Messenger ribonucleic acid expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 genes in the comparison of the β-actin gene between the placebo and curcumin groups A: Based on the charts, the mRNA expression of matrix metalloproteinase-9 (MMP-9) showed a significant decrease in the curcumin group compared to the placebo group after 3 months of curcumin administration (***P < 0.0010). B: Based on the charts, the mRNA expression of MMP-2 in the curcumin group did not show a significant decrease compared to the placebo group after 3 months of curcumin administration (P = 0.2800). Data are representative of at least 2 independent experiments with β-actin used as the internal control.
