Figure 2. Effects of IL-12 on the mRNA levels of MMP-1, MMP-2, MMP-3, MMP-9, MMP-13, TIMP-1, and TIMP-2 in hPDLFs.

Figure 2

hPDLFs were treated with 0, 5, and 10 ng/ml of IL-12 for 12 and 24 h, and then the mRNA expression levels of MMP-1, MMP-2, MMP-3, MMP-9, MMP-13, TIMP-1, and TIMP-2 were determined by real-time PCR. Relative mRNA levels were presented as the ratios relative to untreated cells after normalization for their respective GAPDH mRNA expression. Data represented as means ± S.E.M. (n=3). *P<0.05 and **P<0.01, compared with the untreated group (0 ng/ml of IL-12).
