This study shows that 8- to 9-week type 1 diabetes induces an increase in mitochondrial FA β-oxidation without defects in the electron transport and identifies oxidation of FA rather than glycolysis-derived substrate (pyruvate) oxidation as the source of mitochondrial ROS in diabetic tubules. Because more than 90% of kidney cortex consists of proximal tubules, our results can be attributed to proximal tubule mitochondria. These changes in mitochondria coexist with renal structural and functional modifications consistent with the early stage of DN (35,36).. Diabetic cortical tubule mitochondria reach maximal respiratory rates with glutamate when oxidation is coupled with and depends on phosphorylation of ADP, and do not further increase when the control of oxidation by phosphorylation is eliminated by the uncoupler. These data show that the control site of oxidative phosphorylation is located at the level of glutamate oxidation to form NADH or electron transport rather than at the level of the ...
Normal pregnancy is associated with systemic and intrarenal vasodilatation resulting in an increased glomerular filtration rate. This adaptive response occurs in spite of elevated circulating levels of angiotensin II (Ang II). In the present study, we evaluated the potential mechanisms responsible for this adaptation. The reactivity of the mesangial cells (MCs) cultured from 14-day-pregnant rats to Ang II was measured through changes in the intracellular calcium concentration ([Cai]). The expression levels of inducible nitric oxide synthase (iNOS), the Ang II-induced vasodilatation receptor AT2, and the relaxin (LGR7) receptor were evaluated in cultured MCs and in the aorta, renal artery and kidney cortex by real time-PCR. The intrarenal distribution of LGR7 was further analyzed by immunohistochemistry. The MCs displayed a relative insensitivity to Ang II, which was paralleled by an impressive increase in the expression level of iNOS, AT2 and LGR7. These results suggest that the MCs also adapt to the
The shared transport system for uptake of L-cystine and L-lysine was examined in isolated rat renal brush-border membrane vesicles for the ionic requirements for activation of the system. No requirement for sodium was seen for either cystine or lysine influx. However, the efflux of lysine from the vesicle was stimulated by Na+. Therefore, the transport system appears to be asymmetric in its requirement for sodium. Two different divalent cations were used in the membrane isolations which resulted in different responses of cystine uptake to the electrogenic movement of K+ out of the vesicle. Membranes prepared by Mg-aggregation showed no stimulation of cystine influx by the imposition of a transient interior negative potential while vesicles prepared by Ca-aggregation did respond to electrogenic stimulation by an outwardly directed K-diffusion potential in the presence of valinomycin. Lysine influx was stimulated by electrogenic potassium efflux in both Mg-prepared and Ca-prepared membranes. No difference
Heavy metal pollution can arise from many sources and damage many organisms. Exposure to the metal ions can leads to a reduction in cellular antioxidant enzyme activities and lowers cellular defense against oxidative stress. In this study we have tested effects of the some metal ions on the purified bovine kidney cortex glutathione reductase (GR). Cadmium (Cd2+), nickel (Ni2+), and zinc (Zn2+) showed inhibitory effect on the enzyme. The obtained IC50 values of Cd2+, Ni2+, and Zn2+ are 0.027, 0.8, and 1mM, respectively. Kinetic characterization of the inhibition is also investigated. Cd2+ inhibition is noncompetitive with respect to both oxidized glutathione (GSSG) (KiGSSG 0.060 +/- 0.005mM) and NADPH (KiNADPH 0.025 +/- 0.002mM). Ni2+ inhibition is noncompetitive with respect to GSSG (KiGSSG 0.329 +/- 0.016mM) and uncompetitive with respect to NADPH (KiNADPH 0.712 +/- 0.047mM). The effect of Zn2+ on GR activity is consistent with noncompetitive inhibition pattern when the varied substrate is the ...
The mechanism by which gentamicin augments the uptake of p-aminohippurate (PAH) by rat renal cortical slices was investigated. In all experiments, gentamicin was administered as gentamicin sulfate at 100 mg/kg b.wt. per day for 2 days; control rats were injected with saline. The effect of gentamicin on the metabolism of PAH to p-aminobenzoic acid (PABA), acetyl-PABA and acetyl-PAH was studied by high performance liquid chromatography. No metabolites of PAH were detected in renal slices of gentamicin-injected or control rats incubated in medium containing PAH. Efflux of 14C-PAH was measured after incubating renal cortical slices for 2 hours in medium containing 8 X 10(-5) M 14C-PAH. The efflux rate constant was 0.080 +/- 0.003/min in control slices and 0.059 +/- 0.003/min in gentamicin slices, P less than .001. No significant difference in the diffusible pool of PAH was found between the two groups which supports an argument against increased tissue-binding of PAH as the explanation for the ...
