    Secondary acrodermatitis enteropathica-like lesions in a child with newly diagnosed coeliac disease.
    Paediatr Int Child Health 2016 Feb 26;36(1):72-5. Epub 2014 Dec 26.
    Department of Paediatrics, SCB Medical College , Cuttack.
    Zinc deficiency in patients with coeliac disease (CD) may result either from cumulative loss of insoluble zinc complexes or impaired zinc absorption because of damaged intestinal epithelial cell membrane. Zinc deficiency in CD is mild to moderate, though severe deficiency can occur in refractory or chronic CD cases with poor response to gluten-free diet (GFD). A boy aged 19 months presented with persistent diarrhoea, was diagnosed with CD, and developed severe zinc deficiency with acrodermatitis enteropathica-like disease while on GFD and zinc supplementation.

    Overview of Inherited Zinc Deficiency in Infants and Children.
    J Nutr Sci Vitaminol (Tokyo) 2015 ;61 Suppl:S44-6
    Division of Integrated Life Science, Graduate School of Biostudies, Kyoto University.
    Zinc nutrition is of special practical importance in infants and children. Poor zinc absorption causes zinc deficiency, which leads to a broad range of consequences such as alopecia, diarrhea, skin lesions, taste disorders, loss of appetite, impaired immune function and neuropsychiatric changes and growth retardation, thus potentially threatening life in infants and children. In addition to dietary zinc deficiency, inherited zinc deficiency, which rarely occurs, is found during the infant stage and early childhood. Read More

    A role for dZIP89B in Drosophila dietary zinc uptake reveals additional complexity in the zinc absorption process.
    Int J Biochem Cell Biol 2015 Dec 13;69:11-9. Epub 2015 Oct 13.
    School of Biological Sciences, Monash University, Victoria, Australia. Electronic address:
    Dietary zinc is the principal source of zinc in eukaryotes, with its uptake and distribution controlled by a complex network of numerous membrane-spanning transport proteins. Dietary absorption is achieved by members of the SLC39A (ZIP) gene family, which encode proteins that are generally responsible for the movement of zinc into the cytosol. ZIP4 is thought to be the primary mammalian zinc uptake gene in the small intestine, with mutations in this gene causing the zinc deficiency disease Acrodermatitis enteropathica. Read More

    Soybean extracts increase cell surface ZIP4 abundance and cellular zinc levels: a potential novel strategy to enhance zinc absorption by ZIP4 targeting.
    Biochem J 2015 Dec 18;472(2):183-93. Epub 2015 Sep 18.
    Division of Integrated Life Science, Graduate School of Biostudies, Kyoto University, Kyoto, Japan
    Dietary zinc deficiency puts human health at risk, so we explored strategies for enhancing zinc absorption. In the small intestine, the zinc transporter ZIP4 functions as an essential component of zinc absorption. Overexpression of ZIP4 protein increases zinc uptake and thereby cellular zinc levels, suggesting that food components with the ability to increase ZIP4 could potentially enhance zinc absorption via the intestine.

    Vimentin filament organization and stress sensing depend on its single cysteine residue and zinc binding.
    Nat Commun 2015 Jun 2;6:7287. Epub 2015 Jun 2.
    Department of Chemical and Physical Biology, Centro de Investigaciones Biológicas, Consejo Superior de Investigaciones Científicas (C.S.I.C.), Ramiro de Maeztu, 9, 28040 Madrid, Spain.
    The vimentin filament network plays a key role in cell architecture and signalling, as well as in epithelial-mesenchymal transition. Vimentin C328 is targeted by various oxidative modifications, but its role in vimentin organization is not known. Here we show that C328 is essential for vimentin network reorganization in response to oxidants and electrophiles, and is required for optimal vimentin performance in network expansion, lysosomal distribution and aggresome formation.
