A peptide derived from TID1S rescues frataxin deficiency and mitochondrial defects in FRDA cellular models [PDF]

Frontiers in Pharmacology
Friedreich’s ataxia (FRDA), the most common recessive inherited ataxia, results from homozygous guanine–adenine–adenine (GAA) repeat expansions in intron 1 of the FXN gene, which leads to the deficiency of frataxin, a mitochondrial protein essential for ...

Human frataxin, the Friedreich ataxia deficient protein, interacts with mitochondrial respiratory chain

Cell Death and Disease, 2023
Friedreich ataxia (FRDA) is a rare, inherited neurodegenerative disease caused by an expanded GAA repeat in the first intron of the FXN gene, leading to transcriptional silencing and reduced expression of frataxin.

The smoothened agonist SAG reduces mitochondrial dysfunction and neurotoxicity of frataxin-deficient astrocytes

Journal of Neuroinflammation, 2022
Background Friedreich’s ataxia is a rare hereditary neurodegenerative disease caused by decreased levels of the mitochondrial protein frataxin. Similar to other neurodegenerative pathologies, previous studies suggested that astrocytes might contribute to

In vivo overexpression of frataxin causes toxicity mediated by iron-sulfur cluster deficiency

Molecular Therapy: Methods & Clinical Development, 2022
Friedreich's ataxia is a rare disorder resulting from deficiency of frataxin, a mitochondrial protein implicated in the synthesis of iron-sulfur clusters.

Pathological frataxin deficiency in mice causes tissue-specific alterations in iron homeostasis [PDF]

iScience
Summary: Friedreich ataxia is caused by partial frataxin deficiency due to genetic mutations. It is well established that frataxin knockout affects iron homeostasis, but the alterations caused by pathological (partial) frataxin deficiency are poorly ...

PPAR gamma agonist leriglitazone improves frataxin-loss impairments in cellular and animal models of Friedreich Ataxia

Neurobiology of Disease, 2021
Friedreich ataxia (FRDA), the most common autosomal recessive ataxia, is characterized by degeneration of the large sensory neurons and spinocerebellar tracts, cardiomyopathy, and increased incidence in diabetes.

Simultaneous Quantification of Mitochondrial Mature Frataxin and Extra-Mitochondrial Frataxin Isoform E in Friedreich’s Ataxia Blood

Frontiers in Neuroscience, 2022
Friedreich’s ataxia (FRDA) is an autosomal recessive disease caused by an intronic guanine-adenine-adenine (GAA) triplet expansion in the frataxin (FXN) gene, which leads to reduced expression of full-length frataxin (1–210) also known as isoform 1. Full-

Frataxin deficiency alters gene expression in Friedreich ataxia derived IPSC‐neurons and cardiomyocytes

Molecular Genetics & Genomic Medicine, 2023
Background Friedreich's ataxia (FRDA) is an autosomal recessive disease, whereby homozygous inheritance of an expanded GAA trinucleotide repeat expansion in the first intron of the FXN gene leads to transcriptional repression of the encoded protein ...

DNA methylation in Friedreich ataxia silences expression of frataxin isoform E

Scientific Reports, 2022
Epigenetic silencing in Friedreich ataxia (FRDA), induced by an expanded GAA triplet-repeat in intron 1 of the FXN gene, results in deficiency of the mitochondrial protein, frataxin.
