Previous immunohistochemical studies revealed that postmenopausal EPs appear to show variable intensity of oestrogen and progesterone receptor expression [17,18,19,20,21] and several studies have attempted to assess proliferation and apoptosis markers such as Ki67 [22,23], cyclin D1 [21], p53 [24,25] and bcl-2 [17] in the endometrial polyps, with different results. The gene discussed is BCL2; the disease is endometrial polyp.
