The latter could well contribute to alterations in PGRMC1 abundance cited by this study.
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.
