Scientists at the Buck Institute for Research on Aging and the University of Washington have identified 238 genes that, when removed, increase the replicative lifespan of S. cerevisiae yeast cells. This is the first time 189 of these genes have been linked to aging. These results provide new genomic targets that could eventually be used… Continue reading Mapping the Genes That Increase Lifespan

One Molecule, Many Illnesses
Researchers have identified what seems to be a molecular “switch” that controls inflammatory processes linked to a number of conditions including muscle atrophy and Alzheimer’s disease. The study, led by Massachusetts General Hospital (MGH) investigators, found that the action of the signaling molecule, nitric oxide, on the protein SIRT1, appears to be necessary for the… Continue reading One Molecule, Many Illnesses
