• When compared to the stressed seedlings, mitochondrial oxygen uptake from seedlings of Se (0.75 ppm) group and mimosine (0.2 mM) group exhibited threefold enhancement in state 3 respiration rate and a controlled state 4 rate, with respiratory control ratios of 5-8. (typeset.io)
  • Exposure to Se or mimosine exhibited a differential response in the mitochondrial catalase and ascorbate peroxidase (Asc-Px) activities. (typeset.io)
  • 2011 ). On the other side, plants have developed some enzymatic systems including superoxide dismutases (SOD), catalases (CAT), ascorbate peroxidases (APX), peroxiredoxins and non-enzymatic mechanisms to protect against oxidative damage caused by these ROS (Agrawal et al. (springeropen.com)
  • The soluble activity in mimosine groups increased twofold, but only by 75% in Se groups. (typeset.io)
  • Peroxidase activity registered a significant increase by threefold in mitochondria and fourfold in soluble fraction in both Se and mimosine groups. (typeset.io)
  • They, however, also contained higher intracellular GSH levels and catalase than mesothelioma cells and had elevated levels of γ-glutamylcysteine synthetase (γGCS). (charismaticplanet.com)
  • It is thought that catalase-peroxidase provides protection to cells under oxidative stress. (wikipedia.org)
  • Mesothelioma cell line expressing the highest MnSOD (10 fold compared to non-malignant mesothelial cells) levels also had the highest levels of GSH, glutathione S-transferase (GST), and catalase, and was the most resistant cell line to oxidants and cytotoxic drugs. (charismaticplanet.com)
  • The role of GSH and catalase were also investigated by treating the Malignant Pleural Mesothelioma cells and A549 adenocarcinoma cells with buthionine sulfoximine (BSO), to block glutathione synthesis, and aminotriazole (ATZ) to inhibit catalase. (charismaticplanet.com)
