Fig. 9From: 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 pathwayThe signaling pathways of this experiment. Baicalin exerted protective effects against hypoxic PASMCs via the upregulation of A2aR expression and downregulation of SDF-1/CXCR4 axisBack to article page
