Fig. 5. PDCD5 promotes fibroblast activation via secretion of matricellular proteins.

Fig. 5

a C22 cells were plated on transwells and transfected with Pdcd5 siRNAs. Mouse primary lung fibroblast cells (MLFs) were plated in 24-well plates a day before TGF-β1 treatment. Transwells were transferred to Mlg-containing 24-well plates. After 24 h TGF-β1 treatment, MLFs were counted using an automated cell counter (n = 3 in each group); ****p < 0.0001. b MLFs were cultured in C22 conditioned medium (CM). The levels of indicated genes were analyzed by qRT-PCR (n = 3 in each group) *p = 0.0265; ***p = 0.0002; ****p < 0.0001; n.s. not significant. Error bars represent mean ± s.e.m., statistical analysis was performed with one-way ANOVA followed by Tukey’s test (a, b). c C22, RLE-6TN, and Mlg cells were treated with TGF-β1 for 24 h. Enriched media and cell lysates were used for immunoblotting with indicated antibodies. Representative blots from three independent experiments are shown. d IHC with indicated antibodies was performed in the lung tissue from Pdcd5f/f and Ccsp-Pdcd5d/d mice. Scale bars = 100 μm. Representative images from three mice in each group are shown. Source data are provided in the Source Data file.
