To investigate the biological function of FBXO22 in epithelial ovarian cancers cell proliferation, we transfected HO8910 and OVCAR3 cells with negative control siRNA (NC) and siRNAs targeting FBXO22 (si#1, si#2 and si#3) successively (Figure 2A). This evidence concerns the gene FBXO22 and ovarian carcinoma.
