WebApr 12, 2024 · To inhibit CES2 activity, cells were incubated with 10 µM Loperamide (Sigma-Aldrich) or DMSO as control for 48 h. For insulin signaling, cells were incubated with depleting media (DMEM low glucose) for 2 h followed by a 30 min treatment with 10 µg/ml insulin in depleting media. WebDec 1, 2006 · Previous studies suggest that insulin can inhibit hepatic glucose production by both direct and indirect actions. The indirect effects include inhibition of glucagon secretion, reduction in plasma nonesterified fatty acid levels, reduction of the amount of gluconeogenic precursor supplied to the liver, and change in neural input to the liver.
