Abstract:
Objective:Xanthohumol is a kind of isoamyl olefinic flavonoid natural compounds,which have antitumor activity and impact on a variety of cell signaling pathways,The objective of this study was to explore the effects of xanthohumol on proliferation and apoptosis of thyroid cancer cells B-CPAP through the Notch signaling pathway.Methods:B-CPAP cells were cultivated in vitro,Xanthohumol was divided into control group(0 μ mol/L),low dose group(10 μ mol/L),middle dose group(20 μ mol/L),high dose group(40 μ mol/L)according to the different concentrations,The logarithmic growth cells were cultivated with different concentrations of xanthohumol intervention,application of MTT colorimetry in the detection of proliferation inhibition rates of B-CPAP cells.B-CPAP cells morphological changes were observed by using fluorescence microscope after appli-cation of Hoechst 33258 dyeing.B-CPAP cells apoptosis were detected by Annexin V-FITC/PI flow cytometry.Notch signaling pathway related proteins were determined?by?Western blotting.Re-sults:MTT showed that low dose group,middle dose group and high dose group,respectively pro-cessing after 24h,48h,72h,proliferation inhibition rates of the three groups were statistical?signifi-cance(F=189.34,131.73,124.51,P＜0.05);Respectively treated after 24h,48h,72h,proliferation in-hibition rates of xanthohumol increased over time in the same group,The differences were statisti-cally significant(F=204.51,169.64,183.15,P＜0.05).B-CPAP cells of high dose group appeared ob-viously apoptosis morphological changes compared with the control group through Hoechst33258 dying.Flow cytometry showed apoptosis rates of concrol group,low dose group and high dose group compared were statistical?significance(F=1235.54,P＜0.05).Apoptosis rate was higher in the high-dose group.Western blotting showed that Notch1,Treatment was performed for 72h,Hes1,Bcl-2 expression were significantly decreased in low dose group,middle dose group and high dose group compared with the control group(F=203.22,161.52,224.78),while cleaved caspase-3 ex-pression significantly increased(F=463.27),the differences were statistically significant(P＜0.05).Conclusions:Xanthohumol inhibits B-CPAP cells proliferation and induces cells apoptosis maybe through the Notch signaling pathway.
