Progesterone increases steady state mRNA levels of MDR-1 but does not change protein expression Here in this experiment mice treated with progesterone were sacrificed and the ovaries were used for qPCR as described previously and immunoblot. Significant differences were seen in the treatment groups, 0.25 mg and 0.5 mg, but not 1 mg
