In Lung Cancer, Smokers Have 10 Times More Genetic Damage Than Never-Smokers
Newswise Lung cancer patients with a history of smoking have 10 times more genetic mutations in their tumors than those with the disease who have never smoked, according to a new study from Washington University School of Medicine in St. Louis.
None of us were surprised that the genomes of smokers had more mutations than the genomes of never-smokers with lung cancer, says senior author Richard K. Wilson, PhD, director of The Genome Institute at Washington University. But it was surprising to see 10-fold more mutations. It does reinforce the old message dont smoke.
The study appears online Sept. 13 in Cell.
Overall, the analysis identified about 3,700 mutations across all 17 patients with non-small cell lung cancer, the most common type. Twelve patients had a history of smoking and five did not. In each patient who never smoked, the researchers found at least one mutated gene that can be targeted with drugs currently on the market for other diseases or available through clinical trials. Across all patients, they identified 54 mutated genes already associated with existing drugs.
Whether these drugs will actually work in patients with these DNA alterations still needs to be studied, says first author Ramaswamy Govindan, MD, an oncologist who treats patients at Siteman Cancer Center at Barnes-Jewish Hospital and Washington University. But papers like this open up the landscape to understand whats happening. Now we need to drill deeper and do studies to understand how these mutations cause and promote cancer, and how they can be targeted for therapy.
Lung cancer is divided into two types small cell and non-small cell, the latter accounting for about 85 percent of all cases. Within non-small cell lung cancer are three further classifications. This current analysis included two of them. Sixteen patients had adenocarcinoma and one had large-cell carcinoma.
Govindan and Wilson also were involved in a larger genomic study of 178 patients with the third type, squamous cell carcinoma, recently reported in Nature. That study was part of The Cancer Genome Atlas project, a national effort to describe the genetics of common cancers.
Over the next year or so, we will have studied nearly 1,000 genomes of patients with lung cancer, as part of The Cancer Genome Atlas, says Govindan, who serves as a national co-chair of the lung cancer group. So we are moving in the right direction toward future clinical trials that will focus on the specific molecular biology of the patients cancer.
Indeed, based on the emerging body of genetic research demonstrating common mutations across disparate cancer types, Wilson speculates that the field may reach a point where doctors can label and treat a tumor based on the genes that are mutated rather than the affected organ. Instead of lung cancer, for example, they might call it EGFR cancer, after the mutated gene driving tumor growth. Mutations in EGFR have been found in multiple cancers, including lung, colon and breast.
This labeling is relevant, Wilson says, because today targeted therapies are approved based on the diseased organ or tissue. Herceptin, for example, is essentially a breast cancer drug. But he has seen lung cancer patients with mutations in the same gene that Herceptin targets.

Response Genetics’ Stock Zooms After GlaxoSmithKline Invests
Shares of Response Genetics Inc. jumped nearly 40 percent on Thursday after the Los Angeles diagnostic test developer said it raised $8.8 million in a private placement of its stock, mostly acquired by British drug maker GlaxoSmithKline Plc.
The private placement was composed of 8 million new common shares, priced at $1.10 a share. In its own press release, GlaxoSmithKline, which is based in the London suburb of Brentford, said it bought 5 million of the shares, giving it a 15.2 percent stake in Response Genetics, which specializes in molecular diagnostic tests for cancer.
Response Genetics, which provides services that help GlaxoSmithKline evaluate experimental cancer drugs and vaccines, said the remaining shares were bought by an existing large stockholder whom it did not identify.
"The capital raised will help support our continued efforts in building a sustainable business of high value genetic tests for cancer patients as well as a premier pharmaceutical services business, said Chief Executive Thomas Bologna in a statement. He added that the company hoped to grow top line revenue with the investment.
Prior to Thursdays announcement, shares had fallen 41 percent since the beginning of the year as the company reported declining revenue because old service contracts expired. Bologna, who joined the company in December, said in March that the company planned to more aggressively pursue new collaborations with pharmaceutical clients through its services businesses.
Shares closed up 33 cents, or 37 percent, to $1.23 on the Nasdaq.

