We studied metallothionein (MT) response in the manure worm Eisenia fetida after exposures to cadmium (Cd), zinc (Zn) or cadmium and zinc spiked media. MT was studied both at the protein level by Dot Immunobinding Assay, (DIA) and at the expression level by Northern blotting. Cd was highly accumulated by worms whereas Zn body concentration was regulated. In addition, Zn would limit Cd accumulation in worms exposed to low Cd concentrations (1 and 8 mg Cd kg(-1) of dry soil). Exposure to a… CONTINUE READING
