Fig. 6From: Enrichment of Prevotella intermedia in human colorectal cancer and its additive effects with Fusobacterium nucleatum on the malignant transformation of colorectal adenomasConditioned medium from Prevotella intermedia enhances CRC cell migration and invasion. CRC cells were incubated in the conditioned medium from Prevotella intermedia in the top chamber for migration (A–C) and invasion (D–F) assays. G–I Effect of proteinase K-treated conditioned medium from Prevotella intermedia on cell migration. The relative percentages of the migrated and invaded cells are presented as mean ± standard deviation. Data were obtained from three independent experiments. ****P value < 0.0001Back to article page
