial behavior was most pronounced in the mice at an age comparable in humans to the early teenage years, when schizophrenia and other behavioral disorders become most apparent, Giulivi said.

The research showed that, when defective, pten's protein interacts with the protein of a second gene known as p53 to dampen energy production in neurons. This severe stress leads to a spike in harmful mitochondrial DNA changes and abnormal levels of energy production in the cerebellum and hippocampus brain regions critical for social behavior and cognition.

GLASGOW, Scotland, Aug. 10 (UPI) -- Colon cancer was two to three times more likely to develop in mice with a faulty APC gene and fed high amounts of iron, researchers in Britain and Scotland say.

Researchers at Cancer Research UK at the University of Birmingham and the Beatson Institute for Cancer Research in Glasgow, Scotland, said mice with a faulty APC gene fed a diet low in iron did not develop bowel cancer.

"We've made a huge step in understanding how bowel cancer develops. The APC gene is faulty in around eight out of 10 bowel cancers but until now we haven't known how this causes the disease," Owen Sansom of the Beatson Institute for Cancer Research in Glasgow said in a statement. "It's clear that iron is playing a critical role in controlling the development of bowel cancer in people with a faulty APC gene."

The study might also explain why foods such as red meat, which have high levels of iron, are linked to an increased risk of bowel cancer.

In mice fed a diet with no iron, cells with a faulty APC gene were killed and bowel cancers did not develop, the study said. But, mice with a fully functioning APC gene did not develop bowel cancers, even when fed a diet high in iron, the researchers said.

The study was published in Cell Reports.

ScienceDaily (Aug. 10, 2012) Singing mice (scotinomys teguina) are not your average lab rats. Their fur is tawny brown instead of the common white albino strain; they hail from the tropical cloud forests in the mountains of Costa Rica; and, as their name hints, they use song to communicate.

University of Texas at Austin researcher Steven Phelps is examining these unconventional rodents to gain insights into the genes that contribute to the unique singing behavior -- information that could help scientists understand and identify genes that affect language in humans.

"We can choose any number of traits to study but we try and choose traits that are not only interesting for their own sake but also have some biomedical relevance," said Phelps. "We take advantage of the unique property of the species."

The song of the singing mouse song is a rapid-fire string of high-pitched chirps called trills used mostly used by males in dominance displays and to attract mates. Up to 20 chirps are squeaked out per second, sounding similar to birdsong to untrained ears. But unlike birds, the mice generally stick to a song made up of only a single note.

"They sound kind of soft to human ears, but if you slow them down by about three-fold they are pretty dramatic," said Phelps.

Most rodents make vocalizations at a frequency much too high for humans to hear. But other rodents typically don't vocalize to the extent of singing mice, which use the song to communicate over large distances in the wild, said Andreas George, a graduate student working in Phelps' lab.

Within the last year Phelps research on the behavior of the mouse has appeared in the journals Hormones and Behavior and Animal Behavior. But one of his newest research projects is looking deeper: examining the genetic components that influence song expression. Center stage is a special gene called FOXP2.

"FOXP2 is famous because it's the only gene that's been implicated in human speech disorders specifically," said Phelps.

Having at least one mutated copy of the gene has been associated with a host of language problems in humans, from difficulty understanding grammar to an inability to make the precise mouth movements needed to speak a clear sentence.

The FOXP2 gene is remarkably similar overall between singing mice, lab mice and humans, said Phelps. To find parts of the gene that may contribute to the singing mouse's songs, Phelps is searching for sequences unique to the singing mouse and testing them for evidence of natural selection, which weeds out mutations with no likely observable effect from those that are likely to contribute to singing behavior.

The Johns Hopkins Center for Inherited Disease Research (CIDR) program contract, which provides up to $101 million in research funding from the National Institutes of Health (NIH) to study the genetic contribution to human diseases, has been renewed for another five years.

"We are thrilled the NIH has awarded us this contract," says Kimberly Doheny, Ph.D., lead principal investigator of CIDR. "The bulk of the contract support allows us to generate sequencing or genotyping datasets for an average of 30 large genetic studies per year. A separate component of the contract supports the center's infrastructure, including the exploration of new technologies and the extensive IT infrastructure necessary to serve new data-intensive methods, like high-throughput genomic technologies."

CIDR, part of the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins, is a national resource for genetics researchers. Established in 1996, the center performs DNA genotyping and sequencing to identify genes linked to disease. CIDR also offers statistical genetics consultation to investigators. Researchers at CIDR thus far have analyzed over 620,000 DNA samples and identified genes associated with cancer, addiction, glaucoma, Parkinson's disease and many other genetic diseases.

Doheny, along with David Valle, M.D., Henry J. Knott Professor and director of the Institute of Genetic Medicine, and Alan Scott, Ph.D., will serve as the co-principal investigators of the center.

"CIDR's main goal is to support the genetics community a large group of molecular geneticists and bioinformaticians in their efforts to find genes that contribute to disease," says Valle. "We share our expertise with the Johns Hopkins community and offer fee-for-service access to our facility to all investigators."

The NIH program contract was initially awarded to CIDR in 1996 by the NIH and renewed in 2007 and now again in 2012. The contract receives funding from 14 NIH institutes. Investigators with grants from one of these institutes can apply for access to CIDR's sequencing and genotyping services. If the project is approved, the supporting NIH institute pays for the project directly through the contract. Access to the CIDR resources is also available on a fee-for-use basis through the Johns Hopkins Genetic Resources Core Facility (grcf.jhmi.edu).

The Johns Hopkins Center for Inherited Disease Research receives $101 million

While $34.7 million is a touch more than $34.5 million, that's not exactly huge quarter-over-quarter growth from Seattle Genetics' (Nasdaq: SGEN) Adcetris.

Still, investors seem to be shaking off the lackluster growth, and for good reason: Sales of Adcetris -- a drug for treating relapsed Hodgkin lymphoma and anaplastic large-cell lymphoma -- are a very small part of the long-term success of Seattle Genetics.

The light growth seems to be the result of declining business at academic centers, where sales dropped off as patients stopped treatment because they finished their therapy cycles or had a strong enough response to undergo a stem-cell transplant.

The number of community doctors using the drug increased in the second quarter, which is good news for the sales trajectory, as most of the lymphoma patients for whom Adcetris is appropriate are seen in the community setting.

Don't expect much growth in the second half, though; management is guiding for sales of $140 million to $150 million in 2012 -- either flat or a 17% increase from the first half of the year to the second half.

Seattle Genetics lost $12.3 million on a GAAP basis in the quarter but didn't actually burn any cash. In fact, the cash, cash equivalents, and investments increased by $21.5 million during the quarter. I don't know how long investors can expect that to continue, as the biotech is still using product manufactured prior to approval.

Of course, aside from Adcetris, Seattle Genetics can bring in cash by licensing out its antibody-drug conjugate technology, which has attracted some big names, including Roche, GlaxoSmithKline (NYSE: GSK) , Pfizer (NYSE: PFE) , and Abbott Labs (NYSE: ABT) .

Internally, Seattle Genetics' future depends on expanding the use of Adcetris into frontline setting for the two lymphomas it's currently approved to treat, as well as other types of cancer. The potential there towers over the $150 million Seattle Genetics will bring in this year.