Single gene cause of insulin sensitivity may offer insight for treating diabetes
Public release date: 12-Sep-2012 [ | E-mail | Share ]
Contact: University of Oxford press office press.office@admin.ox.ac.uk 44-186-528-0530 University of Oxford
The first single gene cause of increased sensitivity to the hormone insulin has been discovered by a team of Oxford University researchers.
The opposite condition insulin resistance is a common feature of type 2 diabetes, so finding this cause of insulin sensitivity could offer new opportunities for pursuing novel treatments for diabetes.
Although mutations in the PTEN gene cause a rare condition with increased risk of cancer, the biological pathways the gene is involved in could offer promising targets for new drugs.
The Oxford University researchers, along with colleagues at the Babraham Institute in Cambridge, UK, and the Churchill Hospital in Oxford, UK, report their findings in the New England Journal of Medicine. The study was funded by the Wellcome Trust, the Medical Research Council, the National Institute for Health Research Oxford Biomedical Research Centre, and the Biotechnology and Biological Sciences Research Council.
'Insulin resistance is a major feature of type 2 diabetes,' says Dr Anna Gloyn of the Oxford Centre for Diabetes, Endocrinology and Metabolism at the University of Oxford, who led the work. 'The insulin-producing cells in the pancreas may be working hard and pumping out lots of insulin, but the body's cells no longer respond.
'Finding a genetic cause of the opposite insulin sensitivity gives us a new window on the biological processes involved. Such understanding could be important in developing new drugs that restore insulin sensitivity in type 2 diabetes.'
The PTEN gene encodes for an enzyme that is part of the insulin signalling pathway in the body. It is known to have a role in controlling the body's metabolism, and to play a part in cell growth. The Oxford team was interested in learning more about this dual role.
There is an inherited genetic condition called Cowden syndrome caused by faults in the PTEN gene. It is very rare and is thought to affect perhaps one in 200,000 people, with around 300 people with the condition in the UK. PTEN's role in cell growth sees people with Cowden syndrome develop many benign polyps in their skin, mouth and bowel, and have a higher risk than the general population of developing breast cancer, thyroid cancer and womb cancer.

Scary Parents Both Fertile And Feral In 'Breed'
In his satirical horror novel Breed, Chase Novak has hit upon the perfect blend of terrifying real-life topics: genetic engineering and the mating habits of New York's wealthy 1 percent. The story of two rich but barren Manhattanites, the novel begins as a snarky tour of fertility treatment chic among the city's moneyed classes. But it quickly gets a lot weirder.
On the recommendation of another couple, blue-blood attorney Alex Twisden and his editor wife, Leslie, have one last go at baby making in the bizarre clinic of a creepy Slovenian doctor. The treatment works. They become incredibly fertile but unfortunately they become feral, too.
Novak is the pen name of Scott Spencer, author of the 1970s classic Endless Love, and here he has repurposed his literary flair for observation into grisly narrative schadenfreude. Every disgusting detail ends with a sarcastic barb, a nasty little stinger aimed at the well-toned bodies of our high-toned protagonists. One of the immediate side effects of the mad doctor's treatment is that Alex and Leslie get incredibly hairy and lose their inhibitions about things like hygiene and chewing on the furniture. They devote most of their time to rutting, eating increasingly grotesque slabs of meat and (in Leslie's case) seeking out people willing to do all-over body waxing once a day.
The bulk of Breed is told from the perspective of the Twisden twins, Alice and Adam, who at the age of 10 have realized there is something deeply wrong with their parents. Through the children's eyes, we see that Alex's family manse has fallen into ruin. There is a clever fable about class here, as the Twisdens' tumble down the evolutionary tree mirrors their fall down the economic ladder. No longer able to work, they've sold off their antique furniture to pay for the twins' expensive schooling. They are the monstrous embodiment of downward mobility, struggling to keep up appearances with their rich neighbors.
Fearing that they're about to become their parents' next meal, Alice and Adam flee their home one night Adam running to his saintly, gay teacher's house, and Alice into the clutches of a group of feral children like herself who live in Central Park. Novak imagines that the homeless kids who haunt the park are all the spawn of rich New Yorkers who were patients of the mad Slovenian fertility doctor. Again, it's an interesting metaphor for downward mobility and gives us a glimpse of a genetic-engineering nightmare future. In other words, it's scientifically implausible but symbolically rich.
The main problem with Breed is Novak's clumsy effort to offer us a kind of civilized antidote to the Twisdens in Adam's gay teacher, whose main attributes are kindness, selflessness and about-to-be-lunchmeat-ness. Novak also struggles to depict Adam and Alice vividly; they come across as automatons or placeholders, rather than real children who are discovering that they aren't like any other humans they know.
Still, the book is a delightfully nauseating read. And it's the perfect dark fairy tale for these times, when more than a few readers might secretly find themselves wishing that the world's elites would be brought so low as to start pooping in their own posh living rooms.
Annalee Newitz writes about the intersection of science and culture. She's the editor-in-chief of io9.com and the author of a forthcoming book about how humans will survive a mass extinction.

