In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Antigens, CD81: Tetraspanin proteins that are involved in a variety of cellular functions including BASEMENT MEMBRANE assembly, and in the formation of a molecular complexes on the surface of LYMPHOCYTES.Protein Conformation: The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain.

Signaling by the activated receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.Calcium: A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.Multiple Myeloma: A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.Paraproteinemias: A group of related diseases characterized by an unbalanced or disproportionate proliferation of immunoglobulin-producing cells, usually from a single clone.

It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma.

At least 20 antigens have been identified which are encoded by the A locus of multiple alleles on chromosome 6. They serve as targets for T-cell cytolytic responses and are involved with acceptance or rejection of tissue/organ grafts.Immunoglobulin Constant Regions: The domains of the immunoglobulin molecules that are invariable in their amino acid sequence within any class or subclass of immunoglobulin. They confer biological as well as structural functions to immunoglobulins.

They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).Turkeys: Large woodland game BIRDS in the subfamily Meleagridinae, family Phasianidae, order GALLIFORMES.

It is now known that a variety of light chain subunits (ANTIGENS, CD98 LIGHT CHAINS) can dimerize with the heavy chain. Depending upon its light chain composition a diverse array of functions can be found for this protein. Functions include: type L amino acid transport, type y+L amino acid transport and regulation of cellular fusion.Blotting, Western: Identification of proteins or peptides that have been electrophoretically separated by blot transferring from the electrophoresis gel to strips of nitrocellulose paper, followed by labeling with antibody probes.Antigens, CD63: Ubiquitously-expressed tetraspanin proteins that are found in late ENDOSOMES and LYSOSOMES and have been implicated in intracellular transport of proteins.Immunization: Deliberate stimulation of the host's immune response.

Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).HLA-D Antigens: Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.Mollusca: A phylum of the kingdom Metazoa.

CD98-mediated links between amino acid transport and beta 1 integrin distribution in polarized columnar epithelia. (1/46)In non-polarized cells, CD98 has been shown to both influence beta(1) integrins and heterodimerize with LAT-2, which confers amino acid transport capability on the LAT-2/CD98 heterodimer. Since LAT-2 is most heavily expressed in intestine and CD98 associates with the beta(1) integrin splice form selectively found in such epithelia, we investigated the relationship and polarity of these proteins using the intestinal epithelial model Caco2-BBE. CD98 was found to selectively coimmunoprecipitate with both LAT-2 and beta(1) integrin, and, logically, all three proteins were polarized to the same (basolateral) domain. Furthermore, expression of CD98 in polarized epithelia lacking human CD98 (MDCK cells) disrupted beta(1) integrin surface distribution and cytoskeletal architecture, suggesting that CD98 can influence integrin function. Expression of a CD98 mutant lacking the specific residues conferring LAT-2 binding similarly affected cells, confirming that the latter effect was not due to LAT-2 sequestration. Use of CD98 truncation mutants suggest that a 10-amino acid domain located at the putative cytoplasmic tail/transmembrane domain interface was necessary and sufficient to induce the phenotype change. We conclude that the CD98/LAT-2 amino acid transporter is polarized to the same domain on which beta(1) integrin resides. CD98 appears to associate with beta(1) integrin and, in doing so, may influence its function as revealed by disruption of the outside-in signaling that confers cytoskeletal organization. Furthermore, such findings suggest a link between classic transport events and a critical element of barrier function: integrin-mediated influences on cytoskeletal organization. (+info)
Two-way arginine transport in human endothelial cells: TNF-alpha stimulation is restricted to system y(+). (2/46)Human umbilical vein endothelial cells transport arginine through two Na(+)-independent systems. System y(+)L is insensitive to N-ethylmaleimide (NEM), inhibited by L-leucine in the presence of Na(+), and referable to the expression of SLC7A6/y(+)LAT2, SLC7A7/y(+)LAT1, and SLC3A2/4F2hc. System y(+) is referable to the expression of SLC7A1/CAT1 and SLC7A2/CAT2B. Tumor necrosis factor-alpha (TNF-alpha) and bacterial lipopolysaccharide induce a transient stimulation of arginine influx and efflux through system y(+). Increased expression of SLC7A2/CAT2B is detectable from 3 h of treatment, while SLC7A1 expression is inhibited at later times of incubation. System y(+)L activity and expression remain unaltered. Nitric oxide synthase type 2 mRNA is not detected in the absence or presence of TNF-alpha, while the latter condition lowers nitric oxide synthase type 3 expression at the mRNA and the protein level. Nitrite accumulation is comparable in cytokine-treated and control cells up to 48 h of treatment. It is concluded that modulation of endothelial arginine transport by TNF-alpha or lipopolysaccharide occurs exclusively through changes in CAT2B and CAT1 expression and is dissociated from stimulation of nitric oxide production.

