How dietary restriction slows down aging

How dietary restriction slows down aging
University of Washington researchers have uncovered details about the mechanisms through which dietary restriction slows the aging process. Working in yeast cells, the scientists have linked ribosomes, the protein-making factories in living cells, and Gcn4, a specialized protein that aids in the expression of genetic information, to the pathways correlation to dietary response and aging. The study, which was led by UW faculty members Brian........Go to the Research news blog (Added on 4/17/2008 8:14:05 PM)

Drug compound leads to death of ovarian cancer cells
In a discovery that may be useful for maintaining remission in chemo-resistant ovary cancer, Yale researchers report that pre-clinical studies have shown the drug compound NV-128 can induce the death of ovary cancer cells by halting the activation of a protein pathway called mTOR.
