P. gingivalis LPS decreased apoptosis of WPMY-1 cells and increased cell growth. a Flow cytometry apoptotic representative images and apoptosis rate histogram of WPMY-1 cells treated with selected concentrations of 0, 0.1 and 1 μg/ml P.g-LPS for 24 h. b Flow cytometry representative images and quantitative analyses of cell cycle of WPMY-1 cells treated with selected concentrations of 0, 0.1 and 1 μg/ml P.g-LPS for 24 h. c Cell viability of WPMY-1 cells treated with 0, 0.1 and 1 μg/ml P.g-LPS at different time points of 0, 24, 48 and 72 h by CCK-8 assay. Data are expressed as mean ± SD. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001. LPS lipopolysaccharide, PE phycoerythrin, APC Allophycocyanin, FITC fluoresceinisothiocyanate
