Effect of sodium vanadate
Platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine, AGEPC) and sodium vanadate (a phosphotyrosine phosphatase inhibitor) induced a timeand concentration-dependent increase in phosphotyrosine in several proteins and stimulated prostaglandin (PG) E2 production in cultured rat Kupffer cells. In addition, vanadate induced a decrease in the surface expression of AGEPC recepto...
متن کاملThe insulin-like effect of sodium vanadate
Sodium vanadate has several insulin-like effects. To determine whether vanadate acts via the insulin receptor, I investigated the effect of vanadate on glucose transport (2-deoxyglucose uptake) in adipocytes that had been treated to decrease the number of insulin receptors. (1) Trypsin (100 ,tg/ml) caused > 95% loss of 1251-insulin binding and rendered glucose transport resistant to both insuli...
متن کاملGrowth and Characterization of Vanadate Laser Crystals
Based on the invention and widely application of the Czochralski pulling method, vanadate crystals have been grown and commercialized in recent decades. In this paper, the growth and characterization of a series of neodymium doped vanadate crystals have been reviewed, including Nd:YVO4, Nd:GdVO4, and Nd:LuVO4. The excellent thermal-mechanical and laser property make them to be used in many resp...
متن کاملMechanism of inhibition of glycolysis by vanadate.
Vanadate is known to inhibit several phosphatases including Na+, K+-ATPase, alkaline phosphatase, and glyceraldehyde-3-P dehydrogenase. Inhibition presumably results because vanadium adopts a stable structure which resembles the transition state of phosphate during the reactions involving these enzymes. We performed experiments to further examine the effects of vanadate (VO3-4) on erythrocyte (...
متن کاملVanadate and aqueous humor dynamics. Proctor Lecture.
Topical administration of 0.5% vanadate lowers intraocular pressure in monkey and rabbit eyes. This appears to be a consequence of a reduction in the rate of aqueous humor secretion, probably resulting from the inhibition of ciliary epithelium membrane. NaK ATPase. The ubiquitous vanadate and its interactions with catecholamines and ascorbate may play a role in regulating the sodium pump of the...
