Increased expression of CDC20 in colorectal cancer. A, Western blotting analysis of CDC20 expression in normal colon epithelial cell lines and colon cancer cells. The quantitative data are shown. Bars: SD; *: P < 0.05. B, Immunostaining of CDC20 in six pairs of representative colorectal tumor tissues (T) with adjacent non-cancerous tissues (N) (left panel). The quantitative analysis is also shown (right panel, Wilcoxon signed rank test, n = 126, P < 0.001). C, Immunostaining of CDC20 in three pairs of representative primary tumor tissues (P) with liver metastasis tumor tissues (M) (left panel). The quantitative analysis is also shown (right panel, Wilcoxon signed rank test, n = 20, P < 0.001).
