[The ACE2/Ang(1-7)/Mas receptor axis in cardiovascular and renal diseases].

The renin-angiotensin-aldosterone system(RAAS) plays a crucial role in the regulation of physiological homeostasis and diseases such as hypertension, coronary artery disease and chronic renal failure. In this cascade, the ACE/Ang II/AT1 receptor axis induces pathological effects, such as vasoconstriction, cell proliferation and fibrosis. Recently the ACE2/Ang(1-7)/Mas receptor axis has been recognized as a negative regulator of the RAAS. ACE2 metabolizes Ang II into Ang(1-7), which has opposite properties of Ang II through Mas receptor activation. Both animal and human studies provide strong evidence that the ACE2/Ang(1-7)/Mas receptor axis is protective for end-organ damage. Therefore, the ACE2/Ang(1-7)/Mas receptor axis could be a therapeutic target for coronary artery disease and chronic renal failure.
