We visualized this data using heatmap (Figure 3B) and box plots (Figure 3C) and found that the expression of these lncRNAs differed significantly between HNSCC patients and healthy controls, most lncRNAs are highly expressed in tumor group, except AL121845.4, LINC00852, AF131215.5, AF131215.6, and C5orf66. Here, PITX1-AS1 is linked to neoplasm.
