Salt loading induces redistribution of the plasmalemmal Na/K-ATPase in proximal tubule cells.
BACKGROUND We have reported that digitalis-like substances (cardiotonic steroids), including marinobufagenin (MBG), induce endocytosis of the plasmalemmal Na/K-ATPase in LLC-PK1 cells. The current report addresses the potential relevance of plasmalemmal Na/K-ATPase redistribution to in vivo salt handling. METHODS Male Sprague-Dawley rats were given 1 week of a high salt (4.0% NaCl) or normal ...
متن کاملDietary K regulates ROMK channels in connecting tubule and cortical collecting duct of rat kidney.
The activity of ROMK channels in rat kidney tubule cells was assessed as tertiapin-Q (TPNQ)-sensitive current under whole cell clamp conditions. With an external K(+) concentration of 5 mM and an internal K(+) concentration of 140 mM and the membrane potential clamped to 0 mV, TPNQ blocked outward currents in principal cells of the cortical collecting duct (CCD) outer medullary collecting duct ...
متن کاملExpression of the type IV collagenase system during mouse kidney development and tubule segmentation.
Type IV collagenases matrix metalloproteinase-2 (MMP2) and MMP9 and their related proteins, MT1-MMP, tissue inhibitor of metalloproteinases 1 (TIMP1), TIMP2, and TIMP3, are expressed during kidney morphogenesis and nephrogenesis, but the renal ontogeny of these proteins is only partially known, and their persistence in the adult remains controversial. Their expression was analyzed from early me...
متن کاملExpression of aquaporins in the renal connecting tubule.
The renal connecting tubule (CNT) is a distinct segment that occurs between the distal convoluted tubule (DCT) and the cortical collecting duct. On the basis of its characterization in rabbit it is widely believed that connecting tubule cells have a low permeability to water and do not respond to vasopressin. Here we utilize segment-specific markers and specific aquaporin antibodies to characte...
متن کاملStudy of Expression Type Iv Collagen During Mouse Kidney Ubulogenesis in Balb/C Mouse
Purpose: In this study specific antibody have been used for tracing type IV collagen basement membrane during renal tubules morphogenesis in mouse fetuses. Materials and Methods: 20 female Balb/C mice were selected randomly and were kept under normal condition, finding vaginal plug was assumed as day zero of pregnancy. 12 pregnant mice were scarified by cervical dislocation in one of gestationa...
