Abstract:Caffeic acid phenethyl ester (CAPE) has recently been shown to potently stimulate glucose uptake in cultured skeletal muscle cells through the AMPK pathway and therefore to have anti-diabetic potential. We report here that CAPE increases glucose uptake in C2C12 muscle cells by 225+/-21% at 50 microM, and that activation of AMPK is a consequence of the metabolic stress resulting from an uncoupling-type disruption of mitochondrial function (complete uncoupling at 50 microM). We also observe that the therapeutic …
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 of Drug Abuse of the National Institutes of Health.
