ZnT7 (Slc30a7) is a widely expressed zinc transporter involved in sequestration of zinc into the Golgi apparatus and vesicular compartments. Znt7-knockout (KO) mice are mildly zinc deficient and lean. Despite their lean phenotype, adult male Znt7-KO mice are prone to insulin resistance. We hypothesized that fat partitioning from adipose to non-adipose tissues causes insulin resistance in Znt7-KO mice. Here, we used biological and biochemical methods including fatty acid and oxylipin profiling, electron microscopy, immunohistochemistry, quantitative RT-PCR, and Western blot analysis to identify the underlying mechanism of insulin resistance in Znt7-KO mice...

Dominant mutations in the gene encoding copper and zinc-binding superoxide dismutase (SOD1) cause amyotrophic lateral sclerosis (ALS). Abnormal accumulation of misfolded SOD1 proteins in spinal motoneurons is a major pathological hallmark in SOD1-related ALS. Dissociation of copper and/or zinc ions from SOD1 has been shown to trigger the protein aggregation/oligomerization in vitro, but the pathological contribution of such metal dissociation to the SOD1 misfolding still remains obscure. Here, we tested the relevance of the metal-deficient SOD1 in the misfolding in vivo by developing a novel antibody (anti-apoSOD), which exclusively recognized mutant SOD1 deficient in metal ions at its copper-binding site...

The kidney ultrafiltration barrier is formed of endothelial cells, the glomerular basement membrane and podocytes. Podocytes have a central role in normal physiology and disease pathogenesis of the glomerulus. Signaling through epidermal growth factor receptor (EGFR) in podocytes mediates development of many glomerular disease processes. In this work, we have identified zinc finger FYVE-type containing 28 (ZFYVE28) as a novel highly podocyte-enriched gene. We localize ZFYVE28 in podocyte foot processes in adult kidney...

This study provides the dietary intakes of six trace elements (cadmium, chromium, copper, manganese, selenium and zinc), generally characterized by both nutritional and toxicological features depending on their exposure. Being diet the most relevant source of exposure to trace elements in non-professionally exposed subjects, we measured content of these trace elements in foods composing the typical Italian diet using inductively coupled plasma-mass spectrometry, and assessing dietary habits using a validated semi-quantitative food frequency questionnaire we eventually estimated dietary daily intake of trace elements in a Northern Italian community...

γδ T cells, known to be an important source of innate IL-17 in mice, provide critical contributions to host immune responses. Development and function of γδ T cells are directed by networks of diverse transcription factors (TFs). Here, we examine the role of the zinc finger TFs, Kruppel-like factor 10 (KLF10), in the regulation of IL-17-committed CD27- γδ T (γδ27- -17) cells. We found selective augmentation of Vγ4+ γδ27- cells with higher IL-17 production in KLF10-deficient mice. Surprisingly, KLF10-deficient CD127hi Vγ4+ γδ27- -17 cells expressed higher levels of CD5 than their wild-type counterparts, with hyper-responsiveness to cytokine, but not T-cell receptor, stimuli...

Heterozygous mutations in MECOM (MDS1 and EVI1 complex locus) have been reported to be causative of a rare association of congenital amegakaryocytic thrombocytopenia and radioulnar synostosis. Here we report on 12 patients with congenital hypomegakaryocytic thrombocytopenia caused by MECOM mutations (including 10 novel mutations). The mutations affected different functional domains of the EVI1 protein. The spectrum of phenotypes was much broader than initially reported for the first 3 patients; we found familial as well as sporadic cases, and the clinical spectrum ranged from isolated radioulnar synostosis with no or mild hematological involvement to severe bone marrow failure without obvious skeletal abnormality...

Ventricular myocardial development is a well-orchestrated process involving different cardiac structures, multiple signal pathways, and myriad proteins. Dysregulation of this important developmental event can result in cardiomyopathies, such as left ventricle non-compaction, which affect the pediatric population and the adults. Human and mouse studies have shed light upon the etiology of some cardiomyopathy cases and highlighted the contribution of both genetic and environmental factors. However, the regulation of ventricular myocardial development remains incompletely understood...

