Role of iron in Nramp1-mediated inhibition of mycobacterial growth. (1/3516)

Innate resistance to mycobacterial growth is mediated by a gene, Nramp1. We have previously reported that Nramp1 mRNA from macrophages of Mycobacterium bovis BCG-resistant (Bcgr) mice is more stable than Nramp1 mRNA from macrophages of BCG-susceptible (Bcgs) mice. Based on these observations and on reports that show that the closely related Nramp2 gene is a metal ion transporter, we evaluated the effect of iron on the growth of Mycobacterium avium within macrophages as well as on the stability of Nramp1 mRNA. The addition of iron to macrophages from Bcgs mice resulted in a stimulation of mycobacterial growth. In contrast, iron increased the capacity of macrophages from Bcgr mice to control the growth of M. avium. When we treated recombinant gamma interferon (IFN-gamma)-activated macrophages with iron, we found that iron abrogated the growth inhibitory effect of IFN-gamma-activated macrophages from Bcgs mice but that it did not affect the capacity of macrophages from Bcgr mice to control microbial growth. A more detailed examination of the effect of iron on microbial growth showed that the addition of small quantities of iron to resident macrophages from Bcgr mice stimulated antimicrobial activity within a very narrow dose range. The effect of iron on the growth inhibitory activity of macrophages from Bcgr mice was abrogated by the addition of catalase or mannitol to the culture medium. These results are consistent with an Fe(II)-mediated stimulation of the Fenton/Haber-Weiss reaction and hydroxyl radical-mediated inhibition of mycobacterial growth.  (+info)

Characterisation of copper-binding to the second sub-domain of the Menkes protein ATPase (MNKr2). (2/3516)

The Menkes ATPase (MNK) has an essential role in the translocation of copper across cellular membranes. In a complementary manner, the intracellular concentration of copper regulates the activity and cellular location of the ATPase through its six homologous amino-terminal domains. The roles of the six amino-terminal domains in the activation and cellular trafficking processes are unknown. Understanding the role of these domains relies on the development of an understanding of their metal-binding properties and structural properties. The second conserved sub-domain of MNK was over-expressed, purified and its copper-binding properties characterised. Reconstitution studies demonstrate that copper binds to MNKr2 as Cu(I) with a stoichiometry of one copper per domain. This is the first direct evidence of copper-binding to the MNK amino-terminal repeats. Circular dichroism studies suggest that the binding or loss of copper to MNKr2 does not cause substantial changes to the secondary structure of the protein.  (+info)

The iron transport protein NRAMP2 is an integral membrane glycoprotein that colocalizes with transferrin in recycling endosomes. (3/3516)

The natural resistance associated macrophage protein (Nramp) gene family is composed of two members in mammals, Nramp1 and Nramp2. Nramp1 is expressed primarily in macrophages and mutations at this locus cause susceptibility to infectious diseases. Nramp2 has a much broader range of tissue expression and mutations at Nramp2 result in iron deficiency, indicating a role for Nramp2 in iron metabolism. To get further insight into the function and mechanism of action of Nramp proteins, we have generated isoform specific anti-Nramp1 and anti-Nramp2 antisera. Immunoblotting experiments indicate that Nramp2 is present in a number of cell types, including hemopoietic precursors, and is coexpressed with Nramp1 in primary macrophages and macrophage cell lines. Nramp2 is expressed as a 90-100-kD integral membrane protein extensively modified by glycosylation (>40% of molecular mass). Subcellular localization studies by immunofluorescence and confocal microscopy indicate distinct and nonoverlapping localization for Nramp1 and Nramp2. Nramp1 is expressed in the lysosomal compartment, whereas Nramp2 is not detectable in the lysosomes but is expressed primarily in recycling endosomes and also, to a lower extent, at the plasma membrane, colocalizing with transferrin. These findings suggest that Nramp2 plays a key role in the metabolism of transferrin-bound iron by transporting free Fe2+ across the endosomal membrane and into the cytoplasm.  (+info)

Genetic selection of mutations in the high affinity K+ transporter HKT1 that define functions of a loop site for reduced Na+ permeability and increased Na+ tolerance. (4/3516)

