Abstract
Fibrosis (organ scarring) is a hallmark of many forms of cardiovascular and renal disease, and causes organ dysfunction and structural changes when normal tissue is replaced with scar tissue; the accumulation of scar tissue being a leading cause of death around the world. Despite deep organ scarring potentially existing in many forms (including myocardial and vascular sclerosis, renal interstitial fibrosis, and glomerulosclerosis), current therapies have only had limited success in delaying end-stage disease. The peptide hormone relaxin is emerging as a potent antifibrotic therapy with rapid-occurring efficacy. Recent studies have demonstrated the antifibrotic actions of relaxin in experimental models of cardiac and renal disease in vivo, and the various levels at which relaxin acts to inhibit fibroblast-induced collagen overproduction leading to fibrosis, in vitro. Separate studies using relaxin gene-knockout mice have demonstrated the significance of endogenous relaxin as a naturally occurring and protective moderator of collagen turnover, while the therapeutic potential of relaxin has been enhanced by its ability to promote vasodilation and renal hyperfiltration. This review will summarize these coherent findings as a means of highlighting the clinical potential of relaxin in cardiovascular and renal disease.
