Outline of Final Research Achievements

This study has investigated the mechanisms of radioresistance concerning uterine cervical cancer stem cells, and explored the innovative treatments for cancer. We have identified the 43 mRNAs and several miRNAs that significantly differed in expressions between cancer stem and non-cancer stem cells. These mRNA includes ADAMT55, FRMD3, COL8A1, and miR-377-3p、has-miR-654-3p in miRNA. Concerning miR-654-3p, significant difference in survivals were observed between patients with high expression and those with low expression usung TCGA database. We will continue the studies especially using the clinical samples in future.
