Additional Information

Osteoarthritis (OA) is a common degenerative joint disease for which an effective therapeutic strategy has not yet been established. AGEs are widely recognized as a contributor to OA pathogenesis. GPR4, a recently discovered proton-sensing transmembrane receptor, has been shown to possess a wide range of physiological functions. However, the potential role of this receptor in chondrocytes and the pathogenesis of OA is unclear.
