Steroid-dependent regulation of mPRβ and γ in fallopian tubes of eCG-primed, immature mice. Forty-eight hours after eCG injection, the mice received an injection of E₂, P₄, the estrogen antagonist ICI 182.780, the progesterone antagonist CDB2914 or oil and were sampled two or six hours later. The levels of the target genes are normalized to the endogenous controls (GAPDH) and presented relative to the control group. Values are presented as mean ± SEM of five independent observations. The significance is shown as * P < 0.05 compared to the control group.