Genetic test predicts risk for autism spectrum disorder
ScienceDaily (Sep. 11, 2012) A team of Australian researchers, led by University of Melbourne has developed a genetic test that is able to predict the risk of developing autism spectrum disorder (ASD).
Lead researcher Professor Stan Skafidas, Director of the Centre for Neural Engineering at the University of Melbourne said the test could be used to assess the risk for developing the disorder. "This test could assist in the early detection of the condition in babies and children and help in the early management of those who become diagnosed," he said. "It would be particularly relevant for families who have a history of autism or related conditions such as Asperger's syndrome," he said.
Autism affects around one in 150 births and is characterized by abnormal social interaction, impaired communication and repetitive behaviours. The test correctly predicted ASD with more than 70 per cent accuracy in people of central European descent. Ongoing validation tests are continuing including the development of accurate testing for other ethnic groups.
Clinical neuropsychologist, Dr Renee Testa from the University of Melbourne and Monash University, said the test would allow clinicians to provide early interventions that may reduce behavioural and cognitive difficulties that children and adults with ASD experience. "Early identification of risk means we can provide interventions to improve overall functioning for those affected, including families," she said.
A genetic cause has been long sought with many genes implicated in the condition, but no single gene has been adequate for determining risk. Using US data from 3,346 individuals with ASD and 4,165 of their relatives from Autism Genetic Resource Exchange (AGRE) and Simons Foundation Autism Research Initiative (SFARI), the researchers identified 237 genetic markers (SNPs) in 146 genes and related cellular pathways that either contribute to or protect an individual from developing ASD.
Senior author Professor Christos Pantelis of the Melbourne Neuropsychiatry Centre at the University of Melbourne and Melbourne Health said the discovery of the combination of contributing and protective gene markers and their interaction had helped to develop a very promising predictive ASD test.
The test is based on measuring both genetic markers of risk and protection for ASD. The risk markers increase the score on the genetic test, while the protective markers decrease the score. The higher the overall score, the higher the individual risk.
"This has been a multidisciplinary team effort with expertise across fields providing new ways of investigating this complex condition," Professor Pantelis said.
The study was undertaken in collaboration with Professor Ian Everall, Cato Chair in Psychiatry and Dr Gursharan Chana from the University of Melbourne and Melbourne Health, and Dr Daniela Zantomio from Austin Health.
The next step is to further assess the accuracy of the test by monitoring children who are not yet diagnosed over an extended study. The study has been published today in the journal Molecular Psychiatry.

Licensing Executives Society Annual Meeting Keynote Speaker Eric Topol Says High Tech Medical and Digital Innovations …
WASHINGTON--(BUSINESSWIRE)-- The convergence of new high tech medical and digital tools are revolutionizing health care, according to renowned cardiologist and genetic researcher Eric Topol, who is working to secure widespread use of these innovations to design treatments specifically for patient populations based on their unique genetic maps. During an interview promoting his upcoming address at the Licensing Executives Society (U.S.A. and Canada) Annual Meeting, October 14-17 in Toronto, Dr. Topol urged the medical community to reboot its approach. (www.les2012.org/podcast)
Its a really extraordinary time in medicine that requires us to reboot how we operate as a profession and how we render care. It has a profound rippling effect across the life science industry, academics and the regulatory authority because we have new found capabilities of digitizing each human being to the essence of what makes each person tick, said Dr. Topol.
In his LES keynote address, Connecting & Collaborating: The Convergence of Life Sciences and High Tech, Dr. Topol, who in 2012 was voted the Most Influential Physician Executive in Health Care by Modern Healthcare and Doctor of the Decade by the Institute for Scientific Information, will share his vision for the future and discuss the complicated implications of change.
Were not talking about a little disruption anymore. Were talking about radical innovation that has across the board impact, said Dr. Topol, who added that there has been "remarkable resistance" from the medical community toward the new digital infrastructure he feels is necessary to fully embrace this new individualized and more precise approach to preventive medicine.
At the same time, Dr. Topol says that while the top 3 medicationsHumira, Enbrel, and Remicade-- bring cumulative annual sales of nearly $30 billion, only 40 percent of patients respond to them. He calls the current blockbuster model of pharmaceutical development busted, and suggests that by leveraging new technologies and smaller clinical trials, therapeutics could be advanced more quickly at a lower cost and with enhanced efficacy.
Just as the health care system is in economic crisis, so are the pharmaceutical and biotech industries because their discovery pipelines have run dry and their methods of developing new drugs rely on clinical trials that are immense in size and cost. All of this can be changed if one can demonstrate overwhelming efficacy in a small number of individuals because of some specific information that makes these people likely to respond favorably to a drug, device or diagnostic. That is an extraordinary change.
Topols appearance has ignited widespread interest from IP, licensing and business professionals who are eager to hear how the IP evolution is impacting the life sciences and what it may mean for other industry sectors.
This is a watershed time for those of us in the pharma and biotech industries, said Pamela Demain, Executive Director of Corporate Licensing, Merck & Co. Inc. Eric Topols vision for change builds a powerful case for the convergence of medicine with high tech innovations and the resulting benefits to society. Im really looking forward to his presentation.

