COX5B and neurodegenerative disease: Genes encoding for the subunits of mitochondrial ATP synthase (e.g., ATP5B, ATP5G3, ATP5J, and ATP5C1), cytochrome c oxidase (e.g., COX5A, COX5B, and COX6C), succinate dehydrogenase (e.g., SDHB, SDHC), NADH dehydrogenase (ubiquinone), (e.g., NDUFA8, NDUFA9, NDUFB5, and NDUFS1), and the ubiquinol-cytochrome c oxidoreductase (e.g., UQCRB, UQCRC1, and UQCRH) were deregulated in different datasets and highlighted KEGG pathways are involved in neurodegenerative diseases such as AD, HD, and PD.
