The relative expression of E-cad protein was high, being 2.52- and 2.55-fold higher than that of the controls (p = 0.013, p = 0.049), while the relative expression of N-cad protein was low, being 0.55- and 0.59-fold higher than that of the controls in the endometria of patients with ovarian endometrioma and fibroids, respectively (p = 0.030, p = 0.043). This evidence concerns the gene CDH1 and leiomyoma.
