Mouse ovaries and testes age in unique ways

Aging leads to large changes in gene activity in the ovaries of mice, but only limited changes in testes, according to research published in the open-access journal, BMC Biology.

New genetic mutations involved in inflammatory intestinal disorders discovered

The discovery of new genetic mutations involved in inflammatory intestinal disorders could lead to a better understanding of these common conditions, two scientists told the annual conference of the European Society of Human Genetics today (Monday 2 June).

Distinct clusters of genetic markers linked to treatment responses for smoking cessation

Scientists have identified distinct clusters of genetic markers associated with the likelihood of success or failure of two smoking cessation treatments, nicotine replacement therapy (NRT) and the medication bupropion (Zyban). This study, supported by the National Institute on Drug Abuse (NIDA) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), was published in the June issue of the journal Archives of General Psychiatry.

Expert cautions against rushing into genetic testing

Just because scientific advances now allow individuals to learn their genetic make-up doesn't mean they should rush into genetic testing in hopes of making revolutionary improvements to their health, cautions a geneticist and practicing physician at the University of North Carolina at Chapel Hill.

Gene discovery could help answer basic questions of upright walking

What are the genes implicated in upright walking of humans? The discovery of four families in which some members only walk on all fours (quadrupedality) may help us understand how humans, unlike other primates, are able to walk for long periods on only two legs, a scientist will tell the annual conference of the European Society of Human Genetics tomorrow (Monday 2 June).

Researchers pinpoint gene mutations responsible for 10 percent of non-familial cases of schizophrenia

Scans of the genome of patients with schizophrenia have revealed rare spontaneous copy number mutations that account for at least 10 percent of the non-familial cases of the disease.

Soil bacteria may offer potential treatments for MRSA and cancer

Big pharma gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.

Spontaneous mutations widespread in non-familial schizophrenia

People with schizophrenia from families with no history of the illness were found to harbor eight times more spontaneous mutations - most in pathways affecting brain development - than healthy controls, in a study supported in part the National Institutes of Health?s (NIH) National Institute of Mental Health (NIMH). By contrast, no spontaneous mutations were found in people with schizophrenia who had family histories of the illness.

Timer genes control brain size

Experiments using fruit flies have helped a team at the MRC National Institute for Medical Research to identify genes that control how large the developing brain becomes.

Scientists sequence first female DNA

Geneticists of Leiden University Medical Centre (LUMC) are the first to determine the DNA sequence of a woman. She is also the first European whose DNA sequence has been determined. This has been announced by the researchers this morning, during a special press conference at 'Bessensap', a yearly meeting of scientists and the press in the Netherlands.

febit receives U.S. patent for microfluidic extraction method

febit today announced the receipt of US patent #7320862 on its microfluidic microarray-based method for extraction of DNA and RNA.

New cheaper method for mapping disease genes

Scientists at the Swedish medical university Karolinska Institutet have developed a new DNA-sequencing method that is much cheaper than those currently in use in laboratories. They hope that this new method will make it possible to map disease genes in large patient groups, which in turn can mean quicker breakthroughs for new treatments for a wide variety of diseases.

Yerkes researchers develop first transgenic nonhuman primate model of Huntington's disease

In the first study of its kind, researchers at the Yerkes National Primate Research Center, Emory University, in collaboration with researchers from the Department of Human Genetics at Emory's School of Medicine, have developed the first transgenic nonhuman primate model of Huntington's disease (HD), one of the most devastating human neurodegenerative diseases.

Extinct Tasmanian tiger genes shown to function in a mouse

Researchers from the University of Melbourne, Australia, and the University of Texas, USA, have extracted genes from the extinct Tasmanian tiger (thylacine), inserted it into a mouse and observed a biological function - this is a world first for the use of the DNA of an extinct species to induce a functional response in another living organism.

Mapping of prostate cancer genes opens the door to new treatments

Genetic changes during the initiation and progression of prostate cancer have eluded scientists to date. Now for the first time researchers have identified a specific gene expression profile of prostate cancer stem cells, with important implications for future treatments.

NIH launches undiagnosed diseases program

The National Institutes of Health (NIH) today announced a new clinical research program that will aim to provide answers to patients with mysterious conditions that have long eluded diagnosis. Called the Undiagnosed Diseases Program, the trans-NIH initiative will focus on the most puzzling medical cases referred to the NIH Clinical Center in Bethesda, Md., by physicians across the nation.

A transgenic monkey model of Huntington's disease developed

Scientists have developed the first genetically altered monkey model that replicates some symptoms observed in patients with Huntington's disease, according to a new study funded by the National Institutes of Health. Researchers are now able to better understand this complex, devastating and incurable genetic disorder affecting the brain.

Scientists discover why plague is so lethal

Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology.

Study implicates 350 gene regions in cancer development in the mouse

A large genetic study in mice has identified hundreds of genes involved in the development of cancer by examining the DNA of more than 500 lymphomas to find the cancer causing mutations.

Discovery of 250 new genes potentially involved in leukemia

Researchers have found over 250 new genes that are potentially involved in the development of leukemia. The research was performed in close collaboration between the Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital (Amsterdam, The Netherlands) and the Wellcome Trust Institute (Cambridge, UK) and will be published in the Friday May 16th issue of the scientific journal Cell.
