Figure 6.

Effects of TGF-β1, SB431542, SB203580 and OMT on p38 mitogen-activated protein kinase phosphorylation in CFBs. Representative western blot images and quantification are shown. Data are expressed as the mean expression relative to control ± standard error of the mean (n=3). ^##P<0.01 vs. control; **P<0.01 vs. TGF-β1 group. TGF-β1, transforming growth factor-β1; OMT, oxymatrine; CFBs, cardiac fibroblasts; p-, phosphorylated; p38, p38 mitogen-activated protein kinase; L, low-dose; M, medium-dose; H, high-dose.
