Half-maximal induction of GR mRNA and protein in 6TG1.1 cells was observed between 10-100 nM dexamethasone , and inclusion of 1 microM RU 38486 completely blocked the effects of 100 nM dexamethasone , demonstrating that positive autoregulation of GR expression in 6TG1.1 cells is a receptor-mediated response.
