Comparison between gene expression in periodontitis and laboratory culture for Porphyromonas gingivalis. (A) Principal coordinates analysis (PCoA) of transcriptional profiles from four periodontal pocket samples (chronic periodontitis) and laboratory cultures on three different media. (B,C) Gene ontology (GO) terms up-regulated (B) and down-regulated (C) in periodontitis. All GO terms with enrichment P-value ≤ 0.05 were summarized and visualized by REVIGO (Supek et al., 2011), and the size of the bubble indicates the number of merged terms.
