Inflammatory processes, particularly those arising from trauma or injury to the region of a bone joint, are causative of osteoarthritis (OA). A composition comprising microRNA-122, microRNA-122 mimic, and/or an inhibitor of microRNA-451 reduces or inhibits inflammatory mediators in articular chondrocytes and related cells. When administered to a subject at risk of developing OA, development of OA and/or progression of OA disease are inhibited, and cartilaginous structures are preserved in the joint. Since joint injury is associated with subsequent development of OA, the treatment is particularly suitable following an acute injury to a joint. |
