Tungsten-enhanced growth of Methanosphaera stadtmanae.
BMC Res. Notes 5 , 238, (2012) The methanogenic Archaea Methanosphaera stadtmanae has been detected in the human gut microbiota by both culture and culture-independent methods. Its growth reaches an exponential phase after 5 to 7-day culture in medium 322 (10% vol). Our recent successful i... |

Efficient degradation of methabenzthiazuron photoinduced by decatungstate anion in water: kinetics and mechanistic studies.
Chemosphere 85(4) , 558-64, (2011) This study concerns the elimination of methabenzthiazuron (MBTU) photocatalysed by sodium decatungstate salts W10O32(4-)·(DTA) in aqueous solution under irradiation at 365 nm. Ninety percentage of MBTU (10(-4) M) is mineralised in the presence of the photocat... |

The potential reproductive, neurobehavioral and systemic effects of soluble sodium tungstate exposure in Sprague-Dawley rats.
Toxicol. Appl. Pharmacol. 254(2) , 133-7, (2011) The debate on tungsten (W) is fostered by its continuous usage in military munitions. Reports demonstrate W solubilizes in soil and can migrate into drinking water supplies and, therefore, is a potential health risk to humans. This study evaluated the reprodu... |

Anti-diabetic and anti-obesity agent sodium tungstate enhances GCN pathway activation through Glc7p inhibition.
FEBS Lett. 586(3) , 270-6, (2012) Tungstate counteracts diabetes and obesity in animal models, but its molecular mechanisms remain elusive. Our Saccharomyces cerevisiae-based approach has found that tungstate alleviated the growth defect induced by nutrient stress and enhanced the activation ... |

Novel inducers of the envelope stress response BaeSR in Salmonella Typhimurium: BaeR is critically required for tungstate waste disposal.
PLoS ONE 6(8) , e23713, (2011) The RpoE and CpxR regulated envelope stress responses are extremely important for Salmonella Typhimurium to cause infection in a range of hosts. Until now the role for BaeSR in both the Salmonella Typhimurium response to stress and its contribution to infecti... |

Anti-obesity sodium tungstate treatment triggers axonal and glial plasticity in hypothalamic feeding centers.
PLoS ONE 7(7) , e39087, (2012) This study aims at exploring the effects of sodium tungstate treatment on hypothalamic plasticity, which is known to have an important role in the control of energy metabolism.Adult lean and high-fat diet-induced obese mice were orally treated with sodium tun... |

Mycorrhization of the notabilis and sitiens tomato mutants in relation to abscisic acid and ethylene contents.
J. Plant Physiol. 167(8) , 606-13, (2010) We examined whether the reduced mycorrhization of abscisic acid (ABA)-deficient tomato mutants correlates with their incapacity in ABA biosynthesis and whether this effect is dependent on ethylene production. The mycorrhization of notabilis and sitiens mutant... |

Sodium tungstate modulates ATM function upon DNA damage.
FEBS Lett. 587(10) , 1579-86, (2013) Both radiotherapy and most effective chemotherapeutic agents induce different types of DNA damage. Here we show that tungstate modulates cell response to DNA damaging agents. Cells treated with tungstate were more sensitive to etoposide, phleomycin and ionizi... |

Exposure to sodium tungstate and Respiratory Syncytial Virus results in hematological/immunological disease in C57BL/6J mice.
Chem. Biol. Interact. 196(3) , 89-95, (2012) The etiology of childhood leukemia is not known. Strong evidence indicates that precursor B-cell Acute Lymphoblastic Leukemia (Pre-B ALL) is a genetic disease originating in utero. Environmental exposures in two concurrent, childhood leukemia clusters have be... |

Toxicity of sodium tungstate to earthworm, oat, radish, and lettuce.
Environ. Toxicol. Chem. 30(10) , 2312-8, (2011) Due to unknown effects of the potential exposure of the terrestrial environment to tungsten substances, a series of toxicity studies of sodium tungstate (Na(2) WO(4) ) was conducted. The effect on earthworm (Eisenia fetida) survival and reproduction was exami... |
