PloS one, 7(7), e39087-e39087 (2012-07-18)
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
Josie E Bamford et al.
Environmental toxicology and chemistry, 30(10), 2312-2318 (2011-08-02)
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 examined using

Diabetes, obesity & metabolism, 13(3), 235-242 (2011-01-06)
Sodium tungstate is an anti-obesity drug targeting peripheral tissues. In vivo, sodium tungstate reduces body weight gain and food intake through increasing energy expenditure and lipid oxidation, but it also modulates hypothalamic gene expression when orally administered, raising the possibility
Delia Zafra et al.
FEBS letters, 587(3), 291-296 (2012-12-25)
Tungstate treatment ameliorates experimental diabetes by increasing liver glycogen deposition through an as yet unidentified mechanism. The signalling mechanism of tungstate was studied in CHOIR cells and primary cultured hepatocytes. This compound exerted its pro-glycogenic effects through a new G-protein-dependent
Gustavo S Guandalini et al.
Chemical research in toxicology, 24(4), 488-493 (2011-03-08)
Heavy metal tungsten alloys have replaced lead and depleted uranium in many munitions applications, due to public perception of these elements as environmentally unsafe. Tungsten materials left in the environment may become bioaccessible as tungstate, which might lead to population
