Cytotoxicity and cytoprotective effects of kaempferol-3-o-sophorin (KOS). Control: BRL-3A cells exposed to various concentrations of KOS (0.8, 8, 40, and 80 μM) for 24 h and pretreated for 24 h with indicated KOS concentrations before treatment with 100 μM t-BHP. Statistical significance: ^#, ^##, ^###, and ^####, contrasted to the control group; , , , and , contrasted to the t-BHP-treated group.
