The Expression Landscape of lncRNAs in CCA

(A) Overall distribution of lncRNA expression in CCA patients. (B) Detected sample distribution of lncRNAs with different expression levels in CCA samples. (C) Heatmap shows the expression variations of differentially expressed lncRNAs between CCA tumor and paired normal samples derived from the TCGA dataset. (D) Scatterplot shows the expression difference (tumor vs. normal fold change) and significance of survival difference (log-rank test p value) of differentially expressed lncRNAs. Red dots represent upregulated lncRNAs, blue dots represent downregulated lncRNAs, and purple dots represent lncRNAs that showed significant survival difference between high- and low-expression samples.
