Highlights•Superoxide dismutases (SODs) have important regulatory functions in
metabolism, signalling and transcription.•SODs are crucial for cancer cell growth …

Superoxide dismutase (SOD) activity was measured by seven assay methods. The nitrite
method was found to be the best for our SOD assay kit. This method was then modified to …

Formulations of antioxidant enzymes, superoxide dismutase 1 (SOD1, also known as Cu/Zn
SOD) and catalase were prepared by electrostatic coupling of enzymes with cationic block …

Oxidative stress results from an oxidant/antioxidant imbalance, an excess of oxidants, or a
depletion of antioxidants. A considerable body of recent evidence suggests that oxidative …

Manganese superoxide dismutase (MnSOD) is essential for life as dramatically illustrated by
the neonatal lethality of mice that are deficient in MnSOD. In addition, mice expressing only …

Superoxide (O2-) is the compound obtained when oxygen is reduced by one electron. For a
molecule with an unpaired electron, O2-is surprisingly inert, its chief reaction being a …

Oxidative stress (OS) is an imbalance between the formation of reactive oxygen species
(ROS) and antioxidant defense mechanisms. This phenomenon increases with age and …

Studies examining the biochemical characteristics and pharmacological properties of
extracellular superoxide dismutase (EC SOD) have been severely limited because of …

In a recent review of chemical carcinogenesis, Kensler and Trush (157) express the hope
'that an evaluation of the importance of oxygen free radicals in chemical carcinogenesis will …
