Abstract
Relaxin is a pleiotropic hormone which exerts its biological functions through its G-protein coupled receptor, RXFP1. While relaxin is well known for its reproductive and antifibrotic roles, recent studies suggest that it is produced by cancer cells and acts on RXFP1 to induce growth and metastasis. Furthermore, more recently Silvertown et al. demonstrated that lentiviral production of a human gene-2 (H2) relaxin analog reduced the growth of prostate xenograft tumors. The authors proposed that the lentivirally produced peptide was an RXFP1 antagonist; however, the processed form of the peptide produced was not demonstrated. In this study, we have chemically synthesized the H2 relaxin analog,..
