Expression level of DNA methyltransferases in NP and HP group. Expression and comparison of (A–D) DNMT1 and (E–H) DNMT3B in two compartments of endometrium from women with normal progesterone level and high progesterone level. 20 samples in each group were tested. There was no significant difference in the expression of DNMT1 between endometrium from HP and NP group. The expression of DNMT3B in endometrium from HP group was significantly higher than that from NP group. Red arrow indicates positive staining. Scale bar = 50 μm. GE glandular epithelia; LE luminal epithelia; SC stromal cell. Values expressed are mean + SEM. n.s., not significant
