2. Figure 1
Expression and comparison of (A–E) 5-mC in three compartments of endometrium from women with normal P level and high P level. The expression of 5-mC in the glandular epithelium of the high P group was significantly (P=.03) higher than that in the normal P group (E). The black arrow indicates positive staining. Scale bar = 50 μm. GE = glandular epithelia; LE = luminal epithelia; n.s. = not significant; SC = stromal cell. Values expressed are mean + SD. *P < .05.

3. Figure 2
Expression and comparison of (A–E) H3K4me2/3, (F–J) H3K9me2, and (K–O) H3K27me3 in three compartments of endometrium from women with normal P level and high P level. The expression level of H3K4me2/3 in all three compartments was not significantly different between the two groups (C, D, and E). The expression of H3K9me2 in the luminal epithelium and glandular epithelium of the high P group was significantly (P=.02 and P=.001, respectively) higher than that in the normal P group (H and J). The expression of H3K27me3 in the stroma of the high P group was significantly (P=.02) higher than that in the normal P group (N). The black arrow indicates positive staining. Scale bar = 50 μm. GE = glandular epithelia; LE = luminal epithelia; SC = stromal cell. Values expressed are mean + SD. *P < .05.

4. Figure 3
Expression and comparison of (A–E) H3K4ac and (F–J) H3K9ac in three compartments of endometrium from women with normal P level and high P level. The expression of H3K4ac in all three compartments was not significantly different between the two groups (C, D, and E). The expression of H3K9ac in the glandular epithelium of the high P group was significantly (P=.04) higher than that in the normal P group (J). Scale bar = 50 μm. GE = glandular epithelia; LE = luminal epithelia; n.s. = not significant; SC = stromal cell. Values expressed are mean + SD. *P < .05.