Potassium is an important macronutrient required for plant growth, whereas sodium (Na+) can be toxic at high concentrations. The wheat K+ uptake transporter HKT1 has been shown to function in yeast and oocytes as a high affinity K+-Na+ cotransporter, and as a low affinity Na+ transporter at high external Na+. A previous study showed that point mutations in HKT1, which confer enhancement of Na+ tolerance to yeast, can be isolated by genetic selection. Here we report on the isolation of mutations in new domains of HKT1 showing further large increases in Na+ tolerance. By selection in a Na+ ATPase deletion mutant of yeast that shows a high Na+ sensitivity, new HKT1 mutants at positions Gln-270 and Asn-365 were isolated. Several independent mutations were isolated at the Asn-365 site. N365S dramatically increased Na+ tolerance in yeast compared with all other HKT1 mutants. Cation uptake experiments in yeast and biophysical characterization in Xenopus oocytes showed that the mechanisms underlying the Na+ tolerance conferred by the N365S mutant were: reduced inhibition of high affinity Rb+ (K+) uptake at high Na+ concentrations, reduced low affinity Na+ uptake, and reduced Na+ to K+ content ratios in yeast. In addition, the N365S mutant could be clearly distinguished from less Na+-tolerant HKT1 mutants by a markedly decreased relative permeability for Na+ at high Na+ concentrations. The new mutations contribute to the identification of new functional domains and an amino acid in a loop domain that is involved in cation specificity of a plant high affinity K+ transporter and will be valuable for molecular analyses of Na+ transport mechanisms and stress in plants.  (+info)

Overexpression of a novel Arabidopsis gene related to putative zinc-transporter genes from animals can lead to enhanced zinc resistance and accumulation. (5/3516)

We describe the isolation of an Arabidopsis gene that is closely related to the animal ZnT genes (Zn transporter). The protein encoded by the ZAT (Zn transporter of Arabidopsis thaliana) gene has 398 amino acid residues and is predicted to have six membrane-spanning domains. To obtain evidence for the postulated function of the Arabidopsis gene, transgenic plants with the ZAT coding sequence under control of the cauliflower mosaic virus 35S promoter were analyzed. Plants obtained with ZAT in the sense orientation exhibited enhanced Zn resistance and strongly increased Zn content in the roots under high Zn exposure. Antisense mRNA-producing plants were viable, with a wild-type level of Zn resistance and content, like plants expressing a truncated coding sequence lacking the C-terminal cytoplasmic domain of the protein. The availability of ZAT can lead to a better understanding of the mechanism of Zn homeostasis and resistance in plants.  (+info)

Ion channels: structure of a molecular brake. (6/3516)

Cloning and characterization of the transport modifier RS1 from rabbit which was previously assumed to be specific for Na+-D-glucose cotransport. (7/3516)

Previously we cloned membrane associated polypeptides from pig and man (pRS1, hRS1) which altered rate and glucose dependence of Na+-d-glucose cotransport expressed by SGLT1 from rabbit and man. This paper describes the cloning of a related cDNA sequence from rabbit intestine (rbRS1) which encodes a gene product with about 65% amino acid identity to pRS1 and hRS1. Hybridization of endonuclease-restricted genomic DNA with cDNA fragments of rbRS1 showed that there is only one gene with similarity to rbRS1 in rabbit, and genomic PCR amplifications revealed that the rbRS1 gene is intronless. Comparing the transcription of rbRS1 and rbSGLT1 in various tissues and cell types, different mRNA patterns were obtained for both genes. In Xenopus oocytes the Vmax of expressed Na+-d-glucose cotransport was increased or decreased when rbRS1 was coexpressed with rbSGLT1 or hSGLT1, respectively. After coexpression with hSGLT1 the glucose dependence of the expressed transport was changed. By coexpression of rbRS1 with the human organic cation transporter hOCT2 the expressed cation uptake was not altered; however, the expressed cation uptake was drastically decreased when hRS1 was coexpressed with hOCT2. The data show that RS1 can modulate the function of transporters with non-homologous primary structures.  (+info)

Mechanism of increased iron absorption in murine model of hereditary hemochromatosis: increased duodenal expression of the iron transporter DMT1. (8/3516)

