(A) This figure illustrates the overall workflow of the study; (B) shows the differential gene expression between solid tumors and adjacent normal tissues in TCGA; (C) displays the intersection of differentially expressed genes from various tumors with the 1,134 mitochondrial function genes from the MitoCarta3.0 database; (D) presents the mitochondrial function-related differentially expressed genes identified after intersecting solid tumors with adjacent normal tissues in TCGA, highlighting the significance of mitochondrial function differences across various tumor types; (E) illustrates the upregulated and downregulated differentially expressed genes across different tumor sites, revealing the expression patterns of mitochondrial-related genes in various cancers; (F) shows the GO analysis of commonly upregulated and downregulated genes.
