Expression of heteromeric amino acid transporters along the murine intestine. (1/5)

Members of the new heterodimeric amino acid transporter family are composed of two subunits, a catalytic multitransmembrane spanning protein (light chain) and a type II glycoprotein (heavy chain). These transporters function as exchangers and thereby extend the transmembrane amino acid transport selectivity to specific amino acids. The heavy chain rBAT associates with the light chain b degrees (,+)AT to form a cystine and cationic amino acid transporter. The other heavy chain, 4F2hc, can interact with seven different light chains to form various transporters corresponding to systems L, y(+)L, asc or x(-)(c). The importance of some of these transporters in intestinal and renal (re)absorption of amino acids is highlighted by the fact that mutations in either the rBAT or b degrees (,+)AT subunit result in cystinuria whereas a defect in the y(+)-LAT1 light chain causes lysinuric protein intolerance. Here we investigated the localization of these transporters in intestine since both diseases are also characterized by altered intestinal amino acid absorption. Real time PCR showed organ-specific expression patterns for all transporter subunit mRNAs along the intestine and Western blotting confirmed these findings on the protein level. Immunohistochemistry demonstrated basolateral coexpression of 4F2hc, LAT2 and y(+)-LAT1 in stomach and small intestine, whereas rBAT and b degrees (,+)AT were found colocalizing on the apical side of small intestine epithelium. In stomach, 4F2hc and LAT2 were localized in H(+)/K(+)-ATPase-expressing parietal cells. The abundant expression of several members of the heterodimeric transporter family along the murine small intestine suggests their involvement in amino acids absorption. Furthermore, strong expression of rBAT, b degrees (,+)AT and y(+)-LAT1 in the small intestine explains the reduced intestinal absorption of some amino acid in patients with cystinuria or lysinuric protein intolerance.  (+info)

Successful whole lung lavage in pulmonary alveolar proteinosis secondary to lysinuric protein intolerance: a case report. (2/5)

BACKGROUND: Pulmonary alveolar proteinosis (PAP) is a rare disease characterised by accumulation of lipoproteinaceous material within alveoli, occurring in three clinically distinct forms: congenital, acquired and secondary. Among the latter, lysinuric protein intolerance (LPI) is a rare genetic disorder caused by defective transport of cationic amino acids. Whole Lung Lavage (WLL) is currently the gold standard therapy for severe cases of PAP. CASE PRESENTATION: We describe the case of an Italian boy affected by LPI who, by the age of 10, developed digital clubbing and, by the age of 16, a mild restrictive functional impairment associated with a high-resolution computed tomography (HRCT) pattern consistent with pulmonary alveolar proteinosis. After careful assessment, he underwent WLL. CONCLUSION: Two years after WLL, the patient has no clinical, radiological or functional evidence of pulmonary disease recurrence, thus suggesting that WLL may be helpful in the treatment of PAP secondary to LPI.  (+info)

Specific membrane transporters mediate the passage of a wide variety of substances across cellular membranes. Classes of substrates include amino acids, sugars, cations, anions, vitamins, and water. The number of inherited disorders of membrane transport continues to increase with the identification of new transporters on the plasma membrane or intracellular organelles and the clarification of the molecular basis of diseases with previously unknown pathophysiology. The first transport disorders identified affected the gut or the kidney, but transport processes are now proving essential for the normal function of every organ. Mutations in transporter molecules cause disorders of the heart, muscle, brain, and endocrine and sensory organs (Table 435e-1). Inherited defects impairing the transport of selected amino acids that can present in adults are discussed here as examples of the abnormalities encountered; others are considered elsewhere in this text. ...
Genetics Home Reference : 25 Lysinuric protein intolerance is a disorder caused by the bodys inability to digest and use certain protein building blocks (amino acids), namely lysine, arginine, and ornithine. Because the body cannot effectively break down these amino acids, which are found in many protein-rich foods, nausea and vomiting are typically experienced after ingesting protein. People with lysinuric protein intolerance have features associated with protein intolerance, including an enlarged liver and spleen (hepatosplenomegaly), short stature, muscle weakness, impaired immune function, and progressively brittle bones that are prone to fracture (osteoporosis). A lung disorder called pulmonary alveolar proteinosis may also develop. This disorder is characterized by protein deposits in the lungs, which interfere with lung function and can be life-threatening. An accumulation of amino acids in the kidneys can cause end-stage renal disease (ESRD) in which the kidneys become unable to filter ...

