SNHG12 is involved in different types of malignant diseases by targeting the following microRNAs: miR-424-5p in cervical cancer (124), miR-320 in gastric cancer (125), miR-199a-5p in renal cell carcinoma (126), miR-199a/b in hepatocellular carcinoma (32), miR-199a/b in gastric cancer (127), miR-138 in lung cancer (32), miR-181a in lung cancer (128), miR-16-5p in thyroid carcinoma (129), miR-129-5p in laryngeal squamous cell carcinoma (130), miR-199-5p in renal carcinoma (126), and miR-195-5p in osteosarcoma (131). The gene discussed is SNHG12; the disease is hepatocellular carcinoma.
