Because different types of OC have different characteristics, and the OC samples in the TCGA database are all ovarian serous cystadenocarcinoma (OV), so we analyzed the expression of IGF2BP1, VIRMA and ZC3H13 in different types of OC in the Oncomine database (https://www.oncomine.org) (Supplementary Figure 6A–6C). This evidence concerns the gene VIRMA and ovarian serous cystadenocarcinoma.
