Relaxin is a polypeptide hormone produced in the human female by the corpus luteum of pregnancy and the decidua. It’s most well-documented effects are on the menstrual cycle and during pregnancy. It is a key hormone which plays a major role during pregnancy, relaxing muscles, tendons, ligaments, and joints so that the body can handle the effects of a growing fetus. Although relaxin plays a major role during pregnancy, there are many other uses of relaxin. Relaxin enhances nitric oxide, prostacyclin and endothelium-derived hyperpolarization (EDH)-type-mediated relaxation in various vascular beds. These effects of relaxin on the systemic vasculature, coupled with its cardiac actions, reduce pulmonary capillary wedge pressure and pulmonary artery pressure. This results in an overall decrease in systemic and pulmonary vascular resistance in heart failure patients. The anti-fibrotic actions of relaxin are well established, a desirable property in the context of diabetes. Further, relaxin ameliorates diabetic wound healing, with accelerated angiogenesis and vasculogenesis. Relaxin-mediated stimulation of vascular endothelial growth factor (VEGF) and stromal cell-derived factor 1-α, as well as regulation of metalloproteinase expression, ameliorates cardiovascular fibrosis. Recent studies suggested that relaxin plays a beneficial role in treating cardiac problems, musculoskeletal problems and acts as anti- fibrotic agent, anti-inflammatory agent.
