Antioxidant defense systems of two lipidopteran insect cell lines
Free Radical Biology and Medicine, 2001Spodoptera frugiperda Sf-9 (Sf-9) and Trichoplusia ni BTI-Tn-5B1-4 (Tn-5B1-4) insect cell lines were found to contain unique assemblages of antioxidant enzymes. Specifically, the Sf-9 insect cell line contained Manganese and Copper-Zinc superoxide dismutase (MnSOD and CuZnSOD) for reducing the superoxide radical (O(2)(*-)) to hydrogen peroxide (H(2)O(2)

Age-dependent modifications in rat hepatocyte antioxidant defense systems
Journal of Hepatology, 1997Age-dependent changes in the hepatic antioxidant systems were studied in hepatocytes from newly weaned (21 days) to 30-month-old rats.Biphasic changes were observed in superoxide dismutase (SOD), glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme (ME), in which noticeable decreases were detected in hepatocytes from newly weaned to 6-month-old ...

Chromium (VI) Can Activate and Impair Antioxidant Defense System
Biological Trace Element Research, 2010The changes in glutathione-dependent cycle enzymes and catalase activities under Cr(VI)-induced oxidative stress were investigated in two distinct cell lines: L-41-human epithelial-like cells and HLF-fetal human diploid lung fibroblasts, which differ in tissue origin, proliferation, and antioxidant enzymes activities. The chromium concentrations from 1

Ubiquinone redox cycle as a cellular antioxidant defense system
BioFactors, 1999AbstractUbiquinone (UQ) reductase responsible for reduction of non‐mitochondrial UQ was investigated in rats toward demonstrating an antioxidant role of UQ. In the liver, most of cellular UQ‐10 reductase activity was attributable to a novel NADPH‐UQ reductase in cytosol.

The Role of the Antioxidative Defense System in Papulopustular Acne
The Journal of Dermatology, 2001AbstractAcne vulgaris frequently occurs in the second decade of life. The pathogenesis of the disease is multifactorial. In this study, we aimed to investigate the role of reactive oxygen species in inflammation of acne by determining the activity of antioxidant defense enzymes in leukocytes.

A Secondary Antioxidant Defense Role for Proteolytic Systems
1988Free radicals, and related oxidants, have long been studied as agents of tissue damage. Lipid peroxidation is a well-established example of free radical toxicity, as is oxidative damage to RNA, DNA, and even carbohydrates. In contrast, the reactions of proteins with various radicals/oxidants have not been so extensively studied and it is sometimes ...

Antioxidants: Responses and Importance in Plant Defense System
2020Antioxidants are chemical substances that prevent cell damage during different stress. Antioxidants are found in all the form of foods, including fruits and vegetables. Although oxidation reactions are crucial, this might cause damage to life. Antioxidants (glutathione, vitamin E, C, etc.) and various other enzymes (superoxide dismutase, catalase ...
