Abstract
The degradation of type IX collagen, a minor collagen in cartilage, was examined by treatment with three different types of matrix metalloproteinases (MMPs) purified from the culture medium of rheumatoid synovial cells. Neither MMP-1 (collagenase) nor MMP-2 (so-called 'gelatinase') could digest type IX collagen, but MMP-3 (stromelysin) readily degraded it into smaller fragments. This suggests that MMP-3 may be responsible for the pathological degradation and/or normal turnover of type IX collagen.
