Histone deacetylase inhibitors reverse gene silencing in Friedreich's ataxia

Abstract

Expansion of GAA x TTC triplets within an intron in FXN (the gene encoding frataxin) leads to transcription silencing, forming the molecular basis for the neurodegenerative disease Friedreich's ataxia. Gene silencing at expanded FXN alleles is accompanied by hypoacetylation of histones H3 and H4 and trimethylation of histone H3 at Lys9, observations that are consistent with a heterochromatin-mediated repression mechanism. We describe the synthesis and characterization of a class of histone deacetylase (HDAC) inhibitors that reverse FXN silencing in primary lymphocytes from individuals with Friedreich's ataxia. We show that these molecules directly affect the histones associated with FXN, increasing acetylation at particular lysine residues on histones H3 and H4 (H3K14, H4K5 and H4K12). This class of HDAC inhibitors may yield therapeutics for Friedreich's ataxia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
