Validation of biological effect according to gene expression profiling analysis. a The fold changes of PG1151 and PG1152 gene expression levels in Porphyromonas gingivalis after Nal-P-113 treatment. b Free hemin concentration in P. gingivalis W83 culture medium either with or without treatment of Nal-P-113. c Hemoglobin concentration in P. gingivalis W83 culture medium either with or without treatment of Nal-P-113. d The expression of transposases levels in Porphyromonas gingivalis after 3 mM H2O2 treatment for one hour. e Biofilm susceptibility assay of Nal-P-113-treated P. gingivalis W83 with or without H2O2 pretreatment. Data shown here are the mean ± S.D. from three independent cultures, *, P < 0.05, **, P < 0.01
