In addition, 9 pathways were specifically active in the hypertension group, including signaling pathways that regulate vascular development in the embryo and were reactivated following vascular injury (EGF, BMP, RANKL, WNT, and ANGPT)41–44 and pathways that have not been fully studied in the cardiovascular system, such as PERIOSTIN, NPR1, and CHEMERIN. The gene discussed is POSTN; the disease is hypertensive disorder.
