Tumor-fighter throttles life-extending protein SIRT1

Mitch Leslie

Abstract: Cancer and long life seem mutually exclusive, but a new study suggests that a life-extending enzyme also hikes tumor risk. Researchers knew that the enzyme, SIRT1, stalls a pathway that causes abnormal cells to commit suicide. The new work pinpoints a protein that normally keeps SIRT1 under control, but whose production wanes with age.
