The CBS Evening News (5/9, story 3, 2:05, Pelley, 5.58M) reported that in a mouse study, researchers found a hormone that may be a "fountain of youth" for heart failure.
USA Today (5/9, Vergano, 1.71M) reports that study author Richard Lee of Brigham and Women's Hospital in Boston, said, "We think this is something that we can really look at very carefully for the form of heart failure that occurs in the elderly."
On its website, CBS News (5/10) reports that researchers "honed in on a hormone called GDF-11, which declines with age in mice."
On its website, FOX News (5/10, Woerner) reports that investigators "injected GDF-11 into the blood streams of older mice in order to increase their GDF-11 levels to match the levels found in younger mice" After about one month, the investigators looked at "the hearts of the older mice, which had previously shown thickened walls similar to those in older humans." The investigators "found that the thickening had reversed, and the hearts of the older mice now looked almost identical to those of the younger mice."
The Boston Globe (5/10, Johnson, 250K) reports that the scientists "hope that the discovery will lay a foundation for a new approach to therapy for a common form of heart failure that strikes elderly people, although much more research is needed before it could be tested in people."
