Impact of mediator nitric oxide on gene expression in human chondrocytes

ABSTRACT: Osteoarthritis (OA) is an aging-associated disease of diarthrodial joints that involves changes in the bone, cartilage and soft tissue. Chondrocytes are the only cell type in cartilage and play a pivotal role in tissue homeostasis and cartilage remodeling in OA. Age- or OA-dependent metabolic changes affecting extracelluar matrix composition as well as variations in the response to cytokines and growth factors have been investigated in human chondrocytes. However, the molecular mechanisms causing age-dependent variation of the chondrocyte phenotype are poorly characterized. The proinflammatory mediator nitric oxide (NO) is produced when chondrocytes are exposed to cytokines such as IL-1. NO affects the energy metabolism of cells through interfering with mitochondrial respiration and glycol
