Phospholipase A 2 and Phospholipase C Activities of Platelets DIFFERENTIAL
Deoxycholate treatment of horse platelets previously labeled in their phospholipids with [“Clarachidonate produces selective conversion of [“Clphosphatidylinositol (PI) to [‘4C]1,2-diacylglycerol. This phospholipase C activity, which has a pH optimum of 7.5, is specific for phosphatidylinositol since other phospholipids or neutral lipids are not affected. Although exogenous Ca2+ is not required...
متن کاملSynthesis and secretion of phospholipase C by oral spirochetes.
Four strains of oral treponemes and Treponema phagedenis Reiter synthesize and secrete phospholipase C (PLC), which was detected by the hydrolysis of p-nitrophenylphosphorylcholine. PLC was detected in gingival crevicular fluid from diseased but not from healthy sulci. The initiation and progression of periodontal lesions may begin with the hydrolysis of membrane phospholipids by PLC.
متن کاملPhysiological and pathophysiological roles for phospholipase D.
Individual members of the mammalian phospholipase D (PLD) superfamily undertake roles that extend from generating the second messenger signaling lipid, phosphatidic acid, through hydrolysis of the membrane phospholipid, phosphatidylcholine, to functioning as an endonuclease to generate small RNAs and facilitating membrane vesicle trafficking through seemingly nonenzymatic mechanisms. With recen...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولBrain ischemia decreases phosphatidylcholine-phospholipase D but not phosphatidylinositol-phospholipase C in rats.
BACKGROUND AND PURPOSE Phosphatidylcholine (PC)-phospholipase D (PLD) is an important intracellular signaling pathway in response to a variety of agonists, but little is known about the effects of brain ischemia on the PC-PLD system. We thus have examined the effects of global cerebral ischemia on PLD in rats. METHODS We have examined the effects of global ischemia (decapitation or four-vesse...
