Reactive Oxygen Species (ROS)

Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.

ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

    Argininosuccinic acid disodium
    Inducer
    Argininosuccinic acid disodium is an intermediate metabolite in the urea cycle, and its level is associated with argininosuccinic aciduria. Argininosuccinic acid disodium can induce oxidative stress, leading to lipid and protein oxidation, reduction of glutathione, and decrease in antioxidant enzyme activity. Argininosuccinic acid disodium can be converted into guanidinosuccinic acid, a nitric oxide mimic, under the action of nitric oxide-derived free radicals. Argininosuccinic acid disodium can be used in the research of metabolic diseases, renal failure, nervous system diseases, etc.
