Annual Review of Cell and Developmental Biology, 2001
▪ Abstract Fifteen years ago, we had a model of peroxisome biogenesis that involved growth and division of preexisting peroxisomes. Today, thanks to genetically tractable model organisms and Chinese hamster ovary cells, 23 PEX genes have been cloned that encode the machinery (“peroxins”) required to assemble the organelle.

Peroxisomes, lipid metabolism, and peroxisomal disorders
Molecular Genetics and Metabolism, 2004Peroxisomes catalyse a large variety of different cellular functions of which most have to do with lipid metabolism. This paper deals with the role of peroxisomes in three key pathways of lipid metabolism, including: (1) etherphospholipid biosynthesis, (2) fatty acid beta-oxidation, and (3) fatty acid alpha-oxidation.

Peroxisomal diseases are a group of genetically and clinically divergent diseases due to defects in either the biogenesis of peroxisomes (group 1) or one of its metabolic functions (group 2). Zellweger syndrome and X-linked adrenoleukodystrophy (XALD) are the prototypes for group 1 and 2, respectively.

The peroxisomal disorders represent a group of genetic diseases in man in which there is an impairment in one or more peroxisomal functions. The peroxisomal disorders are subdivided into three subgroups comprising: (1) the peroxisome biogenesis disorders (PBDs); (2) the single peroxisomal (enzyme-) protein deficiencies; and (3) the single peroxisomal ...

Trends in Cell Biology, 2007
Peroxisomes are a dynamic compartment in almost all eukaryotic cells and have diverse metabolic roles in response to environmental changes and cellular demands. The accompanying changes in enzyme content or abundance of peroxisomes are accomplished by dynamically operating membrane- and matrix-protein transport machineries. This review discusses recent

The Cytoplasm: Peroxisomes and Peroxisomal Diseases
2015Peroxisomes are ubiquitous organelles that contain catalase and oxidative enzymes producing H2O2. Depending on cell type, their number, shape, and size vary. By electron microscopy, peroxisomes have a single membrane that encloses a dense matrix that contains a crystalloid core in some species (e.g., rat hepatocytes) but not in others (e.g., human ...

Peroxisomes and Photomorphogenesis
2013In higher plants, light-grown seedlings exhibit photomorphogenesis, a developmental program controlled by a complex web of interactions between photoreceptors, central repressors, and downstream effectors that leads to changes in gene expression and physiological changes. Light induces peroxisomal proliferation through a phytochrome A-mediated pathway,

The concept that there are human disease states that are associated with abnormal peroxisomal function is of recent origin. This is due in part to the relatively recent discovery of the organelle itself by de Duve in 1983, and to the earlier belief that it was a vestigial structure in mammals.

Peroxisome biogenesis conceptually consists of the (a) formation of the peroxisomal membrane, (b) import of proteins into the peroxisomal matrix and (c) proliferation of the organelles. Combined genetic and biochemical approaches led to the identification of 25 PEX genes-encoding proteins required for the biogenesis of peroxisomes, so-called peroxins ...

Gluconeogenesis and the peroxisome
Molecular and Cellular Biochemistry, 1997In this article, the capabilities of peroxisomal involvement in the gluconeogenetic processes of vertebrate animals are reviewed in the light of recent findings on peroxisomal metabolism and proliferation. It is demonstrated that the participation of this organelle affords the potential of alternative pathways for the conversion of triacylglycerols to ...
