Lipid peroxidation is essential for phospholipase C activity and the inositol-trisphosphate-related Ca²⁺ signal.
Reactive oxygen species (ROS) are produced in enzymatic and non-enzymatic reactions and have important roles in cell signalling but also detrimental effects. ROS-induced damage has been implicated in a number of neurological diseases; however, antioxidant therapies targeting brain diseases have been unsuccessful. Such failure might be related to inhibition of ROS-induced signalling in the brain...
متن کاملrole of cultural iran in promotion of multilaieralism in central asia and caucasus
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
15 صفحه اولPhospholipase C in Living Cells
We have further tested the hypothesis that receptor-mediated modulation of KCNQ channels involves depletion of phosphatidylinositol 4,5-bisphosphate (PIP2) by phosphoinositide-specific phospholipase C (PLC). We used four parallel assays to characterize the agonist-induced PLC response of cells (tsA or CHO cells) expressing M1 muscarinic receptors: translocation of two fluorescent probes for mem...
متن کاملStructure of the high affinity complex of inositol trisphosphate with a phospholipase C pleckstrin homology domain
The X-ray crystal structure of the high affinity complex between the pleckstrin homology (PH) domain from rat phospholipase C-delta 1 (PLC-delta 1) and inositol-(1,4,5)-trisphosphate (Ins(1,4,5)P3) has been refined to 1.9 A resolution. The domain fold is similar to others of known structure. Ins(1,4,5)P3 binds on the positively charged face of the electrostatically polarized domain, interacting...
متن کاملPhospholipase C Regulation of Phosphatidylinositol 3,4,5-trisphosphate-mediated Chemotaxis□V
Generation of a phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P3] gradient within the plasma membrane is important for cell polarization and chemotaxis in many eukaryotic cells. The gradient is produced by the combined activity of phosphatidylinositol 3-kinase (PI3K) to increase PI(3,4,5)P3 on the membrane nearest the polarizing signal and PI(3,4,5)P3 dephosphorylation by phosphatase and t...
