Integrated microarray meta-analysis identifies miRNA-27a as an oncogene in ovarian cancer by inhibiting FOXO1

In summary, our results indicate that miR-27a can promote progression of ovarian cancer by mediating FOXO1. To our knowledge, this is the first study focusing on the role of miR-27a/FOXO1 axis using the microarray meta-analysis in ovarian cancer. Furthermore, inhibiting miR-27a expression may be a new strategy for the treatment of ovarian cancer.
