mTOR and the Age-Related Decline in Stem Cell Activity

As a companion piece to an earlier post on the relationship between the mechanistic target of rapamycin (mTOR) gene and cellular senescence in aging, you might take a look at the research here that investigates the relationship between mTOR and the characteristic decline in stem cell activity that occurs with advancing age. In addition to the large body of research focused on insulin and growth hormone metabolism, work on mTOR is among the most active areas of study resulting from investigations of calorie restriction.
