Identification of potential biomarkers for idiopathic pulmonary fibrosis and validation of TDO2 as a potential therapeutic target

Figure 8 Western blot analysis of α-smooth muscle actin and COL-1 in A549, MLE-12, and IMR-90 cells. Western blot quantification results in A549, MLE-12 and IMR-90 cells. A and D: A549; B and E: MLE-12; C and F: IMR-90. In line with the homogeneity of variance, the least significance difference method was used when assuming homogeneity of variance. ^aP < 0.01 vs phosphate-buffered saline; ^bP < 0.05 vs transforming growth factor-β. PBS: Phosphate-buffered saline; α-SMA: α-smooth muscle actin; TGF-β: Transforming growth factor-β.
