Treatments are lacking for sarcopenia, a debilitating age-related skeletal muscle wasting syndrome. We identifed increased amounts of 15-hydroxyprostaglandin dehydrogenase (15-PGDH), the prostaglandin E<sub>2</sub> (PGE<sub>2</sub>)-degrading enzyme, as a hallmark of aged tissues, including skeletal muscle. The consequent reduction in PGE<sub>2</sub> signaling contributed to muscle atrophy in aged mice and results from 15-PGDH-expressing myofibers and interstitial cells, such as macrophages, wit ...[more]
