STF-083010 enhances ER stress-mediated apoptosis in ovarian cancer cells (OVCAR3 and SKOV3). Caspase-3 and -12 activities measured by specific fluorometric assay kit (a, b) and measurement of Bax and Bcl-2 protein levels using western blotting (c). Results were manifested as mean ± SD and *p < 0.05, **p < 0.01, ***p˂0,001 versus control. #p < 0.05, ##p < 0.01, ###p˂0.001 versus Tm (3 μg/mL) considered as significant
