CB1 and PCNA protein expression in JZSMCs from normal and adenomyotic women across different phases of the menstrual cycle was determined by Western blotting. a Proteins were extracted from the JZSMCs of women in both groups in the secretory phase (Secre) and proliferative phase (Proli) and subjected to Western blot analysis. β-Actin was assayed in parallel as an internal control. b Quantitative analysis of average CB1 and PCNA protein levels in each group normalized to β-actin. Three independent experiments were conducted for each treatment. One representative image from each group of three experiments is shown. The error bars on all histograms indicate the standard deviation. *, P < 0.05; **, P < 0.01
