Cadmium metabolism in cdm/cdm mice

The uptake and metabolism of cadmium by cadmium-susceptible (+/+) and cadmium-resistant (cdm/cdm) strains of mice have been compared. These strains did not differ with respect to the quantitative uptake of cadmium into liver, kidney, or testis. After intraperitoneal administration of a nontoxic dose, more than 80% of the cadmium in liver and testis of both strains is bound to low molecular weight proteins. The chromatographic behavior of these cadmium-binding proteins is not affected by cdm genotype.
