Holocarboxylase synthetase (HCS, human) and BirA (Escherichia coli) are biotin protein ligases that catalyze the ATP-dependent attachment of biotin to apocarboxylases. Biotin attachment occurs on a highly conserved lysine residue within a consensus sequence (Ala/Val-Met-Lys-Met) that is found in carboxylases in most organisms. Numerous studies have indicated that HCS and BirA, as well as biotin protein ligases from other organisms, can attach biotin to apocarboxylases from different organisms, indicating that the mechanism of biotin attachment is well conserved. In this study, we examined the cross-reactivity of biotin attachment between human and bacterial biotin ligases by comparing biotinylation of p-67 and BCCP87, the biotin-attachment domain fragments from human ...

U.S., Feb. 27 -- ClinicalTrials.gov registry received information related to the study (NCT03034707) titled Interference of Biotin Supplementation in Biotin-streptavidin Platforms for Hormone Testing on Jan. 17. Brief Summary: The B vitamin biotin is widely available as an over the counter supplement, often advertised and used to promote health of hair, skin and nails. Commercially available over the counter biotin supplements contain dose ranges up to 10 mg/day (ie 333 times higher than the recommended dietary allowance). The biotin molecule is also sometimes used as part of the lab technology to measure hormone and protein levels in the blood. It is possible that high doses of ingested biotin may interfere with accurate hormone or protein measurement using biotin related in vitro measurement systems. Such interference, if present, could lead to misdiagnosis. The study will analyze ...

3-Methylcrotonyl-CoA carboxylase deficiency (MCCC2-related) is a pan-ethnic, autosomal recessive disease caused by pathogenic variants in the MCCC2 gene. These variants impair the ability of the enzyme 3-methylcrotonyl-CoA carboxylase to break down proteins that contain the amino acid leucine. Presentation in childhood or early infancy is characterized by feeding difficulties, vomiting and diarrhea, excessive fatigue, and hypotonia. If detected early, the condition can be managed with a low-protein diet. If untreated, this disorder can eventually cause developmental delay, seizures, and coma. However, most individuals with this condition remain asymptomatic into adulthood. Life expectancy depends on the severity of presentation. No clear genotype-phenotype correlation has been noted.. For information about carrier frequency and residual risk, please see the Expanded Carrier Screen brochure.. ...

Biotinidase deficiency is an autosomal recessive metabolic disorder in which biotin is not released from proteins in the diet during digestion or from normal protein turnover in the cell. This situation results in biotin deficiency. Biotin, also called vitamin B7, is an important water-soluble nutrient that aids in the metabolism of fats, carbohydrates, and proteins. Biotin deficiency can result in behavioral disorders, lack of coordination, learning disabilities and seizures. Biotin supplementation can alleviate and sometimes totally stop such symptoms. Signs and symptoms of a biotinidase deficiency can appear several days after birth. These include seizures, hypotonia and muscle/limb weakness, ataxia, paresis, hearing loss, optic atrophy, skin rashes ...

An experiment was conducted to evaluate the effect of different levels of biotin on productive performance of Holstein dairy cow. In this experiment a change-over design with twelve multiparous cows, three rations and three periods was employed. Ingredients of the basal diet were alfalfa hay (24%) corn silage (16%) and concentrate (60%) on dry matter basis. The experimental diets 1 to 3 contained 0, 10 and 20 mg of biotin per day, respectively. The rations were fed to cows as Total Mixed Rations (TMR), but biotin was top-dressed on the a.m. allotment of ration. The cows were individually ad libitum and milked three times per day. Daily milk yielded was recorded and samples of the milk were taken once per week for determination of milk composition. Blood were taken in end of each period. Dry Matter Intake (DMI) and milk yield of cows were not affected by biotin. Also milk compositions were not affected by biotin. The average ...
Biotin (vitamin H or vitamin B7) is the essential cofactor of biotin-dependent carboxylases, such as pyruvate carboxylase and acetyl-CoA carboxylase. Mammals cannot synthesize biotin, while in bacteria, fungi, and plants it is synthesized from pimelate thioester through different pathways. In E. coli and many organisms, pimelate thioester is derived from malonyl-ACP. The pathway starts with the methylation to malonyl-ACP methyl ester, followed by the fatty acid chain elongation cycle to form pimeloyl-ACP methyl ester, which is then demethylated to form pimeloyl-ACP [MD:M00572]. Pimeloyl-ACP is converted to biotin through the final four steps in the biotin bicyclic ring assembly, which are conserved among biotin-producing organisms [MD:M00123]. In B. subtilis, biotin is derived from pimeloyl-ACP formed by oxidative cleavage of long-chain ...

