Ubiquinone limits oxidative stress in Escherichia coli.
Ubiquinone is an essential redox component of the aerobic respiratory chains of bacteria and mitochondria. It is well established that mammalian ubiquinone can function in its reduced form (ubiquinol) as a lipid-soluble antioxidant preventing lipid peroxidation. The objective of this study was to test the hypothesis that prokaryotic ubiquinone is involved in the defence against oxidative stress...
متن کاملInfluence of exogenous oxidative stress on Escherichia coli cell growth, viability and morphology
The present study attempted to determine the influence of exogenous oxidative stress on the cell viability of Escherichia coli. In this regard, 3mM hydrogen peroxide (H2O2) was added to the late log phase of E. coli culture, and afterwards the phenotype, cell morphology and the ability to form colony forming units (CFU) on agar plates were examined. As expected, a quick phenotypic suppression a...
متن کاملOxidative stress responses in Escherichia coli and Salmonella typhimurium.
Oxidative stress is strongly implicated in a number of diseases, such as rheumatoid arthritis, inflammatory bowel disorders, and atherosclerosis, and its emerging as one of the most important causative agents of mutagenesis, tumorigenesis, and aging. Recent progress on the genetics and molecular biology of the cellular responses to oxidative stress, primarily in Escherichia coli and Salmonella ...
متن کاملOxidative Stress and Antioxidant Defense
Reactive oxygen species (ROS) are produced by living organisms as a result of normal cellular metabolism and environmental factors, such as air pollutants or cigarette smoke. ROS are highly reactive molecules and can damage cell structures such as carbohydrates, nucleic acids, lipids, and proteins and alter their functions. The shift in the balance between oxidants and antioxidants in favor of ...
متن کاملHemolysin from Escherichia coli induces oxidative stress in blood.
Hemolysin (HlyA) produced by some stains of Escherichia coli is considered to be an important virulence factor of those bacteria. On the other hand, reactive oxygen species (ROS) have been reported to be involved in the pathogenesis of different diseases via oxidative stress generation. The purpose of this study was to analyze the capacity of HlyA to induce oxidative stress in whole blood cultu...
