Relative mRNA expression of the progesterone receptors, (A) PR-total and (B) PR-B, and protein levels of (C) PR-A and (D) PR-B in paired samples of human myometrium and uterine leiomyoma. M = molecular weight marker. Data are expressed as median and interquartile range. *P<.05, Wilcoxon test.

3. Figure 2
Relative mRNA expression of progesterone receptor (PR) total and PR-B in leiomyoma samples from women classified according to the number of myomas and age. *P<.05; **P<.01, Mann-Whitney U test. The bottom picture shows Western blot bands of PR-A and PR-B in leiomyoma samples from women up to 40 years old with one to three myomas (lanes 1–2) and women over 40 years-old with more than three myomas (lanes 3–6).