Sensor performance of a dielectric filled silicon bulk acoustic resonator type label-free biosensor is verified with biotin-streptavidin binding interactions as a model system. The mass sensor is a micromachined silicon square plate with a dielectric filled capacitive excitation mechanism. The resonance frequency of the biotin modified resonator decreased 315 ppm when exposed to streptavidin solution for 15 min with a concentration of 10−7 M, corresponding to an added mass of 3.43 ng on the resonator surface. An additional control is added by exposing a bovine serum albumin (BSA)-covered device to streptavidin in the absence of the attached biotin. No resonance frequency shift was observed in the control experiment, which confirms the specificity of the detection. The sensor-to-sensor variability is also measured to be 4.3%. Consequently, the developed sensor can be used to observe in biotin-streptavidin interaction without the use of ...

Episodic ataxia can occur sporadically or in a number of hereditary disorders, like for instance in pyruvate carboxylase deficiency (PC gene) and pyruvate dehydrogenase deficiency (PDHA1 gene). In addition, mutations in the OTC gene, which may be evident as partial deficiency in females and complete deficiency in males, can cause episodic extreme irritability, episodic vomiting and lethargy, protein avoidance, ataxia, stage II coma, delayed growth, developmental delay, and seizures. Hyperammonemias caused by deficiencies of urea cycle enzymes (CPS1, ASS1, ASL, ARG1 gene mutations) are characterized by intermittent ataxia, dysarthria, vomiting, headache, ptosis, involuntary movements, seizures, and confusion. Aminoacidurias may also be a significant part of the differential diagnosis of episodic ataxias: Hartnup disease (SLC6A19 gene mutations), maple syrup ...

One of the most popular methods of noncovalent conjugation is to make use of the natural strong binding of avidin or its derivative streptavidin to biotin. Each avidin molecule contains a maximum of four biotin binding sites thereby increasing the strength of their interaction with biotin. Depending on the functionality present on the biotinylation compounds, specific reactive groups on antibodies may be modified to create a avidin binding site. Amines, carboxylates, sulfhydryls, and carbohydrate groups can be specifically targeted for biotinylation through the appropriate choice of biotin derivative.. Avidin is a glycoprotein found in egg whites that contains four identical subunits of 16,400 Da each. The subunits each contain one binding site for biotin also known as vitamin H. The biotin interaction with avidin is the strongest noncovalent affinity known, exhibiting a ...
3-Hydroxyisovalerylcarnitine is structual derivative of 3-hydroxyisovaleric acid and carnitine. Due to its increased concentration in blood, 3-hydroxyisovalerylcarnitine (C5OH-I) is an important indicator for the diagnosis of organic acidemias in newborns (PMID: 18088573 ). Analysis of acylcarnitines by tandem mass spectrometry (MS/MS) has recently been used to screen newborns for organic acidemias and fatty acid oxidation defects (PMID: 7494654 , 9216448 , 11427446 , 12127323 , 14578311 ). These diseases cause the accumulation of acyl-CoA, which is esterified to acylcarnitine by carnitine acyltransferase. Acylcarnitine is then eliminated in the urine, thus acylcarnitine concentration serves as an excellent indicator for these diseases (PMID: 6361812 ). 3-Hydroxyisovalerylcarnitine (C5OH-I) is an indicator for diagnoses of multiple carboxylase deficiency (MCD), 3-methylcrotonyl-CoA carboxylase ...
Excess intake of biotin is excreted in the urine no toxicity symptoms have been reported. Biotin works with some other B vitamins, such as folic acid, pantothenic acid vitamin B5, and vitamin B12. However, no solid evidence indicates that people supplementing with biotin also need to take these other vitamins. Symptoms of pantothenic acid or zinc deficiency have been reported to be lessened with biotin, though people with these deficiencies should supplement with the nutrients in which they are deficient. Researchers have speculated that biotin and alpha lipoic acid may compete with each other for absorption or uptake into cells but little is known about the importance of these interactions in humans. There is one report of a 76-year-old woman who developed a life-threatening condition eosinophilic pleuropericardial effusion while taking 10 mg of biotin per day and 300 mg of ...

