DiseasesOS/MDF hallmarksReferences

A. neurologic diseases
 Alzheimer’s DiseaseAberrations in OXPHOS and Krebs cycle; altered mt-associated endoplasmic[134141]
reticulum membranes as related to amyloid precursor protein; dysregulated Fe
metabolism; HNE- induced oxidation of lipoic acid; ↓ lipoamide dehydrogenase in
brain of AD patients and of AD mice; ↓ Complexes III and IV; mitochondrial mass
 Amyotrophic lateral sclerosisprotein misfolding at endoplasmic reticulum (ER); altered Golgi network; oxidative[142146]
damage to ER proteins; ↓ WBC glutathione peroxidase; ↓ SOD-1 related to disease
progression; ↓ NADPH oxidase; ↓ complex I and ATP/ADP ratio; abnormal mt ultrastructure
 Epilepsy↑ NOS II with NO-, and ONOO dependent ↓ complex I activity; ↑ complex[147150]
III-dependent production of brain mitochondria; ↓ lipoic acid synthetase
 Myalgic encephalomyelitis/
 /chronic fatigue syndrome
↑ urinary 8-OHdG; ↑ TBARS; ↓ Vit C; ↓ HSP70; ↑ plasma peroxides and oxidized[151156]
LDL; ↓ CoQ10; ↑ ATP production; ↑ complex I, III and IV
 Multiple sclerosis↑ lipid hydroperoxide, carbonyl protein, and NO metabolites; ↓ total radical-trapping[157160]
antioxidant parameter; Melatonin-induced ↑ SOD and ↑ GPx, and ↓ MDA; ↓ OXPHOS
activity; mtDNA deletions
 Parkinson’s disease↑ lipid peroxides; ↑ urinary 8-OHdG; ↑ plasma F(2)-IsoPs, HETEs, 7beta-and[6, 161165]
27-hydroxycholesterol, 7-ketocholesterol, F(4)-NPs; dysregulated Fe metabolism
↓ CoQ10, and ↓ complex V; ↑↓ cysteine oxidation within complex I; ↑ lactate

B. psychiatric diseases
 Autistic spectrum disorders↓ GSH/GSSG in WBC; ↑ 4-hydroxynonenal in plasma and RBC membranes;[166172]
↑ 3-nitrotyrosine and 8-OHdG; downregulated OXPHOS (↓ complex I, III, IV and
V); ↓ aconitase; ↑ mtDNA deletions, GC→AT transitions, and GC→TA transitions
 Bipolar disorder↓ attachment of hexokinase 1 to outer mt membrane;[173175]
↓ GSH/GSSG; ↓ CAT expression;
 Major depressionaltered IL-6, IL-10, and IL-6/IL-10 ratio versus F2-isoprostanes; ↑ protein[176179]
carbonylation and glutathione reductase expression; ↑ SOD, CAT and PER
↑ PMNs apoptosis (cytochrome c release); ↓ complex I subunits
 Obsessive-compulsive disorder↑ MDA/TBARS; ↑ SOD; ↓ GSH/GSSG; prevailing CC (Ala/Ala) SOD-2 genotype[180182]
 Schizophrenia↑ lipid peroxidation, damage to proteins, and DNA; ↓ antioxidant levels (CoQ10,[183187]
Vit E, GSH and melatonin); autoimmune responses; ↑ TBARS, IL-6 and PCC levels;
↓ TRX levels; ↓ plasma total antioxidant status