Hereditary hemochromatosis (HH) is a common autosomal recessive disorder characterized by tissue iron deposition secondary to excessive dietary iron absorption. We recently reported that HFE, the protein defective in HH, was physically associated with the transferrin receptor (TfR) in duodenal crypt cells and proposed that mutations in HFE attenuate the uptake of transferrin-bound iron from plasma by duodenal crypt cells, leading to up-regulation of transporters for dietary iron. Here, we tested the hypothesis that HFE-/- mice have increased duodenal expression of the divalent metal transporter (DMT1). By 4 weeks of age, the HFE-/- mice demonstrated iron loading when compared with HFE+/+ littermates, with elevated transferrin saturations (68.4% vs. 49.8%) and elevated liver iron concentrations (985 micrograms vs. 381 micrograms). By using Northern blot analyses, we quantitated duodenal expression of both classes of DMT1 transcripts: one containing an iron responsive element (IRE), called DMT1(IRE), and one containing no IRE, called DMT1(non-IRE). The positive control for DMT1 up-regulation was a murine model of dietary iron deficiency that demonstrated greatly increased levels of duodenal DMT1(IRE) mRNA. HFE-/- mice also demonstrated an increase in duodenal DMT1(IRE) mRNA (average 7.7-fold), despite their elevated transferrin saturation and hepatic iron content. Duodenal expression of DMT1(non-IRE) was not increased, nor was hepatic expression of DMT1 increased. These data support the model for HH in which HFE mutations lead to inappropriately low crypt cell iron, with resultant stabilization of DMT1(IRE) mRNA, up-regulation of DMT1, and increased absorption of dietary iron.  (+info)

Legumes are key to world agriculture (Graham and Vance, 2003). They are the main protein source in many areas of the world and, because of SNF, a viable alternative to the use of nitrogen fertilizers in agriculture (Smil, 1999). As in any plant, iron uptake and systemic distribution is critical in legumes. Like in other nongraminaceous plants, in legumes, iron uptake from soil follows what is known as Strategy I, i.e. Fe3+ solubility is increased by acidification of the surrounding soil and then Fe3+ is reduced by a ferroreductase to Fe2+, which is imported into plants via specific transporters in the root epidermis (Andaluz et al., 2009). Once inside the plant, iron is used in legumes as in other plants, with one exception; in addition to the shoot, there is an extra iron sink during vegetative stages of growth, namely the root nodule (Tang et al., 1990).. Nodulation requires relatively large amounts of iron to synthesize the key enzymes involved in SNF (Brear et al., 2013; González-Guerrero ...

High-affinity K+ uptake in plants plays a crucial role in K+ nutrition and different systems have been postulated to contribute to the high-affinity K+ uptake. The results presented here with pepper (Capsicum annum) demonstrate that a HAK1-type transporter greatly contributes to the high-affinity K+ uptake observed in roots. Pepper plants starved of K+ for 3 d showed high-affinity K+ uptake (K m of 6 mgrM K+) that was very sensitive to NH and their roots expressed a high-affinity K+ transporter, CaHAK1, which clusters in group I of the KT/HAK/KUP family of transporters. When expressed in yeast (Saccharomyces cerevisiae), CaHAK1 mediated high-affinity K+ and Rb+ uptake with K m values of 3.3 and 1.9 mgr M, respectively. Rb+ uptake was competitively inhibited by micromolar concentrations of NH and Cs+, and by millimolar concentrations of Na+ ...

Distribution of ferroportin1 protein in different regions of developing rat brain | PolyU Institutional Research Archive  Distribution of ferroportin1 protein in different regions of developing rat brain | PolyU Institutional Research Archive
Ferroportin1 is a newly discovered transmembrane iron export protein. It plays a key role in Fe2+transport across the basal membrane of enterocytes in the gut. It has been suggested that this protein might have the same role in Fe2+transport across the abluminal membrane of the blood-brain barrier as it works in enterocytes. However, the presence of ferroportin1 in the brain has not been well determined. In the present study, we investigated expression of ferroportin1 protein in different brain regions, including cortex, hippocampus, striatum and substantia nigra, in developing male Sprague-Dawley rats. The results provided direct evidence for the existence of ferroportin1 protein in the rat brain. All brain areas examined have the ability to synthesize ferroportin1 protein. The findings also showed that age has a significant effect on the expression of ferroportin1 protein in the cortex, hippocampus, striatum and substantia nigra of the rat brain ...

