The Hippo Signaling Pathway in the Regulation of Skeletal Muscle Mass and Function.

The Hippo signaling pathway regulates the activity of the proteins Yes-associated protein (Yap) and transcriptional co-activator with PDZ-binding motif (Taz) to control tissue growth in many different cell types. Previously, we demonstrated that Yap is a critical regulator of skeletal muscle mass. We hypothesize that alterations in Yap and Taz activity modulate the anabolic adaptations of skeletal muscle to resistance exercise.
