Interestingly, we found that the gene expression levels of KIFC1 were significantly higher in serous ovarian adenocarcinoma (n = 154) when compared to all other subtypes (Borderline serous adenocarcinoma, n = 18 and Peritoneal serous adenocarcinoma, n = 22) (Fig. 2A). This evidence concerns the gene KIFC1 and ovarian serous adenocarcinoma.
