[Diabetes mellitus].

Recently renin-angiotensin-aldosterone system (RAAS) including angiotensin converting enzyme (ACE) 2-angiotensin (Ang)-(1-7) system may concern both pancreatic insulin secretion and insulin resistance (IR). Actually, Ang II introduces pancreatic beta-cell apoptosis and suppresses insulin signal transduction by modulation of adipokines. Ang II also suppresses GLUT4 expression and AMP kinase activity. All of them introduce new onset diabetes mellitus and various kinds of diabetic complications. RAAS suppression by using not only ACE inhibitor, Ang II receptor blockade (ARB) but also aldosterone receptor blockade improved insulin secretion and IR. Clinically, ACE inhibitor and ARB suppress new onset diabetes mellitus and diabetic complications. In this review we will focus on the recent findings related RAAS and glucose metabolism and diabetic complications with special reference to ACE2-Ang-(1-7) system.
