Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) in Barcelona, Spain, have studied the role of a peculiar class of small non-coding RNAs that are mainly expressed in the human male germline. Whereas messenger RNAs transmit the genetic information required for protein synthesis, non-coding RNAs are functional molecules that are never translated into proteins and have important roles in diverse cellular processes. In human spermatozoa, these tiny RNAs are epigenetically...

Findings have implications for oncology, diabetes drug development Drugs that inhibit the activity of enzymes called histone deacetylases (HDACs) are being widely developed for treating cancer and other diseases, with two already on the market. Researchers at the Perelman School of Medicine, University of Pennsylvania, show that a major HDAC still functions in mice even when its enzyme activity is abolished, suggesting that the beneficial effects of HDAC inhibitors may not actually be...

Promiscuous Female Mice Have Sexier Sons

University of Utah Males make more pheromone if mama had access to many mates University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, but smelling sexier shortens their lives. "If your sons are particularly sexy, and mate more than they would otherwise, it's helping get your genes more efficiently into the next generation,"...

A study published this week in PLOS Medicine suggests that epigenetic modification of the HAND2 gene plays a critical role in the development of endometrial cancer. HAND2 is active in the healthy endometrium (the tissue lining the uterus) where it antagonizes the growth-inducing effects of estrogen. By contrast, in more than 90% of endometrial cancers, the gene has undergone hypermethylation, an epigenetic modification that doesn't change its DNA sequence but renders it inactive. Martin...

New studies show life events influence genes important for memory and drug use New human and animal research released today demonstrates how experiences impact genes that influence behavior and health. Today's studies, presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, provide new insights into how experience might produce long-term brain changes in behaviors like drug addiction...

From a new study in Biological Psychiatry Children of survivors of extremely stressful life events face adjustment challenges of their own, as has been most carefully studied among the children of Nazi Death Camp survivors. This "intergenerational" transmission of stress response has been studied predominately from the psychological perspective. However, recent research points to biological contributions as well. Indeed, a new study just published in Biological Psychiatry demonstrates...

Deleting One Gene In Fungus Reveals New Compounds With Antibiotic Potential
2013-11-01 08:42:09

Oregon State University Researchers at Oregon State University have discovered that one gene in a common fungus acts as a master regulator, and deleting it has opened access to a wealth of new compounds that have never before been studied – with the potential to identify new antibiotics. The finding was announced today in the journal PLOS Genetics, in research supported by the National Institutes of Health and the American Cancer Society. Scientists succeeded in flipping a genetic...

Veil Of Ignorance Is Sometimes Bliss

Washington University in St. Louis A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals — and even among genes For the Oct. 16 issue of Biology Letters, a special issue commemorating the 50th anniversary of W.D. Hamilton’s famous paper on kin selection, two Washington University in St. Louis biologists contributed an article describing intriguing exceptions to one of his predictions. The basic idea of...
