role of transcription factor E3 (TFE3), a bHLH transcription factor, in immunology and cancer has been well characterized. Recently, we reported that TFE3 activates hepatic IRS-2 and hexokinase, participates in insulin signaling, and ameliorates diabetes. However, the effects of TFE3 in other organs are poorly understood. Herein, we examined the effects of TFE3 on skeletal muscle, an important organ involved in glucose metabolism. We generated transgenic mice that selectively express TFE3 in skeletal muscles.…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