Earlier studies have indicated that sensitivity to the Pt drugs can be regulated by the Cu influx transporter CTR1 (3 , 4) and the Cu exporter ATP7B (5 , 10) . The results reported here indicate that another Cu transporter, ATP7A, is also capable of modulating sensitivity to this class of drugs and that this effect is observable in ovarian cancer cells. Furthermore, the results document that even a quite modest change in ATP7A level is pharmacodynamically significant. These findings provide additional support for the concept that the Cu transporters are important to the pharmacodynamics of the Pt-containing drugs and specifically identify small changes in ATP7A expression as being of relevance in ovarian cancer.. Western blot analysis of ovarian carcinoma cell lines selected in vitro for acquired resistance to DDP (10) and immunohistochemical analysis of ovarian carcinoma samples from patients failing DDP and/or CBDCA-containing primary chemotherapy (20) have demonstrated only modest changes in ...

Rhesus Proteins Transport Ions, not Gas  Rhesus Proteins Transport Ions, not Gas
The results can, in a large part, be transferred to the Rhesus proteins from mammals," says Andrade as Amt proteins bear a close resemblance to the Rhesus proteins found in humans. They are produced in the blood, in the kidney, and in the liver, where they regulate the intake of ammonium and thus the bodys pH.. The researchers tested three Amt proteins that are present in the bacteria and also determined the speed with which they allow ammonium to pass through the membrane. "In the future, we want to modify individual components of the transporter to improve our understanding of the exact molecular details involved" explains Andrade.. The scientific debate on Amt/Rh proteins stems from the difficulty of distinguishing between ammonia and ammonium in measurements, as the two molecules are transformed into each other in a continuous state of balance with protons. "Our in vitro method gives us a level of precision that finally allows us to draw valid conclusions concerning the transport process," ...

Brucella abortus is a Gram-negative bacterium that causes abortion and infertility in food animals and a chronic debilitating febrile disease in humans known as brucellosis. As with all pathogenic bacteria, the Brucella spp. require sufficient metal nutrition during the course of an infection. Host-mediated metal withdrawal defenses actively restrict the bioavailability of metals which requires invading bacteria to employ high affinity metal acquisition systems to overcome these metal-limiting conditions. While obtaining sufficient metals during host infection is critical to the survival of these bacteria, avoiding metal toxicity is equally important. Excess accumulation of one metal relative to others can lead to protein mis-metallation when surplus metal ions outcompete other metal species for their native binding sites. To prevent metal toxicity, bacteria respond to high intracellular metal concentrations by means of metal-responsive transcriptional regulators that downregulate metal import ...

AU - Savaraj, Niramol. AU - Kuo, Macus Tien. PY - 2014/1/14. Y1 - 2014/1/14. N2 - Platinum-based antitumor agents have been the mainstay in cancer chemotherapy for many human malignancies. Drug resistance is an important obstacle to achieving the maximal therapeutic efficacy of these drugs. Understanding how platinum drugs enter cells is of great importance in improving therapeutic efficacy. It has been demonstrated that human high-affinity copper transporter 1 (hCtr1) is involved in transporting cisplatin into cells to elicit cytotoxic effects, although other mechanisms may exist. In this communication, we demonstrate that cisplatin transcriptionally induces the expression of hCtr1 in time- and concentration-dependent manners. Cisplatin functions as a competitor for hCtr1-mediated copper transport, resulting in reduced ...

Cation diffusion facilitator (CDF) proteins are a conserved family of transmembrane transporters that ensure cellular homeostasis of divalent transition metal cations. Metal cations bind to CDF proteins cytoplasmic C-terminal domain (CTD), leading to closure from its apo open V-shaped dimer to a tighter packed structure, followed by a conformational change of the transmembrane domain thus enabling transport of the metal cation. By implementing a comprehensive range of biochemical and biophysical methods, we studied the molecular mechanism of metal binding to the magnetotactic bacterial CDF protein MamM CTD. Our results reveal that the CTD is rather dynamic in its apo form, and that two dependent metal binding sites, a single central binding site and two symmetrical, peripheral sites, are available for metal binding. However, only cation binding to the peripheral sites leads to conformational changes that lock the protein in a compact state. Thus, this work reveals how metal binding is ...

