LncRNAs, such as LINC01123, DUXAP8, BCYRN1, LINC00243, HOXA11-AS, MALAT1, SNHG14, and FAM83A-AS1, are significantly upregulated in lung cancer tissues and are closely associated with tumor stage, lymph node metastasis risk, and poor prognosis (66, 69, 75, 77, 78, 85, 102, 103). The gene discussed is MALAT1; the disease is lung carcinoma.
