Peroxisomal β-oxidation in X-linked adrenoleukodystrophy
Background: ABCD1 is a peroxisomal ABC transporter whose dysfunction causes X-linked adrenoleukodystrophy (X-ALD). Results: β-Oxidation of C26:0 as well as C22:0 acyl-CoA esters is impaired in X-ALD. ABCD3 accounts for residual β-oxidation activity in XALD fibroblasts. Conclusion: ABCD1 mediates very long-chain acyl-CoA ester β-oxidation without need for additional re-esterification by an acyl-...
متن کاملInflammation in X - linked Adrenoleukodystrophy
Project Description: Cells compute by processing external stimuli according to their internal state, abiding to rules that remain poorly understood (Rubens et al., 2016). Cell fate decisions are the key for constructing a multicellular organism. Errors, bias or aberrant delays in making such decisions can lead to neoplasia or in extreme cases, tumorigenesis. Our key question is how cells make d...
متن کاملMRI in X-linked adrenoleukodystrophy.
A 45-year-old man with no medical history presented with behavioral changes. He was withdrawn from his family and friends. Home and finances had fallen into disorder. He was disheveled and incontinent of urine and feces. He lacked insight into his cognitive decline. His skin was bronzed and the examination was notable only for upgoing plantar responses. Peroxisomal fatty acid profile was elevat...
متن کاملPathophysiology of X-linked adrenoleukodystrophy☆
Currently the molecular basis for the clinical heterogeneity of X-linked adrenoleukodystrophy (X-ALD) is poorly understood. The genetic bases for all different phenotypic variants of X-ALD are mutations in the gene encoding the peroxisomal ATP-binding cassette (ABC) transporter, ABCD1 (formerly adrenoleukodystrophy protein, ALDP). ABCD1 transports CoA-activated very long-chain fatty acids from ...
متن کاملBezafibrate for X-Linked Adrenoleukodystrophy
UNLABELLED X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene and is characterized by impaired beta-oxidation of very-long-chain fatty acids (VLCFA) and subsequent VLCFA accumulation in tissues. In adulthood X-ALD most commonly manifests as a gradually progressive myelopathy, (adrenomyeloneuropathy; AMN) without any curative or disease modifying treatments. We recent...
