A nucleoside-sensitive organic cation transporter in opossum kidney cells.
Renal secretion of organic cations and anions are pleiotropic, active processes in mammals. Some nucleosides such as deoxyadenosine (dAdo), 2-chlorodeoxyadenosine, and azidothymidine are secreted by human and rodent kidneys. Previous work (J. A. Nelson, J. F. Kuttesch, Jr., and B. H. Herbert. Biochemical Pharmacology 32: 2323-2327, 1983) indicated a role for the classic organic cation transport...
متن کاملCloning of a Na/Pi cotransporter from opossum kidney cells.
Opossum kidney (OK) cells have been extensively used to study cellular mechanisms of renal proximal tubular Na/P(i) cotransport. We have cloned a cDNA (NaPi-4) most likely encoding an apical Na/P(i) cotransporter from OK cells. The cloning strategy was based on homology to the recently cloned human renal (NaPi-3) Na/P(i) cotransporter (Magagnin, S., Werner, A., Markovich, D., Sorribas, V., Stan...
متن کاملα2C-Adrenoceptors modulate L-DOPA uptake in opossum kidney cells and in the mouse kidney.
Targeted deletion or selective pharmacological inhibition of α(2C)-adrenoceptors in mice results in increased brain tissue levels of dopamine and its precursor l-3,4-dihydroxyphenylalanine (l-DOPA), without significant changes in l-DOPA synthesis. l-DOPA uptake is considered the rate-limiting step in dopamine synthesis in the kidney. Since α(2C)-adrenoceptors may influence the transport of l-DO...
متن کاملPreparation of Microvilli from Rabbit Kidney
A simple method for the isolation of microvilli from kidney brush border is described. The method depends on the preferential aggregation of other subcellular structures by bivalent metal ions. MgCl2 is added to a homogenate of cortical tissue prepared from frozen rabbit kidneys. Aggregated material is removed by a low-speed centrifugation and the supematant centrifuged at 15000g to yield a pel...
متن کاملStatic and dynamic lengths of neutrophil microvilli.
Containing most of the L-selectin and P-selectin glycoprotein ligand-1 (PSGL-1) on their tips, microvilli are believed to promote the initial arrest of neutrophils on endothelium. At the rolling stage following arrest, the lifetimes of the involved molecular bonds depend on the pulling force imposed by the shear stress of blood flow. With two different methods, electron microscopy and micropipe...
