MT-CO1 and Alzheimer disease: Observed in the left side of Figure 7, major networks of cellular/biochemical pathways/phenotypes (and their associated proteins) possibly affected in the mild AD vs. control IPA comparison include the AD, dementia, amyloidosis, and autoimmunity related proteins mitochondrial (MT) NADH dehydrogenase subunit 6 [MT-ND6], MT-ND1 (NADH dehydrogenase subunit 1), and MT-CO1 (Cytochrome c oxidase subunit 1).
