Batting Practice in the Genome

Aug. 25, 2015 — In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But scientists have now found that spectator proteins ... read more

Genetic Overlapping in Multiple Autoimmune Diseases May Suggest Common Therapies

Aug. 24, 2015 — Scientists who analyzed the genes involved in 10 autoimmune diseases that begin in childhood have discovered 22 genome-wide signals shared by two or more diseases. These shared gene sites may reveal ... read more

Genetic Ancestry Partially Explains One Racial Sleep Difference

Aug. 21, 2015 — A new study clearly establishes a partial genetic basis underlying racial differences in slow-wave sleep, suggesting that it may be possible to develop sleep-related therapies that target specific ... read more

Aug. 21, 2015 — Scientists have revealed that weak doses of gamma radiation prolong the life of drosophila flies (fruit flies), and that the effect is stronger in females than in males. These findings could reveal ... read more

Aug. 21, 2015 — The dietary supplement alpha lipoic acid can stimulate telomerase, the enzyme that lengthens chromosomes' protective caps, with positive effects in a mouse model of atherosclerosis, scientists ... read more

Aug. 21, 2015 — Researchers have discovered how two important proofreader proteins know where to look for errors during DNA replication and how they work together to signal the body's repair ... read more

Aug. 21, 2015 — Many cells in our bodies present a small structure that looks like, and as a matter of fact works as an antenna, conveying to the cell information on the extracellular environment. They are called ... read more

Study Finds Genes Associated With Improved Survival for Pancreatic Cancer Patients

Aug. 20, 2015 — A new set of genes that can indicate improved survival after surgery for patients with pancreatic cancer has been identified by researchers. The study also showed that detection of circulating tumor ... read more

Researchers Suggest Approach to Fight Common Virus in Immunosuppressed Patients

Aug. 20, 2015 — New light has been shed on how adenovirus replicates in humans. The findings suggest that agents that enhance the Type I interferon signaling pathway could be useful to fight adenovirus infections in ... read more

Unique Genes in Khoe-San People May Lower Risk of Some Pregnancy Hazards

Aug. 20, 2015 — An unusual mutation in an immune system gene switches a receptor from one target molecule to another in Khoe-San people. It's the first known example of such a change, say researchers, and ... read more