The present study investigated the projections of the gigantocellular reticular nucleus (Gi) and its neighbors-the dorsal paragigantocellular reticular nucleus (DPGi), the alpha/ventral part of the gigantocellular reticular nucleus (GiA/V), and the lateral paragigantocellular reticular nucleus (LPGi)-to the mouse spinal cord by injecting the anterograde tracer biotinylated dextran amine (BDA) into the Gi, DPGi, GiA/GiV, and LPGi. The Gi projected to the entire spinal cord bilaterally with an ipsilateral predominance. Its fibers traveled in both the ventral and lateral funiculi with a greater presence in the ventral funiculus. As the fibers descended in the spinal cord, their density in the lateral funiculus increased. The terminals were present mainly in laminae 7-10 with a dorsolateral expansion caudally. In the lumbar and sacral cord, a considerable number of terminals were also present in laminae 5 and 6. Contralateral fibers shared a similar pattern to their ipsilateral counterparts and ...
Pharmacological manipulation of the ventrolateral pontine reticular formation (vlPRF) of rats has an anticonvulsant effect in the maximal electroshock model of epilepsy. This study presents three anatomical experiments that determine the efferent projections from this region likely to mediate this anticonvulsant effect. In the first, the anterograde tracer biotinylated dextran amine (BDA) was injected into the vlPRF. A strong projection to the ventromedial medullary reticular formation (vmMRF) was revealed which continued only weakly to the spinal cord. In the second experiment, double-label procedures were used to indicate whether the BDA-labelled terminals from the vlPRF make contacts with neurons in vmMRF, retrogradely labelled with cholera-toxin B subunit from the lumbar spinal cord. Sections of the vmMRF were examined by: (i) light microscopy which showed significant overlap between terminals from vlPRF and retrogradely-labelled reticulospinal cells; (ii) confocal microscopy which ...
Chromium Picolinate and Biotin Help Control Blood Sugar Levels. Researchers from Yale University have found that supplementation with chromium picolinate plus biotin can improve glycemic control in type 2 diabetic patients who are not responding to oral antihyperglycemic agents. Preclinical studies have shown that the combination of chromium picolinate and biotin significantly enhances glucose uptake in skeletal muscle cells and enhances glucose disposal. Researchers decided to determine how these two nutrients affect blood sugar control in humans. Forty-three obese or overweight subjects with impaired glycemic control despite treatments with oral antihyperglycemic agents were randomized to receive 600 micrograms of chromium picolinate and 2 mg of biotin per day. Researchers measured glycemic control and blood lipids at baseline and after 4 weeks. There was a significant reduction in glucose during the 2-hour oral glucose tolerance test in ...

