title: Inducibility of metallothionein biosynthesis in cultured normal and Menkes kinky hair disease fibroblasts: effects of copper and cadmium.
abstract: Metallothionein biosynthesis is not induced by extracellular copper in Menkes Kinky hair disease (MKHD) or in normal cultured fibroblasts under the conditions of these experiments. In the presence of copper, MKHD fibroblasts also incorporated less cysteine than did normal fibroblasts. Extracellular cadmium greatly enhanced the uptake of cysteine in both normal and MKHD cultures. By the technique of polyacrylamide gel electrophoresis, it was demonstrated that metallothionein is induced by cadmium in normal and MKHD-cultured fibroblasts.
