英文摘要
The aim of this study is to investigate the role of microRNAs (miRNAs) during gastric carcinogenesis and the feasibility of epigenetic therapy for gastric neoplasms.MiRNA microarray analyses revealed that miR-29c was significantly down-regulated in gastric cancers and that miR-142 and miR-155 were overexpressed in gastric MALT lymphomas. MiR-1246, miR-302a and miR-4448 were up-regulated by treatment of gastric cancer cells with EZH2 inhibitors such as SAHA and DZNep. In addition, we have developed a novel miRNA promoter microarray for chromatin immunoprecipitation (ChIP)-on-chip assay. Using this custom-made miRNA promoter microarray, we have successfully performed ChIP-on-chip assay to identify miRNAs regulated by histone modification. These results indicate that misexpression of miRNAs plays critical roles during gastric carcinogenesis and that epigenetic therapy with chromatin-modifying drugs exert multiple anti-cancer effects through activation of tumor-suppressor miRNAs.
