Fig. 1: Identification of dysregulated lncRNAs in LUAD.

a Cluster analysis of differentially expressed lncRNAs from microarray dataset GSE27262. b Relative expression levels of lncRNA candidates quantified by qRT-PCR in clinical samples. c Relative linc00665 expression in LUAD from TCGA database. In all, 533 LUAD tumor tissues and 59 normal tissues, respectively. d Linc00665 expression data from TCGA was analyzed by Cancer RNA-seq Nexus.