Genetics Predict Smoking Addictions
Editor's Choice Main Category: Smoking / Quit Smoking Also Included In: Genetics Article Date: 11 Sep 2012 - 16:00 PDT
Current ratings for: Genetics Predict Smoking Addictions
1 (1 votes)
In a new study conducted by the Montreal Neurological Institute and Hospital, The Neuro, McGill University, findings show people with a fast nicotine metabolism have a greater brain response to smoking signals than those with a slow nicotine metabolism. Earlier research establishes that greater reactivity to smoking signals anticipates decreased ability to quit smoking and environmental cues encourage greater nicotine intake in humans as well as animals.
As seen in other studies, tobacco use is still one of the leading causes of preventable death and disease in the United States. This new discovery that nicotine metabolism rates impact the brain's response to smoking can potentially lead the way for customized smoking abstinence programs based on genetics.
Smoking prompts such as the sight of smoking, or a cigarette, are linked to cigarette use and relapse. Nicotine metabolism performed by a liver enzyme, can be fast or slow and affects the level of nicotine in the blood that travels to the brain. This particular study tested participants for their enzyme genotype and their nicotine metabolism rates.
Smokers aged 18 to 35 who consumed 5 to 25 cigarettes daily for at least two years were followed during the study. Brain response to smoking cues was examined by functional MRIs. Fast metabolizers had considerably higher responses to visual signals than slow metabolizers in areas of the brain associated with memory, motivation and reward.
Clinician-scientist Dr. Alain Dagher, lead investigator at The Neuro says,
Slow metabolizers, on the other hand, have constant nicotine levels in the blood throughout the day and are less inclined to develop conditioned responses to signals. For these users, smoking is not linked with short nicotine surges, rather, it is used to maintain cognitive abilities such as attention span, memory, and stress relief. As seen in previous research, genetics play a role in the most successful way to treat smoking addiction.
Authors suggest future studies should focus on smoking abstinence programs designed for individuals. Measuring metabolism rates as a part of the decision making process for treatment may be effective. Patients with slow nicotine metabolism will most likely benefit from long-acting cholinergic drugs such as the nicotine patch, while those with fast nicotine metabolism will benefit from craving-induced therapy such as non-nicotine based buproprion, an anti depressant used to stop smoking.

Restoring Children's Immune Systems with Refinements in Gene Therapy
Washington, D.C. - infoZine -Researchers have demonstrated that a refined gene therapy approach safely restores the immune systems of some children with severe combined immunodeficiency (SCID). The rare condition blocks the normal development of a newborn's immune system, leaving the child susceptible to every passing microbe. Children with SCID experience chronic infections, which usually triggers the diagnosis. Their lifespan is two years if doctors cannot restore their immunity.
The findings from facilities including the National Institutes of Health, the University of California, Los Angeles (UCLA), and the Children's Hospital Los Angeles, are reported in the Sept. 11, 2012, advanced online issue of the journal Blood, the official journal of the American Society of Hematology.
In the 11-year study, the researchers tested a combination of techniques for gene therapy, arriving at one that produced normal levels of immune function for three patients.
"Doctors who treat patients with SCID have had limited treatment options for too long," said Dan Kastner, M.D., Ph.D., scientific director of the National Human Genome Research Institute (NHGRI), part of the NIH. "The research teams and the patients who have participated in the studies have together achieved an impressive advance toward a cure that is welcome news for both the scientific and patient communities."
Gene therapy is an experimental method for treating patients with genetic diseases. It is intended to integrate functioning genes among those naturally existing in the cells of the body to make up for faulty genes. Researchers in the current study tested a set of methods to improve outcomes for children with a particular form of SCID.
"This is a highly rewarding study for those of us in the clinic and lab," said Fabio Candotti, M.D., a senior author and a senior investigator in NHGRI's Genetics and Molecular Biology Branch. "Not only have we realized an important advancement in gene therapy, but we have seen a renewal of health in our patients."
While rare, SCID became widely known because of the remarkable boy-in-the-bubble story of the 1970s. The story was based in part on a boy named David Vetter, who lived for 13 years in a plastic isolation unit to protect him from infections. He died following an unsuccessful bone marrow transplant that doctors had hoped would repair his immune system.
SCID has many causes. In one type, a gene that produces the adenosine deaminase (ADA) enzyme becomes mutated and fails to produce the normal enzyme. Without ADA, a chemically altered form of adenosine, one of DNA's building blocks, accumulates in rapidly dividing bone marrow cells, killing them and destroying the immune system in the process. Normal bone marrow makes healthy white blood cells, or lymphocytes, which are the key players in the immune response that reacts against harmful bacteria and destroys cells infected by viruses. ADA deficiency accounts for some 15 percent of SCID cases.
If there is a sibling available whose blood is compatible with the patient's blood, doctors can perform a bone marrow transplant. If not, a form of the enzyme has to be administered by injection regularly to maintain the child's immune system.
Researchers seek to cure the disease by inserting a healthy copy of the ADA gene into continuously dividing bone marrow cells called stem cells. Bone marrow stem cells give rise to all other blood cells, including oxygen-carrying red cells and the white cells of the immune system. The healthy ADA gene would then produce enough enzyme to prevent immune-destroying toxicity.

