Reactive Oxygen Species (Ros-Induced) Ros Release
We sought to understand the relationship between reactive oxygen species (ROS) and the mitochondrial permeability transition (MPT) in cardiac myocytes based on the observation of increased ROS production at sites of spontaneously deenergized mitochondria. We devised a new model enabling incremental ROS accumulation in individual mitochondria in isolated cardiac myocytes via photoactivation of t...
متن کامل[Reactive oxygen species signaling and redox homeostasis regulated by 8-nitro-cGMP].
An emerging aspect of redox signaling is the signaling pathway mediated by electrophilic byproducts, such as nitrated cyclic nucleotide (8-nitro-cGMP), generated via reactions of reactive oxygen species (ROS), NO, and their secondary products. We recently clarified that enzymatically-generated hydrosulfide derivatives regulate the metabolism and signaling of 8-nitro-cGMP. Although hydrogen sulf...
متن کاملMitochondrial reactive oxygen species (ROS) and ROS-induced ROS release.
Byproducts of normal mitochondrial metabolism and homeostasis include the buildup of potentially damaging levels of reactive oxygen species (ROS), Ca(2+), etc., which must be normalized. Evidence suggests that brief mitochondrial permeability transition pore (mPTP) openings play an important physiological role maintaining healthy mitochondria homeostasis. Adaptive and maladaptive responses to r...
متن کاملReactive oxygen species and mitochondria: A nexus of cellular homeostasis
Reactive oxygen species (ROS) are integral components of multiple cellular pathways even though excessive or inappropriately localized ROS damage cells. ROS function as anti-microbial effector molecules and as signaling molecules that regulate such processes as NF-kB transcriptional activity, the production of DNA-based neutrophil extracellular traps (NETs), and autophagy. The main sources of c...
متن کاملMeasurement of Reactive Oxygen Species, Reactive Nitrogen Species, and Redox-Dependent Signaling in the Cardiovascular System
e39 Abstract—Reactive oxygen species and reactive nitrogen species are biological molecules that play important roles in cardiovascular physiology and contribute to disease initiation, progression, and severity. Because of their ephemeral nature and rapid reactivity, these species are difficult to measure directly with high accuracy and precision. In this statement, we review current methods fo...