A study of L-leucine, L-phenylalanine and L-alanine transport in the perfused rat mammary gland: possible involvement of LAT1 and LAT2. (3/46)The transport of L-leucine, L-phenylalanine and L-alanine by the perfused lactating rat mammary gland has been examined using a rapid, paired-tracer dilution technique. The clearances of all three amino acids by the mammary gland consisted of a rising phase followed by a rapid fall-off, respectively, reflecting influx and efflux of the radiotracers. The peak clearance of L-leucine was inhibited by BCH (65%) and D-leucine (58%) but not by L-proline. The inhibition of L-leucine clearance by BCH and D-leucine was not additive. L-leucine inhibited the peak clearance of radiolabelled L-leucine by 78%. BCH also inhibited the peak clearance of L-phenylalanine (66%) and L-alanine (33%) by the perfused mammary gland. Lactating rat mammary tissue was found to express both LAT1 and LAT2 mRNA. The results suggest that system L is situated in the basolateral aspect of the lactating rat mammary epithelium and thus probably plays a central role in neutral amino acid uptake from blood. The finding that L-alanine uptake by the gland was inhibited by BCH suggests that LAT2 may make a significant contribution to neutral amino acid uptake by the mammary epithelium. (+info)
Transport of a neurotoxicant by molecular mimicry: the methylmercury-L-cysteine complex is a substrate for human L-type large neutral amino acid transporter (LAT) 1 and LAT2. (4/46)Methylmercury (MeHg) readily crosses cell membrane barriers to reach its target tissue, the brain. Although it is generally assumed that this rapid transport is due to simple diffusion, recent studies have demonstrated that MeHg is transported as a hydrophilic complex, and possibly as an L-cysteine complex on the ubiquitous L-type large neutral amino acid transporters (LATs). To test this hypothesis, studies were carried out in Xenopus laevis oocytes expressing two of the major L-type carriers in humans, LAT1-4F2 heavy chain (4F2hc) and LAT2-4F2hc. Oocytes expressing LAT1-4F2hc or LAT2-4F2hc demonstrated enhanced uptake of [(14)C]MeHg when administered as the L-cysteine or D,L-homocysteine complexes, but not when administered as the D-cysteine, N -acetyl-L-cysteine, penicillamine or GSH complexes. Kinetic analysis of transport indicated that the apparent affinities ( K (m)) of MeHg-L-cysteine uptake by LAT1 and LAT2 (98+/-8 and 64+/-8 microM respectively) were comparable with those for methionine (99+/-9 and 161+/-11 microM), whereas the V (max) values were higher for MeHg-L-cysteine, indicating that it may be a better substrate than the endogenous amino acid. Uptake and efflux of [(3)H]methionine and [(14)C]MeHg-L-cysteine were trans -stimulated by leucine and phenylalanine, but not by glutamate, indicating that MeHg-L-cysteine is both a cis - and trans -substrate. In addition, [(3)H]methionine efflux was trans -stimulated by leucine and phenylalanine even in the presence of an inwardly directed methionine gradient, demonstrating concentrative transport by both LAT1 and LAT2. The present results describe a major molecular mechanism by which MeHg is transported across cell membranes and indicate that metal complexes may form a novel class of substrates for amino acid carriers. These transport proteins may therefore participate in metal ion homoeostasis and toxicity. (+info)
Functional cooperation of epithelial heteromeric amino acid transporters expressed in madin-darby canine kidney cells. (5/46)The heteromeric amino acid transporters b(0,+)AT-rBAT (apical), y(+)LAT1-4F2hc, and possibly LAT2-4F2hc (basolateral) participate to the (re)absorption of cationic and neutral amino acids in the small intestine and kidney proximal tubule. We show now by immunofluorescence that their expression levels follow the same axial gradient along the kidney proximal tubule (S1>S2S3). We reconstituted their co-expression in MDCK cell epithelia and verified their polarized localization by immunofluorescence. Expression of b(0,+)AT-rBAT alone led to a net reabsorption of l-Arg (given together with l-Leu). Coexpression of basolateral y(+)LAT1-4F2hc increased l-Arg reabsorption and reversed l-Leu transport from (re)absorption to secretion. Similarly, l-cystine was (re)absorbed when b(0,+)AT-rBAT was expressed alone. This net transport was further increased by the coexpression of 4F2hc, due to the mobilization of LAT2 (exogenous and/or endogenous) to the basolateral membrane. In summary, apical b(0,+)AT-rBAT cooperates with y(+)LAT1-4F2hc or LAT2-4F2hc for the transepithelial reabsorption of cationic amino acids and cystine, respectively. The fact that the reabsorption of l-Arg led to the secretion of l-Leu demonstrates that the implicated heteromeric amino acid transporters function in epithelia as exchangers coupled in series and supports the notion that the parallel activity of unidirectional neutral amino acid transporters is required to drive net amino acid reabsorption.

