Associations between DNA methylation and gene expression in head and neck squamous cell carcinoma (HNSC). (A) Genome-wide plot of smoothed gene-level Pearson correlation coefficients between binary DNA methylation measurements and gene expression for n = 250 HNSC samples. (B) Plot of smoothed gene-level Pearson correlation coefficients between binary DNA methylation measurements and gene expression for n = 250 HNSC samples in chromosome 19. (C – E) Boxplot displays of expression values of select zinc finger genes by DNA methylation status illustrate strong regulation of gene expression by DNA methylation.
