BUB1B (Supplementary Figure 9A) and NDC80 (Supplementary Figure 9C) were validated at a transcription level in multiple cancer types based on the Oncomine database in that BUB1B (Median rank 132, p-value=1.54e-06) (Supplementary Figure 9B) and NDC80 (Median rank 192.5, p-value=4.04e-08) (Supplementary Figure 9D) were highly expressed in ovary cancer samples compared with normal ovary tissues. This evidence concerns the gene BUB1B and ovarian cancer.
