Oops! Anti-Obesity Drug Now In Clinical Trials May Cause Rapid Bone Loss

An endocrine hormone used in clinical trials as an anti-obesity and anti-diabetes drug causes significant and rapid bone loss in mice, raising concerns about its safe use, UT Southwestern Medical Center researchers have shown.

The hormone, fibroblast growth factor 21 (FGF21), promotes bone loss by enhancing the activity of a protein that stimulates fat cells but inhibits bone cells, researchers report in a study available online in Proceedings of the National Academy of Sciences.

"This hormone is a very potent regulator of bone mass," said Dr. Yihong Wan, assistant professor of pharmacology and senior author of the study. "When we oversupply FGF21 in mice, it results in substantial bone loss."
