In the present study, we have revealed that FBW7 is downregulated in ovarian carcinomas compared to non-cancerous ovarian tissues (Fig. 1a-b, Supplementary Fig. 1A-B) and that lower expression level of FBW7 is associated with unfavorable prognosis (Fig. 1e-f, Supplementary Fig. 1C), which is consistent with the previous study [21]. This evidence concerns the gene FBXW7 and ovarian carcinoma.
