AMPK inhibition attenuates eNOS Ser635 phosphorylation in ECs. A, BAECs were pretreated with compound C at 20 μmol/L for 30 minutes before undergoing 30-minute treatment with laminar shear stress at 12 dyn/cm2, atorvastatin at 1 μmol/L, or adiponectin at 30 μg/mL. In B, HUVECs were transfected with AMPKα1 siRNA, AMPKα2 siRNA, or scramble RNA (10 nmol/L) before atorvastatin treatment. Phosphorylation of eNOS Ser635, AMPK Thr172, and ACC Ser79 was revealed by Western blotting. The bar graphs represent the densitometry analyses of Western blotting as means±SD of 3 or 4 independent experiments. *P<0.05 between groups as indicated.
