Areas of Interest
The Inoki lab focuses on investigating the molecular mechanisms of cellular energy sensing and the roles of protein kinases such as mechanistic target of rapamycin (mTOR) and AMP-activated kinase in the regulation of cell growth, proliferation and survival control. Dys-regulation of mTOR and AMPK signaling has been implicated in a wide array of human health problems including cancer, diabetes, neurodegenerative diseases, and aging. Our group takes biochemical approaches to identify novel interacting proteins and signal transduction to expand our understandings of cellular energy sensing mechanism. Then, we take genetic approaches to clarify our biochemical observations and to seek pathophysiological relevance in mouse models. Our main goal is to elucidate the molecular mechanisms underlying dys-regulation of mTOR and AMPK pathway-associated metabolic disorders and cancer development.
