Choice Of Neurotransmitter Influenced By Electrical Activity In Developing Brain
Cascades of genetic signals determine which neurotransmitter a brain cell will ultimately use to communicate with other cells. Now a pair of reports from biologists at the University of California, San Diego, have shown for the first time that electrical activity in these developing neurons can alter their chemical fate - and change an animal's behavior - by tweaking this genetic program...

Study Identifies Molecular Mechanism Triggering Parkinson's Disease
Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady...

Our Genes Influence How Well Fad Diets Work
Ever notice some people seem to eat anything they want and never gain a pound, while others seem to gain weight just by looking at fattening foods? You may be seeing things correctly after all. According to research published in the July 2010 issue of Genetics, this may have a biological cause...

New York State Approves Quest Diagnostics' Fragile X Syndrome Test
An accurate, faster testing option to identify female carriers and other patients with genetic abnormalities that cause Fragile X Syndrome is now available to physicians in all fifty states with the recent approval in New York. Fragile X is the leading cause of inherited mental retardation and the most common known single gene cause of autism...

Genetic Architecture And The Evolution Of RNA Viruses
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the genome, or even other mutations co-occurring in that gene...

Peer-Reviewed Journal Publishes Findings By Viral Genetics' Lead Scientist
Research co-authored by Viral Genetics, Inc., (Pink Sheets: VRAL) lead scientist Dr. M. Karen Newell has been published in the peer-reviewed Journal of Leukocyte Biology (JLB). Newell's article identifies a potential mechanism that promotes chronic inflammation, a characteristic of most autoimmune diseases. Viral Genetics has been pursing treatments for Lyme Disease and HIV/AIDS...

Researcher Awarded NIH Grant To Study Proteins Linked To Genetic Diseases
A Florida State University biochemist who studies a group of proteins linked to several inherited diseases has received a major grant to advance his research toward a better understanding of cellular secretion, which is linked to a wide range of diseases. That research could one day lead to new treatments for those diseases...

Nanoblasts Move Molecules, Proteins & DNA Into Cells
Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells...

CMS Approves Clinical Study Of Genetic Test To Predict Patient Response To Leading Anticoagulant Drug Warfarin
Iverson Genetic Diagnostics announced the company has received approval from CMS to conduct a WARFARIN Clinical Study. The two-year study will assess the impact of genetic information in calculating doses and the changes in the rate of adverse events when initiating Warfarin drug therapy. These changes will be compared against doses initiated without genetic data...

First Step Towards Electronic DNA Sequencing: Translocation Through Graphene Nanopores
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules...

Gene Mutation Helps To Predict Drug Responsiveness In Cancer Patients
Drugs such as everolimus that target the protein mTOR are used to treat several forms of cancer, but not all patients respond to the treatment. A team of researchers, led by Alberto Bardelli, at the University of Turin Medical School, Italy, has now identified a way to help predict which patients will respond to such drugs...

Asuragen And Collaborators Report Results Using PCR-Only Technologies For The Comprehensive Molecular Assessment Of The Fragile X Gene
Asuragen, Inc. announced the results from two collaborative studies, one with the University of California Davis M.I.N.D. Institute and another with Rush University Medical Center, that demonstrate comprehensive molecular profiling of the Fragile X Mental Retardation (FMR1) gene using advanced PCR-based methods...

Advancing Technology Innovation Through Discovery: A New Partnership Between The Canadian Institutes Of Health Research And Genome Canada
Genome Canada and the Canadian Institutes of Health Research (CIHR) are pleased to announce a partnered program called "Advancing Technology Innovation through Discovery"...

Rare And Common Genetic Variations Responsible For High Triglyceride Levels In Blood
It can make blood look like cream of tomato soup. Patients with high levels of triglycerides in their blood, a disease called hypertriglyceridemia (HTG) face an increased risk for heart disease and stroke. HTG affects one in 20 people in North America and is also associated with obesity, diabetes and pancreatitis...

Study Finds That The GRB7 Gene Drives An Aggressive Form Of Breast Cancer
Oregon Health & Science University Knight Cancer Institute researchers found that the GRB7 gene drives an aggressive form of breast cancer and acts independently of the HER-2 gene, known to be a stimulator of breast cancer growth. Isolating the role of this gene could ultimately help fine-tune a patient's treatment and enable physicians to provide a more accurate prognosis...
