A molecular clue to longevity
Understanding the processes that regulate aging is crucial to potentially increasing longevity and enhancing quality of life. Using the budding yeast, Saccharomyces cerevisiae (S. cerevisiae), Christopher Lord, Ph.D., Ophir Ospovat and Susan Wente, Ph.D., demonstrated that accumulation of tRNA (transfer RNA) in the nucleus increased replicative life span. These results were published this month in the journal RNA.
