Osteoarthritis (OA) is characterized by irreversible destruction of the articular cartilage. OA affects more than 100 million individuals worldwide and has a major impact on patients quality of life. The lack of effective therapy that prevents, inhibits or reverses the progress of OA often leaves only the option of surgical interventions. Thus, identification of the factors that contribute to OA pathogenesis is necessary for better understanding of OA pathobiology and discovery of effective therapies. Recent proteomic studies have been conducted to identify pathological mediators and biomarkers of OA, which have pinpointed novel pathways involved in cartilage degeneration. This article summarizes the recent findings, compares major techniques used in OA proteomics and discusses key proteins in OA and their potential use as therapeutic targets.
