Protein that promotes cancer cell growth identified
LA JOLLA, Calif., July 24, 2009 Scientists at Burnham Institute for Medical Research (Burnham) have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade ...

Cellular self-eating promotes pancreatitis
To survive tough times, cells sometimes resort to a form of self-cannibalism called autophagy. But as Hashimoto et al. reveal, autophagy can have a down side, destroying the pancreas by prematurely activating a digestive enzyme.
In autophagy, a vesicle swallows a portion of cytoplasm and ferries...

Have a taste for fat? Yes! A sensor in the mouth promotes preference for fatty foods
The sense of taste informs the organism about the quality of ingested food. It comprises five sub-modalities that perceive sweet, salt, sour, bitter, and umami stimuli. The possibility for an additional taste modality directed to lipid has often been suggested because many animals exhibit a sponta...
Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leukemia Prognosis
The complex and life-sustaining series of steps by which hematopoietic stem cells (HSC) give rise to all of the body's red and white blood cells and platelets has now been discovered to depend in large part on a single protein called Mcl-1. This finding, from an investigator at St. Jude Children's ...
