BI113823 reduces fibrosis in lung and heart in pulmonary arterial hypertension. A, B Masson trichrome staining for collagen (MTS) (blue color) in lung and heart, and their quantification. C Lung fibrosis, and D right ventricular fibrosis in each treatment group. Fibrotic gene expression of E CTGF, F Collagen I and G Collagen IV in lungs. All values are mean ± SEM, n = 6–8. #p < 0.05 vs. sham control, †p < 0.05 vs. control (D21); *p < 0.05 vs. vehicle
