Frataxin‐deficient neurons and mice models of Friedreich ataxia are improved by TAT‐MTScs‐FXN treatment
Friedreich ataxia (FA) is a rare disease caused by deficiency of frataxin, a mitochondrial protein. As there is no cure available for this disease, many strategies have been developed to reduce the deleterious effects of such deficiency. One of these approaches is based on delivering frataxin to the tissues by coupling the protein to trans-activator of transcription (TAT) peptides, which enable...
متن کاملExonic deletions of FXN and early-onset Friedreich ataxia.
BACKGROUND Friedreich ataxia (FA) is the most frequent type of autosomal recessive cerebellar ataxia, occurring at a mean age of 16 years. Nearly 98% of patients with FA present with homozygous GAA expansions in the FXN gene. The remaining patients are compound heterozygous for an expansion and a point mutation. Patients who are compound heterozygous for an exonic deletion and an expansion are ...
متن کاملAssembly and iron-binding properties of human frataxin, the protein deficient in Friedreich ataxia.
Friedreich ataxia (FRDA) is an autosomal recessive degenerative disease caused by a deficiency of frataxin, a conserved mitochondrial protein of unknown function. Mitochondrial iron accumulation, loss of iron-sulfur cluster-containing enzymes and increased oxidative damage occur in yeast and mouse frataxin-depleted mutants as well as tissues and cell lines from FRDA patients, suggesting that fr...
متن کاملRescue of the Friedreich Ataxia Knockout Mutation in Transgenic Mice Containing an FXN-EGFP Genomic Reporter
Friedreich ataxia (FRDA) is an autosomal recessive disorder characterized by neurodegeneration and cardiomyopathy. The presence of a GAA trinucleotide repeat expansion in the first intron of the FXN gene results in the inhibition of gene expression and an insufficiency of the mitochondrial protein frataxin. We previously generated BAC-based transgenic mice containing an FXN-EGFP genomic reporte...
متن کاملGenetic Variations Creating MicroRNA Target Sites in the FXN 3′-UTR Affect Frataxin Expression in Friedreich Ataxia
Friedreich's ataxia (FRDA) is a severe neurodegenerative disease caused by GAA repeat expansion within the first intron of the frataxin gene. It has been suggested that the repeat is responsible for the disease severity due to impaired transcription thereby reducing expression of the protein. However, genotype-phenotype correlation is imperfect, and the influence of other gene regions of the fr...
