The transforming growth factor-β/bone morphogenic protein (BMP) system is a major pathway for angiogenesis and is involved in hereditary vascular diseases. Here we report that the gene encoding the vasoactive and vascular cell growth-regulating peptide apelin is a target of the BMP pathway. We demonstrate that apelin expression is strongly downregulated by BMP in an endothelial cell line as well as in lung endothelial microvascular cells. We show that BMP signals through the BMPR2-SMAD pathway to downregulate apelin expression and that a transcriptional direct and indirect mechanism is required. The BMP-induced downregulation of apelin expression was found to be critical for hypoxia-induced growth of endothelial cells, because the growth inhibitory effect of BMP in this condition is suppressed by enforced expression of apelin. Thus, we describe an important link between a signaling pathway involved in angiogenesis and vascular diseases and a peptide regulating vascular homeostasis.
