Randomized trial reveals glucocorticoid hormone receptors increase metallothionein synthesis in HeLa cells, suggesting new therapeutic targets.

This research aims to explore how glucocorticoid hormone receptors influence metallothionein synthesis in HeLa cells.
HeLa cells were grown in a glucocorticoid-free medium to assess metallothionein synthesis.
Dexamethasone and hydrocortisone were used to stimulate metallothionein production at various concentrations.
Binding studies with 3H-dexamethasone were conducted to evaluate receptor characteristics.
Metallothionein synthesis increased 5- to 10-fold with optimal concentrations of 10(-8)M dexamethasone and 10(-7)M hydrocortisone.
Half-maximal induction was observed at 5 X 10(-9)M dexamethasone and 5 X 10(-8)M hydrocortisone.
HeLa cells contained 25,000 specific 3H-dexamethasone receptors that translocate to the nucleus after one hour.
