Scientists track stealth DNA elements in primate evolution

...ngutans, gibbons and siamangs. The AluYb subfamily accounts for approximately 40% of all human-specific Alu elements and is currently one of the most active Alu lineages in the human genome. Some AluYb elements are still actively mobilizing in the human genome, causing insertion mutations that have led to the...

New lifespan extension genes found

...genes in yeast. They found a gene called Hst2 that accounts for most of the difference. Deleting Hst2 and Sir2 blocked most of the beneficial effect of caloric restriction. When Hst2 was overexpressed, so that the gene was more active than normal, the yeast lived longer than normal. A third gene, Hst1, appea...

UCR biochemist goes to Washington with high-protein corn

...t widely produced feed grain in the United States, accounts for more than 90 percent of total value and production of feed grains in the country, with around 80 million acres of land planted with corn. Gallie's research on doubling the protein content of corn grain adds significant value to the crop, benefit...

No small feat: First ever gene therapy success for muscular dystrophy achieved

...And because CMD affects all muscles, an organ that accounts for 40 percent of body weight, gene therapy can only have real therapeutic benefit if it is able to reverse genetic defects in every cell of the body's 600 muscle groups. By using a miniature gene, similar in function to the one defective in CMD, an...

Computers close in on protein structure prediction

Stroke treatment a step closer after trial

...disability, affecting 100,000 people each year. It accounts for 6.5% of total NHS and social services expenditure and there are currently no treatments available. Stroke occurs when vessels supplying blood to the brain become blocked and the brain is starved of oxygen. A core area of the brain dies within mi...

University of Arizona plant scientists to unravel maize genome

...ops in the United States, and, together with rice, accounts for 70 percent of worldwide food production. The production of corn-based products with enhanced nutritional value that are safer and less allergenic than the foods we eat today will directly benefit consumers. Corn plants will also prove useful in p...

Compound from marine bacteria shows potential as multiple myeloma therapy

The most common manifestation of acute pharyngitis is sore throat. The main bacterial cause of sore throat and th...

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

... types of cancer to treat, advanced ovarian cancer accounts for approximately 26,000 new cases and 16,000 deaths in the U.S. each year. "Being able to identify the expression pattern of these genes from the original tumor sample [i.e. whether genes were 'turned on' or 'turned off'] provides us with valuable ...

Scientists fetch useful information from dog genome publications

Overfishing in inland waters reduces biodiversity and threatens health

...imbalance, since freshwater ecosystems are by some accounts more threatened than marine ecosystems. Fishing is a crucial source of livelihoods in developing nations, and in 2000 constituted an estimated 15.3 percent of human consumption of animal protein. About 1 billion people rely on fish as their primary ...

Researchers map of genetic variations implicated in disease

"Data generated by projects such as the MHC Haplotype Project will feed into the recently announced Wellcome Trust Case-Control Consortium," explained Professo...

Genetic and environmental influences on alcohol consumption among rhesus monkeys

"Additive genetic effects account for 20 percent of the total variation, leaving 20 percent of the variance attributable to 'residual environmental effects...

There's something fishy about human brain evolution

It's this baby fat, says Dr. Cunnane, that provided the physiological winning conditions for hominids' evolutionary brain expansion. And how were hominid babies able to p...
