Prognostic Correlation of an Autophagy-Related Gene Signature in Patients with Head and Neck Squamous Cell Carcinoma

Figure 2

Differentially expressed autophagy-related genes (ARGs). (a) The heat maps of the 38 differently expressed ARGs. The red color indicates high gene expression while the green color indicates low gene expression. N indicates nontumor tissues; T indicates tumor tissues. (b) The volcano plot for the 232 ARGs from TCGA database. Red indicates high expression, and green indicates low expression. Black indicates that those genes show no difference between HNSCC and paired nontumor tissues. (c) The boxplot of the differentially expressed ARGs.
