Localization of nervonic acid beta-oxidation in human and rodent peroxisomes: impaired oxidation in Zellweger syndrome and X-linked adrenoleukodystrophy.
Studies with purified subcellular organelles from rat liver indicate that nervonic acid (C24:1) is beta-oxidized preferentially in peroxisomes. Lack of effect by etomoxir, inhibitor of mitochondrial beta-oxidation, on beta-oxidation of lignoceric acid (C24:0), a peroxisomal function, and that of nervonic acid (24:1) compared to the inhibition of palmitic acid (16:0) oxidation, a mitochondrial f...
متن کاملPeroxisomal 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 کاملProfiles of very-long-chain fatty acids in plasma, fibroblasts, and blood cells in Zellweger syndrome, X-linked adrenoleukodystrophy, and rhizomelic chondrodysplasia punctata.
Profiles of saturated very-long-chain (> C22) fatty acids were studied in plasma, fibroblasts, erythrocytes, platelets, and leukocytes of patients affected by peroxisomal disorders such as Zellweger syndrome, X-linked adrenoleukodystrophy (X-ALD), and classic rhizomelic chondrodysplasia punctata (RCDP) and in controls. In Zellweger patients, the concentration of hexacosanoic acid (C26:0) and th...
متن کاملGuillain Barré Syndrome in a Child With X-Linked Adrenoleukodystrophy
X-Linked adrenoleukodystrophy is the most common peroxisomal disorder with different phenotypes among patients carrying the same ABCD1 mutation. There were previously reported associations of X-linked adrenoleukodystrophy with autoimmune disorders. The authors describe Guillain Barré syndrome in a child with X-linked adrenoleukodystrophy. The available evidence does not permit conclusion concer...
