ABSTRACT
ObjectiveTo study the effect of α7 ( α7 AChR) agonist nicotine on regulating sensitivity of regular chemotherapeutic agent in cholangiocarcinoma cells,and explore the possible target.MethodsThe effect of nicotine and α-BTX pretreatment on the survival ability of cholangiocarcinoma cells was investigated when applied with 5-FU by using MTT and Flat cloning formation experiment.ResultsApplied with 5-FU,in various con centrations nicotine stimulating group( 10-3 g/L,10-4 g/L,10-5 g/L ),the survive rate of QBC939 was 128%,124%,118%,while that in α-BTX stimulating group and combined stimulation group was 92%,94%,93%,92%,respectively.The cloning formation ability of nicotine- stimulating group (6.2 ± 0.40) was significantly higher than α- BTX stimulating group (3.2 ± 0.20 ),combined stimulation group ( 3.2 ± 0.20 ) and control group ( 3.4 ±0.33).ConclusionNicotine can prevent chemotherapy-induced apoptosis,and improve cholangiocarcinoma cell survival via α7 nicotine acetylcholine receptor in vitro.
