More Than 40 New Genetic Links To Rheumatoid Arthritis Discovered
2013-12-26 08:06:07

redOrbit Staff & Wire Reports - Your Universe Online An international team of scientists has uncovered more than 40 new genes, pathways and cell types linked to an increased risk of rheumatoid arthritis, according to research published Wednesday in the online edition of the journal Nature. The study, which according to BBC News science correspondent Pallab Ghosh, is the largest genetic study ever completed, involving nearly 30,000 rheumatoid arthritis (RA) patients and more than...

Stress Gene Linked Heart Attacks
2013-12-19 12:03:34

Rebekah Eliason for redOrbit.com – Your Universe Online A new study from Duke reveals that the genetic trait responsible for predisposing some people to strong stress reactions may also cause the risk of heart attack or death to rise by 38 percent. This discovery provides a new biological explanation for why some people are inclined towards cardiovascular disease. Since in these cases the disease is linked to stress, the findings suggest that behavior modification and drug therapies...

The latest study was published online in Nature Genetics Coding variants in immune disease-related genes play only a small part in the overall genetic risk for psoriasis, according to a new study led by Anhui Medical University and BGI. This conclusion is strongly supported by their investigation on the contribution of functional coding variants to psoriasis in 21,309 Chinese individuals. In such a large-scale investigation, researchers only discovered two independent low-frequency...

Cucumber Genome Resequenced Revealing An Evolutionary Enigma
2013-10-21 04:42:19

redOrbit Staff & Wire Reports - Your Universe Online Large-scale, deep re-sequencing of 115 cucumbers worldwide has led to the creation of a genomic variation map for the vegetable that includes 3.6 million variants, an international team of scientists report in a new study. The authors, who hail from the Genome Centre of the Chinese Academy of Agricultural Sciences (CAAS), the Beijing Genomics Institute (BGI) and other institutions, have published their work in the online edition...

Genetic Variation Fuels Testicular Cancer
2013-10-11 04:33:32

Brett Smith for redOrbit.com - Your Universe Online Using a genomic analysis, a team of international researchers has identified a specific mutation responsible for a dramatic increase in the risk for testicular cancer. The mutation is a single-base change to the genetic code that affects the activity of the p53 protein that is responsible for regulating the activity of a large number of genes, including those responsible for protection from UV rays – according to the team’s report...

Findings likely to improve how patients are prescribed one in four clinically used 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. The scientists found two genetic variants that alter the activity level of an enzyme responsible for processing, or metabolizing, drugs ranging from the painkiller codeine to the breast cancer drug...

Japanese researchers have identified a mutation associated with a higher incidence of lung cancer in Japanese women who do not smoke, but better survival in lung cancer patients. In a study published today in the journal PLOS ONE, the team from the RIKEN Center for Life Science Technologies shows that a single nucleotide polymorphism (SNP) in a gene that protects cells from oxidative stress is found four times more frequently in women than in men. Lung cancer is the leading cause of...

Concealed within the vastness of the human genome, (comprised of some 3 billion base pairs), mutations are commonplace. While the majority of these appear to have neutral effect on human health, many others are associated with diseases and disease susceptibility. Reed Cartwright, a researcher at Arizona State University's Biodesign Institute, along with colleagues at ASU, Washington University and the Wellcome Trust Sanger Institute, Cambridge, UK, report on a new software tool known as...

Similar genetic variations occur in both overweight newborns and obese adults, a large study finds. The results will be presented Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco. "Our data suggest that adult obesity and newborn adiposity share, in part, a common genetic background," said study lead author Reeti Chawla, MD, fellow in pediatric endocrinology at Ann & Robert H. Lurie Children's Hospital of Chicago and the Northwestern University Feinberg School of...
