L-type amino acid transporters in two intestinal epithelial cell lines function as exchangers with neutral amino acids. (1/28)

The present study examined the functional characteristics of the inward [(14)C]-L-leucine transporter in two intestinal epithelial cell lines (human Caco-2 and rat IEC-6). The uptake of [(14)C]-L-leucine was largely promoted through an energy-dependent and sodium-insensitive transporter, although a minor component of [(14)C]-L-leucine uptake ( approximately 15%) required extracellular sodium. [(14)C] -L-leucine uptake was insensitive to N-(methylamino)-isobutyric acid, but competitively inhibited by 2-aminobicyclo(2,2,1)-heptane-2-carboxylic acid (BCH). Both L- and D-neutral amino acids, but not acidic and basic amino acids, markedly inhibited [(14)C]-L-leucine accumulation. The efflux of [(14)C]-L-leucine was markedly increased (P < 0.05) by L-leucine and BCH, but not by L-arginine. In IEC-6 cells, but not in Caco-2 cells, the uptake of [(14)C]-L-leucine at acidic pH (5.0 and 5.4) was greater (P < 0.05) than at pH 7.4. In conclusion, it is likely that system B(0) might be responsible for the sodium-dependent uptake of L-leucine in Caco-2 and IEC-6 cells, whereas sodium-independent uptake of L-leucine may include system LAT1, whose activation results in transstimulation of L-leucine outward transfer.  (+info)

Functional and molecular characteristics of system L in human breast cancer cells. (2/28)

The functional and molecular properties of system L in human mammary cancer cells (MDA-MB-231 and MCF-7) have been examined. All transport experiments were conducted under Na(+)-free conditions. alpha-Aminoisobutyric acid (AIB) uptake by MDA-MB-231 and MCF-7 cells was almost abolished by BCH (2-amino-2-norbornane-carboxylic acid). AIB uptake by MDA-MB-231 cells was also inhibited by L-alanine (83.6%), L-lysine (75.6%) but not by L-proline. Similarly, L-lysine and L-alanine, respectively, reduced AIB influx into MCF-7 cells by 45.3% and 63.7%. The K(m) of AIB uptake into MDA-MB-231 and MCF-7 cells was, respectively, 1.6 and 8.8 mM, whereas the V(max) was, respectively, 9.7 and 110.0 nmol/mg protein/10 min. AIB efflux from MDA-MB-231 and MCF-7 cells was trans-stimulated by BCH, L-glutamine, L-alanine, L-leucine, L-lysine and AIB (all at 2 mM). In contrast, L-glutamate, L-proline, L-arginine and MeAIB had no effect. The interaction between L-lysine and AIB efflux was one of low affinity. The fractional release of AIB from MDA-MB-231 cells was trans-accelerated by D-leucine and D-tryptophan but not by D-alanine. MDA-MB-231 and MCF-7 cells expressed LAT1 and CD98 mRNA. MCF-7 cells also expressed LAT2 mRNA. The results suggest that AIB transport in mammary cancer cells under Na(+)-free conditions is predominantly via system L which acts as an exchange mechanism. The differences in the kinetics of AIB transport between MDA-MB-231 and MCF-7 cells may be due to the differential expression of LAT2.  (+info)

Basolateral LAT-2 has a major role in the transepithelial flux of L-cystine in the renal proximal tubule cell line OK. (3/28)

During renal reabsorption, the amino acid transporters b(o,+) and y(+)L have a major role in the apical uptake of cystine and dibasic amino acids and in the basolateral efflux of dibasic amino acids, respectively. In contrast, the transporters responsible for the basolateral efflux of the apically transported cystine are unknown. This study shows the expression of system L and y(+)L transport activities in the basolateral domain of the proximal tubule-derived cell line OK and the cloning of the corresponding LAT-2 and y(+)LAT-1 cDNAs. Stable transfection with a LAT-2 antisense sequence demonstrated the specific role of LAT-2 in the basolateral system L amino acid exchange activity in OK cells. This partial reduction of LAT-2 expression decreased apical-to-basolateral trans-epithelial flux of cystine and resulted in a twofold to threefold increase in the intracellular content of cysteine. In contrast, the content of serine, threonine, and alanine showed a tendency to decrease, whereas other LAT-2 substrates were not affected. This demonstrates that LAT-2 plays a major specific role in the net basolateral efflux of cysteine and points to LAT-2 as a candidate gene to modulate cystine reabsorption.  (+info)