Isoform selectivity of 3-125I-iodo-alpha-methyl-L-tyrosine membrane transport in human L-type amino acid transporters. (6/46)3-(123)I-Iodo-alpha-methyl-L-tyrosine ((123)I-IMT) has been developed for SPECT of amino acid transport imaging. We examined the isoform selectivity of (125)I-IMT transport of the 2 human L-type amino acid transporters, hLAT1 and hLAT2, with human 4F2hc-coexpressed Xenopus laevis oocytes. METHODS: An uptake study of (125)I-IMT was performed using transporter-expressed X. laevis oocytes. Oocytes were injected with 17.6 ng of hLAT1 or hLAT2 complementary RNA (cRNA) and 7.4 ng of h4F2hc cRNA in a molar ratio of 1:1. Two days after injection, the uptake of (125)I-IMT was measured in the Na(+)-free uptake solution containing 18.5 kBq of noncarrier-added (125)I-IMT. After incubation for 30 min at room temperature, radioactivity of the oocytes was determined. RESULTS: Of the 2 hLAT isoforms and h4F2hc-coexpressed X. laevis oocytes, (125)I-IMT uptake via hLAT1 was 5.95-fold higher than that via hLAT2 (P < 0.005). CONCLUSION: (125)I-IMT transport was hLAT1 selective. Investigations on the isoform selectivity of (125)I-IMT transport with other transporters are anticipated. (+info)
Functional and molecular characteristics of system L in human breast cancer cells. (7/46)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. (8/46)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)

To evaluate the expression of alanine-serine-cysteine-transporter 2 (ASCT2) and L-type amino acid transporter1 (LAT1) in prostate cancer (PCa) and their impact on uptake of 18F-1-amino-3-fluorocyclobutane-1-carboxylic acid (18F-fluciclovine) which is approved for the detection of recurrent PCa. 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. The correlations between ASCT2/LAT1 staining intensity, SUVmax/VT, and
Like normal cells, cancer cells require amino acids for growth, maintenance, and cell signaling, and L-type amino acid transporters (LATs) are the delivery vehicles that supply them.

