Abstract:<p>Besides the secretion of fatty acids, lipolytic stimulation of adipocytes results in the secretion of triglyceride-rich extracellular vesicle (AdEVs) and some free proteins (e.g., Fatty Acid Binding Protein 4) that in sum affect adipose homeostasis as well as the development of metabolic disease. At the mechanistic level, lipolytic signals activate p53 in an ATGL-dependent manner and pharmacologic inhibition of p53 attenuates AdEV protein and FABP4 secretion. Mass spectrometry analyses of the lipolyti… 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.
