Reactive oxygen species in cell signaling
WebMay 15, 2000 · Signaling is initiated by specific ligand-receptor interactions. Typically, a series of protein kinase intermediates propagate the signal toward nuclear transcription factors. Other signaling pathways must exist to facilitate the H 2 O 2 production observed by several labs [e.g., references [28], [30] ]. WebJan 28, 2024 · Reactive oxygen species (ROS) are single-electron reduction products of a type of oxygen in the body. It is formed by the transition of mitochondria from state III to state IV in a high-oxygen environment and a high-reduction state in the respiratory chain, which causes a large number of electrons to leak out of the cells and reduces the number ...

ROS trigger signal transduction events, such as mitogen-activated protein kinase cascades, eliciting specific cellular responses.
WebReactive oxygen species (ROS), now appreciated for their cellular signaling capabilities, have a dual role in cancer. On the one hand, ROS can promote protumorigenic signaling, facilitating cancer cell proliferation, survival, and adaptation to hypoxia. WebOne type of stress that induces potential activation of MAPK pathways is the oxidative stress caused by reactive oxygen species (ROS). Generally, increased ROS production in a cell leads to the activation of ERKs, JNKs, or p38 MAPKs, but the mechanisms by which ROS can activate these kinases are unclear.
