Blocking 15-PGDH May Improve Muscle Repair Reduced by Weight Loss from GLP1-Receptor Agonists

Updated

Abstract

GLP-1 receptor agonists like semaglutide may cause significant loss of muscle mass in obesity models.

  • Semaglutide treatment is associated with decreased skeletal muscle mass in mice on a high-fat diet.
  • Despite the loss of muscle mass, contractile function remains intact with semaglutide use.
  • Muscle regeneration and strength recovery following injury are impaired by semaglutide treatment.
  • This impairment in muscle recovery is linked to reduced function of muscle stem cells.
  • Co-treatment with an inhibitor of a specific enzyme boosts muscle mass and improves regeneration when combined with semaglutide.
