ABSTRACT

Objective To investigate the effect of salidroside on xenograft tumor of human pancreatic cancer cells BxPC-3 in nude mice.Methods BxPC-3 subcutaneous xenograft tumor nude mice model was established,and the mice were randomly divided into control group,salidroside 25 mg group and salidroside 50 mg group using random number method (6 mice in each group).25 mg/kg and 50 mg/kg salidroside by intragastric administration was performed per day for 3 weeks and the tumor was resected.The tumor was weighed and the diameter was measured.Cell apoptosis was detected by Tunel staining.Results As result,tumor weight was (1.561 ± 0.416)g in the control group,(0.742 ± 0.272)g in the 25 mg group and (0.276 ± 0.064) g in the 50 mg group respectively;tumor volume was (2354.35 ± 523.11) mm3,(991.43 ± 348.91) mm3 and (403.60 ± 130.98) mm3,respectively;and the apoptosis rate of the transplanted tumor cells was (23.74 ± 5.88) ％,(49.30 ± 6.75) ％ and (64.97 ± 6.99) ％,respectively,with significant difference among three groups (all P ＜ 0.01).The effect of salidroside on inhibiting proliferation and promoting apoptosis was dose dependent.Conclusions Salidroside can significantly inhibit the proliferation and growth of pancreatic cancer BxPC-3 cells via promoting cell apoptosis and inhibiting cell proliferation.