Functional properties of multispecific amino acid transporters and their implications to transporter-mediated toxicity. (4/28)

The absorption, distribution and excretion of most of xenobiotics, drugs, environmental toxins and their metabolites are mediated by membrane transporters. Recent advances in the transporter molecular biology have made it possible to investigate the mechanisms of transport of those exogenous compounds and their transporter-mediated toxicity at the molecular level. Exogenous compounds including drugs and toxic substances occurring in the environment pass through the transporters with broad substrate selectivity, namely "multispecific" transporters, taking advantage of the multispecific nature to exert their toxic effects. The remarkable examples of such transporter-mediated toxicity are 1-methyl-4-phenyl-2,3-dihydropyridinium (MPP+)-neurotoxicity mediated by dopamine transporters, cephaloridine-nephrotoxicity mediated by organic anion transporters and methylmercury-toxicity mediated by system L amino acid transporters. The molecular identification of system L transporter LAT1 (L-type amino acid transporter 1) has lead to the understanding of the mechanisms of their multispecific substrate recognition and revealed their localization at the blood-brain barrier and placental barrier. LAT1 relies on the hydrophobic interaction between substrate amino acid side chains and the substrate binding site, so that many variations are possible for the substrate amino acid side chains, which is the basis of the broad substrate selectivity. System L transporters, thus, function as a path for the membrane permeation of drugs and toxic compounds occurring in the environment with amino acid-related structures. Beside methylmercury-cysteine conjugate, amino acid-related neurotoxins such as beta-N-methylamino-L-alanine, S-(1,2-dichlorovinyl)-L-cysteine and 3-hydroxykynurenine are proposed to pass through system L transporters to exert their toxicity. Because the presence of such transporters is crucial for the manifestation of the organ toxicity, the inhibition of the transporters would be expected to be beneficial to prevent the disorders caused by the transporter-mediated toxicity.  (+info)

Identification of a novel system L amino acid transporter structurally distinct from heterodimeric amino acid transporters. (5/28)

A cDNA that encodes a novel Na+-independent neutral amino acid transporter was isolated from FLC4 human hepatocarcinoma cells by expression cloning. When expressed in Xenopus oocytes, the encoded protein designated LAT3 (L-type amino acid transporter 3) transported neutral amino acids such as l-leucine, l-isoleucine, l-valine, and l-phenylalanine. The LAT3-mediated transport was Na+-independent and inhibited by 2-aminobicyclo[2.2.1]heptane-2-carboxylic acid, consistent with the properties of system L. Distinct from already known system L transporters LAT1 and LAT2, which form heterodimeric complex with 4F2 heavy chain, LAT3 was functional by itself in Xenopus oocytes. The deduced amino acid sequence of LAT3 was identical to the gene product of POV1 reported as a prostate cancer-up-regulated gene whose function was not determined, whereas it did not exhibit significant similarity to already identified transporters. The Eadie-Hofstee plots of LAT3-mediated transport were curvilinear, whereas the low affinity component is predominant at physiological plasma amino acid concentration. In addition to amino acid substrates, LAT3 recognized amino acid alcohols. The transport of l-leucine was electroneutral and mediated by a facilitated diffusion. In contrast, l-leucinol, l-valinol, and l-phenylalaninol, which have a net positive charge induced inward currents under voltage clamp, suggesting these compounds are transported by LAT3. LAT3-mediated transport was inhibited by the pretreatment with N-ethylmaleimide, consistent with the property of system L2 originally characterized in hepatocyte primary culture. Based on the substrate selectivity, affinity, and N-ethylmaleimide sensitivity, LAT3 is proposed to be a transporter subserving system L2. LAT3 should denote a new family of organic solute transporters.  (+info)

