    ..Albert et al. (2014) demonstrate that the lack of hormone-sensitive lipase, a member of the enzyme trio that catabolizes fat, has pronounced effects on lipid metabolism, glucose homeostasis, and cell signaling in humans. ..

    ..These results argue for the existence of an adaptive interdependence between lipolysis and lipid synthesis. Pharmacological inhibition of ATGL may prove useful to prevent HFD-induced obesity and insulin resistance. ..

    ..We conclude that G0S2 acts as a potent ATGL inhibitor in the heart modulating cardiac substrate utilization by regulating cardiac lipolysis. ..

    ..In summary, our data point to a hitherto unrecognized link between proteasomal function, PPARα signaling and cardiovascular disease. ..

    ..This review focuses on the structure, function, and regulation of lipolytic enzymes with a special emphasis on ATGL. ..

    ..Upregulation of soluble guanylate cyclase and cardiac tetrahydrobiopterin might be regarded as counterregulatory mechanisms in cardiac ATGL deficiency. ..

    ..Therefore, we suggest that miR-124a may be involved in the regulation of several cellular and organismal metabolic parameters, including lipid storage and plasma FA concentration. ..
