OBJECTIVE Atherosclerotic cardiovascular disease is the leading cause of death among people with diabetes. Generation of oxidized LDLs and reduced nitric oxide (NO) availability because of endothelial NO synthase (eNOS) dysfunction are critical events in atherosclerotic plaque formation. Biochemical mechanism leading from hyperglycemia to oxLDL formation(More)
OBJECTIVE Nicotinamide rescues β-cell damage and diabetes in rodents, but a large-scale clinical trial failed to show the benefit of nicotinamide in the prevention of type 1 diabetes. Recent studies have shown that Sirt1 deacetylase, a putative protector of β-cells, is inhibited by nicotinamide. We investigated the effects of isonicotinamide, which is a(More)
In liver, glucose utilization and lipid synthesis are inextricably intertwined. When glucose availability exceeds its utilization, lipogenesis increases, leading to increased intrahepatic lipid content and lipoprotein secretion. Although the fate of three-carbon metabolites is largely determined by flux rate through the relevant enzymes, insulin plays a(More)
The pancreas and hypothalamus are critical for maintaining nutrient and energy homeostasis, and combined disorders in these organs account for the onset of the metabolic syndrome. Activating transcription factor 3 (ATF3) is an adaptive response transcription factor. The physiological role of ATF3 in the pancreas has been controversial, and its role in the(More)