Copper transport protein and inflammatory angiogenesis - Augusta University Research Profiles  Copper transport protein and inflammatory angiogenesis - Augusta University Research Profiles
DESCRIPTION (provided by applicant): The overall aim of this grant is to elucidate the novel linkage between copper transport protein Antioxidant1 (Atox1) and NADPH oxidase involved in inflammatory angiogenesis. Ischemic disease is a leading cause of morbidity and mortality in worldwide. Neovascularization is an important repair process in response to ischemia, which depends on angiogenesis, inflammation and reactive oxygen species (ROS). Copper (Cu), an essential micronutrient, is involved in physiological repair processes such as wound healing and angiogenesis as well as in various pathophysiologies including tumor growth, atherosclerosis and inflammatory diseases. Since excess Cu is toxic, bioavailability of intracellular Cu is tightly controlled by Cu transport proteins such as Cu chaperone Atox1. Our laboratories provided the first evidence that Atox1 functions as a Cu-dependent transcription factor to regulate Cu-induced cell growth. Furthermore, we are one of the first to demonstrate that ...

This gene encodes a member of the SLC39 family of solute-carrier genes, which show structural characteristics of zinc transporters. The encoded protein is glycosylated and found in the plasma membrane and mitochondria, and functions in the cellular import of zinc at the onset of inflammation. It is also thought to be the primary transporter of the toxic cation cadmium, which is found in cigarette smoke. Multiple transcript variants encoding different isoforms have been found for this gene. Additional alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known. [provided by RefSeq, Oct 2008 ...

Reduced sensitivity of the ferroportin Q248H mutant to physiological concentrations of hepcidin | Haematologica  Reduced sensitivity of the ferroportin Q248H mutant to physiological concentrations of hepcidin | Haematologica
Our present findings suggest that the ferroportin Q248H mutant is resistant to physiological concentrations of hepcidin (0.01-0.03 μM),12-15 despite bioinformatic predictions suggesting that it is a neutral polymorphism. We observed this with both human myc-tagged ferroportin and ferroportin fused to EGFP that were expressed in 293T cells treated with hepcidin and detected by immunoblotting or EGFP fluorescence. These observations were further supported by analysis of intracellular ferritin that reflects the amount of iron stored within the cells. The hepcidin-mediated increase of ferritin was less pronounced in 293T cells that expressed ferroportin Q248H compared to cells that expressed WT ferroportin. Analysis of ferritin levels in primary macrophages differentiated from primary human monocytes after incubation with iron and a short exposure to hepcidin showed a dose-dependent association with ferroportin genotype. No increase in macrophage ferritin was observed with homozygous ferroportin ...

Polymorphisms in the Gene That Encodes the Iron Transport Protein Ferroportin 1 Influence Susceptibility to Tuberculosis  Polymorphisms in the Gene That Encodes the Iron Transport Protein Ferroportin 1 Influence Susceptibility to Tuberculosis
Background: We studied the association between iron intake and polymorphisms in the iron transporter gene, SLC40A1, and the risk of tuberculosis. Methods: We compared iron intake, the frequency of SLC40A1 mutations, and interactions between these variables among 98 TB patients and 125 controls in Kwazulu-Natal, South Africa. Results: Four SLC40A1 SNPs were associated with an increased risk of tuberculosis and one with reduced risk. We also found a gene-environment interaction for four non-exonic SNPs and iron intake. Conclusions: This pilot study demonstrated an association between polymorphisms in SLC40A1 and tuberculosis and provided evidence for an interaction between dietary iron and SLC40A1 ...

