Metabolism:  A is for adipokine

Deborah M. Muoio1 & Christopher B. Newgard1

Top

Adipokines are hormones that signal changes in fatty-tissue mass and energy status so as to control fuel usage. A fat-derived adipokine that binds to vitamin A provides a new link between obesity and insulin resistance.

The worldwide epidemic of obesity has been accompanied by a surge in the incidence of diabetes1. Normally, control of blood glucose levels depends on the efficient action of insulin, which stimulates uptake of glucose from the blood and slows its output from the liver.
