Small nucleolar RNA host gene 3 (SNHG3) is a new type of lncRNA related to liver cancer, colorectal cancer, laryngeal cancer, and other cancers, and it is considerably upregulated in hepatocellular carcinoma and promotes cell invasion and epithelial-mesenchymal transition through the miR-128/CD151 pathway [20]. This evidence concerns the gene SNHG3 and liver cancer.
