CJF induces a concentration- and time-dependent phosphorylation of eNOS at Ser1177 in endothelial cells. Cells were exposed to CJF for the indicated concentrations and times at 37°C. Thereafter, the level of p-eNOS was determined by Western blot analysis. (a) Representative immunoblots and (b) corresponding cumulative data for time-dependent phosphorylation of eNOS. Results are shown as means ± SEM (-4). , , , significant difference versus control.
