Correlation between pro-inflammatory cytokine IL-6 expression and MMP and ADAMTS: A post hoc analyses of the intercorrelation between IL-6 mRNA expression to the expression of different MMPs and ADAMTSs revealed significant positive correlations between (A) IL-6 and MMP1(r = 0.36, p = 0.04), (B) MMP10(r = 0.36, p = 0.037), (C) MMP13 (r = 0.34, p = 0.05), (D) ADAMTS1 (r = 0.35, p = 0.049), (E) ADAMTS4 (r = 0.42, p = 0.016), (F) ADAMTS5 (r = 0.39, p = 0.024). p<0.05 (two tailed) are considered statistically significantly for all comparisons.
