As you suggested, we should have presented the data in the same graph. However, the two experiments were performed independently. Therefore, we were not able to combine the results in the graph. Because treatment with P4 alone could not induce decidualization in the experiments, we examined the effect of PGRMC1 knockdown and inhibition on db-cAMP-induced decidualization. Further study would be needed to determine whether PGRMC1 is involved in the P4 action in endometrium.
Line 189-96. The paragraph describes a result showing that the results are independent of P4. However, the control structure of comparisons is incorrect. The simplest direct comparison would be db-cAMP/P4 vs. db-cAMP to permit the argument the authors are presenting. However, the effects of P4 in the absence of db-cAMP would also require control in cells without db-cAMP, +/- P4. The statistical significance of any result would be evaluated using multivariate analysis.
