Fig. 1: miR-30c expression was downregulated and BCL9 expression was upregulated in EMs tissues and cells.

A High-throughput transcriptome sequencing of miR-30c in eutopic and ectopic endometrial tissues of O-EMs patients and normal endometrial tissues (control); B Expression of BCL9 in EMs eutopic and ectopic tissues and normal endometrial tissues (control) in GSE7846 EMs-related microarray; C Expression levels of miR-30c and BCL9, determined by qRT-PCR, in 24 cases of EMs eutopic and ectopic tissues and 20 cases of normal endometrial tissues (Normal); D Pearson correlation analysis of the correlation between miR-30c and BCL9 expression in EMs ectopic tissues; E Expression levels of miR-30c and BCL9, determined by qRT-PCR, in ecto-EECs, euto-EECs, and normal EECs. Measurement data were characterized as mean ± SD. The comparison among data of multiple groups was performed with one-way ANOVA with Tukey’s post hoc test. Pearson correlation was used to analyze the correlation between miR-30c and BCL9 expression. *p < 0.05 versus the Normal group, #p < 0.05 versus the EMs eutopic tissue or the euto-EECs.