Platelet-derived growth factor stimulates LAT1 gene expression in vascular smooth muscle: role in cell growth. (6/28)

Platelet-derived growth factor (PDGF) contributes to vascular disease by stimulating the growth of vascular smooth muscle cells (SMCs). Since amino acids are required for cell growth, the present study examined the effect of PDGF on system L amino acid transport, which is the predominant cellular pathway for the uptake of essential amino acids. System L amino acid transport was monitored by measuring the uptake of L-leucine. Treatment of SMCs with PDGF stimulated L-leucine transport in a concentration- and time-dependent manner, and this was associated with a selective increase in LAT1 mRNA and protein. PDGF failed to induce the expression of the other system L transport proteins, LAT2 and the heavy chain of the 4F2 cell surface antigen. The induction of LAT1 by PDGF was dependent on de novo RNA and protein synthesis and on mTOR activity. Serum, thrombin, and angiotensin II likewise stimulated L-leucine transport by inducing LAT1 expression. Inhibition of system L amino acid transport by the model substrate 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid blocked growth factor-mediated SMC proliferation and induced SMC apoptosis, whereas it had no effect on quiescent cells. These results demonstrate that growth factors stimulate system L amino acid transport by inducing LAT1 gene expression and that system L amino acid transport is essential for SMC proliferation and survival. The capacity of vascular mitogens to induce LAT1 expression may represent a basic mechanism by which tho acid transport * apoptosis  (+info)

Identification of LAT4, a novel amino acid transporter with system L activity. (7/28)

System L amino acid transporters mediate the movement of bulky neutral amino acids across cell membranes. Until now three proteins that induce system L activity have been identified: LAT1, LAT2, and LAT3. The former two proteins belong to the solute carrier family 7 (SLC7), whereas the latter belongs to SLC43. In the present study we present a new cDNA, designated LAT4, which also mediates system L activity when expressed in Xenopus laevis oocytes. Human LAT4 exhibits 57% identity to human LAT3. Like LAT3, the amino acid transport activity induced by LAT4 is sodium-, chloride- and pH-independent, is not trans-stimulated, and shows two kinetic components. The low affinity component of LAT4 induced activity is sensitive to the sulfhydryl-specific reagent N-ethylmaleimide but not that with high affinity. Mutation in LAT4 of the SLC43 conserved serine 297 to alanine abolishes sensitivity to N-ethylmaleimide. LAT4 activity is detected at the basolateral membrane of PCT kidney cells. In situ hybridization experiments show that LAT4 mRNA is restricted to the epithelial cells of the distal tubule and the collecting duct in the kidney. In the intestine, LAT4 is mainly present in the cells of the crypt.  (+info)

Homocysteine transport by human aortic endothelial cells: identification and properties of import systems. (8/28)

Hyperhomocysteinemia is an independent risk factor for cardiovascular disease. Transport of L-homocysteine into and out of the human vascular endothelium is poorly understood. We hypothesized that cultured human aortic endothelial cells (HAEC) would import L-homocysteine on one or more of the L-cysteine transport systems. Inhibitors of the transporters were used to characterize the uptake of [35S]L-homocysteine, [35S]L-homocystine, and [35S]L-cysteine. We found that L-homocysteine uptake is mediated by the sodium-dependent cysteine transport systems X(AG), ASC, and A, and the sodium-independent transport system L. Thus, HAEC utilize multiple cysteine transporters (X(AG) > or = L > ASC > A) to import L-homocysteine. Kinetic analysis supported the uptake results. Michaelis-Menten constants (Km) for the four systems yielded values of 19.0, 27.1, 112, and 1000 microM for systems L, X(AG), ASC, and A, respectively. The binding and uptake of [35S]L-homocystine, the disulfide homodimer of L-homocysteine, was mediated by systems X(AG), L, and ASC but not by system A. In contrast to [35S]L-homocysteine, system x(c) was active for [35S]L-homocystine uptake. A similar pattern was observed for [35S]L-cysteine. Thus, L-homocysteine and L-homocystine found in hyperhomocysteinemic subjects can gain entry into the vascular endothelium by way of multiple L-cysteine transporters.  (+info)

