FIG. 2.

Dose-dependent effect of dexamethasone on RET mRNA. (A) Northern analysis. TT flasks were treated in triplicate with vehicle (EtOH) or with dexamethasone at the doses shown for 24 h. Lanes were hybridized to RET and 36B4 riboprobes sequentially. (B) Quantification of the results obtained by Northern analysis. RET mRNA species were quantitated and adjusted using hybridization to 36B4 sequence as a control for loading. The mean and SD of each triplicate were then expressed as a percentage of vehicle-treated control samples. Significant differences when compared to control results are shown: *p < 0.05, **p < 0.01, ***p < 0.005.
