Suppression of aggrecanase: a novel protective mechanism of dehydroepiandrosterone in osteoarthritis?
Aggrecanase-mediated aggrecan degradation is a significant event in the early stages of osteoarthritis (OA). There has been much interest in the possible role of these aggrecanases, mainly aggrecanase-1 (ADAMTS4) and aggrecanase-2 (ADAMTS5), as therapeutic targets in OA.
