About Relaxin
Binds RXFP1 receptor, activating adenylyl cyclase and cAMP/PKA pathway. Upregulates matrix metalloproteinases (MMPs) to degrade excess collagen. Inhibits TGF-β fibrotic signaling. Promotes cervical softening and pelvic ligament compliance.
A peptide hormone produced by the corpus luteum during pregnancy and in small amounts in non-pregnant individuals. Remodels connective tissue, relaxes pelvic ligaments, and has potent anti-fibrotic effects. Studied for pelvic floor dysfunction, fertility support, and cardiac fibrosis.
