Fig. 5From: Activation of calcitonin gene-related peptide signaling through the prostaglandin E2-EP1/EP2/EP4 receptor pathway in synovium of knee osteoarthritis patientsEffects of PGE2 and EP agonists on RAMP1 protein expression in synovial cell culture. Western blotting analysis for RAMP1. Synovial cells were stimulated with 10 μM PGE2, iloprost (EP1), butaprost (EP2), sulprostone (EP3), or CAY10598 (EP4) for 24 h prior to protein extraction and analysis of RAMP1 proteinBack to article page
