Peroxisome biogenesis and human peroxisome-deficiency disorders
Peroxisome is a single-membrane-bounded ubiquitous organelle containing a hundred different enzymes that catalyze various metabolic pathways such as β-oxidation of very long-chain fatty acids and synthesis of plasmalogens. To investigate peroxisome biogenesis and human peroxisome biogenesis disorders (PBDs) including Zellweger syndrome, more than a dozen different complementation groups of Chin...
متن کاملdiagnosis of human peroxisomal biogenesis disorders: molecular understanding of peroxisome
peroxisomes are single membrane bound organelles present in a wide variety of eukaryotes from yeast to human, have different functions, two of which are well conserved, i.e. hydrogen peroxide decomposition and fatty acid beta-oxidation. the process of peroxisome biogenesis can be divided into distinct steps including peroxisome membrane assembly, import of matrix proteins and peroxisome prolife...
متن کاملPeroxisome biogenesis disorders
Defects in PEX genes impair peroxisome assembly and multiple metabolic pathways confined to this organelle, thus providing the biochemical and molecular bases of the peroxisome biogenesis disorders (PBD). PBD are divided into two types--Zellweger syndrome spectrum (ZSS) and rhizomelic chondrodysplasia punctata (RCDP). Biochemical studies performed in blood and urine are used to screen for the P...
متن کاملTemperature-sensitive mutation in PEX1 moderates the phenotypes of peroxisome deficiency disorders.
The peroxisome biogenesis disorders (PBDs), including Zellweger syndrome (ZS), neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), are autosomal recessive diseases caused by deficiency of peroxisome assembly as well as malfunction of peroxisomes, where >10 genotypes have been reported. ZS patients manifest the most severe clinical and biochemical abnormalities, while those ...
متن کاملModeling human peroxisome biogenesis disorders in the nematode Caenorhabditis elegans.
Peroxisomes are ubiquitous eukaryotic organelles. The proteins required for peroxisome biogenesis are called peroxins, and mutations in the peroxin genes cause the devastating human developmental syndromes called the peroxisome biogenesis disorders. Our interest is in elaborating the roles that peroxisomes play in Caenorhabditis elegans development, and in establishing an invertebrate model sys...
