In right colon cancer, the most significant signal was located in NTF3, a gene implicated in unfavorable prognosis in hepatocellular carcinoma [58,59]; in left colon cancer ABCC12 gene, another ATP-binding cassette as the previously discussed ABCA12; in rectal cancer BRD7 gene, a possible oncogene involved in CRC progression [60]. This evidence concerns the gene BRD7 and rectal cancer.
