Fig. 5From: TGF-β1/SMOC2/AKT and ERK axis regulates proliferation, migration, and fibroblast to myofibroblast transformation in lung fibroblast, contributing with the asthma progressionInhibition of AKT and ERK pathway reversed the promoting effect of SMOC2 overexpression on FMT. HBFs and IMR-90 cells were transfected with vector or SMOC2, and then treated with TGF-β1 or combined with PD98059 or LY294002. BrdU (A) and wound healing (B) assays were performed to assess cell proliferation and migration in HBFs and IMR-90 cells. **p < 0.01 compared with NT group; &&p < 0.01 compared with vector+TGF-β1 group; @@p < 0.01 compared with SMOC2 + TGF-β1 group. (C) The number of myofibroblasts in HBFs and IMR-90 cells was detected by flow cytometry analysis. **p < 0.01 compared with NT group; &&p < 0.01 compared with vector+TGF-β1 group; @@p < 0.01 compared with SMOC2 + TGF-β1 group. (D) The protein levels of collagen I and α-SMA in HBFs and IMR-90 cells were measured by western blot analysis. **p < 0.01 compared with NT group; &&p < 0.01 compared with vector+TGF-β1 group; @@p < 0.01 compared with SMOC2 + TGF-β1 group. (E) IF staining was performed to examine the protein content and distribution of α-SMA in HBFs and IMR-90 cellsBack to article page
