Sci. Aging Knowl. Environ., 28 July 2004 NEWS SYNTHESISGrowing PainsGrowth hormone therapy turns back the years, say its advocates, but animal studies suggest that a dearth of the hormone--not a surplus--extends life. Clinicians and lab researchers are striving to resolve the molecule's apparently conflicting powersR. John Davenport http://sageke.sciencemag.org/cgi/content/full/2004/30/ns5Abstract: Widely touted as a panacea against aging, growth hormone does provide some benefits. The molecule helps the elderly build muscle and burn fat, according to some clinical studies, yet no one knows whether long-term therapy is safe--or if it improves a person's life. Furthermore, laboratory work suggests that less growth hormone is the secret to exceptional longevity. Researchers are sorting through the data and devising new approaches to understand the two sides of this molecule. Citation: R. J. Davenport, Growing Pains. Sci. Aging Knowl.
