Obesity is associated with mitochondrial dysfunction and chronic metabolic derailment. Cho et al. report that elevated adipose expression of the Hippo kinases STK3 and STK4 (STK3/4) in obesity and type 2 diabetes decreases the mass and oxidative capacity of adipocyte mitochondria. Genetic or pharmacological inhibition of STK3/4 restores mitochondrial mass and function in adipocytes and improves glucose homeostasis in mice with diet-induced obesity. These findings support STK3/4 as new targets for obesity-related diseases.
