Activin receptor-like kinase 1 and its roles in angiogenesis / 中国病理生理杂志

ABSTRACT

Activin receptor-like kinase (ALK) 1 is a transforming growth factor-β/bone morphogenetic pro-teins superfamily type Ⅰ receptor, predominantly expressed in active endothelial cells. ALK1 has been shown to play a piv-otal role in regulating angiogenesis, which is involved in vascular formation during embryonic and early postnatal develop-ment and angiogenesis-related diseases, such as cardiovascular disorders and tumor. Understanding the exact function of ALK1 in angiogenesis will provide theoretical basis for anti-angiogenic strategy of ALK1 inhibition. In the present study, we briefly recapitulate ALK1 signaling pathway and its role in blood vessel formation and pathological neovascularization.
