Review: Hypoxic and oxidative stress resistance in Drosophila melanogaster

Altered Gravity Induces Oxidative Stress in Drosophila melanogaster

Genome-Wide Association Analysis of Oxidative Stress Resistance in Drosophila melanogaster

BACKGROUND Aerobic organisms are susceptible to damage by reactive oxygen species. Oxidative stress resistance is a quantitative trait with population variation attributable to the interplay between genetic and environmental factors. Drosophila melanogaster provides an ideal system to study the genetics of variation for resistance to oxidative stress. METHODS AND FINDINGS We used 167 wild-der...

Oxidative stress resistance: a robust correlated response to selection in extended longevity lines of Drosophila melanogaster?

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control li...

Oxidative 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...

Aconitase and Developmental EndPointsasEarly IndicatorsofCellularToxicity Induced by Xenobiotics in Drosophila Melanogaster

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system.  Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
