Examples of lncRNA genes having roles in lung tumorigenesis are H19, metastasis associated lung adenocarcinoma transcript 1 (MALAT1), smoke and cancer-associated lncRNA-1 (SCAL1), lncRNA-LET, intronic ncRNA AK126698, BC-200 and hox transcript antisense intergenic RNA (HOTAIR) [6-11]. Here, H19 is linked to cancer.
