Non-insulin dependent diabetes mellitus (NIDDM) is a heterogeneous disease arising from metabolic defects in insulin secretion and insulin action. The inability of insulin to trigger full metabolic responses results in impaired glucose transport, which elicits compensatory hyperinsulinemia with increased lipogenesis. In order to identify the molecular defects responsible for insulin resistance, we have investigated three different model systems: the ability of sulfonylurea receptor (SUR) ligands to modify insulin regulated events in cultured rodent adipocytes; the ability of agouti and/or agouti related polypeptide (AGRP) to modify insulin regulated events; and the regulation of the activity and amount of the HNF-1a transcription …
