Screening of DE lncRNAs and mRNAs between LUAD tissues and normal tissues. A Heatmap of DE lncRNAs; B Heatmap of DE mRNAs; the x axis shows samples and the y axis shows DE genes. Red and blue represent upregulated and downregulated genes, respectively. C Scatter and volcano plots showing the expression profiles of DE lncRNAs based on the lncRNAs expression values detected by microarray. D Scatter and volcano plots showing expression profiles of DE mRNAs based on the expression values of mRNAs detected by microarray; |FC|≥ 2.0, P < 0.05. E Heatmap of DE lncRNAs in 512 LUAD tissue samples and 59 adjacent tissue samples. Green and red represent downregulated and upregulated lncRNAs, respectively. F Volcano plot of the 1271 upregulated lncRNAs and 645 downregulated lncRNAs that were screened (|log2FC|> 1, P < 0.05). G Venn diagram of DE lncRNAs identified by the TCGA and microarray analyses
