ObjectiveRecent advancements in the researches on cholangiocarcinoma (CC) related genes methylation in CC were reviewed and the clinical significances of aberrant DNA methylation for the diagnosis and treatment of CC were discussed. MethodsRelevant literatures about the relation between CC-related genes methylation and CC published recently were collected and reviewed. ResultsThe genesis of CC resulted from abnormal expressions of many genes. Many researches had shown that the abnormal methylation of CC-related genes had a close relation with CC. Epigenetic alteration had been acknowledged as an important mechanism contributing to early CC carcinogenesis. ConclusionsAbnormal methylation of CC-related genes is related with CC. The detection of CC-related genes methylation might provide new specific biomarkers for early noninvasive diagnosis of this disease. Using epigenetic agents such as azacytidine to modulate the activities of DNA methyltransferase and reverse the methylation status of CC-related gene might be an attractive strategy for future treatment of CC, which could be combined with conventional therapies.
