The NR2F1‐AS1 is associated with tumor recurrence. (A) Volcano plot of the lncRNA data. The genes with 1.5‐fold or more change and P < 0.05 are marked with color (red: high and blue: low). (B) Heatmap based on the differentially expressed lncRNA probes clustering by recurrence status (1.5‐fold change, P < 0.05). (C) Venn diagram showing that the lncRNA candidates with upregulated in the recurrence status. (D) 5 computationally predicted lncRNAs, which may be associated with tumor recurrence. (E) qPCR validation of NR2F1‐AS1 as the main lncRNA candidate associated with recurrence. Upper whisker: max, and lower whisker: min.
