Abstract EN
Osteoarthritis (OA) is a joint disease characterized by cartilage degeneration.
Osteopontin (OPN) is involved in the initiation, repair, and maintenance of metabolic homeostasis in normal articular cartilage.
This study investigated the role of OPN and its interaction with the integrin ανβ3 receptor in the expression of hyaluronic acid (HA) in OA chondrocytes.
Overexpression of OPN significantly increased the expression of integrin ανβ3 and hyaluronic acid synthases (HAS) and synthesis of HA.
Depleting OPN in OA chondrocytes showed the opposite trend for integrin alpha;νβ3, HAS, and HA.
Nonspecifically and specifically blocking integrin receptor using GRGDSP and integrin ανβ3 antibody downregulated HAS and HA; both were inhibited to similar extents.
The expression of HAS and HA was predominantly regulated by the interaction between OPN and integrin ανβ3.
Taken together, we have delineated the importance of the OPN/integrin ανβ3/HAS/HA axis in OA and identified OPN as a promising candidate for molecular therapy for use in patients with OA.
