Figure Lengend Snippet: (A) Graphical presentation of experimental design; wild-type mice were challenged to one dose of intratracheal administration of bleomycin (2.5 mg/kg body weight) at day 0 followed by intraperitoneal injection of verteporfin (50 mg/kg body weight) or DMSO from day 1 until day 19, at every alternative day as indicated. DMSO was used as vehicle control. Lungs were harvested at 21 days post-bleomycin injury to assess the lung fibrosis. (B-C) Sirius Red/Fast Green staining and quantification (presented as Ashcroft score) on lung sections from wild-type mice (n = 5-6) treated with DMSO or bleomycin with/without verteporfin for 21 days. (D) Quantification of hydroxyproline content using lung tissue from wild-type mice (n = 5-6) treated with DMSO or bleomycin with/without verteporfin for 21 days. (E) Real-time qPCR for profibrotic genes Acta2 , SM22α , Col1a1, P4ha1, Plod2, Periostin and Ccl2 on lung tissue from wild-type mice (n = 5) treated with DMSO or bleomycin with/without verteporfin for 21 days. (F-G) Immunoblot analysis and quantification of Yap, Taz, collagen I and αSMA protein levels using lung tissue lysate from wild-type mice (n = 5) treated with DMSO or bleomycin with/without verteporfin for 21 days. Quantification of indicated proteins relative to β-actin. (H-I) Immunofluorescence staining and quantification of αSMA and collagen I in lung sections from wild-type mice (n = 5) treated with DMSO or bleomycin with/without verteporfin for 21 days. (J-K) Immunostaining and quantification of Pro-SPC+AT2-cells and Hopx+AT1-cells in wild-type mouse lungs (n=5) treated with DMSO or bleomycin with/without verteporfin for 21 days. Fluorescence intensity was quantified with imageJ software. The data are represented as the mean ± SEM; comparison by one-way ANOVA, followed by Tukey’s post-hoc test. *, p < 0.05; **, p < 0.01; ***, p < 0.001; NS, not significant.
Article Snippet: Adult human control lung tissues were purchased from Novus Biologicals (Catalogue no. NBP2-77573, NBP2-30182 and NBP2-42696) and human lung tissues diagnosed with fibrotic diseases were purchased from Origene (Catalogue no. CS504154, CS600794 and CS505314).
