[Research of RAAS: progress and perspective].

Pharmacological inhibitions of the renin-angiotensin-aldosterone system (RAAS) are crowned with one of the greatest success in the current field of cardiovascular medicine. In addition to the systemic effects including elevation of blood pressure and retention of sodium and water, sustained and excessive RAAS activation has direct and deleterious effects on a wide variety of tissues. Recent studies have deciphered the regulatory mechanisms underlying tissue RAAS activation at cellular and molecular levels, and suggested pathogenic roles of RAAS activation in hitherto unanticipated disorders such as muscular dystrophy, osteoporosis, cancer, and aging itself. Novel drugs targeting RAAS are under research and development in search for further efficacy, specificity, and even multifunctionality. This review will discuss the current progress and future perspective of RAAS research.