Copyright © 2018 by The American Society for Pharmacology and Experimental Therapeutics. Transporter expression, determined by quantitative proteomics, together with PBPK models is a promising approach for in vitro-to-in vivo extrapolation (IVIVE) of transporter-mediated drug clearance. OCT2-expressing HEK293 and MDCKII cells were used to predict in vivo renal secretory clearance (CLr,sec) of metformin. [14C]-Metformin uptake clearance in OCT2-expressing cells was determined and scaled to in vivo CLr,sec by using OCT2 expression in the cells versus the human kidney cortex. Through quantitative targeted proteomics, the total expression of OCT2 in HEK293, MDCKII cells, and human kidney cortex was 369.4 6 26.8, 19 6 1.1, and 7.6 6 3.8 pmol/mg cellular protein, respectively. The expression of OCT2 in the plasma membrane of HEK293 and MDCKII cells, measured using an optimized biotinylation method followed by quantitative proteomics, was 30.2% and 51.6%, respectively. After correcting for percent of ...
Possible involvement of reversible phosphorylation and dephosphorylation of myosin light chain (MLC) by myosin light chain kinase (MLCK) and protein phosphatases (PPases), respectively, in the Ca++-calmodulin-dependent inhibition of renin secretion was investigated with the use of putative MLCK inhibitor ML-7 [1-(5-iodonaphthalene-1-sulfonyl)-1H-hexahydro-1,4-diazepine] and PPase type1 (PPase-1) and type 2A (PPase-2A) inhibitor calyculin A. ML-7 (1 × 10−6 to 3 × 10−5 M) increased renin secretion in vitro from rat renal cortical slices under resting conditions in a concentration-dependent manner with maximal 2.5-fold stimulation. Furthermore, Ca++-induced inhibition of renin secretion in depolarizing K+-rich Krebs-Ringer bicarbonate not only was prevented completely but also reversed by ML-7 in a concentration-dependent and reversible manner. On the other hand, calyculin A (3 × 10−6 M) blocked both effects of ML-7 on stimulation and reversal of renin secretion independently of ...
Uptake of SO42− into brush-border membrane vesicles isolated from rat kindey cortex by a Ca2+-precipitation method was investigated by using a rapid-filtration technique. Uptake of SO42− by the vesicles was osmotically sensitive and represented transport into an intra-vesicular space. Transport of SO42− by brush-border membranes was stimulated in the presence of Na+, compared with the presence of K+ or other univalent cations. A typical overshoot phenomenon was observed in the presence of an NaCl gradient (100mm-Na+ outside/zero mm-Na+ inside). Radioactive-SO42− exchange was faster in the presence of Na+ than in the presence of K+. Addition of gramicidin-D, an ionophore for univalent cations, decreased the Na+-gradient-driven SO42− uptake. SO42− uptake was only saturable in the presence of Na+. Counter-transport of Na+-dependent SO42− transport was shown with MoO42− and S2O32−, but not with PO42−. Changing the electrical potential difference across the vesicle membrane by ...
The Weinbaum-Jiji equation can be applied to situations where: 1) the vascular anatomy is known; 2) the blood velocities are known; 3) the effective modeling volume includes many vessels; and 4) the vessel equilibration length is small compared to the actual length of the vessel. These criteria are satisfied in the situation where steady-state heated thermistors are placed in the kidney cortex. In this paper, the Weinbaum-Jiji bioheat equation is used to analyze the steady state response of four different sized self-heated thermistors in the canine kidney. This heat transfer model is developed based on actual physical measurements of the vasculature of the canine kidney cortex. In this model, parallel-structured interlobular arterioles and venules with a 60 μm diameter play the dominant role in the heat transfer due to blood flow. Continuous power is applied to the thermistor, and the instrument measures the resulting steady state temperature rise. If an accurate thermal model is available, ...

