We assessed ROS levels across multiple ovarian cell types including T80 (immortalized normal ovarian surface epithelial cell line), T80+H-Ras (T80 cells overexpressing H-Ras), HEY (serous epithelial ovarian carcinoma cell line), TOV112D (endometrioid ovarian carcinoma cell line) and TOV21G (clear cell ovarian carcinoma cell line) which were treated with 250 μM FAC. Here, HRAS is linked to ovarian clear cell cancer.
