CDH17 and endometriosis: The aim of this study was to evaluate the potential differential expression of E-CADHERIN and miR-200b in deeply infiltrating endometriotic (DIE) lesions, in ovarian endometriomas, and in the eutopic endometrium of women with endometriosis, in order to ascertain whether the EMT pathway miR-200b-ZEB1-E-CADHERIN is differentially regulated in different forms of endometriosis.
