摘要
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 × 10-6M Zn2+, dexamethasone (10 -6M) caused a five- to sixfold increase in the synthesis of metallothionein. Progesterone (10-5M), a known antagonist of glucocorticoids, inhibited this response by 50 percent. Copyright © 1979 AAAS.
