Figure 1. Differentially expressed genes (DEGs) related to mitophagy were identified between cancer and normal tissue. (A) Heatmap of mitophagy-related genes (MRGs) expression profiles. (B) Boxplots of the expression of DEGs. (C) Protein-protein interaction (PPI) network of DEGs. (D) Correlation network of DEGs. Red represents positive correlations while blue represents negative correlations. *p < 0.05; **p < 0.01; ***p < 0.001.