TY - JOUR. T1 - Expression of Na+-H+ exchanger isoforms NHE1 and NHE3 in kidney and blood cells of rabbit and rat. AU - Rutherford, P. A.. AU - Pizzonia, J. H.. AU - Biemesderfer, D.. AU - Abu-Alfa, A.. AU - Reilly, R.. AU - Aronson, P. S.. PY - 1997/11. Y1 - 1997/11. N2 - Increased peripheral blood cell Na-H exchange (NHE) and erythrocyte Na- Li countertransport activity have been reported in hypertension and diabetic nephropathy and correlated with increased activity of the renal brush border Na-H exchanger. A relationship between cation exchange activities of blood cells and renal brush border membranes might exist if both were mediated by the same NHE isoform. We generated isoform-specific antibodies to compare the expression of NHE1 and NHE3 in peripheral blood cell membranes and renal cortical membrane vesicles. An NHE1-specific monoclonal antibody reacted with a 199- to 110-kD protein in basolateral membrane fractions isolated from rabbit and rat kidney. NHE1 protein expression was also ...

We used a mathematical model of O(2) transport and the urine concentrating mechanism of the outer medulla of the rat kidney to study the effects of blood pH and medullary blood flow on O(2) availability and Na(+) reabsorption. The model predicts that in vivo paracellular Na(+) fluxes across medullary thick ascending limbs (mTALs) are small relative to transcellular Na(+) fluxes and that paracellular fluxes favor Na(+) reabsorption from the lumen along most of the mTAL segments. In addition, model results suggest that blood pH has a significant impact on O(2) transport and Na(+) reabsorption owing to the Bohr effect, according to which a lower pH reduces the binding affinity of hemoglobin for O(2). Thus our model predicts that the presumed greater acidity of blood in the interbundle regions, where mTALs are located, relative to that in the vascular bundles, facilitates the delivery of O(2) to support the high metabolic requirements of the mTALs and raises the concentrating capability of the outer ...

TY - JOUR. T1 - Selective removal of alkaline phosphatase from renal brush-border membrane and sodium-dependent brush-border membrane transport. AU - Yusufi, A. N.K.. AU - Low, M. G.. AU - Turner, S. T.. AU - Dousa, T. P.. N1 - Copyright: Copyright 2004 Elsevier B.V., All rights reserved.. PY - 1983. Y1 - 1983. N2 - Na+-gradient-dependent transport of phosphate (P(i), glucose, and proline was studied in renal brush-border membranes (BBM) from which alkaline phosphatase was released by treatment with phosphatidylinositol-specific phospholipase C. BBM were prepared from rabbit kidney cortex in the form of large brush-border membrane sheets (BBMS). Incubation of BBMS with bacterial phosphatidylinositol-specific phospholipase C resulted in selective release (up to 90%) of the alkaline phosphatase from BBM; in contrast, activities of leucine aminopeptidase, γ-glutamyltranspeptidase, and maltase were not affected. Polytron homogenization of BBMS leads to the formation of brush-border membrane ...
The intracellular sodium concentration [( Na+]i) of dog kidney cortical tubules was monitored by flame photometry and 23Na NMR using dysprosium tripolyphosphate as shift reagent. Upon addition of substrates cotransported with sodium, flame photometry showed an increase in [Na+]i while no change (glutamine, glucose) or even a decrease (lactate) in the Na+i NMR signal was observed. This discrepancy could not be explained by a lack of ATP prior to the addition of substrates or by a decrease of NMR visibility of Nai+ induced by binding of substrate to membrane transporters (and pump). We propose that a variation of the apparent visibility of Nai+ may occur, arising from either a compartmentation of Nai+ in dog cortical tubules or an inhomogeneous extracellular distribution of the shift reagent.
TY - CHAP. T1 - Actions of NAD+ on renal brush border transport of phosphate in vivo and in vitro. AU - Kempson, S. A.. AU - Turner, Stephen T. AU - Yusufi, A. N K. AU - Dousa, T. P.. PY - 1985. Y1 - 1985. N2 - Previous studies showed that an increase in NAD+ content in renal cortex in vivo was accompanied by specific inhibition of Na+-dependent inorganic phosphate (P(i)) transport across the renal brush border membrane (BBM). Further, in vitro addition of NAD+ to isolated renal BBM vesicles specifically inhibited Na+ gradient-dependent transport of P(i). The present study examined some aspects of the mechanism of this inhibition by NAD+ in vitro and in vivo. When NAD+ was increased in vivo by nicotinamide injection, the apparent V(max) was decreased, but the apparent K(m) was not different, indicating apparent noncompetitive inhibition. In the presence of 0.3 mM NAD+ added in vitro, the apparent K(m) for Na+-dependent P(i) transport by BBM vesicles was increased, whereas the apparent V(max) was ...
