متن کاملMitochondrial reactive oxygen species and Ca2+ signaling.
Mitochondria are an important source of reactive oxygen species (ROS) formed as a side product of oxidative phosphorylation. The main sites of oxidant production are complex I and complex III, where electrons flowing from reduced substrates are occasionally transferred to oxygen to form superoxide anion and derived products. These highly reactive compounds have a well-known role in pathological...
متن کاملMitochondrial reactive oxygen species and cancer
Mitochondria produce reactive oxygen species (mROS) as a natural by-product of electron transport chain activity. While initial studies focused on the damaging effects of reactive oxygen species, a recent paradigm shift has shown that mROS can act as signaling molecules to activate pro-growth responses. Cancer cells have long been observed to have increased production of ROS relative to normal ...
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 کاملMitochondrial 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...
