Our results suggest that arsenite can potentiate EDHF - type relaxations via a mechanism that is dependent on hydrogen peroxide , thus demonstrating that dismutation of the superoxide anion generated by NADPH oxidase can potentially offset loss of NO bioavailability under conditions of reduced eNOS activity .