Unusual Ammonium Transporters - Transport across and into membranes  Unusual Ammonium Transporters - Transport across and into membranes
Ammonium transport (Amt) proteins are ubiquitous integral membrane proteins that transport NH4+ across cell membranes. Amt proteins involved in the uptake of NH4+ as direct N-source for biosynthesis are present in prokaryotes, archaea and plants [1]. In mammals, Rhesus proteins are the Amt homologs and their presence in erythrocyte, kidney and liver cell membranes can be directly related to NH3/NH4+ detoxification and pH homeostasis processes [2]. Long recognized for their immunogenic characteristics and involvement in hemolytic diseases of infants, a number of genetic diseases have been associated with the inability to correctly express Rh proteins [2,3]. Understanding the molecular details of transport and regulation of Amt proteins is therefore highly relevant to help treat and solve many human Rh-related diseases.. A significant amount of our research has focused on the archaea homologs, in particular on the Af-Amt1 protein from Archaeoglobus fulgidus. We have solved the crystal structures ...

ZIP13 Antibody | Abbiotec  ZIP13 Antibody | Abbiotec
The zinc transporter ZIP13, also known as SLC39A13, is a member of a family of divalent ion transporters. Zinc is an essential ion for cells and plays significant roles in the growth, development, and differentiation. The zinc transporter family is divided into four subfamilies (I, II, LIV-1 and gufA). ZIP13 is a multipass membrane protein that belongs to the ZIP transporter subfamily LIV-1. Mutations in ZIP13 have recently been shown to cause a spondylocheiro dysplastic form of Ehlers-Danlos syndrome (SCD-EDS), a generalized skeletal dysplasia involving mainly the spine with clinical abnormalities of the hands in addition to EDS-like features. Other experiments have shown that ZIP13 is required for proper connective tissue development and is involved in BMP/TGF- signaling pathways ...

Role of proteolysis in copper homoeostasis | Biochemical Society Transactions  Role of proteolysis in copper homoeostasis | Biochemical Society Transactions
The cop operon of Enterococcus hirae controls cytoplasmic copper levels. It encodes two copper ATPases, a repressor, and the CopZ metallo-chaperone. Transcription of these genes is induced by copper. However, at higher copper concentrations, CopZ is degraded by a copper-activated proteolytic activity. This specific proteolysis of CopZ can also be demonstrated in vitro with E. hirae extracts. Growth of the cells in copper increases the copper-inducible proteolytic activity in extracts. Zymography reveals the presence of a copper-dependent protease in crude cell lysates. Copper-stimulated proteolysis of CopZ appears to play an important role in copper homoeostasis by E. hirae. ...

Author Summary Loss-of-function of the zinc transporter ZIP4 in the mouse intestine mimics the lethal human disease acrodermatitis enteropathica. This is a rare disease in humans that is not well understood. Our studies demonstrate the paramount importance of ZIP4 in the intestine in this disease and reveal that a root cause of lethality is disruption of the intestine stem cell niche and impaired function of the small intestine. This, in turn, leads to dramatic weight loss and death unless treated with exogenous zinc.

Menkes disease and occipital horn syndrome are two forms of copper deficiency that must be diagnosed and treated very early in life to prevent serious developmental problems. However, these and other forms of copper deficiency are not very well understood, and further research is needed to determine whether certain treatments are useful in treating copper deficiency. One such treatment is copper histidine, a copper replacement that can be injected directly into the body to avoid absorption through the gastrointestinal tract. This study will investigate the effectiveness, side effects, and dosage of copper histidine treatment for patients with copper deficiency. It will also collect medical history information from patients to allow researchers to study possible genetic and nongenetic origins of copper deficiency.. This study will include 100 subjects, all of whom will be children and adults who have been diagnosed with Menkes disease, occipital horn syndrome, or other unexplained copper ...

Endothelial dysfunction, in part caused by oxidative inactivation of nitric oxide (NO•) by excess level of O2•-, contributes to various cardiovascular diseases including diabetes (DM). Extracellular superoxide dismutase (ecSOD), a secretory Cu enzyme, is the major antioxidant enzyme against O2•- in the vascular extracellular space. However, role of endogenous ecSOD in diabetic vessels remains unclear. Here we show that specific activity of ecSOD, but not cytosolic Cu/Zn SOD, is decreased by 35% in aortas of streptozotocin (STZ)-induced DM mice. This is associated with significantly increased L-NAME-sensitive O2•- production (P,0.05) and increased 3-nitrotyrosine (3-NT) level, a marker of ONOO-, implicating eNOS uncoupling. Functionally, acetylcholine-induced NO-mediated vasorelaxation is impaired (P,0.05) in mesenteric arteries of DM, which is rescued by SOD mimetic tempol or adenovirus mediated gene transfer of ecSOD. Importantly, supplementation of catalytic cofactor copper (Cu) ...

