Hepatic mitochondrial dysfunction in Friedreich Ataxia
BACKGROUND Mitochondrial dysfunction due to respiratory chain impairment is a key feature in pathogenesis of Friedreich ataxia. Friedreich ataxia affects the nervous system, heart and pancreas. METHODS We assessed hepatic mitochondrial function by (13)C-methionine-breath-test in 16 Friedreich ataxia patients and matched healthy controls. RESULTS Patients exhaled significantly smaller amount...
متن کاملIron and Friedreich ataxia.
Friedreich ataxia is due to insufficient levels of frataxin, a mitochondrial iron chaperone that shields this metal from reactive oxygen species (ROS) and renders it bioavailable as Fe II. Frataxin participates in the synthesis of iron-sulfur clusters (ISCs), cofactors of several enzymes, including mitochondrial and cytosolic aconitase, complexes I, II and III of the respiratory chain, and ferr...
متن کاملFriedreich ataxia: neuropathology revised.
Friedreich ataxia is an autosomal recessive disorder that affects children and young adults. The mutation consists of a homozygous guanine-adenine-adenine trinucleotide repeat expansion that causes deficiency of frataxin, a small nuclear genome-encoded mitochondrial protein. Low frataxin levels lead to insufficient biosynthesis of iron-sulfur clusters that are required for mitochondrial electro...
متن کاملReview: Friedreich Ataxia and Erythropoietin
In vitro and in vivo studies have provided evidence for neuroprotective properties of Erythropoietin in neurodegenerative disorders. Although the magnitude of effect is still controversial, very recent findings point to neuronal protection in the central nervous system by Erythropoietins. Erythropoietin is a powerful growth factor which enhances cellular size and ultimatively increases the numb...
متن کاملFriedreich ataxia in Norway – an epidemiological, molecular and clinical study
BACKGROUND Friedreich ataxia is an autosomal recessive hereditary spinocerebellar disorder, characterized by progressive limb and gait ataxia due to proprioceptive loss, often complicated by cardiomyopathy, diabetes and skeletal deformities. Friedreich ataxia is the most common hereditary ataxia, with a reported prevalence of 1:20 000 - 1:50 000 in Central Europe. Previous reports from south No...
