Starvation hormone markedly extends mouse life span, researchers report

DALLAS – Oct. 16, 2012 – A study by UT Southwestern Medical Center researchers finds that a starvation hormone markedly extends life span in mice without the need for calorie restriction.
FGF21 seems to provide its health benefits by increasing insulin sensitivity and blocking the growth hormone/insulin-like growth factor-1 signaling pathway.  When too abundant, growth hormone can contribute to insulin resistance, cancer, and other diseases, the researchers said.
