Figure 2A illustrates some of the numerous differentially expressed lncRNAs in the whole-blood samples from LC patients compared with the healthy group. According to the analysis of the microarray and data summarization, ENST00000602692.1, ENST00000589723.1, lnc-CTA-250D10.23, ENST00000527317.2, TCONS_00023502, and lnc-TCL6 were identified as candidate biomarkers with significantly higher expression levels in the LC group than in the healthy group (fold changes = 3.35, 3.67, 2.43, 2.07, 2.05, and 3.36, respectively, P < 0.05; Figure 2B). This evidence concerns the gene TCL6 and laryngotracheoesophageal cleft.
