Figure 2A displays a volcano plot of the DE genes. By overlapping lncRNAs identified via GEO2R with our experimental data through Venn diagram analysis, we identified seven commonly dysregulated candidates (HOTAIRM1, HAND2-AS1, ADAMTS9-AS2, EMX2OS, WT1-AS, MIR31HG, and MEG3) (Figure 2B). EMX2OS, WT1-AS, and MIR31HG were subsequently excluded due to non-significant differential expression (P > 0.01) between tumor and normal tissues in the TCGA BRCA dataset. The gene discussed is MIR31HG; the disease is neoplasm.
