Identification of Immune-Related Risk Signatures for the Prognostic Prediction in Oral Squamous Cell Carcinoma

Figure 5

The epigenetic regulation of the four immune-related genes and pathways associated with immune-related risk stratification. (a) The correlation between the promoter DNA methylation and gene expression levels of TNFRSF4, LCORL, and PLAU. (b) The pathways enriched by the upregulated genes in the high-score group. (c) The expression profiles of genes involved in the pathways. The OSCC samples were ordered by immune-related risk scores. (d) The differential expression levels of PDGFA and PDGFB in the three pairs of OSCC and NATs by the qPCR method.
