Double‐knockout of ADAMTS‐4 and ADAMTS‐5 in mice results in physiologically normal animals and prevents the progression of osteoarthritis

Abstract

Dual deletion of ADAMTS-4 and ADAMTS-5 generated mice that were phenotypically indistinguishable from WT mice. Deletion of ADAMTS-4/5 provided significant protection against proteoglycan degradation ex vivo and decreased the severity of murine OA. These effects in the ADAMTS-4/5-double-knockout mice were comparable with those observed with deletion of ADAMTS-5 alone.
