Effects of reactive oxygen and nitrogen metabolites on eotaxin-induced eosinophil chemotactic activity in vitro.
Peroxynitrite, an oxidant generated by the interaction between superoxide and nitric oxide (NO), has been implicated in the etiology of numerous disease processes. Several studies have shown that peroxynitrite-induced protein nitration may compromise enzyme and protein function. We hypothesized that peroxynitrite may regulate cytokine function during inflammation. To test this hypothesis, the e...
متن کاملEffects of reactive oxygen and nitrogen metabolites on MCP-1-induced monocyte chemotactic activity in vitro.
Peroxynitrite, an oxidant generated by the interaction between superoxide and nitric oxide (NO), can nitrate tyrosine residues, resulting in compromised protein function. Monocyte chemoattractant protein-1 (MCP-1) is a chemokine that attracts monocytes and has a tyrosine residue critical for function. We hypothesized that peroxynitrite would alter MCP-1 activity. Peroxynitrite attenuated MCP-1-...
متن کاملBioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders. Sensitive and specific detection methods for ROS and RNS in biological samples should be useful for elucidation of biologi...
متن کاملBiochemistry of Reactive Oxygen and Nitrogen Species
Reactive species or free radicals include reactive oxygen and nitrogen species that are called reactive oxygen nitrogen species. Reactive oxygen species are formed as a natural by-product of the normal metabolism of oxygen and have significant roles in cell signaling and homeostasis. The reactive oxygen species are generated as a byproduct of biochemical reactions, in mitochondria, peroxisomes,...
متن کاملRole of Caspases and Reactive Oxygen Species in Rose Bengal-Induced Toxicity in Melanoma Cells
Objective We have previously shown that Rose Bengal (RB) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. To clarify RB-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ROS) were studied in melanoma cells. Material and Methods Human melanoma cell lines, Me 4405 and Sk-Mel-28 were cultured in DM...