Following unilateral lesion of the primary motor cortex, the reorganization of callosal projections from the intact hemisphere to the ipsilesional premotor cortex (PM) was investigated in 7 adult macaque monkeys, in absence of treatment (control; n = 4) or treated with function blocking antibodies against the neurite growth inhibitory protein Nogo-A (n = 3). After functional recovery, though incomplete, the tracer biotinylated dextran amine (BDA) was injected in the ipsilesional PM. Retrogradely labelled neurons were plotted in the intact hemisphere and their number was normalized with respect to the volume of the core of BDA injection sites. (1) The callosal projections to PM in the controls originate mainly from homotypic PM areas and, but to a somewhat lesser extent, from the mesial cortex (cingulate and supplementary motor areas). (2) In the lesioned anti-Nogo-A antibody-treated monkeys, the normalized number of callosal retrogradely labelled neurons was up to several folds higher than ...
Abstract The avidin-biotin-peroxidase complex enzyme-linked immunosorbent assay (ABC-ELISA) and standard ELISA were used for the detection of Echinococcus granulosus antibody in sera of 101 patients operated on for hydatid disease, 40 patients with miscellaneous nonhydatid diseases, and 61 normal subjects. Sensitivity and specificity of the two procedures were comparable and the geometric mean antibody titer detected with ABC-ELISA was higher than with standard ELISA. The ABC-ELISA is a sensitive, specific, simple, and convenient method for diagnosing hydatidosis.
Rationale: S-nitrosylation (SNO), an oxidative post-translational modification of cysteine residues, responds to changes in the cardiac redox-environment. Classic biotin switch assay and its derivatives are the most common methods used for detecting SNO. In this approach, the labile SNO group is selectively replaced with a single stable tag. To date, a variety of thiol-reactive tags have been introduced. However, these methods have not produced a consistent dataset which suggests an incomplete capture by a single tag and potentially the presence of different cysteine subpopulations. Objective: To investigate potential labeling bias in the existing methods with a single tag to detect SNO, explore if there are distinct cysteine subpopulations, and then, develop a strategy to maximize the coverage of SNO proteome. Methods and Results: We obtained SNO-modified cysteine datasets for wild-type and S-nitrosoglutathione reductase (GSNOR) knock-out mouse hearts (GSNOR is a negative regulator of GSNO ...
A method is described for localizing DNA sequences hybridized in situ to Drosophila polytene chromosomes. This procedure utilizes a biotin-labeled analog of TTP that can be incorporated enzymatically into DNA probes by nick-translation. After hybridization in situ, the biotin molecules in the probe serve as antigens which bind affinity-purified rabbit antibiotin antibodies. The site of hybridization is then detected either fluorimetrically, by using fluorescein-labeled goat anti-rabbit IgG, or cytochemically, by using an anti-rabbit IgG antibody conjugated to horseradish peroxidase. When combined with Giemsa staining, the immunoperoxidase detection method provides a permanent record that is suitable for detailed cytogenetic analysis. This immunological approach offers four advantages over conventional autoradiographic procedures for detecting in situ hybrids: (i) the time required to determine the site of hybridization is decreased markedly, (ii) ...
Non-covalent binding of avidin to biotinylated erythrocytes results in complement-dependent haemolysis. Biotinylated erythrocytes, as well as native cells, are not lysed by complement. Complement activation requires a tight contact between avidin and the erythrocyte membrane, since avidin does not in itself activate complement and does not inhibit lysis of sensitized sheep erythrocytes. The efficiency of haemolysis depends on avidins surface density. When the avidin concentration in the reaction mixture is less than 15 micrograms/ml, erythrocyte lysis is not induced. However, the attachment of biotinylated antibodies to avidin-carrying erythrocytes decreases dramatically. Acylation of avidin with succinic anhydride strongly decreases its ability to induce complement-dependent haemolysis. However, the ability of avidin to cross-link the biotin-containing structures decreases after acylation. A 50% modification of avidin by succinic anhydride ...

