Protection against zinc toxicity by metallothionein and zinc transporter 1.
Cells protect themselves from zinc toxicity by inducing proteins such as metallothionein (MT) that bind it tightly, by sequestering it in organelles, or by exporting it. In this study, the interplay between zinc binding by MT and its efflux by zinc transporter 1 (ZnT1) was examined genetically. Inactivation of the Znt1 gene in baby hamster kidney (BHK) cells that do not express their Mt genes r...
متن کاملThe effect of zinc ions
The fertilization rate of mouse gametes in a Krebs-Ringer bicarbonate medium was 60%. The rate fell to 0% when 250 \g=m\M-ZnCl2 was added, but MgCl2, CaCl2, MnCl2, FeCl2 and CuCl2 (each at 250 \g=m\M)had no effect. The inhibitory effect of Zn2+ was not evident if the spermatozoa or eggs were preincubated with Zn2+ or if previously capacitated spermatozoa were used. The Zn2+ is thought to act by...
متن کاملCetylpyridinium Chloride Micelle-mediated Mutual Separation of Zinc, Cadmium, and Mercury Ions by Thin-layer Chromatography
Cationic surfactant-mediated systems containing different concentrations of cetylpyridinium chloride have been used as mobile phases in thin-layer chromatographic separation of metal cations on silica layers. The effect of surfactant concentrations below and above the critical micelle concentration (CMC) on the retention behaviour of metal ions was examined. The best TLC system for rapid mutual...
متن کاملSelective binding of zinc ions
The relative binding affinity of Zn2+ to several glycosaminoglycans was determined by gel-filtration chromatography. Binding was observed only between Zn2+ and heparin. No binding was observed between Zn2+ and chondroitin 4-sulphate, chondroitin 6-sulphate, dermatan sulphate or hyaluronic acid. All of the glycosaminoglycans contained carboxy groups, but only heparin bound Zn2+. This observation...
متن کاملRemoval of Pb(II) and Cu(II) Ions from Aqueous Solutions by Cadmium Sulfide Nanoparticles
In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the met...
