P. gingivalis LPS1690- and E. coli LPS-induced gene expression of MnSOD, TXN1 and PRDX1 mRNAs in HGFs.
Cells were stimulated with P. gingivalis LPS and E. coli LPS at 1 μg/mL for 24 h. After LPS stimulation, harvested RNA was subjected to real-time qPCR analysis. Fold changes of SOD1 and MnSOD (A) TXN1 and TXN2 (B), PRDX1 and PRDX2 (C) gene expression were shown with reference to internal control β-actin. Each bar represents the mean ± SD of three independent experiments with three replicates. *Significant difference with a P-value < 0.05 as compared with the controls without LPS treatment.
