Fig. 4From: Baicalin promotes apoptosis and inhibits proliferation and migration of hypoxia-induced pulmonary artery smooth muscle cells by up-regulating A2a receptor via the SDF-1/CXCR4 signaling pathwayBaicalin intervention enhanced A2aR expression. a: Images and quantitave analysis of A2aR expression in PASMCs by western blot assay. Tubulin served as an internal control. b: Rt-qPCR indicated that baicalin upregulated A2aR mRNA in hypoxic PASMCs. c: SDF-1 expression increased in KD/H + Bai group compared with H + Bai group. d: CXCR4 expression increased in KD/H + Bai group compared with H + Bai group. # P < 0.05, ##p < 0.01 vs normoxia group, * P < 0.05 **P < 0.01 vs hypoxia group; + p < 0.05, ++ p < 0.01 Comparison between groups. n = 3Back to article page
