JNK activity is involved in actin remodeling processes during PEITC treatment. (a) The upper panel displays phase-contrast images and confocal analysis of HUVECs treated with (A, E) 0.01% DMSO (control), (B, F) 10 μM of SP600125 (JNK inhibitor) for 1 h (C, G), and 10 μM of PEITC for 2 h and (D, H) pretreated with 10 μM of SP600125 1 h before PEITC administration. Scale bars: d = 15 μm and h = 5 μm. (b) The levels of GTP-bound Rac1, phospho-JNK, and phospho-c-Jun in lysates of HUVECs, pretreated or not with 10 μM of SP600125 for 1 h, were analyzed in the presence/absence of 10 μM PEITC stimulation for 2 h. The left bar graphs depict densitometric analysis of Rac1 activity, phospho-JNK, and phospho-c-JUN levels. Results were obtained from at least two independent experiments and are expressed as the mean ± SEM. ∗P < 0.05, #P < 0.01, §P < 0.001, statistically significant differences, compared to DMSO-treated cells (C), were calculated by Student's t-test for unpaired data.
