qHTS Assay for Agonists of the Relaxin Receptor RXFP1: Summary

The relaxin hormone is involved in the variety of biological functions in normal tissues and diseases. The role of relaxin is well-established in female reproduction and parturition, mammary gland and endometrial development, maintenance of myometrial quiescence during pregnancy. Relaxin signaling through its G protein-coupled receptor (GPCR) RXFP1 results in ECM remodeling through regulation of more ..

NCGC Assay Overview:

The relaxin hormone is involved in the variety of biological functions in normal tissues and diseases. The role of relaxin is well-established in female reproduction and parturition, mammary gland and endometrial development, maintenance of myometrial quiescence during pregnancy. Relaxin signaling through its G protein-coupled receptor (GPCR) RXFP1 results in ECM remodeling through regulation of collagen deposition, cell invasiveness, proliferation and overall tissue homeostasis. Significantly, the therapeutic effects of relaxin in the treatment of renal, cardiac, skin, lung fibrosis, inflammation, and wound healing in animal models are well-established. Recombinant human relaxin (rhRlx) is currently being tested in clinical trials as a protective agent in congestive heart failure, in treating severe preeclampsia, and as an anti-fibrotic agent in systemic sclerosis.

Upon relaxin binding RXFP1 activation leads to the activation of adenylate cyclase (AC) via Gs. cAMP will activate PKA, which phosphorylates many signaling proteins. Thus, detection of cAMP increase is an easy and reliable indication of relaxin receptor activation. To screen for agonists of the relaxin receptor, a HEK293T cell line stably transfected with RXFP1 was used. RXFP1 activation was assayed by changes in cAMP levels as detected with a time-resolved fluorescence energy transfer (TR-FRET) cAMP detection kit.