Restoring Children's Immune Systems with Refinements in Gene Therapy
Recommendation and review posted by Bethany Smith
'Bubble babies' immune systems restored
LOS ANGELES UCLA stem cell researchers have found that a gene therapy regimen can safely restore immune systems to children with so-called "bubble boy" disease, a life-threatening condition that if left untreated can be fatal within one to two years.
In the 11-year study, researchers were able to test two therapy regimens for 10 children with ADA-deficient severe combined immunodeficiency (SCID), which has come to be known as "bubble boy" disease because some of its victims have been forced to live in sterile environments.
During that time, the researchers refined their approach to include a light dose of chemotherapy to help remove many of the blood stem cells in the bone marrow that were not creating the enzyme adenosine deaminase (ADA), which is critical for the production and survival of healthy white blood cells, said study senior Dr. Donald Kohn, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
The refined gene therapy and chemotherapy regimen proved superior to the other method tested in the study, restoring immune function to three of the six children who received it, said Kohn, who is also a professor of pediatrics and of microbiology, immunology and molecular genetics in UCLA Life Sciences Division. An even further-refined regimen using a different type of virus delivery system will be studied in the next phase of the study, which already has enrolled eight of the 10 patients needed.
The study appears today (Sept. 11) in the advance online issue of the peer-reviewed journal Blood.
"We were very happy that in the human trials we were able to see a benefit in the patients after we modified the protocol," Kohn said. "Doctors treating ADA-deficient SCID have had too few options for too long, and we hope this will provide them with an efficient and effective treatment for this devastating disease."
Children born with SCID, an inherited immunodeficiency, are generally diagnosed at about 6 months old. They are extremely vulnerable to infectious diseases and don't grow well. Chronic diarrhea, ear infections, recurrent pneumonia and profuse oral candidiasis commonly occur in these children. SCID occurs in about one of every 100,000 births.
Currently, the only treatment for ADA-deficient SCID calls for injecting patients twice a week with the necessary enzyme, Kohn said, a lifelong process that is very expensive and often doesn't return the immune system to optimal levels. These patients also can undergo bone marrow transplants from matched siblings, but matches can be very rare.
About 15 percent of all SCID patients are ADA-deficient. Kohn and his team used a virus delivery system that he had developed in his lab in the 1990s to restore the gene that produces the missing enzyme necessary for a healthy immune system. To date, about 40 children with SCID have received gene therapy in clinical trials around the world, Kohn said.
Two slightly different viral vectors were tested in the study, each modified to deliver healthy ADA genes into the bone marrow cells of the patients so the needed enzyme could be produced and make up for the cells that don't have the gene. Four of the 10 patients in the study remained on their enzyme replacement therapy during the gene therapy study. There were no side effects, but their immune systems were not sufficiently restored, Kohn said.

