CEACAM6, a cell surface glycoprotein, is significantly overexpressed in CRC tissues and correlates with tumor growth; HOXA-AS3, a long non-coding RNA, regulates cellular proliferation via epigenetic mechanisms; and miR29a, a miRNA, modulates key oncogenic pathways through post-transcriptional gene silencing. This evidence concerns the gene CEACAM6 and colorectal carcinoma.
