Catalase; Glutathione; Lens epithelial cells; Mesenchymal transition; Reactive oxygen species; Transforming growth factor beta 2

This study aimed to discuss the effect and mechanism of glutathione (GSH) and catalase (CAT) on transforming growth factor beta (TGF-β)-induced lens epithelial cell (LEC) apoptosis and epithelial mesenchymal transition (EMT) to prevent and control cataracts. Healthy rabbits (4 weeks old) were randomly selected, and LECs from their lenses were cultured in vitro. The 2nd- and 3rd- ... more

Familial Mediterranean fever; Gene polymorphism; Glutathione peroxidase; Inflammation; Oxidative stress; Paraoxonase

Familial Mediterranean fever (FMF) is an autosomal recessive disorder and is the most frequent of the periodic febrile inflammatory syndromes. The pathogenesis of the disease is not completely understood, even though the FMF gene has been identified. Oxidative stress and inflammation may play a role in the pathogenesis of FMF. We investigated gene polymorphisms of the antioxidative ... more

Candida albicans; Glutathione reductase; GRX2; Virulence

Resistance of Candida albicans to reactive oxygen species is thought to enhance its virulence in mammalian hosts. Genes such as SOD1, which encodes the anti-oxidant, superoxide dismutase, are known virulence factors. We disrupted the gene GRX2, which encodes a putative glutathione reductase (glutaredoxin) in C. albicans, and we compared the mutant with an ... more

Glutathione reductase; Mutation breeding; Random amplified polymorphic DNA; Salt tolerance

Salinity is one of the major problems limiting the yield of agricultural products. Radiation mutagenesis is used to improve salt-tolerant mutant plants. In this study, we aimed to improve salt-tolerant mutants of two oriental tobacco varieties. One thousand seeds of each variety (M0) were irradiated with 100, 200, 300, and 400 Gy gamma rays by Cs-137 gamma. In the M1 ... more

Catalase; Polyphenol oxidase; Superoxide dismutase

Seeds collected at different maturation stages vary in physiological quality and patterns of protective antioxidant systems against deterioration. In this study we investigated the expression of genes that codify catalase (CAT), dismutase superoxide (SOD), and polyphenol oxidase (PPO) during the pre- and post-physiological maturation phases in whole seeds and in endosperms and embryos ... more

Oxidative stress; Polymorphism; Sickle cell anemia; Superoxide dismutase

Oxidative stress may be contributory to the pathophy­siology of the abnormalities that underlie the clinical course of sickle cell anemia. We looked for a possible genetic association between the functional polymorphism Ala-9Val in the human Mn-SOD gene and sickle cell anemia. One hundred and twenty-seven patients with sickle cell anemia and 127 healthy controls were recruited into the ... more

Cold stress; Enzyme activity; Lycopersicum esculentum L.; Real-time PCR; Superoxide dismutase; Tomato

The current study was designed to evaluate lipid peroxidation (via malondialdehyde) levels, the superoxide dismutase (SOD) gene expression profile, and SOD enzyme activity in tomato plants (Lycopersicum esculentum L.) subjected to different time periods of cold stress (control, 2, 4, 6, 8, and 10 days). Results revealed that maximum lipid peroxidation occurred in ... more

Apoptosis; Endothelial progenitor cells; Ginkgo biloba extract; Superoxide dismutase

Although ginkgo biloba extract (GBE) was shown to have antioxidant effects, little has been reported on the ability to GBE to help endothelial progenitor cells (EPCs) resist oxidative stress. The present study evaluated the influence of different concentrations of GBE on superoxide dismutase (SOD) and apoptosis of diabetic peripheral blood EPCs. Twenty-five diabetic patients without any ... more

Corynebacterium glutamicum; Oxidative stress; Peptide methionine sulfoxide reductase; Superoxide dismutase

Promoters of genes encoding superoxide dismutase (sodA) and peptide methionine sulfoxide reductase (msrA) from Cory­nebacterium glutamicum were cloned and sequenced. Promoter region analysis of sodA-msrA was unable to identify putative sites of fixed eventual regulators except for possible sites of fixed OxyR and integra­tion host factor. A study of the ... more
