Cytotoxic effects of combined treatment. (A) The cytotoxicity of curcumin alone or combined with GCB in T24-GCB cells. (B) The cytotoxicity of resveratrol alone or combined with GCB in T24-GCB cells. (C) The O/E ratio compared between GCB combined with low-dose (12.5 µM) or high-dose (25 µM) curcumin in T24-GCB cells. (D) The O/E ratio compared between GCB combined with low-dose (75 µM) or high-dose (150 µM) resveratrol in T24-GCB cells. Significant difference was observed between GCB-treated T24-GCB cells combined with low-dose and high-dose of resveratrol. *P<0.05, **P<0.01, ***P<0.001. GCB, gemcitabine; O/E, the ratio of observed deaths/expected deaths.
