Expression of THBS4 in PAH rats induced by MCT plus aorto-caval shunt. (A) THBS4 expression in GSE149899. qRT-PCR (B) and Western blot (C) showed the time course of THBS4 expression in PAH rats induced by MCT plus aorto-caval shunt. (D) Double immunofluorescence staining of THBS4 with α-SMA or VWF. Scare bars: 50 μm. CON: the control group; SHAM: the sham group; MS: PAH rats induced by MCT plus aorto-caval shunt (MS) from 1 week (1w) to 4 weeks (4w). The resultant data are represented as mean ± SD. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