Minerals: Their RDAs, actual requirements, pharmacologic doses, sources, effects, toxicity symptoms, deficiency symptoms, inhibitors & enhancers. 4/ All body processes depend on the action of minerals. All nutrients require minerals for processing and activity. 5/ Minerals are more important than vitamins. Vitamins are required for every biochemical activity of the body. Vitamins require minerals to enable their functions. Minerals catalyse and enable enzymes to function. Glandular hormone secretions are dependent upon mineral stimulation. PH of the tissue fluid is controlled by minerals. Pumping Action of the cell, allowing transfer of cell nutrients and waste, is controlled by minerals. One mineral deficiency is enough to disrupt the entire body balance. Mineral supplementation is critical to support body functions and maintain or develop health. These facts about minerals apply to plants, animals and man to differing degrees. In all forms ...
A first treatment strategy is to enhance the reduced enzyme activity. Gene replacement is a long-term goal, but problems of gene delivery to target organs and control of gene action make this an unrealistic option at present. Enzyme-replacement therapy using intravenously administered recombinant enzyme has been developed as an effective strategy in lysosomal storage disorders. Organ transplantation (liver or bone marrow) can provide a source of enzyme for some conditions. Pharmacologic doses of a cofactor such as a vitamin can sometimes be effective in restoring enzyme activity. Residual activity can be increased by pharmacologically promoting transcription (transcriptional upregulation) or by stabilizing the protein product through therapy with chaperones. Alternatively, some strategies are designed to cope with the consequences of enzyme deficiency. Strategies used to avoid substrate accumulation include restriction of precursor in the diet (eg, low-phenylalanine diet for ...
The term vitamin D-resistant rickets (VDRR) originally was used to describe a syndrome of hypophosphatemia and rickets (and/or osteomalacia) that resembled vitamin D deficiency but did not respond to vitamin D replacement or pharmacologic doses of vi
OUTLINE: This is a dose deescalation study of azacitidine.. Patients receive azacitidine subcutaneously daily on days 1-5 and 29-33 followed by phenylbutyrate IV continuously on days 5-12 and 33-40. Treatment continues for at least 2 courses in the absence of disease progression. Patients with responsive disease may receive an additional 2 months of therapy.. Cohorts of 3-6 patients receive deescalating doses of azacitidine until the minimal effective pharmacologic dose (MEPD) is determined. The MEPD is defined as the dose above the dose at which more than 1 of 6 patients do not meet the target enzyme inhibition of greater than 90%.. Once the MEPD and toxicity have been established for a 5 day schedule, daily dose schedule of azacitidine is increased to 10, 14, and 21 days, followed by phenylbutyrate for 7 days. Courses are repeated every 28 days.. PROJECTED ACCRUAL: Approximately 32 patients will be accrued for this study within 2 years. ...
Alternate day therapy is a corticosteroid dosing regimen in which twice the usual daily dose of corticoid is administered every other morning. The purpose of this mode of therapy is to provide the patient requiring long-term pharmacologic dose treatment with the beneficial effects of corticoids while minimizing certain undesirable effects, including pituitary-adrenal suppression, the Cushingoid state, corticoid withdrawal symptoms, and growth suppression in children.. The rationale for this treatment schedule is based on two major premises: (a) the anti-inflammatory or therapeutic effect of corticoids persists longer than their physical presence and metabolic effects and (b) administration of the corticosteroid every other morning allows for reestablishment of more nearly normal hypothalamic-pituitary-adrenal (HPA) activity on the off-steroid day.. A brief review of the HPA physiology may be helpful in understanding this rationale. Acting primarily through the hypothalamus a fall in free ...
TY - JOUR. T1 - L-Carnitine is a modulator of the glucocorticoid receptor alpha. AU - Alesci, Salvatore. AU - De Martino, Massimo U.. AU - Kino, Tomoshige. AU - Ilias, Ioannis. PY - 2004/1/1. Y1 - 2004/1/1. N2 - L-Carnitine (LC) is a nutrient with an essential role in cellular energy production. At high doses, LC can mimic some of the biological activities of glucocorticoids, particularly immunomodulation. To explore the molecular bases of this property, we tested the influence of LC on glucocorticoid receptor-α (GRα) functions. LC reduced the binding capacity of GRα, induced its nuclear translocation, and stimulated its transcriptional activity. Moreover, LC suppressed TNFα and IL-12 release from human monocytes in glucocorticoid-like fashion. We conclude that pharmacologic doses of LC can activate GRα and, via this mechanism, regulate glucocorticoid-responsive genes, potentially sharing some of the biological and therapeutic properties of glucocorticoids.. AB - L-Carnitine (LC) is a ...
Resveratrol has been shown to exhibit cancer-preventive activities in preclinical studies. We conducted a clinical study to determine the effect of pharmacologic doses of resveratrol on drug- and carcinogen-metabolizing enzymes. Forty-two healthy volunteers underwent baseline assessment of cytochrome P450 (CYP) and phase II detoxification enzymes. CYP1A2, CYP2D6, CYP2C9, and CYP3A4 enzyme activities were measured by the metabolism of caffeine, dextromethorphan, losartan, and buspirone, respectively. Blood lymphocyte glutathione S-transferase (GST) activity and GST-π level and serum total and direct bilirubin, a surrogate for UDP-glucuronosyl transferase (UGT) 1A1 activity, were measured to assess phase II enzymes. After the baseline evaluation, study participants took 1 g of resveratrol once daily for 4 weeks. Enzyme assessment was repeated upon intervention completion. Resveratrol intervention was found to inhibit the phenotypic indices of CYP3A4, CYP2D6, and CYP2C9 and to induce the ...
The essential features of X-linked sideroblastic anemia include the following: (1) a hypochromic microcytic anemia and 2 discrete populations of red blood cells, one microcytic and the other normocytic; (2) marrow ringed sideroblasts, particularly prominent in the late erythroid precursors; (3) a variable hematologic response to pharmacologic doses of pyridoxine; and (4) systemic iron overload secondary to chronic ineffective erythropoiesis. The age of clinical onset of the disorder can vary from in utero to the ninth decade. Whereas males are preferentially affected, females may present with clinically severe anemia. More commonly, female carriers of the disease have an increased red blood cell distribution width and sometimes erythrocyte dimorphism ({18:Fleming, 2002 ...
Both nicotinic acid and nicotinamide are white, odorless, crystalline solids soluble in water and alcohol. They are very resistant to heat, air, light and alkali and thus are stable in feeds. Niacin is also stable in the presence of the usual oxidizing agents. However, it will undergo decarboxylation at a high temperature, when in an alkaline medium. An important source of niacin for ruminants is ruminal synthesis. Synthesis of niacin in the rumen has been demonstrated in sheep (Rérat et al., 1959), cattle (Hungate, 1966) and goats (Porter, 1961). This synthesis also has been suggested to be under metabolic control; e.g., more is synthesized when small amounts are provided in the ration and vice versa (Porter, 1961; Abdouli and Schaefer, 1986). Nicotinic acid and its amide are readily and very efficiently absorbed by diffusion at either physiological or pharmacologic doses. The mechanism by which nicotinamide nucleotides present in animal feeds are absorbed, however, is unknown. Whether the ...
Background: Cell proliferation occurs not only in normal but also in cancer cells. Most of cell proliferation inhibition can be done by inhibiting the DNA synthesis, notably by intervening the formation of purine or pyrimidine. In purine de novo synthesis, it was assumed that biotin plays a role as a coenzyme in carboxylation reaction, one of the pivotal steps in the purine de novo pathways. The aim of this study was to see the avidin potency to bind biotin and inhibit mitosis.. Methods: Peripheral blood mononuclear cell (PBMC) was cultured in RPMI-1640 medium and stimulated by phytohemagglutinin (PHA) in the presence or absence of interleukin-2 (IL-2), with or without avidin. The effect of avidin addition was observed at 24, 48, and 72 hours for cell proliferation, viability, and cell cycle. Statistical analysis was done by one-way ANOVA.. Results: Avidin inhibited cell proliferation and viability in culture under stimulation by PHA with and without IL-2. Cell cycle ...
There is much debate as to the clinical significance of 3-methylcrotonyl-CoA carboxylase deficiency (3MCC deficiency). In thinking about this issue, I recently read a paper by Arnold et al, (Mol Genet Metab. 2012 Aug;106(4):439-41) that describes their retrospective analysis of 35 cases of 3-MCC deficiency identified by newborn screening and confirmed by enzyme and/or molecular analysis. One of the most […]. ...
New technology enables expansion of newborn screening (NBS) of inborn errors aimed to prevent adverse outcome. In conditions with a large share of asymptomatic phenotypes, the potential harm created by NBS must carefully be weighed against benefit. Policies vary throughout the United States, Australia, and Europe due to limited data on outcome and treatability of candidate screening conditions. We elaborated the rationale for decision making in 3-methylcrotonyl-coenzyme A (CoA) carboxylase deficiency (MCCD), which afflicts leucine catabolism, with reported outcomes ranging from asymptomatic to death. In Bavaria, we screened 677,852 neonates for 25 conditions, including MCCD, based on elevated concentrations of 3-hydroxyisovalerylcarnitine (3-HIVA-C). Genotypes of MCCA (MCCC1) and MCCB (MCCC2) were assessed in identified newborns, their relatives, and in individuals (n = 17) from other regions, and correlated to biochemical and clinical phenotypes. NBS ...

