Reactive oxygen species in oncogenic transformation.
Ever since ROS (reactive oxygen species) were shown to meet the criteria of true signalling molecules, such as regulated production and a specific biological function, many efforts have been made to understand the precise role of ROS. The function of ROS in pathological mechanisms is taking a more and more central role in various fields of biomedical research, including neurobiology, cardiology...
متن کاملAntioxidant protective mechanisms against reactive oxygen species (ROS) generated by mitochondrial P450 systems in steroidogenic cells.
Mitochondrial P450 type enzymes catalyze central steps in steroid biosynthesis, including cholesterol conversion to pregnenolone, 11beta and 18 hydroxylation in glucocorticoid and mineralocorticoid synthesis, C-27 hydroxylation of bile acids, and 1alpha and 24 hydroxylation of 25-OH-vitamin D. These monooxygenase reactions depend on electron transfer from NADPH via FAD adrenodoxin reductase 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...

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...
