The role of ROS and NF- κB pathway in olmesartan induced-toxicity in HeLa and mcf-7 cell lines

In this study we investigated toxicity mechanism of olmesartan in HeLa and MCF-7 cell lines. HeLa and MCF-7 cells were cultured in DMEM in optimum conditions. Cells were pretreated with rutin as an antioxidant and treated with olmesartan as a cytotoxic agent. Cell proliferation was determined by MTT assay. The role of ROS was determined using DCFH-DA by flow cytometry analysis. Also, cells were treated with olmesartan (5mM) and Bay 11-7-82 (25μM) for 24h, then expression of apoptotic proteins including Bax, caspase3 and IκB were investigated in both cell lines by western blotting. Cell viability decreased with olmesartan in malignant cell lines. Kinetic of ROS assay showed increment of ROS generation starting at 2h which peaked at 4h after treatment. Pretreatment with antioxidant rutin d...
