Figure 1A showed that the expression of ORC1 in most tumor tissue was higher than that of the normal tissue, such as Bladder Urothelial Carcinoma (BLCA) (T = 408, N = 19), Breast invasive carcinoma (BRCA) (T = 1093, N = 112), Colon adenocarcinoma (COAD) (T = 457, N = 41) and so on. This evidence concerns the gene ORC1 and colon adenocarcinoma.
