The modulation of matrix metalloproteinase and ADAM gene expression in human chondrocytes by interleukin‐1 and oncostatin M: A time‐course study using real‐time quantitative reverse transcription–polymerase chain reaction

Abstract

These data indicate that the potent cartilage-degrading properties of the combination of IL-1 and OSM are potentially mediated by a synergistic induction of the aggrecan-degrading enzyme ADAM-TS4 and the collagen-degrading enzymes MMP-1, MMP-8, MMP-13, and MMP-14, although differences in the magnitude of response and in the time course of induction were observed. A role for MMPs 3 and 14 in the activation of proMMPs may also be implicated.
