The peroxisome represents a ubiquitous single membrane-bound key organelle that executes various metabolic pathways such as fatty acid degradation by and -oxidation, ether-phospholipid biosynthesis, metabolism of reactive oxygen species, and detoxification of glyoxylate in mammals. To fulfil this vast array of metabolic functions, peroxisomes accommodate 50 different enzymes at least as identif...

The peroxisome represents a ubiquitous single membrane-bound key organelle that executes various metabolic pathways such as fatty acid degradation by alpha- and beta-oxidation, ether-phospholipid biosynthesis, metabolism of reactive oxygen species, and detoxification of glyoxylate in mammals. To fulfil this vast array of metabolic functions, peroxisomes accommodate approximately 50 different en...

Peroxisomes have long been established to play a central role in regulating various metabolic activities in mammalian cells. These organelles act in concert with mitochondria to control the metabolism of lipids and reactive oxygen species. However, while mitochondria have emerged as an important site of antiviral signal transduction, a role for peroxisomes in immune defense is unknown. Here, we...

We describe an unusual mechanism for organelle division. In the yeast Yarrowia lipolytica, only mature peroxisomes contain the complete set of matrix proteins. These mature peroxisomes assemble from several immature peroxisomal vesicles in a multistep pathway. The stepwise import of distinct subsets of matrix proteins into different immature intermediates along the pathway causes the redistribu...

The oxidation of very long chain fatty acids and synthesis of ether glycerolipids (plasmalogens) occurs mainly in peroxisomes. Zellweger's cerebrohepatorenal syndrome (CHRS) is a rare, inherited metabolic disease characterized by an apparent absence of peroxisomes, an accumulation of very long chain fatty acids, and a decrease of plasmalogens in tissues and cultured fibroblasts from these patie...

Eukaryotic cells have evolved molecular mechanisms to ensure the faithful partitioning of cellular components during cell division. The budding yeast Saccharomyces cerevisiae has to actively deliver about half of its organelles to the growing bud, while retaining the remaining organelles in the mother cell. Until lately, little was known about the inheritance of peroxisomes. Recent studies have...

Peroxisomes are indispensable for human health and development. They represent ubiquitous subcellular organelles which compartmentalize enzymes responsible for several crucial metabolic processes such as β-oxidation of specific fatty acids, biosynthesis of ether phospholipids and metabolism of reactive oxygen species. Peroxisomes are highly flexible organelles that rapidly assemble, multiply an...

We report the utilization of Discosoma sp. red fluorescent protein DsRed to visualize peroxisomes in the filamentous ascomycete Sordaria macrospora. To achieve labeling of peroxisomes, DsRed was fused to a serine-lysine-leucine tag (SKL). Expression of the DsRed-SKL fusion gene under the control of the Aspergillus nidulans gpd-promoter led to protein import of DsRed into peroxisomes. In this st...

Endoplasmic Reticulum (ER) is the largest and one of most complex cellular structures, indicating its widespread importance variety functions, including synthesis membrane secreted proteins, protein folding, calcium storage, lipid biogenesis. Moreover, ER implicated in cholesterol, plasmalogen, phospholipid, sphingomyelin biosynthesis. Furthermore, contact with organelles, such as mitochondria,...

The effect of gemfibrozil on the fine structure of peroxisomes across the rat liver lobule was investigated by light and electron microscopy using the alkaline diaminobenzidine (DAB) medium for the visualization of catalase peroxidatic activity. The oral administration of gemfibrozil for 2 weeks induces a striking heterogeneity in the lobular distribution of peroxisomes. The size and shape of p...