Pathogenic variants in the ATP7A gene result in several metabolic disorders (eg, Menkes disease) related to copper uptake and serum copper concentrations. Low copper concentration leads to progressive intellectual delay, bone and skeletal abnormalities, changes to skin and hair structure, hypotonia, and seizures. Symptoms of Menkes disease are progressive. Individuals are typically healthy from birth to 3-5 months, when the infant begins to lose developmental skills. Because of the wide spectrum of phenotypic severity and the progressive nature of symptoms, life expectancy is difficult to predict. Individuals diagnosed as children typically do not survive past early childhood, although some individuals respond to treatment with an improved quality of life and longer life expectancy. A diagnosis of Menkes disease is confirmed by genetic testing.. ...
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
Iminoglycinuria, sometimes called familial iminoglycinuria, is an autosomal recessive disorder of renal tubular transport affecting reabsorption of the amino acid glycine, and the imino acids proline and hydroxyproline. This results in excess urinary excretion of all three acids (-uria denotes in the urine). Iminoglycinuria is a rare and complex disorder, associated with a number of genetic mutations that cause defects in both renal and intestinal transport systems of glycine and imino acids. Imino acids typically contain an imine functional group, instead of the amino group found in amino acids. Proline is considered and usually referred to as an amino acid, but unlike others, it has a secondary amine. This feature, unique to proline, identifies proline also as an imino acid. Hydroxyproline is another imino acid, made from the naturally occurring hydroxylation of proline. The primary characteristic of iminoglycinuria is the presence of glycine and imino acids in the urine. Otherwise, it is ...
Research focuses on the elucidation of the molecular mechanisms underlying epithelial transport disorders including kidney and small intestine. The major emphasis is currently on the novel epithelial calcium (TRPV5 & TRPV6) and magnesium (TRPM6 & TRPM7) channels that constitute the rate-limiting calcium / magnesium influx pathways in epithelia. In addition, they investigate the role of renal sodium transporters (NKCC2, NCC, ENaC) in essential hypertension and contribute to the multidisiplinary effort to establish a biokidney.

The problem of how a gradual development of ecological and morphological adaptations combines with large genome rearrangements, which have been found to occur in the phylogeny of many groups of organisms, is a matter of discussion in the literature. The objective of this work was to study the problem with the example of salmonids, whose evolution included at least six events of multiple chromosome fusions. Large karyotype rearrangements are associated with a decrease in ecological and morphological diversity in salmonids. In the above example, genome rearrangements seem to distort the function of the genetic systems that are responsible for the occurrence of certain ecological forms in salmonids.

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 ...
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. ...
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 ...
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 ...
Lysinuric protein intolerance (LPI) [MIM:222700]: A metabolic disorder characterized by increased renal excretion of cationic amino acid (CAA), reduced CAA absorption from intestine, and orotic aciduria. On a normal diet, LPI patients present poor feeding, vomiting, diarrhea, episodes of hyperammoniaemic coma and growth retardation. Hepatosplenomegaly, osteoporosis and a life-threatening pulmonary involvement (alveolar proteinosis) are also seen. Biochemically LPI is characterized by defective transport of dibasic amino acids at the basolateral membrane of epithelial cells in kidney and intestine. {ECO:0000269,PubMed:10080182, ECO:0000269,PubMed:10631139, ECO:0000269,PubMed:10655553, ECO:0000269,PubMed:12402335, ECO:0000269,PubMed:15756301, ECO:0000269,PubMed:15776427, ECO:0000269,PubMed:17764084, ECO:0000269,PubMed:9829974}.

Lysine and its bioactive form L-lysine, abbreviated Lys or L, is an essential amino acid. Normal requirements for adults are between 8 g per day or 12 mg/kg. Children and infants need more: 44 mg/kg per day for an eleven to-twelve-year old, and 97 mg/kg per day for three-to six-month old. Lysine is highly concentrated in muscle compared to most other amino acids. Normal lysine metabolism is dependent upon many nutrients including niacin, vitamin B6, riboflavin, vitamin C, glutamic acid and iron. Several inborn errors of lysine metabolism are known, such as cystinuria, hyperdibasic aminoaciduria I, lysinuric protein intolerance, propionic acidemia, and tyrosinemia I. Most are marked by mental retardation with occasional diverse symptoms such as absence of secondary sex characteristics, undescended testes, abnormal facial structure, anemia, obesity, enlarged liver and spleen, and eye muscle imbalance. Low lysine levels have been found in patients with Parkinsons, hypothyroidism, kidney disease, ...

