Bioinformatic analyses in TCGA (The Cancer Genome Atlas) database and gene expression analyses in CRC tumor tissues and cultured tumor cells demonstrate that a variety of tumor suppressors [e.g., p53, APC (Adenomatous Polyposis Coli), LOH (Loss of Heterozygosity), PTEN (Phosphatase and Tensin Homolog) and ST7 (Suppressor of Tumorigenicity protein 7] and oncogenes [e.g., KRAS (Kirsten Rat Sarcoma), c-Myc, Her2 (Human Epidermal Growth factor receptor 2)] are differentially expressed 14, 15. Here, ERBB2 is linked to colorectal carcinoma.
