LINC00968 and lung carcinoma: We observed that LINC00968 was significantly downregulated in lung tumours compared with paired normal lung and completely absent in lung cancer cell lines, which is in contrast to a previous study reporting upregulation of LINC00968 in NSCLC.50 However, that study evaluated LINC00968 expression using datasets from the Oncomine database and four NSCLC cell lines, whereas we performed wet validation in 82 NSCLC tissue samples and 13 NSCLC cell lines.
