Abstract:Evidence is now revealed that the cytotoxic effect caused by elevated levels of plasma glucose and free fatty acids, also called as glucolipotoxicity, is particularly harmful for pancreatic β-cell. In fact, the mammalian Ste20-like kinase 1 (MST1) can mediate glucolipotoxicity-induced β-cell damages by degradation of pancreatic and duodenal homeobox 1 (PDX-1), which is known to play an essential role in maintaining β-cell function and survival. Interestingly, the activation of the pluripotency-related microRNA… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
