Biologists identify a new clue into cellular aging

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy portion of an individual's life span can be extended, it may delay the onset of certain age-related diseases. In the search to understand these molecular processes, researchers at the University of Massachusetts Medical School have uncovered an important new DAF-16 isoform - DAF-16d/f - that collaborates with other DAF-16 protein isoforms to regulate longevity.