Gene linking cataracts and Alzheimer's disease identified
ScienceDaily (Sep. 11, 2012) In a recent study, investigators at Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) identified a gene linking age-related cataracts and Alzheimer's disease. The findings, published online in PLoS ONE, contribute to the growing body of evidence showing that these two diseases, both associated with increasing age, may share common etiologic factors.
Gyungah Jun, PhD, from the departments of medicine, ophthalmology and biostatistics at BUSM and BUSPH, served as the study's lead author. Lindsay A. Farrer, PhD, professor of medicine, neurology, ophthalmology, genetics & genomics, epidemiology and biostatistics and chief of the Biomedical Genetics Section at BUSM, was the study's senior author.
Using the Framingham Offspring Eye Study cohort, investigators looked at brain MRI findings on or after 10 years from the original eye exam and concluded that there was a significant correlation between a quantitative measure of cortical cataract and several Alzheimer's disease-related measures of brain degeneration, in particular volume of the temporal horn which is a brain structure that is progressively enlarged in patients with Alzheimer's disease. Another strong correlation in these same individuals, between cortical cataract formation and poorer performance on several cognitive tests administered at the time of the MRI scan, further supports this link.
With such a link not confounded by age or sex, the investigators then performed a genome-wide association study looking at nearly 190,000 single-nucleotide polymorphisms (SNPs), or DNA sequence variations. Three intronic (non-coding) SNPs in the gene encoding -catenin came to the fore. This protein is a key component in cell adherence and formation of cell junctional structures. Previously, -catenin was also implicated in brain and eye development, but not directly in either cataracts or Alzheimer's disease. To establish a more direct link of -catenin to Alzheimer's disease, the researchers transfected into neuronal cells -catenin bearing a mutation near the location of the top-associated SNPs and observed a significant and specific increase in the toxic form of amyloid , the protein that aggregates in Alzheimer brains and thought to be central to development of the disorder. In addition, the researchers found increased deposits of -catenin in lens tissue obtained from autopsy-confirmed Alzheimer's cases but not from subjects lacking Alzheimer's-associated neuropathology.
"Though much work remains to be done, a link between cataracts and Alzheimer's disease supports the idea of a systemic rather than brain-limited focus for processes leading to Alzheimer's disease," said Farrer. "This study gives hope that we are moving toward earlier diagnosis and new treatment targets for this debilitating disease."
Juliet Moncaster, PhD, from the department of psychiatry; Sudha Seshadri, MD from department of neurology and associate professor of the Framingham Heart Study; Jacqueline Buros, BS, from the department of medicine; Ann C. McKee, MD, from the departments of neurology, pathology and laboratory medicine, the Boston University Alzheimer's Disease Center, and the Bedford Veterans Administration Hospital; and Phillip A. Wolf, MD, of the departments of neurology, epidemiology and professor of the Framingham Heart Study of BUSM and BUSPH, contributed to this paper. Researchers from the University of Toronto, the Bedford Veterans Administration Hospital, the Universit Laval and the University of Cambridge also collaborated on this study.

Vanderbilt's BioVU Databank Now World's Largest Human DNA Repository Linked to Searchable, Electronic Health Information
Newswise African-Americans dont get kidney stones as frequently as Caucasians.
Are they protected genetically? If so, identifying the genetic factors that retard kidney stone formation could lead to new ways to treat or even prevent this painful condition, according to Vanderbilt University researcher Todd Edwards, Ph.D.
Kidney stones afflict one of every 11 Americans and cost the country more than $2 billion annually. Avoiding them could really make a difference for a lot of people, and could cut health costs dramatically, he said.
Until recently, teasing out complicated kidney stone genetics would have required years of study, tens of thousands of patients and hundreds of millions of dollars. Now thanks to BioVU, Vanderbilts massive DNA databank, the mother lode is within reach.
This month BioVU logged in its 150,000th unique genetic sample. It is now the worlds largest collection of human DNA linked to searchable, electronic health information, said Dan Roden, M.D., assistant vice chancellor for Personalized Medicine at Vanderbilt and BioVUs principal investigator.
BioVU began collecting DNA in 2007. Discarded blood specimens from Vanderbilt patients are sent to the DNA Resources Core, where the genetic material is extracted and stored. If patients check a box on a consent form, their leftover blood will not be used, but few choose to opt out.
The DNA samples are bar-coded and, along with their matching electronic health records, scrubbed of information that could identify individual patients.
The resulting genetic gold mine enables Vanderbilt researchers to quickly pull and analyze the DNA of hundreds of people with particular health conditions or responses to medication.
Before proceeding, BioVU investigators must be approved by Vanderbilts Institutional Review Board, sign a data use agreement, and determine, with the help of a BioVU project manager, the feasibility of their idea. Their proposals are then considered by separate pre-review and full review committees consisting of Vanderbilt faculty members.
To date, more than 50 BioVU studies have been approved and are under way.

