The effects of protease inhibitors on basal and insulin-stimulated lipid metabolism, insulin binding, and signaling

The objective of our research was to investigate the effects of the protease inhibitors ritonavir, saquinavir, and indinavir on triglyceride synthesis, lipolysis, insulin binding, and signaling in differentiating 3T3 L1 pre-adipocytes. Saquinavir, ritonavir, and indinavir all stimulated triglyceride (111104) synthesis. Additionally, all concentrations of protease inhibitors employed (i.e., 0.1 μM to 10 μM) significantly decreased insulin-stimulated TG synthesis. No effects of any of the protease inhibitors were observed either on basal lipolysis or after stimulation of lipolysis with 100 nM noradrenaline. Specific 125I-insulin binding was observed to be decreased by exposure to all the protease inhibitors throughout the period of adipocyte phenotype development. This was mediated by indinavir through and on with (i.e., of differentiating insulin was and to be decreased in the with The protease effects on basal TG decreased insulin-stimulated TG concentrations of protease effects be to decreased insulin binding The objective of our research was to investigate the effects of the protease inhibitors ritonavir, saquinavir, and indinavir on triglyceride synthesis, lipolysis, insulin binding, and signaling in differentiating 3T3 L1 pre-adipocytes.
