Lead induces oxidative stress and phenotypic markers of apoptosis in Saccharomyces cerevisiae

Signalling Oxidative Stress in Saccharomyces cerevisiae

Cadmium-induced oxidative stress in Saccharomyces cerevisiae.

The present study was undertaken to determine the effect of cadmium (Cd) on the antioxidant status of the yeast Saccharomyces cerevisiae. S. cerevisiae serves as a good eukaryotic model system for the study of the molecular mechanisms of oxidative stress. We investigated the adaptative response of S. cerevisiae exposed to Cd. Yeast cells could tolerate up to 100 microM Cd and an inhibition in t...

Ichthyotoxic Cochlodinium polykrikoides Induces Mitochondrial Mediated Oxidative Stress and Apoptosis in Rat Liver Hepatocytes

In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...

Busulfan induces oxidative stress- and Bcl-2 family gene-related apoptosis in epididymal sperm and testis of adult male mice

Introduction: Busulfan as a chemotherapeutic agent causes testicular germinal epithelium depletion and cytotoxicity in germ cells. The aim of this study was to assess antioxidant status, reactive oxygen species (ROS) generation and apoptosis-related genetic markers of adult male mouse sperm following busulfan treatment. Materials and Methods: Forty adult NMRI mice (30 ± 5 g) were divided...
