Otherwise, the protein expression levels of TRADD, H2AC6, VDAC3, JMJD7-PLA2G4B, TRAF2, and DAPK1 in colon cancer tissues and normal tissues in the HPA database were shown, which were consistent with the expression levels of these genes in RNA levels. This evidence concerns the gene DAPK1 and malignant colon neoplasm.
