SFXN4 and hepatocellular carcinoma: We found that biological processes (BP), including GO:0042776 (mitochondrial ATP synthesis coupled proton transport), GO:0032543 (mitochondrial translation), GO:0009060 (aerobic respiration), GO:0032981 (mitochondrial respiratory chain complex I assembly), GO:0015986 (ATP synthesis coupled proton transport), GO:0006120 (mitochondrial electron transport, NADH to ubiquinone) were significantly regulated by SFXN4 in HCC (Figure 4C).
