Study helps explain why 'survival gap' persists for African-Americans A team of scientists at Johns Hopkins and in Texas has identified a handful of genetic mutations in black Americans, in addition to some chemical alterations affecting gene activity, which may help explain why the death rate among African-Americans from the most common form of head and neck cancer continues to hover some 18 percent higher above the death rate of whites with the same cancer. The so-called survival gap...

Certain genetic alterations to the PAX gene family may be responsible for survival disparities seen between African-American and non-Latino white men with head and neck cancer, according to results presented here at the Sixth AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held Dec. 6-9. "During the last 30 years, the overall five-year relative survival rates for head and neck squamous cell carcinoma (HNSCC) have...

Mindfulness Meditation Found To Result In Gene Expression Changes

redOrbit Staff & Wire Reports – Your Universe Online While there have been multiple scientific studies providing evidence that meditation can have a positive influence on a person’s health, new research appearing in the journal Psychoneuroendocrinology suggests there may be an actual biological trigger for these therapeutic effects. Researchers from the University of Wisconsin-Madison, along with colleagues from France and Spain, report they have discovered the first evidence...

Acquisition of lunasin technology triggers sales growth and increase in new distributorships CHESTERFIELD, MO (PRWEB) November 27, 2013 Reliv International, Inc. (NASDAQ: RELV), a maker of nutritional supplements that promote optimal health, today attributed much of the company’s recent sales growth to Reliv bringing the science of nutritional epigenetics to the marketplace. “In the past year we’ve positioned ourselves as the industry leader in this emerging field,” said Ryan...

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...
