The VCCC was incubated with the gap junction inhibitor 18-GA (50µM) for 30 minutes before adding bradykinin (BK, 10µM, n=4) (A) or phenylephrine (PE, 50µM, n=3) (B). Timepoints indicate the minutes after stimulation. Cellular fractions were harvested for western blotting and the ratio of eNOS S 1177 to total eNOS is presented. All error bars represent SEM. In A and B, * indicates p<0.05
