Abstract: Objective

To investigate anticancer activity and mechanism of osthole combined with cisplatin in human lung cancer cell NCI-H460.

Methods

NCI-H460 cells were treated with osthole(50, 100 and 200 μmol/L), cisplatin (1.5, 3.0 and6.0 μmol/L)and osthole combined with cisplatin (50 μmol/L osthole+1.5 μmol/L cisplatin), and the cell proliferation was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide(MTT) assay. NCI-H460 cells were treated with osthole (50 μmol/L), cisplatin (1.5 μmol/L)and osthole combined with cisplatin (50 μmol/L osthole+1.5 μmol/L cisplatin), and then the induction of apoptosis was determined by Annexin Ⅴ/ propidium iodide(PI) staining, and the generation of reactive oxygen species (ROS) was determined by dihydroethidium (DHE) staining. Furthermore, N-acetylcysteine (NAC) was used to determine the apoptosis induced by above treatments. Untreated NCI-H460 cells were taken as control group.

Results

Osthole and cisplatin showed the dose dependent inhibition of the NCI-H460 cell proliferation. The 50 μmol/L osthole combined with 1.5 μmol/L cisplatin can significantly inhibit NCI-H460 cell proliferation and induce its apoptosis. Compared to single treatments, combined treatment can significantly increase the ROS positive cells(P<0.05). Compared to the control group, NCI-H460 cells treated with NAC produced obviously the decreasing of ROS, apoptosis and cell proliferation(P<0.05).

Conclusions

Osthole combined with cisplatin can cause the apoptosis of NCI-H460 cells by inducing production of ROS.