TY - JOUR. T1 - Differential uptake of isomeric 2-bromohydroquinone-glutathione conjugates into kidney slices. AU - Lau, Serrine. AU - McMenamin, Mary G.. AU - Monks, Terrence. PY - 1988/4/15. Y1 - 1988/4/15. N2 - 2-Bromo-(diglutathion-Syl)hydroquinone (2-Br-[diGSyl]HQ) is a more potent nephrotoxicant than any of three mono-substituted isomers. The reason for this differential toxicity is unknown. We now report that the rate of uptake of 2-Br-(diGSyl)HQ, 2-Br-3-(GSyl)HQ, 2-Br-5-(GSyl)-HQ and 2-Br-6(GSyl)HQ by kidney slices was 2.4, 1.2, 1.0 and 0.3 nmoles/mg/10 min, respectively. AT-125 (0.5 mM) inhibited γ-glutamyl transpeptidase (GGT) in intact and homogenized kidney slices by 47% and 92%, respectively and decreased the accumulation of the isomeric [35S]-conjugates by 49%, 21%, 25% and 30%, respectively. The data suggest that the accumulation of 2-Br-(GSyl)HQ conjugates into isolated kidney slices may in part be mediated by GGT and that the more extensive renal uptake of the di-substituted ...
Dysfunctional mitochondria are a primary pathological consequence of acute kidney injury (AKI). Mitochondrial homeostasis is disrupted up to 144 h after ischemia-reperfusion (I/R) induced-AKI in the renal cortical tissue of mice. Stimulation of mitochondrial biogenesis in renal cells after oxidant injury restores mitochondrial function. The primary goals of this project were to identify novel pharmacological compounds capable of inducing mitochondrial biogenesis in the renal proximal tubule and evaluate if this induction would promote the recovery of mitochondrial and/or renal function after in vivo AKI. The secondary goal was to employ our mitochondrial approach for drug discovery towards identifying a novel treatment for a different disease state, skeletal muscle atrophy. Stimulation of the G-protein couple receptor (GPCR) family in response to physiological stress results in the downstream activation of effectors, which upregulates the expression and activity of PGC-1α and subsequently ...

N2 - In this investigation, we have demonstrated that the renal brush-border membrane of Fischer 344 rats from the Japanese Charles River Inc. specifically lacks dipeptidyl peptidase IV (DPP IV) activity, whereas the renal brush-border membrane of Fischer 344 rats from three different sources within the United States possesses normal levels of DPP IV activity. Comparison of the brush-border proteins between Charles River (U. S. A.) Fischer 344 rats (DPP IV positive) and Japanese Charles River Fischer 344 rats (DPP IV negative) revealed that a protein band (Mr = 100,000), apparently identical with DPP IV, was absent in ...

N2 - This study examined the mechanism of release of endogenous acetylcholine (ACh) in rabbit renal cortex by applying a microdialysis technique. In anesthetized rabbits, a microdialysis probe was implanted into the renal cortex and perfused with Ringers solution containing high potassium concentration, high sodium concentration, a Na+/K+-ATPase inhibitor (ouabain), or an epithelial Na+ channel blocker (benzamil). Dialysate samples were collected at baseline and during exposure to each agent, and ACh concentrations in the samples were measured by high-performance liquid chromatography. High potassium had no ...
The transport properties of brush-border membrane vesicles isolated by a calcium-precipitation method from the renal cortex of normal and parathyrin (parathyroid hormone)-treated rats were studied by a rapid-filtration technique. Parathyrin elicited a dose-dependent decrease in the Na+-dependent phosphate uptake by the brush-border membrane vesicles, but the uptake of D-glucose, Na+ and mannitol was not affected. A maximum inhibition of 30% was observed after the application of 30 U.S.P. units intramuscularly 1 h before the animals were killed. Intravenous infusion of dibutyryl cyclic AMP (0.5-1.5 MG) also decreased the phosphate uptake by the brush-border vesicles. Both dibutyryl cyclic AMP and parathyrin were ineffective when added in vitro to brush-border membrane vesicles isolated from normal rats. These data suggest that parathyrin exerts its action on the phosphate reabsorption in the renal proximal tubule by affecting the Na+/phosphate co-transport system in the brush-border membrane. The ...
