Peroxisomes and oxidative stress.
The discovery of the colocalization of catalase with H2O2-generating oxidases in peroxisomes was the first indication of their involvement in the metabolism of oxygen metabolites. In past decades it has been revealed that peroxisomes participate not only in the generation of reactive oxygen species (ROS) with grave consequences for cell fate such as malignant degeneration but also in cell rescu...
متن کاملOxidative stress in experimental liver microvesicular steatosis: role of mitochondria and peroxisomes.
BACKGROUND Hepatic microvesicular steatosis is a clinical manifestation seen in a number of liver diseases. Although the role of mitochondrial beta-oxidation in the development of the disease has been well studied, information on lipid peroxidative damage in liver subcellular organelles is scarce. The present study looked at oxidative stress in hepatic peroxisomes and microsomes in microvesicul...
متن کاملPlant peroxisomes: A nitro-oxidative cocktail
Although peroxisomes are very simple organelles, research on different species has provided us with an understanding of their importance in terms of cell viability. In addition to the significant role played by plant peroxisomes in the metabolism of reactive oxygen species (ROS), data gathered over the last two decades show that these organelles are an endogenous source of nitric oxide (NO) and...
متن کاملOxidative decarboxylation of glycollate and glyoxylate by leaf peroxisomes.
1. The conditions under which peroxisomal preparations from leaves of spinach beet and spinach catalyse the release of (14)CO(2) from [1-(14)C]glycollate and [1-(14)C]glyoxylate were investigated. 2. At pH8, (14)CO(2) production from [1-(14)C]glyoxylate was accompanied by equivalent quantities of formate. The accumulation of oxalate and the effects of various reagents, especially catalase inhib...
متن کاملOxidative Stress and Human Disease: a Review
Background: The human body needs both types of oxidants (free radicals) and antioxidants for normal metabolism, signal transduction mechanism, and the order of cellular activity. Free radicals can be either harmful or helpful to the body, in fact, they play a dual role as both toxic and beneficial compounds. The human body has the natural antioxidant defense mechanism to counteract the free rad...
