In contrast to the decrease in GR mRNA seen in IM-9 cells after treatment with 1 microM dexamethasone for 16-18 h, treatment of 6TG1.1 cells resulted in an 8-fold increase in GR mRNA , as determined by Northern blot and RNase protection analysis , with a corresponding 3- to 4-fold increase in GR protein .
