Abstract

X‐linked adrenoleukodystrophy (X‐ALD) is a neurodegenerative disease due to a defect in the ABCD1 (ALD) gene. ABCD1, and the two close homologues ABCD2 (ALDR) and ABCD3 (PMP70), are genes encoding ATP‐binding cassette half‐transporters of the peroxisomal membrane. As overexpression of the ABCD2 or ABCD3 gene can reverse the biochemical phenotype of X‐ALD (reduced β‐oxidation of very‐long‐chain fatty acids), pharmacological induction of these partially redundant genes may represent a therapeutic approach to X‐ALD. We previously reported that the ABCD2 and ABCD3 genes could be strongly induced by fibrates, which are hypolipidaemic drugs and peroxisome‐proliferators in rodents. We provide evidence that the induction is dependent on peroxisome proliferator‐activated receptor (PPARα) as both genes were not induced in fenofibrate‐treated PPARα–/– knock‐out mice. To further characterize the PPARα pathway, we cloned and analysed the promoter of the ABCD2 gene, the closest homologue of the ABCD1 gene. The proximal region (2 kb) of the rat promoter displayed a high conservation with the human and mouse cognate sequences suggesting an important role of the region in regulation of the ABCD2 gene. Classically, fibrate‐induction involves interaction of PPARα with a response element (PPRE) characterized by a direct repeat of the AGGTCA‐like motif. Putative PPRE motifs of the rat ABCD2 promoter were studied in the isolated form or in their promoter context by gel‐shift assay and transfection of COS‐7 cells. We failed to characterize a functional PPRE, suggesting a different mechanism for the PPARα‐dependent regulation of the ABCD2 gene.

  • Pharmacological induction of ABCD2 was shown to compensate for ABCD1 defect in vitro and in rare cases in vivo.

    “Pharmacological induction of ABCD2 was indeed shown to compensate for ABCD1 defect in vitro and in rare cases, in vivo, opening the way for clinical trials [ 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ].”

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.