JCI - Hepatic metal ion transporter ZIP8 regulates manganese homeostasis and manganese-dependent enzyme activity  JCI - Hepatic metal ion transporter ZIP8 regulates manganese homeostasis and manganese-dependent enzyme activity
Animals. Mice harboring the Slc39a8 conditional knockout allele C57BL/6-Slc39a8tm1.1 mrl and the constitutive knockout allele C57BL/6-Slc39a8tm1.2 mrl were provided by Merck. Details on the design of the ZIP8 mice can be found on the Taconic website (http://www.taconic.com/mouse-model/slc39a8-cko-11296 and http://www.taconic.com/mouse-model/slc39a8-ko). Briefly, the Slc39a8tm1.1 mrl allele has exon 3 flanked by loxP sites. The Slc39a8tm1.2 mrl allele was generated by Cre-mediated loxP site recombination, resulting in removal of the third exon of Slc39a8. The Slc39a8tm1.2 mrl allele deleted the N-terminal part of the ZIP domain and the first 2 transmembrane domains and generated a premature stop codon predicted to result in a protein null mouse. Alb-Cre mice, which express Cre under the control of the liver-specific albumin promoter beginning from P7, were obtained from The Jackson Laboratory (stock number 003574) and were crossed with C57BL/6-Slc39a8tm1.1 mrl mice to generate Slc39a8 ...

UPENN Biomedical Graduate Studies | Donita C. Brady  UPENN Biomedical Graduate Studies | Donita C. Brady
For example, while investigating pharmacologically accessible signaling pathways downstream of oncogenic RAS, we recently demonstrated that genetic ablation of the high affinity Cu transporter CTR1 responsible for Cu uptake resulted in decreased RAF-MEK-ERK signaling through loss of the interaction between Cu and the kinases MEK1/2. This is the first example demonstrating Cu directly regulates the activity of a mammalian kinase, and hence has opened up a new way to explore how metals interact with signaling pathways. Capitalizing on the dependence of oncogenic mutations in the RAS effector protein BRAF for MEK1/2 activity, a multifaceted approach was used to examine this new signaling mechanism in the context of BRAF mutation-positive cancer. Specifically, we reported that decreasing the levels of CTR1, or introducing mutations in MEK1 that disrupt Cu binding, decreased BRAFV600E-driven signaling and tumorigenesis. Furthermore, Cu chelators used in the treatment of Wilson disease decreased the ...

Wilson (House episode) - Wikipedia  Wilson (House episode) - Wikipedia
House wakes Wilson from sleep at 6:30 am by playing his guitar and singing "Faith" by George Michael. House is curious as to why Wilson is not getting ready for work, and Wilson explains that he is not going to work - he is taking a day off, and going hunting. He returns to bed but is followed by House who states that the person Wilson is going hunting with is a "self-important jerk" who does not even know his name. Wilson ignores him and goes back to sleep.. The hunting trip is with Tucker, a former oncology patient who credits Wilson with saving his life 5 years prior. Tucker wants to reward "Jim" in various ways (such as taking him on this hunting trip) for saving his life. They follow a ritual of sticking an empty chemotherapy bag into a tree, Wilson labeling it with the number of years Tucker has been free of cancer and Tucker shooting the bag.

The discovery that hCtr1 can transport platinum-based antitumor agents (Ishida et al., 2002) underscores the importance of this metal transporter in cancer chemotherapy. In this communication, we report that overexpression of GSH sensitizes cancer cells to the treatment of CDDP by up-regulating hCtr1 expression. Although the rates of copper transport were also elevated in these hCtr1-overproducing cells, no enhanced sensitization to copper toxicity was found in these cells. These results suggest that the imported copper was nontoxic, most likely because of detoxification either by direct metallation of GSH or by GSH-mediated sequestration of undefined compartments. Consistent with this notion, the bioavailable copper was reduced in these cells.. Our results showed, for the first time, that GSH can interfere with intracellular copper physiology by depleting the pool of bioavailable copper (Fig. 7), leading to the increased import of CDDP, which enhances the cell-killing effects of CDDP. This ...