What are the symptoms of brittle nails?. People with brittle nails may have frequent or easy breaking, cracking, splitting, or tearing of their nails.. Nutritional supplements that may be helpful for brittle nails. Nutrition can affect the health of nails in a variety of ways. Iron deficiency may cause spoon-shaped nails.1 For years, some doctors have believed zinc deficiency causes white spots to appear on nails. In China, excessive selenium has been linked to nails actually falling out.2. Biotin, a B vitamin, is known to strengthen hooves in animals. As a result, Swiss researchers investigated the use of biotin in strengthening brittle fingernails in humans, despite the fact that it remains unclear exactly how biotin affects nail structure. An uncontrolled trial of 2.5 mg biotin per day found improved firmness and hardness in almost all cases after an average treatment ...
10-plate (plates NOT included). Monoclonal antibody to human perforin. Mouse IgG|sub|1. Biotinylated monoclonal antibody to human perforin. Mouse IgG|sub|1. The usefulness of sandwich ELISAs (enzyme-linked immunosorbent assays) in cytokine biology is evident from the many reports published on this subject. The assay requires two antibodies (either mono- or polyclonal antibodies) that bind with high affinity to different sites on the cytokine molecule. One of the antibodies is immobilized to the wells of a 96-well microtiter plate. This so-called capture or coating antibody functions to selectively immobilize the cytokine from crude protein preparations. The second antibody (detection antibody) is labeled with biotin and binds to a different site on the cytokine molecule. Biotin allows the antibody to interact with streptavidin molecules. By using HRP (horseradish peroxidase)-labeled streptavidin, the cytokine can now quantitatively be determined by enzymatic ...
The characterization of the repertoire of proteins exposed on the cell surface by Mycoplasma hyopneumoniae (M. hyopneumoniae), the etiological agent of enzootic pneumonia in pigs, is critical to understand physiological processes associated with bacterial infection capacity, survival and pathogenesis. Previous in silico studies predicted that about a third of the genes in the M. hyopneumoniae genome code for surface proteins, but so far, just a few of them have experimental confirmation of their expression and surface localization. In this work, M. hyopneumoniae surface proteins were labeled in intact cells with biotin, and affinity-captured biotin-labeled proteins were identified by a gel-based liquid chromatographytandem mass spectrometry approach. A total of 20 gel slices were separately analyzed by mass spectrometry, resulting in 165 protein identifications corresponding to 59 different protein species. The identified surface exposed proteins better defined the set of M. ...
We have previously reported strategies for Escherichia coli production of recombinant immunogens fused to hydrophobic peptides or lipid tags to improve their capacity to be incorporated into an adjuvant formulation, e.g., immunostimulating complexes (iscoms). Recently, we also explored the strong interaction between biotin and streptavidin to achieve iscom association of recombinant immunogens. Plasmodium falciparum, Toxoplasma gondii and Neospora caninum antigens have served as model immunogens in the different studies. Generated fusion proteins have been found to be successfully incorporated into iscoms and high-titer antigen-specific antibody responses have been obtained upon immunization of mice. We believe that the different concepts presented, utilizing either hydrophobic peptide or lipid tags, or the recently explored biotin-streptavidin principle, offer convenient methods to achieve efficient adjuvant incorporation of recombinant immunogens.. ...
Adenoviral vectors have great potential for use in gene therapy and genetic immunization. The targeting of Ad vectors to the relevant tissue and cell types in vivo could greatly improve their safety and performance by lowering the effective dosage required for therapeutic levels of gene expression. Redirection of Ad vector tropism will require physical modifications of the adenoviral capsid but direct genetic modification of the Ad capsid has so far been limited to small peptides. A novel system for the attachment of targeting ligands to the Ad capsid, based on the extremely strong avidin-biotin interaction, is described herein. The genetic insertion of a biotin acceptor peptide (BAP) into the fiber, protein IX, or hexon components of the Ad capsid has resulted in vectors that are metabolically biotinylated upon production in host cells. Avidin-dependent redirection of transduction through a variety of biotinylated ligands is greatly ...

