Gary Ruvkun
American geneticist / From Wikipedia, the free encyclopedia
Gary Bruce Ruvkun (born March 1952, Berkeley, California)[1] is an American molecular biologist at Massachusetts General Hospital and professor of genetics at Harvard Medical School in Boston.[2] Ruvkun discovered the mechanism by which lin-4, the first microRNA (miRNA) discovered by Victor Ambros, regulates the translation of target messenger RNAs via imperfect base-pairing to those targets, and discovered the second miRNA, let-7, and that it is conserved across animal phylogeny, including in humans. These miRNA discoveries revealed a new world of RNA regulation at an unprecedented small size scale, and the mechanism of that regulation. Ruvkun also discovered many features of insulin-like signaling in the regulation of aging and metabolism. He was elected a Member of the American Philosophical Society in 2019.
