FIG. 3.

The induction of MHR3 mRNA in GV1 cells in 6 h by 2 μg of 20E per ml in the presence of excess EcR-B1, USP-1, USP-2, or various combinations thereof under the control of the pIE1^hr constitutive promoter. The empty pIE1^hr was transfected as a control. Cells were cultured in the presence and absence of 20E hormone. Relative abundance refers to MHR3 RNA induced by 20E in 6 h in cells which contained the empty pIE1^hr expression vector, designated as 10. Means ± standard deviations (error bars) are shown (n = 3 to 5).
