title: MicroRNA in osteoarthritis.
abstract: Osteoarthritis (OA) is the most prevalent degenerative joint disease and is accompanied by pain and joint dysfunction. Its clinical treatment tends to be unsatisfactory. Novel targets in OA include genes that are involved in OA pathophysiology and have been discovered using gene network, epigenetic and microRNA (miRNA) approaches. miRNA has been implicated in important cellular processes such as lipid metabolism, apoptosis, differentiation and organ development. The importance of miRNA regulation in cellular function is becoming increasingly clear as new miRNA targets are revealed. The present review summarizes the current evidence of the important role played by miRNA in determining the complex gene expression patterns of OA chondrocytes and their role in the regulation of transcription, and possible demethylation mechanisms that might be applicable in OA. In summary, miRNA may have important diagnostic and therapeutic potential, and might provide a novel means of treating OA.
