摘要
Liver kinase B1 (Lkb1), also named as Serine/Threonine protein kinase 11 (STK11), is a serine/threonine kinase that plays crucial roles in various cellular processes including cell survival, cell division, cellular polarity, cell growth, cell differentiation, and cell metabolism. In metabolic tissues, Lkb1 regulates glucose homeostasis and energy metabolism through phosphorylating and activating the AMPK subfamily proteins. In skeletal muscle, Lkb1 affects muscle development and postnatal growth, lipid and fatty acid oxidation, glucose metabolism, and insulin sensitivity. Recently, the regulatory roles of Lkb1 in regulating division, self-renew, proliferation, and differentiation of skeletal muscle progenitor cells have been reported. In this review, we discuss the roles of Lkb1 in regulating skeletal muscle progenitor cell homeostasis and skeletal muscle development and metabolism.
