Contribution of AP-1 to the ET-1-induced oxidative stress and COX-2 expression in VSMC from hypertensive rats. Effect of SP600125 (SP, 20 µM) on NOX-1 mRNA levels (a), NADPH oxidase activity (b) and COX-2 protein expression (c) and mRNA levels (d) induced by ET-1 (0.1 µM, 1 h). *P < 0.05 vs control (Ctrl) and #P < 0.05 vs ET-1 by Student's t-test. (e) Time-course of ET-1 (0.1 µM)-induced p-JNK1/2 protein expression in VSMC from SHR; *P < 0.05 vs control (0´) by one-way ANOVA. A representative blot is shown in the upper panel; lower panel shows reblotting of upper panel with JNK2 antibody. (f) Effect of ET-1 (0.1 µM, 1 h) on c-jun mRNA levels. Statistical analysis by Student's t-test. n denotes number of experiments. Full-length blots are presented in Supplementary Fig. S4.
