Research Abstract

Expression and role of AMPK-related kinase, ARK5, in skeletal muscle cells and adipocytes were analyzed. In skeletal muscle cell, ARK5 promotes insulin-induced glucose uptake. Addition to muscular ARK5, I showed that ARK5 expressed in white adipose tissue (WAT) of obese animals and that promotes WAT hypertrophy and inflammation via its cell survival promotion-activity.
