Finding the kinases that power brown fat

Obesity and its associated health risks are a critical and growing problem. Unlike white adipocytes, which store energy, brown adipocytes dissipate energy in the form of heat. Expansion or activation of brown fat has been proposed as a strategy to combat obesity. Using high-throughput analysis that combined RNA interference with pharmacological inhibitors, Perdikari et al. identified kinases that affected brown adipocyte proliferation, differentiation, or formation (when these cells acquire the ability to dissipate energy as heat). Of the 190 brown fat–regulating kinases, they investigated in detail the role of AMPK in promoting the formation of brown adipocytes. Their results highlight kinases that could be therapeutically targeted to enhance the development and function of brown fat.
