Abstract:
Objective To observe nitric oxide synthase (NOS) activity and the expresssion of inducible NOS (iNOS) mRNA in cultured calf aortic endothelial cells treated with various concentrations of insulin. Methods Cultured calf aortic endothelial cells were incubated with different concentrations of insulin for 24 h. NOS activity was determined by colorimetry and iNOS mRNA was measured by semi-quantitative RT-PCR. Results NOS activity and the expression of mRNA in calf aortic endothelial cells at pharmacological concentration (10 -7 mol/L) of insulin were significantly increased than those at physiological concentration (10 -10 mol/L) of insulin (P
