| Outline of Final Research Achievements |
This study assessed the impact of microRNA which regulates function of c-myc. Oncogenic c-mMyc dimerizes with max to bind DNA and regulates gene expression, which relies on the regulatory network of the c-myc binding protein (MYCBP). We found that ectopically expressed miR-22 inhibited MYCBP expression, resulting repression of human telomerase reverse transcriptase (hTERT) production. Moreover, the introduction of miR-22 enhanced radiosensitivity in cervical cancer cells. Taken togethether, our data suggest that miR-22 inhibits MYCBP expression, leading to the decreased expression of hTERT which is one of the target genes of c-myc, resulting in increased radiosensitivity in cercical cancer.