Lysinuric protein intolerance (LPI), also called hyperdibasic aminoaciduria type 2,cationic aminoaciduria or familial protein intolerance, is an autosomal recessive metabolic disorder affecting amino acid transport. About 140 patients have been reported, almost half of them of Finnish origin. Individuals from Japan, Italy, Morocco and North Africa have also been reported. Infants with LPI are usually symptom-free when breastfed because of the low protein concentration in human milk, but develop vomiting and diarrhea after weaning. The patients show failure to thrive, poor appetite, growth retardation, enlarged liver and spleen, prominent osteoporosis and osteopenia, delayed bone age and spontaneous protein aversion. Forced feeding of protein may lead to convulsions and coma. Mental development is normal if prolonged episode of hyperammonemia can be avoided. Some patients develop severe pulmonary and renal complications. High levels of plasma glutamine and glycine are observed. It has been ...

NIH Rare Diseases : 50 lysinuric protein intolerance is a metabolic disorder caused by the bodys inability to digest and use the amino acids lysine, arginine, and ornithine. because the body cannot effectively break down these amino acids, which are found in many protein-rich foods, individuals experience nausea and vomiting after ingesting protein. other features associated with protein intolerance may also occur, including short stature, muscle weakness, impaired immune function, and osteoporosis. a lung disorder called pulmonary alveolar proteinosis may develop in some individuals, as can end-stage renal disease, coma and intellectual disability. symptoms usually develop after infants are weaned and begin to eat solid foods. lysinuric protein intolerance is caused by mutations in the slc7a7 gene. it is inherited in an autosomal recessive manner. last updated: 11/15/2010 ...
Lysinuric protein intolerance (LPI) is a rare autosomal recessive inborn error of metabolism, characterised by defective transport of the cationic amino acids lysine, arginine and ornithine. To date there are few reported necropsy cases. This report describes the necropsy findings in a 21 year old female patient originally diagnosed as having LPI in 1973. Liver function tests deteriorated and immediately before death jaundice, hyperammonaemia, coma, metabolic acidosis, and a severe bleeding diathesis developed. At necropsy, there was micronodular cirrhosis of the liver with extensive fatty change in hepatocytes. The lungs showed pulmonary alveolar proteinosis. Immunofluorescence and electron microscopy revealed the presence of a glomerulonephritis with predominant IgA deposition. These necropsy findings reflect the spectrum of lesions reported in LPI, providing further evidence of an association between this condition and pulmonary alveolar proteinosis, cirrhosis and glomerulonephritis.. ...
More than 40 mutations in the SLC7A7 gene have been found to cause lysinuric protein intolerance. All of these mutations impair the y+LAT-1 proteins ability to transport amino acids. People with lysinuric protein intolerance who are of Finnish descent typically have the same mutation. This mutation (written as IVS6-2A,T) disrupts the way the genes instructions are used to make the y+LAT-1 protein, causing the protein to be misplaced in the cell.. Mutations in the y+LAT-1 protein disrupt the transportation of amino acids, leading to a shortage of lysine, arginine, and ornithine in the body and an abnormally large amount of these amino acids in urine. The abnormal transportation and shortage of these amino acids in various tissues of the body leads to the signs and symptoms of lysinuric protein intolerance. ...

Characterization of the Human Ig Heavy Chain Antigen Binding Complementarity Determining Region 3 Using a Newly Developed...
We have developed a novel software algorithm, JOINSOLVER, to analyze the human CDR3H. Within the CDR3H, the definition of the D segment has been particularly problematic because of its short size and extensive terminal processing. Many attempts have been made to define the minimum length needed for D segment assignment (8, 21, 24, 25, 26, 36), yet there is still no consensus definition. Thus, we used novel methods to assign D segments. The first involved the use of a consecutive matching approach rather than the more standard alignment scoring system. The consecutive matching approach permitted the secure assignment of more D segments than the alignment scoring method. The second used methods to limit the search for identity to the VH-JH region only. Finally, a Monte Carlo simulation was used to determine the consecutive match necessary to assign a D segment. We opted to distinguish an actual D segment match from random sequence identity using a 95% probability. This level of confidence seems ...

