| Research Abstract |
We assumed that we can obtain favorable therapy results by establishing a new selective cancer therapy through analyzing an expressed molecular to ovarian cancer stem cells, selecting more specific molecular to ovarian cancer stem cells, and use them as a marker for the therapy. Firstly, In cell cycle GO phase, we detected three genes ; ABCG2 which relate to anticancer drug efflux, FOXO3a that is a GO phase suppressor gene and specific expression of ubiquitin ligases subunites F bw7. We also detected high expression of microRNA for regulating ABCG2 gene in GO cells. Whereas, By side population (SP) method, we detected the cancer stem cell in clear cell ademocarcinoma which include high frequency SP cells. Since these cells showed adipocytes-like character similar to a clinical picture and PPARγ that specific gene to adipocytes was highly expressed, an anticancer drug does not effect well and maintain of cell undifferentiation. We detected similar genes at malcroarray.
