Reactive Oxygen Species (ROS)
Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

Triphenyl phosphate-d15
0 ImagesSynonyms: Celluflex TPP-d15; DHPF 005-d15; Disflamol TP-d15; Disflamoll TP-d15; NSC 57868-d15; Phenyl phosphate ((PhO)3PO)-d15; Phoscon FR 903N-d15Triphenyl phosphate-d15 is the deuterium labeled Triphenyl phosphate. Triphenyl phosphate is an orally active, blood-brain barrier-permeable aryl organophosphate flame retardant and endocrine disruptor. Triphenyl phosphate disrupts mitochondrial dynamic balance through oxidative stress, induces excessive mitophagy and apoptosis, and ultimately leads to myocardial fibrosis. In the brain, Triphenyl phosphate activates the NF-κB inflammatory pathway by disrupting the gut microbiota, alters tryptophan metabolism and elevates neurotoxins, thereby inducing anxiety- and depression-like behaviors. In the skeletal and reproductive systems, Triphenyl phosphate inhibits osteoblast differentiation and induces germ cell apoptosis by suppressing the MAPK/ERK pathway and activating the JNK signal, respectively. In adipose and placental tissues, Triphenyl phosphate promotes lipid accumulation by activating the PI3K/AKT-PPARγ axis, and disrupts placental metabolism via the MAOA/ROS/NF-κB cascade, impairing neurodevelopment of offspring.
