红景天苷抑制人血小板与乳腺癌MDA-MB-468 细胞相互作用的实验研究
Inhibitory effect of Salidroside on the interaction between human platelets and breast cancer MDA-MB-468 cells
摘要
Abstract
Objective To study the effect of Salidroside(Sal)on platelet activation and aggregation and the interaction between human platelets and MDA-MB-468 cells of breast cancer.Methods Human platelets were collected,platelet sus-pension was prepared,and platelets were treated with different concentrations of Sal.The effects of Sal on platelet activation and aggregation were detected by thromboelastogram(TEG)and flow cytometry.Breast cancer MDA-MB-468 cells were cul-tured in vitro,and human platelets were treated with different concentrations of Sal,and then activated by thrombin.The effects of Sal on the interaction between platelets and MDA-MB-468 cells were analyzed by adhesion test and scratch test.Re-sults TEG detection:The ADP inhibition rate in the blank control group was(10.97±12.69)%,and the ADP inhibition rate in all Sal intervention groups was higher than that in the blank control group(P＜0.05).The AA inhibition rate was(8.11±7.84)%in the control group and(25.96±15.18)%in the 5 μmol/L Sal intervention group,and the difference was statistically significant(P＜0.05).Flow cytometry:The expression of CD62P on platelet surface in 40 and 60 μmol/L Sal groups was(56.5±0.17)%and(65.50±0.36)%,respectively,and the difference was statistically significant compared with the positive control group(76.53±0.49)%(P＜0.05).The percentages of PAC-1 expression on platelet surface in 40 and 60 μmol/L Sal groups were(62.20±0.10)%and(58.47±0.15)%,and the difference was statistically significant com-pared with the positive control group(72.10±0.20)%(P＜0.05).Adhesion experiment:Platelets can have adhesion with MDA-MB-468 cells,and activated platelets have stronger adhesion ability.The adhesion rate in the Sal group was signifi-cantly lower than that in the positive control group,and was negatively correlated with the concentration of Sal.Scratch test:The cell mobility at 24 h in the positive control group was(12.71±0.70)%,and the cell mobility in each Sal treatment group was(4.51±0.44)%,(3.85±0.11)%,(5.37±0.36)%,(4.15±0.13)%and(3.55±0.38)%,respectively,showing significant decrease compared with the positive control group(P＜0.05).After 48 h of Sal treatment,the cell mobility of 10,20,40 and 60μmol/L Sal groups decreased,and there was a statistical difference compared with the positive control group(P＜0.05).Conclusion Sal can inhibit the adhesion between activated platelets mediated by thrombin and MDA-MB-468 cells and the migration of MDA-MB-468 cells.关键词
