ZEB1 and endometriosis: ZEB1 and miR-200b are significantly under-expressed in the eutopic endometrium of women without deep infiltrative endometriosis (ZEB1 p = 0.001, miR-200b p < 0.001), while they are over-expressed in the eutopic endometrium of women with deep infiltrative endometriosis (ZEB1 p = 0.207, miR-200b p = 0.225).