Home genetic testing for alcoholism carries perils
Being told you have a genetic predisposition to alcoholism could make you feel you have less control over your drinking, a new study suggests.
The unique study adds to growing concern about the potential perils of direct-to-consumer genetic tests.
Psychologist Ilan Dar-Nimrod from the University of Sydney and colleagues report their findings in the journal Genetics in Medicine.
He says the latest findings show how genetic information has the power to change a person's emotional state, behaviour and attitudes.
"We have about 1,600 genetic tests available now," Dar-Nimrod tells the Australian Broadcasting Corporation. "We should have better knowledge about how to communicate these results in a manner that doesn't create harm."
He says for a few genetic-related diseases, having a particular gene means you will definitely get the disease, unless you die of other causes first.
But in 98 per cent of cases the gene only increases your risk of a condition and that risk may be very small or very uncertain.
Despite the lack of certainty around the impact of many disease-related genes, Dar-Nimrod says there is some evidence that people who test positive for them can become fatalistic and believe they will definitely develop the condition in question.
He says such "genetic determinism" is encouraged by media reports that imply a greater risk from such genes than there actually is.
Dar-Nimrod and colleagues set up the first randomized experiment to investigate the psychological and behavioural impact of receiving personalized genetic information of this kind.

How genetics shape our addictions
Public release date: 11-Sep-2012 [ | E-mail | Share ]

This press release is available in French.
Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. A study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows that people with genetically fast nicotine metabolism have a significantly greater brain response to smoking cues than those with slow nicotine metabolism. Previous research shows that greater reactivity to smoking cues predicts decreased success at smoking cessation and that environmental cues promote increased nicotine intake in animals and humans. This new finding that nicotine metabolism rates affect the brain's response to smoking may lead the way for tailoring smoking cessation programs based on individual genetics.
Smoking cues, such as the sight of cigarettes or smokers, affect smoking behavior and are linked to relapse and cigarette use. Nicotine metabolism, by a liver enzyme, also influences smoking behavior. Variations in the gene that codes for this enzyme determine slow or fast rates of metabolism and therefore, the level of nicotine in the blood that reaches the brain. In the study smokers were screened for their nicotine metabolism rates and their enzyme genotype. Participants were aged 18 35 and smoked 5-25 cigarettes daily for a minimum of 2 years. People with the slowest and fastest metabolism had their brain response to visual smoking cues measured using functional MRI. Fast metabolizers had significantly greater response to visual cigarette cues than slow metabolizers in brain areas linked to memory, motivation and reward, namely the amygdala, hippocampus, striatum, insula, and cingulate cortex.
"The finding that nicotine metabolism rate has an impact on the brain's response to smoking cues supports our hypothesis that individuals with fast nicotine metabolism rates would have a greater brain response to smoking cues because of close coupling in everyday life between exposure to cigarettes and surges in blood nicotine concentration. In other words they learn to associate cigarette smoking with the nicotine surge," says clinician-scientist Dr. Alain Dagher, lead investigator at The Neuro. "In contrast, individuals with slow metabolism rates, who have relatively constant nicotine blood levels throughout the day, are less likely to develop conditioned responses to cues. For them, smoking is not associated with brief nicotine surges, so they are smoking for other reasons. Possibilities include maintenance of constant brain nicotine levels for cognitive enhancement (ie, improved attention, memory), or relief of stress or anxiety. "
Future research could focus on improving smoking cessation methods by tailoring treatments for different types of smokers. One possibility is to measure the rate of nicotine metabolism as part of the therapeutic decision-making process. For example, targeting cue-induced relapse risk may not help those with slow nicotine metabolism, who are more likely to benefit from long-acting cholinergic drugs such as the nicotine patch, consistent with previous clinical trials. Conversely the use of non-nicotine based therapies aimed at reducing craving may help fast metabolizers, as demonstrated for buproprion, an anti-depressant that has been used for smoking cessation.