Nuclear Neuroimaging is becoming an important diagnostic tool with increasing impact in neurological and neuro-oncological practice. An emerging use of brain FDG-PET is the early recognition of a potentially treatable cause of rapid progressive dementia. This is the case of Autoimmune Limbic Encephalitis, where brain FDG-PET findings may appear even before characteristic brain MRI hyperintensities. On the other hand, PET is a well-established method in systemic oncology, and is being increasingly used to supplement MRI in the clinical management of brain tumors.

Pfeiffer R, Rossier G, Spindler B, Meier C, Kuhn L, Verrey F. Amino acid transport of y+L-type by heterodimers of 4F2hc/CD98 and members ofthe glycoprotein-associated amino acid transporter family.EMBO J. 1999 Jan 4;18(1):49-57. PMID: 9878049 [PubMed - indexed for MEDLINE]. Amino acid transport across cellular membranes is mediated by multiple transporters with overlapping specificities. We recently have identified the vertebrate proteins which mediate Na+-independent exchange of large neutral amino acids corresponding to transport system L. This transporter consists of a novel amino acid permease-related protein (LAT1 or AmAT-L-lc) which for surface expression and function requires formation of disulfide-linked heterodimers with the glycosylated heavy chain of the h4F2/CD98 surface antigen. We show that h4F2hc also associates with other mammalian light chains, e.g. y+LAT1 from mouse and human which are approximately 48% identical with LAT1 and thus belong to the same family of ...
A year or so ago I was aware that Royal Canin was using feathers in their pet food, to be honest at the time I thought it was an act of desperate cost saving, however it is a whole lot more clever than that!. So a little understanding of immune responses is essential here, basically the body is set up to detect and destroy evil foreign proteins(invaders). Sometimes however it goes wrong and recognises good (or normal) proteins as evil too. In food this causes Adverse Food Reactions, Atopic Dermatitis and so on. Now the immune response is also linked to the size of these proteins - the protein size is measured in Daltons which is the measurement for mass on an molecular scale - and the bigger the protein the bigger the response. This can be partly due to it being easier to see by the immune system.. The goal of Royal Canin was to produce a food with protein molecules that were less than 1kDa (1000 Daltons) in size to prevent the immune reaction. Now part of the Royal Canin philosophy is for ...

The purpose of this study was to examine the effect of 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH), an inhibitor of L-type amino acid transporters, on the cell growth suppression in KB human oral cancer cells and to study the roles of cell cycle regulatory factors in the BCH-induced growth inhibition. The effect of BCH on cell growth suppression and the influence of BCH to cell cycle regulatory factors in KB cell growth inhibition were examined using cell cycle analysis, immunoblotting and immunoprecipitation. The BCH treatment induced cell cycle arrest at G1 phase in KB cells. The expression of cyclin D3 was remarkably decreased by BCH treatment. The BCH inhibited the expression of cyclin-dependent protein kinase 6 (CDK6) in a time-dependent manner. In addition, the expression of CDK inhibitor p27 was increased by BCH treatment in KB cells, but not CDK inhibitors p21 and p15. These results suggest that, in KB cells, the inhibition of LAT1 by BCH causes cell cycle arrest at Cl phase ...

