Inorganic Phosphate Homeostasis
to transport Pi according to the dietary Pi: TRPt was always higher, for a given [Pt]P1, in the animals fed low than in those fed higher Pi diets. This diet-induced modification also occurred in the absence of thyroparathyroid glands, in the presence of the same calcemia and urinary pH, and during marked extracellular volume expansion. A time-course study in rats TPTX both before and during the...
متن کاملInorganic phosphate homeostasis in sodium-dependent phosphate cotransporter Npt2b⁺/⁻ mice.
An inorganic phosphate (P(i))-restricted diet is important for patients with chronic kidney disease and patients on hemodialysis. Phosphate binders are essential for preventing hyperphosphatemia and ectopic calcification. The sodium-dependent P(i) (Na/P(i)) transport system is involved in intestinal P(i) absorption and is regulated by several factors. The type II sodium-dependent P(i) transport...
متن کاملCharacterization of inorganic phosphate transport in osteoclast-like cells.
Osteoclasts possess inorganic phosphate (Pi) transport systems to take up external Pi during bone resorption. In the present study, we characterized Pi transport in mouse osteoclast-like cells that were obtained by differentiation of macrophage RAW264.7 cells with receptor activator of NF-kappaB ligand (RANKL). In undifferentiated RAW264.7 cells, Pi transport into the cells was Na+ dependent, b...
متن کاملThe inhibition of mitochondrial dicarboxylate transport by inorganic phosphate, some phosphate esters and some phosphonate compounds.
1. P(i) competitively inhibited succinate oxidation by intact uncoupled mitochondria in the presence of sufficient N-ethylmaleimide to block the phosphate carrier, with a K(i) of 2.5mm. 2. Of a large number of phosphate esters and phosphonate compounds, phenyl phosphate and phenylphosphonate were found to inhibit competitively uncoupled succinate oxidation by intact but not broken mitochondria....
متن کاملActivation of a plant invertase by inorganic phosphate.
Activation by orthophosphate of a plant invertase from root nodules of Lupinus luteus L. has been demonstrated. The activation affects an increase in maximum velocity (V(max)) of the reaction. Activation was also achieved with a number of similar anions and it has been possible to infer a broad classification of anions capable of serving as activators. The possibility of orthophosphate activati...
