摘要
血管紧张素-(1-7)[Ang-(1-7)]是近年来发现的肾素-血管紧张素系统中一种内源性七肽,与血管紧张素转换酶2(ACE2)及 Mas 受体共同构成 ACE2-Ang-(1-7)-Mas 轴,起到拮抗 ACE-AngⅡ-AngⅡ1型受体轴的作用。近期发现除了其在心血管疾病中发挥作用外,在肿瘤的治疗中也有一定的作用,包括抑制血管生成、抗细胞增殖以及抑制肿瘤纤维化等。研究 Ang-(1-7)的作用及作用机制能够为肿瘤的治疗及预防提供新的研究方向。
Angiotensin-(1-7)[Ang-(1-7)]is an endogenous peptide-hormone of the renin-angioten-sin system. Ang-(1-7),angiotensin-converting enzyme 2( ACE2)and MAS receptor constitute ACE2-Ang-(1-7)-Mas axis,which antagonizes the ACE-AngⅡ-AngⅡ type 1 receptor axis. Recent studies indicate that Ang-(1-7)has certain effects on treating tumors,including inhibition of angiogenesis,anti-cell proliferation and inhibition of tumor fibrosis. Researches on the roles and mechanisms of Ang-(1-7)can provide new target for treatment and prevention of cancer.