Copper (Cu) is an essential metal required for activity of a number of redox active enzymes that participate in critical cellular pathways such as metabolism and cell signaling. Because it is also a toxic metal, Cu must be tightly controlled by a series of transporters and chaperone proteins that regulate Cu homeostasis. The critical nature of Cu is highlighted by the fact that mutations in Cu homeostasis genes cause pathologic conditions such as Menkes and Wilson diseases. While Cu homeostasis in highly affected tissues like the liver and brain is well understood, no study has probed the role of Cu in development of skeletal muscle, another tissue that often shows pathology in these conditions ...

Rhesus (Rh) type C glycoprotein NH3/NH4+ transporter, RhCG (also called tumor-related protein DRC2) (Bakouh et al., 2004; Worrell et al., 2007). Zidi-Yahiaoui et al. (2009) have described characteristics of the pore/vestibule. The structure is known to 2.1 Å resolution (Gruswitz et al., 2010). Each monomer contains 12 transmembrane helices, one more than in the bacterial homologs. Reconstituted into proteoliposomes, RhCG conducts NH3 to raise the internal pH. Models of the erythrocyte Rh complex based on the RhCG structure suggest that the erythrocytic Rh complex is composed of stochastically assembled heterotrimers of RhAG, RhD, and RhCE (Gruswitz et al., 2010 ...

Disease-causing point-mutations in metal-binding domains of Wilson disease protein decrease stability and increase structural...  Disease-causing point-mutations in metal-binding domains of Wilson disease protein decrease stability and increase structural...
After cellular uptake, Copper (Cu) ions are transferred from the chaperone Atox1 to the Wilson disease protein (ATP7B) for incorporation into Cu-dependent enzymes in the secretory pathway. Human ATP7B is a large multi-domain membrane-spanning protein which, in contrast to homologues in other organisms, has six similar cytoplasmic metal-binding domains (MBDs). The reason for multiple MBDs is proposed to be indirect modulation of enzymatic activity and it is thus intriguing that point mutations in MBDs can promote Wilson disease. We here investigated, in vitro and in silico, the biophysical consequences of clinically-observed Wilson disease mutations, G85V in MBD1 and G591D in MBD6, incorporated in domain 4. Because G85 and G591 correspond to a conserved Gly found in all MBDs, we introduced the mutations in the well-characterized MBD4. We found the mutations to dramatically reduce the MBD4 thermal stability, shifting the midpoint temperature of unfolding by more than 20 A degrees C. In contrast to ...

JCI - Hemojuvelin is essential for dietary iron sensing, and its mutation leads to severe iron overload  JCI - Hemojuvelin is essential for dietary iron sensing, and its mutation leads to severe iron overload
Iron homeostasis plays a critical role in many physiological processes, notably synthesis of heme proteins. Dietary iron sensing and inflammation converge in the control of iron absorption and retention by regulating the expression of hepcidin, a regulator of the iron exporter ferroportin. Human mutations in the glycosylphosphatidylinositol-anchored protein hemojuvelin (HJV; also known as RGMc and HFE2) cause juvenile hemochromatosis, a severe iron overload disease, but the way in which HJV intersects with the iron regulatory network has been unclear. Here we show that, within the liver, mouse Hjv is selectively expressed by periportal hepatocytes and also that Hjv-mutant mice exhibit iron overload as well as a dramatic decrease in hepcidin expression. Our findings define a key role for Hjv in dietary iron sensing and also reveal that cytokine-induced inflammation regulates hepcidin expression through an Hjv-independent pathway.. ...

search
  • Phagosomes from Nramp1(+/+) mice extrude Mn(2+) faster than their Nramp(-/-) counterparts.The difference in the rate of transport is eliminated when acidification of the phagosomal lumen is dissipated, suggesting that divalent metal transport through Nramp1 is H(+) dependent.Such cations are likely essential for microbial function and their removal from the phagosomal microenvironment impairs pathogenesis, resulting in enhanced bacteriostasis or bactericidal activity. (nih.gov)
  • The difference in the rate of transport is eliminated when acidification of the phagosomal lumen is dissipated, suggesting that divalent metal transport through Nramp1 is H(+) dependent. (nih.gov)