The molecular basis of C7 deficiency has been investigated in two Irish families and a number of Israeli families of Moroccan Sephardic Jewish origin. Exon PCR and sequencing revealed a heterozygous point mutation at the 3 splice acceptor site of intron 1 in one Irish family. In the other Irish family, exons 7 and 8 failed to amplify and they were shown to be deleted. Marker haplotype studies of the C6 and C7 gene region and Southern blots show that the Irish family with the splice defect also segregate for the deletion, which is not easily detected in heterozygotes. The Israeli C7-deficient cases all share a C7 haplotype and are homozygous for a mis-sense mutation in exon 9. However, one individual is heterozygous for markers at adjacent C6 loci, showing that there has been an intergenic recombination and suggesting that the deficiency mutation is of appreciable antiquity. ...
Phenylketonuria (PKU) is caused by a defect in the conversion of the amino acid phenylalanine (Phe) to tyrosine (Tyr). Without treatment, patients develop mental retardation. Inclusion of the Phe/Tyr ratio has decreased the number of false positive screening outcomes to the present PPV of 0.92 without any known missed cases. The recall levels have been lowered several times since the start of screening. An increase in the incidence of patients with milder disease has been observed with time. We were able to show that the impact of the adjusted recall levels was low. Instead, milder genetic variants, which are more common in Southern Europe, are found more often, which is an effect of the large number of non-Nordic immigrants who have come to Sweden during the last 25 years. The immigration has widened the spectrum of detected pathogenic variants ...