The mechanism of the observed decrease in the plasma concentration of several amino acids in the presence of high levels of Leu has remained unexplained. In the present study a decrease in the plasma concentration of Ile, Val, Phe, Tyr, Met, Ala, Pro and Gly was observed after the intraperitoneal injection of Leu to weanling rats. Decreases in net intracellular concentrations in muscle accompanied the decrease in plasma of all of these amino acids except Pro and Gly. An increase in the distribution ratio muscle/plasma was observed exclusively for Gly after administration of Leu or of a non-insulinogenic transport system L analogue. Diazoxide suppressed the Leu-induced decreases in plasma and muscle intracellular concentrations of Ile and Val as well as of Pro in plasma. An increase in the distribution ratio liver/plasma was observed for Pro and Gly in the absence but not in the presence of diazoxide. All the above changes were statistically significant. Hence insulin probably mediates Leu ...

Twenty-five hormone-naïve patients with histologically confirmed PCa underwent PET/CT before prostatectomy. Dynamic imaging was performed immediately after injection of 368 ± 10 MBq of 18F-fluciclovine and the uptake in PCa was expressed as SUVmax at six sequential 4-min time frames and as tracer distribution volume (VT) using Logan plots over 0-24 min. The expression of ASCT2 and LAT1 was studied with immunohistochemistry (IHC) on a tissue microarray (TMA) containing three cores per carcinoma lesion. The TMA slides were scored independently by two trained readers based on visual intensity of ASCT2/LAT1 expression on a four-tiered scale.

Abstract:. Peptides and proteins are large biomolecules composed of long chains of L -amino acids and plays key functions in the living organisms. A variety of techniques are used to characterize these biomolecules and, among the techniques used, high performance liquid chromatography (HPLC) has been extensively employed both for the preparative as well as the analytical characterization of peptides and proteins. Various HPLC techniques developed for the separation of proteins rely on the differences in the adsorption characteristics, surface charge, ligand specificity, and molecular size of protein molecules. Advancements made in these HPLC techniques have contributed immensely to the development of peptides and proteins based pharmaceuticals. Present article summarizes the principle, methods, and applications of the most common HPLC techniques used in the field of peptides and proteins.. ...
Neurotransmitters associated with pediatric neurotransmitter diseases include the catecholamines, serotonin, and the inhibitory neurotransmitter gamma-aminobuytric (GABA).. The pathways leading to the metabolism (production), synthesis (building up of), and catabolism (break down) of neurotransmitters are extremely complicated systems. The following is the pathways for the dopamine neurotransmitters pathway.. When there is a disruption within the neurotransmitter system, it can cause abnormalities with many of the brains essential functions. In pediatric neurotransmitter diseases children are born with genetic defects that affect the neurotransmitter pathways and the use of the related neurotransmitter. The specific pediatric neurotransmitter disease is determined by where the defect in the pathway occurs. For example in Aromatic L Amino Acid Decarboxylase (AADC) Deficiency the AADC enzyme is affected in the dopamine pathway and children cannnot effectively utilize the neurotransmitter ...
It should be noted that the functionally defined L-type amino acid transport activities as described in this and many other studies may result from a mixture of functionally similar amino acid transporters that share common features such as Na+ dependence, BCH sensitivity, and neutral amino acid substrate preference. To date, at least four members of this family, LAT1, LAT2, LAT3, and LAT4, have been cloned (Bodoy et al., 2005). LAT1 and LAT2 are heterodimeric transporters that require coexpression of both LAT and 4F2hc for function and exhibit trans-stimulation (Verrey, 2003). In contrast, LAT3 and LAT4 are structurally distinct from LAT1 and LAT2 and are functional independent of 4F2hc (Babu et al., 2003; Bodoy et al., 2005). It has been shown that different LAT subtypes exhibit distinct expression profiles across tissues and species (Verrey, 2003; Bodoy et al., 2005). Moreover, different LAT subtypes show differences in substrate specificity, transport kinetics, and other properties such as ...

