Mitochondrial metabolism of reactive oxygen species.
For a long time mitochondria have mainly been considered for their role in the aerobic energy production in eukaryotic cells, being the sites of the oxidative phosphorylation, which couples the electron transfer from respiratory substrates to oxygen with the ATP synthesis. Subsequently, it was showed that electron transfer along mitochondrial respiratory chain also leads to the formation of rad...
متن کاملMetabolism of Reactive Oxygen Species in the Fetus
Although apoptosis is believed to play an important role in the ontogenetic development of animals, the molecular mechanism that triggers the regression of liver hemopoiesis during the perinatal period is not known. Apoptosis is induced by many factors such as a decrease in growth factors and increased oxygen stress. Since hepatic γ-glutamyl transferase (GT) levels change markedly during the pe...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
متن کاملReactive oxygen species metabolism and plant-fungal interactions.
Fungal interactions with plants can involve specific morphogenetic developments to access host cells, the suppression of plant defenses, and the establishment of a feeding lifestyle that nourishes the colonizer often-but not always-at the expense of the host. Reactive oxygen species (ROS) metabolism is central to the infection process, and the stage-specific production and/or neutralization of ...
متن کاملReactive oxygen species: metabolism, oxidative stress, and signal transduction.
Several reactive oxygen species (ROS) are continuously produced in plants as byproducts of aerobic metabolism. Depending on the nature of the ROS species, some are highly toxic and rapidly detoxified by various cellular enzymatic and nonenzymatic mechanisms. Whereas plants are surfeited with mechanisms to combat increased ROS levels during abiotic stress conditions, in other circumstances plant...
