Interleukin-1 induction of collagenase 3 (matrix metalloproteinase 13) gene expression in chondrocytes requires p38, c-jun N-terminal kinase, and nuclear factor κB: Differential regulation of collagenase 1 and collagenase 3

Abstract

These studies demonstrate, for the first time, that p38, JNK, and NF-kappaB are required for IL-1 induction of MMP-13. The results also highlight the differential requirements for signaling pathways in the induction of MMP-1 and MMP-13. Additionally, they demonstrate that induction of MMP-1 by IL-1 in chondrocytic cells depends on unique combinations of signaling pathways that are cell type-specific.
