Early Warning System For Breast Cancer

...f RhoC. But in cancerous non-muscle cells, RhoC is key to the structural changes that give a cell the ability to break off from a tumor, float through the body in the bloodstream, and take hold in a satellite location - in other words, to metastasize. Researchers developed the test based on their rese...

Stem Cells Have Few Mutations

...pread research on embryonic stem cell mutations, a key problem in learning how to use the cells for therapy. ``Our study defines one of the problems that can be screened for in embryonic stem cells,'' said Tischfield. The mutation found in the cells ``does not present an insurmountable problem'' in devel...

Mutating viruses helps produce antibodies

...might switch their locks to prevent someone with a key from getting in. "In the world of microbial biowarfare, standing still in the face of a ferocious viral attack is a recipe for disaster," explained microbiologist Graham Hatfull of the University of Pittsburgh. Bordatella can switch between two dist...

Decrease of 'Hunger Hormone' after Obesity Surgery

...that the hormone contributes to hunger and plays a key role in the long-term regulation of body weight, the study authors note. They concluded that their finding showed significant reduction of ghrelin levels after gastric bypass and thereby suggests that suppression of ghrelin can be studied as a pote...

Birth weight may be influenced by genes

...ental factors like maternal smoking certainly play key roles in birth weight. But the knowledge that genes also help determine a newborn's weight could have implications for preventing low birth weight, Ha said, since the effects of environmental factors may vary depending on a person's genes....

DNA transcription to be focused

Altitude sickness connected to genes

... endothelial nitric oxide synthase (eNOS) gene, is key in the role of releasing nitric oxide in the blood. The researchers compared the genetic sequence of eNOS in climbers who had been affected by HAPE to those who had not been affected. They found 9.8 percent of the non-HAPE group had a genetic variati...
