Figure 2. Identification of recurrence-associated lncRNAs in CRC patients. (A) The heatmap of recurrence-associated lncRNAs identified by high-throughput human genome-wide lncRNA microarray; (B) The heatmap of Recurrence-associated lncRNAs detected by RT-qPCR. (C) The differentially expressed lncRNAs between recurrence group and nonrecurrence group; *P<0.05, **P<0.01, ***P<0.001 [Mann–Whitney U test].