Several studies have shown that the cRNA of human, rabbit, or rat rBAT induces in Xenopus oocytes sodium-independent, high affinity uptake of L-cystine via a system b0,(+)-like amino acid exchanger. We have shown that mutations in rBAT cause type I cystinuria (Calonge, M. J., Gasparini, P., Chillarón, J., Chillón, M., Gallucci, M., Rousaud, F., Zelante, L., Testar, X., Dallapiccola, B., Di Silverio, F., Barceló, P., Estivill, X., Zorzano, A., Nunes, V., and Palacín, M. (1994) Nat. Genet. 6, 420-425; Calonge, M.

U. S. A. 92, 9667-9671). Apart from oocytes, no other expression system has been used for transfection of functional rBAT activity. Furthermore, the b0,(+)-like transport activity has not been clearly described in the kidney or intestine. Here, we report that a proximal tubular-like cell ...
The transport of S-cysteine conjugates was studied in the kidney cell line, LLC-PK1, using the nephrotoxin, S-(1,2-dichlorovinyl)-L-cysteine (L-DCVC), as the model compound. The saturable uptake of this conjugate did not require sodium and was selectively inhibited by the amino acid transport system L-specific substrate, 2-amino-2-norbornane carboxylic acid, as well as a variety of other S-cysteine conjugates and neutral amino acids with large, nonpolar side chains. Kinetic studies suggested the existence of both low and high affinity transport systems with Km values that differed by 25-fold. Although these uptake systems showed no discernible differences in substrate specificity, the low affinity transport was more sensitive to trans-stimulation. L-DCVC uptake in subconfluent cultures was about 3-fold that of confluent cells, suggesting either adaptive regulation to cell growth or polarization of transport to the basolateral membrane. L-DCVC toxicity in LLC-PK1 cells was inhibited in the ...
Description: This purpose of this project is to build a prototype instrument that will, running unattended, detect, identify, and quantify BW agents. In order to accomplish this, we have chosen to start with the world� s leading, proven, assays for pathogens: surface-molecular recognition assays, such as antibody-based assays, implemented on a high-performance, identification (ID)-capable flow cytometer, and the polymerase chain reaction (PCR) for nucleic-acid based assays. With these assays, we must integrate the capability to: l collect samples from aerosols, water, or surfaces; l perform sample preparation prior to the assays; l incubate the prepared samples, if necessary, for a period of time; l transport the prepared, incubated samples to the assays; l perform the assays; l interpret and report the results of the assays. Issues such as reliability, sensitivity and accuracy, quantity of consumables, maintenance schedule, etc. must be addressed satisfactorily to the end user. The highest ...

This is the first study to assess the transport of neutral amino acids in both polarized plasma membranes of the placental transporting epithelium isolated from pregnancies complicated by GDM or type 1 diabetes with and without accelerated fetal growth as well as from pregnancies associated with fetal overgrowth despite apparently normal glucose metabolism. The transport of amino acids across MVMs is a secondary active process and represents the rate-limiting step in transplacental transfer of amino acids (36). System A is a Na+-dependent transporter mediating the uptake of neutral amino acids such as alanine, serine, and glutamine. In the current article, we demonstrate that amino acid transport mediated by system A is markedly increased in the syncytiotrophoblast MVM in association with diabetes during pregnancy. We suggest that these changes result in an increased uptake of neutral amino acids across MVM into the syncytiotrophoblast cytoplasm, which may increase the delivery of amino acids to ...
An interactive computer-simulation of experiments which may be performed on one of the classical in vitro techniques used to study intestinal absorption: the isolated, everted intestinal sac of the rat. The program simulates experiments designed to demonstrate the important characteristics of the transport of two important nutrients - hexoses and amino acids - in the small intestine. Introduction and Methods use a combination of text and high-resolution graphics to explain the everted sac preparation, the process of carrier-mediated transport of these nutrients and the methods used to measure it (using radiolabelled galactose, glycine and methionine and a scintillation counting technique). The Experiments section allows users to: 1. Measure the transport of these nutrients; 2. Demonstrate the Na+ dependence of the transport process; 3. Investigate the mutual interaction of the hexose and amino acid transport systems by performing a series of experiments (including a kinetic analysis and ...