A 40-year-old mother of seven who did not smoke developed progressive dyspnoea that had persisted for 6 months. She was diagnosed with PAP in another hospital in 2005 by bronchoalveolar lavage and transbronchial biopsy. There she was treated with three whole lung lavages. When she arrived at our institution she was dyspnoeic at rest, her room air saturation was 84%, requiring 3 l of oxygen via nasal cannula. She underwent whole lung lavages in July and November 2005 and her saturation improved to 89-95% on room air during rest and 87% during effort; 0.5-1 l oxygen was administered via a nasal cannula.. At the beginning of January 2006, 5 mg/kg GM-CSF (Leukine; Bayer Healthcare Pharmaceuticals Inc, Leverkusen, Germany) was administered daily. Some improvement (better oxygenation and lung function tests) was demonstrated clinically, but there was no radiographic improvement.. A year later her dyspnoea increased and increasing amounts of supplemental oxygen were required. By February 2007 her ...

Chronic myeloid leukemia (CML) patients treated with imatinib develop frequent resistance generally due to a point mutation. Recently, large rearrangements of abl sequence have also been described. In this study, we focused on the complete deletion of exon 7. We screened for bcr-abldelexon7 in 63 resistant patients by high-resolution melting (HRM) analysis and direct sequencing. Moreover, we analyzed expression of abldelexon7 and bcr-abldelexon7 in 17 CML patients at diagnosis, 32 patients at resistance, and 20 negative controls by quantitative PCR or fragment length analysis. bcr-abldelexon7 was detected on 34 (54%) among 63 resistant patients by HRM, showing an increase in the sensitivity of screening, because only 3.2% could be detected by direct sequencing. This deletion was not associated with a point mutation (P = 0.3362). In addition, abldelexon7 was found in all tested samples with the same pattern of expression, suggesting an alternative splicing mechanism. In the bcr-abl component, ...

Introduction: Pulmonary alveolar proteinosis (PAP) is a rare disease characterised by the abnormal accumulation of surfactant-like material in macrophages within the alveolar spaces and distal bronchioles. The course of the disease is variable and the prognosis is often good. However, progressive disease in some patients can cause respiratory dysfunction and can be life threatening. In this situation, the only effective treatment is whole lung lavage. The objective of the study was to present the characteristics and the course of pulmonary alveolar proteinosis in our own material, the diagnostic methods used, the indications for treatment and the treatment efficacy.. Material and methods: Retrospective analysis included 17 patients: 6 women and 11 men, aged from 32 to 56 years, who were observed in the Third Lung Department of Pneumonology at the National Institute of Tuberculosis and Lung Diseases between 1984 and 2013. In all patients chest X-ray, pulmonary function test and blood gases were ...

The results may in part explain why the immune system is impaired with age. During a persons life, continuous alterations in the cells DNA occur. The alterations can be changes to the individual building blocks of the DNA but more common are rearrangements where large DNA segments change place or direction, or are duplicated or completely lost. In the present study the scientists examined normal blood cells from identical (monozygotic) twins in different age groups and looked for large or smaller DNA rearrangements. The results showed that large rearrangements were only present in the group older than 60 years. The most common rearrangement was that a DNA region, for instance a part of a chromosome, had been lost in some of the blood cells. Certain, almost identical, rearrangements were found in several individuals and some of these could be correlated with a known blood disease in which the bone marrows capacity to produce new blood cells is disturbed. Rearrangements were also found in the ...

From the mid-1990s onward, screening of the BRCA1 and BRCA2 genes has been routinely done in genetic diagnostic laboratories to identify mutations predisposing to breast and ovarian cancer. All laboratories analyze the coding sequence and intron-exon junctions by direct sequencing or prescreening methods followed by sequencing. Most of them, at least in Europe, also search for large rearrangements using semiquantitative PCR-based methods such as MLPA (12) or QMPSF (11). In some laboratories, mRNA analyses are conducted for high-risk families as a second step when no mutation is identified on genomic DNA. Indeed, mRNA analysis represents an effective tool for the identification of yet undiscovered molecular defects of the BRCA1/2 genes such as gene inversion, or splicing alterations. With regard to the detection of this latter class of mutations, much progress has been accomplished in the recent years because of the development of in silico tools that can more or less efficiently predict the ...
