Oxidant-Mediated Activation of Phospholipases C and Dinding of hormones, neurotransmitters, growth factors, cytokines, and a variety of agonists to specific receptors results in the activation of effector enzymes, which catalyze the generation of second messengers. For example, activation of adenylate cyclase results in hydrolysis and conversion of AT

Peroxide Tone in Eicosanoid Signalingning whether those peroxides are intermediates without which the processes could not occur or are simply extraneous waste products. The peroxides and the processes are so intertwined that “oxidative stress” and signal transductions paradoxically seem at times to change their roles, as a cause produc

Protein Kinase C as a Sensor for Oxidative Stress in Tumor Promotion and ChemopreventionC represents a family of more than 11 isoenzymes, which are divided broadly into Ca.-dependent type (α,β,γ) and Ca.-independent type (δ,ε,ζ, etc.).. Differences in the subcellular localization as well as the expression of these isoenzymes in various cell types, enable PKC isoenzyme system to respond

Modulation by Oxidants and Antioxidants of Signal Transduction and Smooth Muscle Cell Proliferationration.. Smooth muscle cell growth is regulated by specific factors released from blood cells,. by the vessel wall cells. and by natural compounds, such as tocopherols. Active oxygen species (i.e., O., H.O., and OH) may act as vascular smooth muscle growth factors by inducing proto-oncogene expressi
