A protein called Sestrin might be responsible for many of the benefits of a good workout. Michigan Medicine researchers studying a class of naturally occurring protein called Sestrin have found that it can mimic many of exercise’s effects in flies and mice. The findings could eventually help scientists combat muscle wasting due to aging and other causes.

“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” said Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology. Kim, working with professor Jun Hee Lee, Ph.D...

Michigan Medicine researchers studying a class of naturally occurring protein called Sestrin have found that it can mimic many of exercise’s effects in flies and mice. The findings could eventually help scientists combat muscle wasting due to aging and other causes.

“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” said Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology. Kim, working with professor Jun Hee Lee, Ph.D. and a team of researchers wanted to know more about the protein’s apparent link to exercise. Their first step was to encourage a bunch of flies to work out.

Taking advantage of Drosophila flies’ normal instinct to climb up and out of a test tube, their collaborators Robert Wess...
