Studying the relationship between the expression levels of miR-135a and HOXA10 genes expression in the eutopic endometrial tissue samples in patients with endometriosis, stated that there was a significant relationship between the higher expression of miR-135a and decreased expression of HOXA10 in the eutopic endometrium of the patients with endometriosis that was in agreement with our findings (16). This evidence concerns the gene HOXA10 and endometriosis.
