PCR results for ERα, ERβ and GPR30. Representative real-time PCR experiments for expression of ERα (upper), ERβ (middle) and GPR30 (bottom) mRNAs in human cervix from the C (n = 11), R (n = 10) and NR (n = 4) groups respectively. The values of relative expression of target genes were normalized against cyclophilin A and displayed in arbitrary units. The "box-and-whisker plot" represents the median value with 50% of all data falling within the box. The whiskers extend to the 5th and 95th percentiles.
