Time-dependent expression of MMPs 1−3 and TIMP-1 mRNAs in P. gingivalis LPS-treated HGFs. Expression of MMP-1 (a), MMP-2 (b) MMP-3 (c) and TIMP-1(d) mRNAs after the stimulation of P. gingivalis (Pg) LPS1435/1449 (1 μg/ml), LPS1690 (1 μg/ml) and E. coli LPS (1 μg/ml) in a time-dependent assay (2–48 h). The expression of mRNAs was measured by real-time qPCR. Each bar represents the mean ± SD of three independent experiments with three replicates. *Significant difference (p < 0.05) as compared with the controls without LPS treatment.
