Fig. 7From: Mechanical stretching of the pulmonary vein mediates pulmonary hypertension due to left heart disease by regulating SAC/MAPK pathway and the expression of IL-6 and TNF-αa. The protein expression levels of p-p38/p38 in the pulmonary veins of sham and PH-LHD model were assessed by western blotting analysis. *P < 0.05 vs. S1, # P < 0.05 vs. M1. b. PH-LHD model rats were treated with SB203580, SP600125, U0126 and streptomycin. *P < 0.05 vs. the M2Back to article page