Viral Genetics’ Subsidiary, VG Energy, Commencing Sales of LipidMax™
SAN MARINO, Calif.--(BUSINESS WIRE)--
Viral Genetics (VRAL) majority-owned subsidiary, VG Energy, has contracted with Eno Research Chemicals & Custom Synthesis Group for production of its LipidMax lipid enhancement compound, in sufficient capacity to meet demand from commercial and research end-users worldwide.
Orders for LipidMax can be placed at https://store.vgenergy.net/. Once approved for purchases, customers will be shipped LipidMax in 10g units. Additional information is also available at lipidmax@vgenergy.net.
LipidMax, the first product marketed by VG Energy, is a lipid-enhancement compound for use in the production of oils from algae, corn, palm, and other plants or plant-like organisms and is based on the Companys exclusively licensed Metabolic Disruption Technology (MDT).
Independent testing has shown that, when treated with LipidMax, the yields from several algae and algae-like species including Schizochytrium, Prymnesium parvum, and Chlamydomonas reinhardtii, have shown significant increases in oil (lipid) yields. Similar, if not stronger, results have been observed in palm and other oil-producing plants. The Company believes that LipidMax should generate oil-enhancing results in most other species of plants and plant-like organisms beyond those mentioned, and is continuing testing to validate and quantify this.
The oil yield increase is thought to provide a possible catalyst for changing the economic feasibility for algal-derived biofuels in the marketplace, making biofuels more cost-competitive, when compared to petroleum-based fuels. Similar cost-reduction effects in plant oils used as food, nutraceuticals and cosmetics should also result from productivity-enhancement.
The company joins a newly emerging category of businesses called intermediates1 in the biofuels and bio-chemical sectors. These products can be utilized in the production of an array of fuels, chemicals, flavors, fragrances and other end products. Intermediates constitute building blocks and intermediate steps upon which other processes and products are built, and as such can become integral to building the value chain in these rapidly growing bio-based industries.
VG Energys Chief Scientist, Dr. M. Karen Newell-Rogers, noted that the Eno Research Chemicals and Custom Synthesis Group is fully cGMP- and cGLP-compliant, has passed a rigorous set of internal testing protocols, and the product produced at the facility meets the companys standards for chemical consistency, purity and yield. When scaled up to commercially viable quantities, the LipidMax produced at this facility meets or exceeds the same quality standards we established using smaller research-grade batches at the Agrilife facilities. The process of commercial or industrial scale-up of a chemical such as our product can sometimes alter the ultimate activity of a compound, but LipidMax produced at scaled up production protocols has shown to match the results we observed during initial evaluations.
Haig Keledjian, Viral Genetics CEO said, This marks the transition to commercialization from a purely research based company and we are very pleased and excited to now commence sales of our LipidMax product to customers in the bio-fuels, and high quality edible and nutraceutical oil markets.
Mr. Keledjian continued, We expect that initial customers will be industrial laboratories and academic research institutions looking to establish and verify the economic advantages of LipidMax that we have demonstrated in our own and independent testing. As end users attain increased yields of usable oil in commercial size quantities, we anticipate a rapid and widespread awareness of LipidMax, leading to adoption of LipidMax in a host of industries worldwide including algal biofuel and palm oil, amongst others.

New Therapy for Bubble Babies
When Jessica Ainslie had her son Colton, she knew there was something wrong. Born prematurely, he weighed just 2 pounds, 9 ounces at birth, and he had to spend time in the neonatal intensive care unit before he could come home.
Thought to be out out of the woods, Colton then started developing breathing problems and was vomiting often, just a few months later.
It just kept getting worse. He wasnt eating a whole lot, and he couldnt keep anything down, Ainslie, from Peoria, Ariz., told FoxNews.com. We took him to the ER a couple times; they kept giving him fluids and sending him back home. But I knew there was something wrong with my kid. I had that mom gut feeling.
Multiple blood tests were done on Colton, but nothing definitive came up. Finally, one of Ainslies doctors said she was going to test for SCID, a possible diagnosis that made the new mom incredibly anxious.
For small children with severe combined immunodeficiency (SCID) more famously known as bubble boy syndrome disease and infection are a constant source of worry due to a weakened, or almost non-existent immune system. If left untreated, the condition is fatal in just one to two years.
Sure enough, Coltons blood work showed that he had ADA-deficient SCID, a form of SCID that affects 15 percent of SCID patients. While some treatments exist for those suffering from the disease, options are mostly limited to rare bone marrow matches or frequent drug injections that can last the entirety of the childs life. Though helpful, these treatments dont always work and can come with terrible side effects and high costs.
Devastated by the diagnosis, Ainslie was offered some hope when she was asked if they could Air Evac 10-month-old Colton to Dr. Donald Kohns office at UCLA, one of the leading doctors in ADA-deficient SCID. Now, after having participated in a new gene therapy study developed by Kohn, Colton and eventually his baby sister Abbygail are living normal lives, nearly SCID-free.
Be their own donor
Just about the time Colton was diagnosed, Kohn had been working on a novel gene therapy treatment for children with SCID. In collaboration with researchers from both the University of California at Los Angeles and that National Institute of Health, Kohn and his colleagues have spent 11 years creating and testing this new therapy, which is capable of restoring immune systems in children with ADA-deficient SCID.
What were doing with gene therapy is having the patient be their own donor, study author Kohn, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, told FoxNews.com. We insert the gene theyre missing and transport it back through their system.
