We love skeletal muscle.

The Molecular Muscle Mass Regulation Laboratory at the University of Arkansas uses molecular biology techniques to study muscle mass regulation in the contexts of exercise adaptation, aging, and disease.

Specifically, the M3R Lab is interested in:

  • Skeletal muscle epigenetics
  • Muscle stem cell (satellite cell) contributions to exercise adaptation and aging
  • Single cell and nucleus approaches to studying muscle biology (primarily in adult muscle)
  • The role of microRNAs (miRNAs) in muscle health
  • The cellular and molecular bases of “muscle memory”
