We generated mitochondrial late-onset neurodegeneration (MILON) mice with postnatal disruption of oxidative phosphorylation in forebrain neurons. They develop normally and display no overt behavioral disturbances or histological changes during the first 5 months of life. The MILON mice display reduced levels of mitochondrial DNA and mitochondrial RNA from 2(More)
Heteroplasmic mitochondrial DNA (mtDNA) mutations (mutations present only in a subset of cellular mtDNA copies) arise de novo during the normal ageing process or may be maternally inherited in pedigrees with mitochondrial disease syndromes. A pathogenic mtDNA mutation causes respiratory chain deficiency only if the fraction of mutated mtDNA exceeds a(More)
OBJECTIVE To examine the relationship between fatigue, regional brain atrophy and normal appearing white matter damage in patients with multiple sclerosis. METHODS Primary fatigued (PF) (n, 17) and non-fatigued (NF) (n, 17) patients with relapsing remitting multiple sclerosis and moderate disability were grouped according to their subjective fatigue(More)
