Dexamethasone stimulation of metallothionein synthesis in HeLa cell cultures

M Karin and HR Herschman

HeLa cells in culture synthesize metallothionein. To investigate the effects of glucocorticoids on metallothionein synthesis we adapted HeLa cells to growth in a defined medium lacking hydrocortisone. In this defined medium, containing 1.5 x 10(-6)M Zn2+, dexamethasone (10(-6)M) caused a five- to sixfold increase in the synthesis of metallothionein. Progesterone (10(-5)M), a known antagonist of glucocorticoids, inhibited this response by 50 percent.
