Oncoproteins destroy vital tumor-suppressorTwo previously unconnected cancer-promoting proteins team up to ambush a critical tumor suppressor by evicting it from the cell's nucleus and then marking it for death by a protein-shredding mechanism, a team led by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Feb. 10 issue of Nature Cell Biology.

Sleep problems may affect a person's dietSleep problems can influence a persons diet. Those who dont get enough sleep are less likely to cook their own meals and, instead, opt to eat fast food.
