Is there an ‘exercise pill’ in our future?

Suppressing production of the protein myostatin enhances muscle mass and leads to significant improvements in markers of heart and kidney health, according to a study conducted in mice. Joshua T. Butcher, PhD, a postdoctoral fellow at the Vascular Biology Center at Augusta University, will present the work at the American Physiological Society’s annual meeting during the Experimental Biology 2017 meeting, held April 22–26 in Chicago.

The researchers zeroed in on myostatin because it is known as a powerful inhibitor of skeletal muscle growth, meaning that people with more myostatin have less muscle mass and people with less myostatin have more muscle mass. Studies suggest obese people produce more myostatin, which makes it harder to exercise and harder to build muscle mass.
