Effect of emodin on the mRNA and protein expression of MMP3 and MMP13 in chondrocytes induced by H2O2. (a) The protein expression levels of MMP3 and MMP13 were evaluated by Western blots and (b) quantified. (c) The mRNA expression levels of MMP3 and (d) MMP13 were evaluated by qPCR. (e) Heatmap of MMP3 and MMP13 expression in chondrocytes induced by H2O2. The data were expressed as the (). .
