Upregulation of CDK1 was observed in various cancers like human colorectal cancer [46], gastric lymphoma [47], Hodgkin’s lymphoma [48], prostate cancer [49], childhood acute lymphoblastic leukemia [50], and ovarian cancer [51]; hence, CKD1 is associated with the prognosis of multiple malignant tumors. This evidence concerns the gene CDK1 and colorectal cancer.
