Recently chronic inflammation is focused on the association with cancer progression and acquisition of aggressive biologic behaviors, such as invasion, metastasis, and resistance to chemotherapeutic reagents. Due to the close vicinity within oral cavity, oral cancer may be intimately associated with chronic periodontitis. The present study was done to observe the effect of chronic periodontitis on oral cancer cells by utilizing P. gingivalis infection, a major pathogen in chronic periodontitis. We analyzed and compared the mRNA expression levels of epithelial-mesenchymal transition (EMT) markers in non-infected and P. gingivalis-infected oral cancer cells. Eighty-six genes, which are well known as EMT markers, were analyzed using commercially available EMT microarray plates, performed in triplicate. Among the 86 genes, the expression of 26 was increased (≥ 2 fold) by P. gingivalis, whereas that of 7 genes was decreased (≥ 2 fold). Our study suggests that P. gingivalis infection evokes significant changes in EMT-related genes. Further observations on molecular mechanisms underlying these changes may help to clarify the role of chronic periodontitis on cancer progression and to develop more efficient preventive and therapeutic modalities for oral cancer.
