Western blot analysis with a phosphospecific antibody of protein samples prepared form three control aortas (Ctl-Ao, lanes 1–3) and mesenteric arteries (Clt-Mes, lanes 4–6), and three angiotensin II-treated aortas (Ang-Ao, lanes 7–9) and mesenteric arteries (Ang-Mes, lanes 10–12). The bar chart represents the mean optical density (O.D.) of the three experiments for both ERK-1 (p44^mapk) and ERK-2 (p42^mapk) in control (open bars) and Ang II-treated animals (filled bars). * P < 0.05 vs Ctl; (unpaired t-test).