Zinc is an essential trace element that is required for the function of a large number of proteins. As these zinc-binding proteins are found within the cytosol and organelles, all eukaryotes require mechanisms to ensure that zinc is delivered to organelles, even under conditions of zinc deficiency. Although many zinc transporters belonging to the Cation Diffusion Facilitator (CDF) families have well characterized roles in transporting zinc into the lumens of intracellular compartments, relatively little is known about the mechanisms that maintain organelle zinc homeostasis...

Micronutrient malnutrition during intrauterine and postnatal growth may program cardiovascular diseases in adulthood. We examined whether moderate zinc restriction in male and female rats throughout fetal life, lactation and/or postweaning growth induces alterations that can predispose to the onset of vascular dysfunction in adulthood. Female Wistar rats were fed low- or control zinc diets from pregnancy to offspring weaning. After weaning, offspring were fed either a low- or a control zinc diet until 81 days...

BACKGROUND: Micronutrient deficiencies are major concerns after bariatric surgery, although these conditions often go undiagnosed pre-surgery. OBJECTIVE: To assess pre-surgery micronutrient status of an Iranian population of morbidly obese candidates of bariatric surgery in a cross-sectional study. METHODS: A cross-sectional analysis of 2008 candidates for bariatric surgery, aged 15-65 years, with either body mass index (BMI) ≥ 40 kg/m2 or 30 < BMI < 35 kg/m2 with a medical comorbidity was conducted...

Sporadic Alzheimer's disease (AD) is a neurodegenerative disorder that causes the most prevalent form of age-related dementia but its pathogenesis remains obscure. Altered regulation of metals, particularly pan-cerebral copper deficiency, and more regionally-localized perturbation of other metals, are prominent in AD brain although data on how these CNS perturbations are reflected in the peripheral bloodstream are inconsistent to date. To assess the potential use of metal dysregulation to generate biomarkers in AD, we performed a case-control study of seven essential metals and selenium, measured by inductively coupled plasma mass-spectrometry, in samples from AD and matched control cases...

Vegetarianism provides a catchall term for a variety of diets that exclude the consumption of some or all animal products. Contrary to popular claims, appropriately designed and managed vegetarian diets contain foods nutritionally sufficient for health, well-being, and physical performance. Vegetarian dancers can meet their protein needs from primarily or exclusively (vegan) plant-based sources when a variety of these foods are consumed daily and energy intake is adequate. However, the quality and timing of dietary intake is of key importance to meet the physical demands typical of high intensity, intermittent types of dance styles...

Obesity is associated with adipose tissue inflammation that contributes to insulin resistance. Zinc Finger Protein 36 (Zfp36) is an mRNA-binding protein that reduces inflammation by binding to cytokine transcripts and promoting their degradation. We hypothesized that myeloid-specific deficiency of Zfp36 would lead to increased adipose tissue inflammation and reduced insulin sensitivity in diet-induced obese mice. As expected, wild type (Control) mice became obese and diabetic on a high-fat diet and obese mice with myeloid-specific loss of Zfp36 (KO) demonstrated increased adipose tissue and liver cytokine mRNA expression compared to Control mice...

The effects of essential (I, Se, and Zn) and toxic (Pb and Cd) trace elements on the thyroid function were studied experimentally. The protective effects of iodine, zinc, and selenium on thyroid tissue and antithyroid effects of toxic trace elements promoting a decrease in the levels of thyroid hormones (T3 , T4 ) and imbalance of pituitary hormones (TSH) were detected. Addition of toxic trace elements to the ration of experimental rats led to their accumulation in the thyroid (0.051 μg/g Pb and 0.190 μg/g Cd)...

Inadequate dietary zinc intake is wide-spread in the world's population. Despite the clinical significance of zinc deficiency there is no established method or biomarker to reliably evaluate the zinc status. The aim of our study was to develop a biochemically validated questionnaire as a clinically useful tool that can predict the risk of an individual being zinc deficient. From 71 subjects aged 18-55 years blood and urine samples were collected. Zinc concentrations in serum and urine were determined by atomic absorption spectrometry...