We have used the subtype-selective radioligands [3H]prazosin (an alpha 1-adrenergic antagonist) and [3H]yohimbine (an alpha 2-adrenergic antagonist) to examine alpha-adrenergic receptors in rat renal cortical membranes. Under the conditions used in this study, [3H]prazosin bound only to alpha 1-adrenergic receptors, whereas [3H]yohimbine bound only to alpha 2-adrenergic receptors; the two radioligands were completely selective and did not bind to a common site. The ratio of alpha 2- to alpha 1-adrenergic receptors was about 3:1. Guanyl nucleotides decreased the affinity of epinephrine at both receptor subtypes, but this effect was greater at the alpha 2-receptor and, according to computer analysis, occurred through different mechanisms at the two receptor subtypes. NaCl decreased the affinity of epinephrine at both alpha-receptor subtypes; this effect was more Na+-selective at alpha 2- than at alpha 1-receptors. Guanyl nucleotides and NaCl were additive in decreasing the affinity of epinephrine ...
TY - JOUR. T1 - Phenolsulphotransferase in human tissue. T2 - Radiochemical enzymatic assay and biochemical properties. AU - Anderson, Robert J.. AU - Weinshilboum, R. M.. PY - 1980/4/11. Y1 - 1980/4/11. N2 - Phenolsulphotransferase (EC 2.8.2.1) (PST) is an important catecholamine and drug metabolizing enzyme. Optimal conditions have been determined for the accurate measurement of PST activity in the human platelet, human renal cortex, and human jejunum with a radiochemical microassay. 3-Methoxy-4-hydroxyphenylglycol (MHPG) and 35S-3-phosphoadenosine-5-phosphosulfate (35S-PAPS) were the substrates for the reaction. The apparent Michaelis-Menten (Km) values for MHPG with platelet, renal cortex, and jejunum were 1.09, 0.46 and 1.16 mmol/l, respectively. Apparent Km values for PAPS in the same tissues were 0.14, 0.13 and 0.21 μmol/l. The pH optimum of the reaction in all three tissues was approximately 6.2-6.8 with three different buffer systems. The coefficients of variation for the assay of ...
BACKGROUNDOsteogenic protein-1/bone morphogenetic protein-7 (OP-1/BMP-7), a member of the transforming growth factor-beta superfamily, has been shown to prevent kidney damage from ischemia/reperfusion injury in rats. The molecular events involved in OP-1 action on kidney are not yet understood.METHODSIn this study, we evaluated the biodistribution of (125)I-labeled OP-1 in rat kidneys. Adult rats received a single intravenous injection of 250 microg (125)I-labeled OP-1 per kg body wt, a dose that was effective in protecting kidneys from ischemic injury. Tissue localization, in situ hybridization, and immunostaining with a specific receptor antibody were performed to identify OP-1 cellular targets. Also, isolated plasma membranes from kidney cortex and medulla regions were analyzed to identify and characterize receptor structural components that recognize OP-1.RESULTSAt 10 and 180 minutes following injection, the relative uptake of (125)I-labeled OP-1 was consistently higher in kidney cortex than ...
The main new findings of this study are that normal rats have a graded increase in the excretion of 8-Iso with salt intake. This is mirrored by MDA but not by PGE2. The increased oxidative stress during HS is accompanied by increased NADPH and NADH oxidase activity in the kidney cortex and increased expression of the mRNA in the kidney cortex for the NAD(P)H oxidase components gp91phox and p47phox and decreased expression of the mRNA for IC- and Mn-SOD.. O2·− interacts with arachidonate that is free or esterified into membrane phospholipids to yield isoprostanes. The steady-state excretion of 8-Iso has been used as an index of bodily oxidative stress (21). Comparing rats of HS with NS, the excretion of 8-Iso doubled, whereas urine flow increased fourfold. By contrast, comparing rats of LS with NS, the excretion of 8-Iso was reduced significantly without a change in urine flow. Changes in 8-Iso were paralleled by MDA, which is not a cyclooxygenase product and is another widely used marker of ...
The effects of guanosine 5-triphosphate (GTP) and GTP-gamma-S, known activators of GTP binding proteins, on proton transport were investigated in endosome-enriched vesicles (endosomes). Endosomes were prepared from rabbit renal cortex following the intravenous injection of FITC-dextran. The rate of intravesicular acidification was determined by measuring changes in fluorescence of FITC-dextran. Both GTP and GTP-gamma-S stimulated significantly the initial rate of proton transport. In contrast, GDP-beta-S, which does not activate GTP binding proteins, inhibited proton transport. The rank order of stimulation was GTP-gamma-S greater than GTP greater than control greater than GDP-beta-S. GTP-gamma-S stimulation of proton transport was also observed under conditions in which chloride entry was eliminated, i.e., 0 mM external chloride concentration in the presence of potassium/valinomycin voltage clamping. GTP-gamma-S did not affect proton leak in endosomes as determined by collapse of H+ ...
