As shown by the IHC staining results for 301 endometrial carcinoma and 38 non-cancer endometrium tissues, CKS2 expression was remarkably higher in the glandular epithelial cells of endometrial carcinoma tissues than in non-caner endometrium tissue (9.071 ± 1.122; 5.789 ± 1.788, p < 0.001) (Figure 5). This evidence concerns the gene CKS2 and endometrial carcinoma.
