Screening differentially expressed lncRNAs (DELs) in three groups. a–c The volcano plots of DELs in the TCGA_NSCLC group, TCGA_LUAD group, and TCGA_LUSC group with thresholds of |log2FC| > 2, average expression > 2, and adjust P-value < 0.05, respectively. The red dots and blue dots represent the up-regulated and down-regulated DELs, separately. d The intersection of DELs in three groups. e The top 10 up and down DELs identified in three groups.
