Among these common DEGs, a selection of these genes involved in cancer biology is shown in Table 1, including abca13, ceacam6, and reg4 involved in acquisition of the chemotherapy-resistant phenotype; cemip, cxcr4, fzd7, mrc2, pitpnm3, and clic2 playing a role in chemotactic cell migration, invasion, and metastasis; and pcdh1 and s100p increasing PCa cell growth. Here, CEACAM6 is linked to cancer.
