Population genetic studies may have limited role in schizophrenia

Studying the genetics of people in the general population who have psychotic experiences is unlikely to yield useful information about schizophrenia, say researchers.

Meta-analysis shows that XRCC1 Arg399Gln polymorphism may be a biomarker of glioma susceptibility

DNA damage is an important mechanism of glioma. X-ray cross-complementing group 1 (XRCC1) is a DNA repair gene that participates in the base excision repair pathway. To date, many studies have been performed to investigate the association between the XRCC1 polymorphisms and risk of cancers such as breast cancer, and gastroesophageal cancer, but the number of studies that focused on glioma is relatively small.

Researchers discover link between NOX4 enzyme and osteoporosis

Genkyotex, the leading developer of NOX enzyme inhibitors, announced today that a group of collaborators have discovered a link between the enzyme NOX4 and development of osteoporosis.

Study finds inherited GATA3 gene variation increases risk of developing pediatric leukemia

Research led by St. Jude Children's Research Hospital scientists has linked an inherited gene variation to a nearly four-fold increased risk of developing a pediatric acute lymphoblastic leukemia (ALL) subtype that is associated with a poor outcome.

Researchers identify key therapeutic target for cancers driven by KRAS protein

Patients with cancers driven by the protein KRAS, which are particularly hard to treat, may benefit from small molecules that attach to and disrupt the function of a KRAS-containing protein complex, according to results presented here at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, held Oct. 19-23.

Study: Skin tanning gene linked to higher risk for testicular cancer in white men

A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England.

Genetic mutation that protects skin from UV radiation may cause testicular cancer in Caucasian

A Ludwig Cancer Research study published in Cell today identifies a common mutation that dramatically increases the risk for testicular cancer—and describes a likely molecular mechanism by which it exerts that effect.

Small interfering RNAs in mammals act as specific antiviral weapons

Many viral infections are nipped in the bud by the innate immune response. This involves specific proteins within the infected cell that recognize the virus and trigger a signalling cascade - the so-called interferon response. This activates a protective mechanism in neighbouring cells and often results in the death of the primarily infected cell.

Gene mutation offers clues to development of diverse neurological disorders

A research team, headed by Theodore Friedmann, MD, professor of pediatrics at the University of California, San Diego School of Medicine, says a gene mutation that causes a rare but devastating neurological disorder known as Lesch-Nyhan syndrome appears to offer clues to the developmental and neuronal defects found in other, diverse neurological disorders like Alzheimer's, Parkinson's and Huntington's diseases.

Study: Distinct behavior of proteins reflects common biochemical principles

Researchers from Case Western Reserve University School of Medicine have found unexpected similarities between proteins that were thought to be fundamentally different.

Researchers who contributed to field of medicine receive Keio Medical Science Prize

The 18th Keio Medical Science Prize has been awarded to Victor R. Ambros, PhD, professor of molecular medicine at the University of Massachusetts Medical School and the Silverman Chair in Natural Science; and Shigekazu Nagata, PhD, professor of medical chemistry in the Graduate School of Medicine at Kyoto University.

Regular five-meal pattern associated with reduced risk of obesity

A regular eating pattern may protect adolescents from obesity, according to a Finnish population-based study with more than 4,000 participants. When eating five meals - breakfast, lunch, dinner and two snacks - a day, even those with a genetic predisposition to obesity had no higher body mass index (BMI) than their controls.

New method to monitor activity of gene promoters during response to drug

When developing new drugs, monitoring cellular responses to candidate compounds is essential for assessing their efficacy and safety. Researchers from the RIKEN Center for Life Science Technologies report a new method to monitor and quantify the activity of gene promoters during the response to a drug, using the advanced gene expression analysis method CAGE followed by single-molecule sequencing.

Genetic discovery could take guesswork out of prescribing correct dose of drugs

The discovery of genetic differences affecting up to a third of the population could take the guesswork out of prescribing the correct dose of 25 percent of drugs currently on the market, researchers say.

Scientists unravel secrets of mechanism that snips our genes

Certain diseases such as cystic fibrosis and muscular dystrophy are linked to genetic mutations that damage the important biological process of rearranging gene sequences in pre-messenger RNA, a procedure called RNA splicing.

Researchers identify mutation in ITGA10 gene that causes chondrodysplasia in dog breeds

Professor Hannes Lohi's research group at the University of Helsinki and Folkhälsan Research Center has identified a mutation in ITGA10 gene, causing chondrodysplasia in two dog breeds, the Norwegian Elkhound and the Karelian Bear Dog.

Researchers show link between FTO gene and hip fracture in women

Australian researchers have demonstrated a strong association between the FTO (fat and obesity) gene and hip fracture in women. While the gene is already well known to affect diabetes and obesity, this is the first study to show that its high-risk variant can increase the risk of hip fracture by as much as 82%.

Small alteration in a brain gene contributes to risk for anxiety, depression and memory loss

Researchers at Weill Cornell Medical College have discovered why a tiny alteration in a brain gene, found in 20 percent of the population, contributes to the risk for anxiety, depression and memory loss.
