• mice fed a high fat diet exhibit impaired insulin-induced ET-1-dependent vasoconstriction compared with wild-type mice
|
• mice exhibit impaired high fat-diet-induced impairment in insulin-induced relaxation that is reversed to vasoconstriction compared with wild-type mice
|
• during contractions to the prostaglandin H2 analog U46619, the magnitude of insulin-induce relaxation is greater than in wild-type mice
• however, maximal relaxation response to supraphysiological doses of insulin is normal