When part of the immune system malfunctions or is absent, an immune deficiency disease can develop. Immune deficiency diseases are bred either from an inborn immune system cell defect (primary immune deficiency disease) or from an extrinsic environmental agent (secondary immune deficiency disease). Example: AIDS is caused by an extrinsic force (HIV) and is therefore a secondary immune deficiency disease. Autoimmune diseases such as multiple sclerosis and lupus affect the tissue that connects the body tissue and organs, triggering a breakdown in the immune system ...
A possible genetic basis should be considered in children with metabolic acidosis not attributable to another disorder, especially if the acidosis cannot be explained by elevated lactate and/or ß-hydroxybutyrate.. Blood gas arterial or venous.. Organic acids urine (collected during acidotic episode); a normal result, when not acutely ill, does not exclude these disorders. In some diseases (eg, biotinidase deficiency) metabolic acidosis may not occur, but the abnormal organic acids can be detected in the urine.. Identification of the specific disorder depends on the pattern of organic acids excreted during attacks.. Ammonia and Glucose should be measured, as many organic acidaemias are associated with hyperammonaemia and/or hypoglycaemia.. See also Hyperammonaemia, Hypoglycaemia. Naming of specific disorders is usually based on the acid(s) excreted or the deficient enzyme(s).. ...

NIH clinicians have cared for people with unusual and difficult-to-treat immune disorders for decades," says NIAID Director Anthony S. Fauci, M.D. "This study exemplifies their commitment to improving the lives of people with these diseases by trying to uncover the causes of these disorders and thereby better understanding how to treat them.". Combined immunodeficiency is a type of primary immune deficiency disease (PIDD) in which several parts of the immune system are affected. This inherited disorder is characterized by increased susceptibility to bacterial, viral and fungal infections of various organs of the body. In some cases, susceptibility to cancers also may be seen.. There are 150 known PIDDs. Approximately 500,000 people in the United States have been diagnosed with a PIDD, while many more remain undiagnosed.. The NIAID and NCI investigators recognized that certain patients with an undefined form of combined ...
Diseases that are caused by the lack of some particular nutrient in a persons diet are called deficiency diseases. A child having this disease is unable to see properly in the dark. His eyes become dull and listless and the skin becomes dry. If not treated in time, the child may become blind.

the basic problem itself is straightforward: RNase is an enzyme produced by the human body when it is attacked by viruses or bacteria. as the name implies, RNase denatures messenger RNA wherever it find its. as it comes in contact with the invading virus or bacteria, it destroys its RNA and thus kills the invader. this is a very quick-acting defense mechanism, unlike the slower production of T cells, B cells, etc., which can take days or even weeks, and thus is one of the bodys first lines of defense. in REDD, the mechanism that produces RNase is damaged by any number of causes, the most notable being environmental toxins. in 1985, in incline village, north lake tahoe, there was what has now become a very famous outbreak of REDD, where over 200 people came down with it (i was one of the lucky 200. treya and i were in tahoe recovering from her latest round of intensive chemotherapy). a widely circulated hypothesis is that this outbreak was triggered by a local toluene spill, but nobody really ...
