Prevention by copper of cadmium sequestration by metallothionein in liver.

Abstract

Following chronic CdCl2 administration to rats, more than 98% of the metal in liver supernatant is bound to the low molecular weight binding protein, metallothionein. Simultaneous administration of high doses of Cd and copper salts result in an increase in toxicity which is accompanied by a failure of Cd sequestration by metallothionein in vivo. This may be… (More)
