Nrf2 expression in different ovarian lesions, we noticed that increased mean expression in carcinoma (72%, mean ± SD: 32.70 ± 29.44) than other examined lesions (0% for normal; 25%, mean ± SD: 10.30 ± 14.50 for benign tumors; and 20%, mean ± SD: 14.60 ± 19.33 for borderline tumors), and the difference reached a significant statistical level (P = 0.004) (Table 2, Fig.4c). Here, NFE2L2 is linked to benign neoplasm.
