The regulation of metallothionein (MT) gene expression in a cadmium resistant CHO cell line which overproduces MT was examined in this study. The results show that MT and mRNA levels reach a maximum 24-30 h after a primary zinc exposure and, subsequently, MT mRNA concentrations decline. This decrease in MT mRNA levels can be correlated with the accumulation of metallothionein and decreased rates of zinc and cadmium uptake.
