Cadmium Accumulation and Metallothionein Biosynthesis in Cadmium-Treated Freshwater Mussel Anodonta woodiana
This study investigated the distribution of cadmium (Cd) and the protein level of metallothionein (MT) and examined the relationship of Cd accumulation and the MT concentration in different tissues of freshwater mussel Anodonta woodiana following Cd treatment. The mussels were exposed to Cd (4.21, 8.43, 16.86, 33.72 and 67.45 mg L-1) for 24, 48, 72 and 96 h, respectively. After Cd treatment, th...
متن کاملResponse of metallothionein concentrations in a freshwater bivalve (Anodonta grandis) along an environmental cadmium gradient
Surficial (oxic) sediments, overlying water, and specimens of the freshwater bivalve Anodonta grandis were collected by divers at 11 littoral lacustrine sites located along a geochemical gradient of pH, [Cd], Dl, and [Z n in an area influenced by mining and smelting activities. The molluscs were dissected (gills; 1 hepatopancreas; remaining tissues) and analyzed for Cd, Cu, Zn, and metallothion...
متن کاملCrystals of cadmium, zinc metallothionein.
Single crystals have been grown of Cd,Zn metallothionein isoform II from rat liver. The space group is P41212(P43212) with unit cell dimensions a = b = 31.0 A and c = 120.0 A, and one molecule in the crystallographic asymmetric unit. The crystals are square bipyramids elongated on the tetragonal c-axis and are grown by repetitive seeding. The crystals are suitable for high resolution structure ...
متن کاملCadmium-binding protein (metallothionein) in carp.
When carp (Cyprinus carpio) were exposed to 5 and 30 ppm Cd in the water, the contents of Cd-binding protein, which has low molecular weight, increased in the hepatopancreas, kidney, gills and gastrointestinal tract with the duration of exposure. This Cd-binding protein was purified from hepatopancreas, kidney, gills, and spleen of carp administered 2 mg/kg Cd (as CdCl2), intraperitoneally for ...
متن کاملDietary protein effects on cadmium and metallothionein accumulation in the liver and kidney of rats.
The relationship of dietary protein to cadmium absorption and tissue deposition was studied in male Sprague-Dawley rats exposed to different levels of cadmium in the drinking water. In animals fed a high-protein or low-protein diet and drinking water containing 25 or 50 ppm cadmium, liver and kidney cadmium and metallothionein were both significantly higher in rats fed the high-protein diet for...
