The finding came from the first comprehensive study of fat-controlling hormones (known as lipokines) in exercise. “This is a whole new area in research on exercise metabolism, and we seem to have found another mechanism by which exercise can have beneficial effects,” says Laurie Goodyear, Ph.D., Head of Joslin’s Section on Integrative Physiology and Metabolism and senior author on a report on the work published in Cell Metabolism.

Experiments in both humans and mice have shown that levels of one lipokine, with the unwieldy name of 12,13-diHOME, climb significantly in exercise, unlike the levels of other lipokines analyzed.

The study followed up on research published last year in joint work with the lab of Joslin’s Yu-Hua Tseng, Ph.D. This collaboration explored the release of lipokines from brown fat, which can burn energy in people or other mammals exposed to cold. In both humans and mice, the researchers demonstrated that the 12,13-diHome molecule was released from brown fat during cold exposure and offered beneficial metabolic effects.
