Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

...chers identified nearly 200 genes likely to be key players in determining differences among primate species. These include genes involved in hair formation, immune response, membrane proteins and sperm-egg fusion. Many of these genes are located in areas of the primate genome that have been subject to duplic...

Brown cancer biologists identify major player in cell growth

... family of gene-regulating proteins that are major players in embryonic and cancer development, seemed obvious culprits. Rosmarin, a hematologist-oncologist, studies one member of the Ets family called GABP. This transcription factor helps make a variety of cells, including white blood cells. If those cells ...

Action video games sharpen vision 20 percent

...the University of Rochester. "After just 30 hours, players showed a substantial increase in the spatial resol...ter about a month of near-daily gaming, the Tetris players showed no improvement on the test, but the Unreal Tournament players could tell which way the "T" wa...

In obesity, brain becomes 'unaware' of fat

...ade.?The researchers demonstrated that those later players in the leptin pathway remained ready for action. Indeed, the downstream factors were actually found to be hypersensitive to stimulation. “Previous studies have suggested that SOCS-3 is a negative regulator of leptin,?Cowley said. “As animals becom...

Row over study puts Korea's scientific community under scrutiny again

... fertility specialist and one of the most powerful players in the country's struggle for biotech supremacy, writes journalist Jonathan Gornall. It is also threatening to disrupt Korea's efforts to recover scientific credibility in the wake of the recent scandal over Woo-Sok Hwang's stem cell research. Dr ...

BMI not accurate indicator of body fat

...ss, said Ode. "A previous study of NFL football players found that a large percentage of them ?around 60 percent ?were considered obese," he said. "But when you look at an athlete like that, you see that in many cases he is not obese. Many athletes have huge BMIs because of muscle mass, but in many cases ...

Herpes infection may be symbiotic, help beat back some bacteria

... viruses. "We have a good feel for who the main players are in this protective effect, but we need further research to better understand the exact mechanisms that underlie the process," Virgin says. He suspects that the virus may be prompting the immune system to produce more interferon gamma to keep i...

Slowing the racing heart

...cium and potassium channels that we know to be key players in the generation and regulation of the pacemaker activity," said Ke. "Although adrenaline and other mechanisms that accelerate the heart rate have been well studied, mechanisms that might act as a brake are poorly understood," said Solaro. "Id...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

... more useful it can be. "Insects are the major players in almost every ecosystem on the planet, so we need to know as much as we can about them." ...

Does amateur boxing cause brain damage?

... said Hietala. The study was extended to soccer players heading the ball repeatedly from long and high goal kicks. No increased levels of biochemical markers for brain damage in cerebrospinal fluid were found. "This data shows headings in soccer is not associated with any neurochemical evidence of brain d...

For many insects, winter survival is in the genes

...At this point, the findings broaden our palette of players that contribute to cold tolerance in insects." He said the next step is to figure out the unique functions of each heat-shock protein. "We assume it's not simply redundancy in the system, but that each protein makes a unique contribution someho...

Breakthrough developments in rheumatoid arthritis reported

...gle nucleotide polymorphisms, or SNPs, to identify players that have fallen under the radar of older methods. The group has discovered another signaling molecule that seems to increase a person’s risk for rheumatoid arthritis by 30 percent. (The paper reporting the gene is in press.) In collaborations w...
