Figure 4. Involvement of MAPKs on angiotensin II-induced contraction.
Mesenteric arteries with intact endothelium from control and monosodium glutamate-induced obese rats were pretreated with PD 98059 (1 µM), a specific MEK/ERK1/2 inhibitor (A), SB-203580 (1 µM), a catalytic inhibitor for p38 MAPK (B), or SP 600125 (1 µM), an inhibitor of JNK (C) for 30 min and non-cumulative concentration–response curves to angiotensin II (ANG II) were obtained. Each point represents the mean ± SEM. *, P<0.05 vs. Control. #, P<0.05 vs. respective group in the absence of blockade. N = 6/group.
