DUXAP9 and non-small cell lung carcinoma: According to the intersection of up-regulated lncRNAs in GSE18842 and GSE19188, seven lncRNAs (LINC00511, LINC01133, DUXAP10, LINC01296, BBOX1-AS1, AFAP1-AS1 and LINC01116) were found to be highly expressed in NSCLC tumor tissues in both datasets (Fig. 1 c).