SP-D counteracts GM-CSF-mediated increase of granuloma formation by alveolar macrophages in lysinuric protein intolerance |...
PAP in LPI is often untreatable and results in death. In this study, we carefully characterized BALF and tissue samples obtained from an LPI patient. The data revealed elevated levels of protein and dying cells in the airways. In addition, large cholesterol crystals and abnormal tubular myelin structures were found. Our primary cell culture assays using Alexa-647 conjugated BSA and apoptotic Jurkat T cells showed that pre-incubation of the LPI BAL cells with SP-D and GM-CSF increased their innate immune functions. Surprisingly, many of these LPI cells, but not the control cells, became elongated and stopped internalizing foreign material; eventually they formed granulomas ex vivo. Notably, treating these cells with GM-CSF ex vivo dramatically increased granuloma formation. However, treating the cells with SP-D reduced GM-CSF-mediated granuloma formation. Therefore, these findings may provide important clues for devising better treatment of PAP in LPI patients.. Although various SLC7A7 mutations ...
DMOZ - Health: Conditions and Diseases: Nutritional and Metabolic Disorders: Inherited: Lysinuric Protein Intolerance
LPI is an autosomally recessively inherited amino acid disorder due to defective transport of cationic amino acids lysine, arginine and ornithine in the intestine and kidney tubules. The absence or dysfunction of the transport process leads to low plasma and high urine concentration of the cationic (dibasic) amino acids. Clinical presentation of the disease usually takes place during the weaning period when breast feeding is replaced by cows milk and other high protein diets. Nausea, vomiting and mild diarrhea usually are the first symptoms followed by failure to thrive and growth retardation. Later liver and spleen become enlarged, muscles are hypotonic and osteoporosis can cause bone fractures. High protein intake can lead to hyperammonemia and even to coma, possibly accounting for the mild intellectual deficit found in few cases of LPI. Many patients have spontaneously developed aversion to protein rich food. A pulmonary complication of unknown mechanism, alveolar proteinosis has occurred in few
Breast feeding is the most nutritious form of nourishment in infants and is recommended for at least the first four months of life. Breast fed infants may develop milk protein intolerance. The management of breast milk protein intolerance differs from that of cows milk protein intolerance in formula fed infants. Because breast milk is considered by many to be nutritionally superior to formula and results in maternal infant bonding mothers are often told to continue breast feeding. Despite the lack of evidence based data to support or refute the modification of the mothers diet, it is suggested that they eliminate their own intake of dairy products strictly and avoid supplementing with a cows milk based formula. We are doing this study because we believe that deletion of dairy from the diet of a breast feeding mother will not cause BMPI to resolve ...
Mediation of Highly Concentrative Uptake of Pregabalin by L-Type Amino Acid Transport in Chinese Hamster Ovary and Caco-2 Cells...
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 ...

Thyroid Hormone Transporters in Mouse Neurons. Eva K. Wirth, Stephan Roth, Cristiane Blechschmidt, Sabine M. Hölter, Lore Becker, et al.. (see pages 9439-9449). The thyroid hormone 3′,3,5-triiodothyronine (T3) regulates transcription of genes that control all stages of brain development, from neuronal and glial proliferation to synaptogenesis and myelination. To exert these effects, T3 must be transported across plasma membranes and into cell nuclei where it binds to its receptors. The primary T3 transporter in neurons is monocarboxylate transporter 8 (MCT8), and the importance of this transporter is revealed by the fact that its mutation causes Allan-Herndon-Dudley syndrome, characterized by profound mental retardation, severe motor defects, and abnormally high plasma levels of T3. Surprisingly, mice lacking Mct8 show no overt behavioral abnormalities, although T3 levels are elevated. Wirth et al. performed extensive analyses and found no anatomical or motor defects, but mutant mice ...

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 ...

A "clean-catch" urine sample is performed by collecting the sample of urine in midstream. Men or boys should wipe clean the head of the penis. Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well.
