Figure 3. Clinical correlation analysis of selected m6A regulators in EMs. (A) HNRNPC and HNRNPA2B1 showed differential expression in different r-AFS stages in EU samples. However, no m6A regulators showed any significant changes across different r-AFS stages in EC samples (B), in different stages of the menstrual cycle, in different age groups for both EU and EC samples (C–F), and different races for the EU samples (G). Moreover, METTL3 and YTHDF2 were differentially expressed in different subtypes of EM in EC samples (H). ‘Wilcox.test’ was used for comparison between two groups. EMs, endometriosis; r-AFS, the revised American Fertility Society; NM, normal endometrium; EU, eutopic endometrium; EC, ectopic endometrium. NS - not significant; * p < 0.05; ** p < 0.01; *** p < 0.001.
