摘要: 目的 探究丹参酮IIA(Tan ⅡA)抗血小板作用以及抑制人血小板与结肠癌HCT116细胞的相互作用。方法 采用不同浓度Tan ⅡA(10、20、40 μmol/L)处理健康志愿者全血或血小板,通过血栓弹力图试验(TEG)检测二磷酸腺苷(Adenosine diphosphate,ADP)、花生四烯酸(arachidonic acid,AA)抑制率,流式细胞术检测血小板CD62P、PAC-1表达率,黏附试验检测Tan ⅡA处理后血小板与HCT116细胞的黏附情况,划痕试验检测Tan ⅡA处理后血小板对HCT116细胞的迁移能力的影响。结果 TEG结果表明,Tan IIA呈浓度依赖性抑制ADP、AA诱导的血小板聚集(P<0.01),低浓度Tan ⅡA处理就能获得较好的ADP抑制率,为(73.48±19.63)%,高浓度Tan ⅡA才能获得较好的AA抑制率,为(78.20±18.58)%。流式细胞术结果显示,Tan ⅡA可以呈浓度依赖抑制凝血酶或ADP诱导的血小板表面CD62P、PAC-1表达(P<0.05)。黏附试验结果证实,Tan ⅡA能显著抑制凝血酶或ADP激活血小板与HCT116细胞之间的黏附作用,抑制能力与Tan ⅡA浓度呈正相关。划痕试验结果发现,活化血小板可促进HCT116细胞迁移,采用低浓度(10 μmol/L)Tan ⅡA处理血小板就可显著抑制肿瘤细胞的迁移。结论 Tan ⅡA可通过抑制血小板聚集和活化,进而抑制血小板与肿瘤细胞的相互作用。

Abstract: Objective To investigate the antiplatelet effect of tanshinone ⅡA (Tan IIA) and its inhibition effect of the interaction between human platelets and HCT116 cells of colon cancer. Method Whole blood or platelets of healthy volunteers were treated with different concentrations of Tan ⅡA (10, 20, 40 μmol/L), and inhibition rate of platelet aggregation triggered with Adenosine diphosphate (ADP) and arachidonic acid (arachidonic acid) were detected by TEG. The expression rates of CD62P and PAC-1 in platelets were detected by flow cytometry, the adhesion test was used to detect the adhesion of platelets to HCT116 cells after Tan ⅡA treatment, and the effect of platelets on the migration ability of HCT116 cells after Tan ⅡA treatment was tested by scratch test. Results The TEG results showed that Tan ⅡA inhibited ADP and AA-induced platelet aggregation in a concentration-dependent manner (P<0.01), low concentration Tan ⅡA treatment can obtain higher ADP inhibition rate, which is (73.48±19.63) %, high concentration Tan ⅡA treatment can obtain higher AA inhibition rate, which is (78.20±18.58) %. Flow cytometry detection showed that Tan IIA inhibited thrombin or ADP-induced expression of CD62P and PAC-1 on platelet surface in a concentration-dependent manner (P<0.05). Adhesion test results confirmed that Tan ⅡA could significantly inhibit the adhesion between thrombin or ADP-activated platelets and HCT116 cells, and the inhibition ability was positively correlated with Tan ⅡA concentration. The results of scratch test showed that activated platelets could promote the migration of HCT116 cells, and treatment of platelets with low concentration (10 μmol/L) Tan ⅡA could significantly inhibit promotion of platelet to the migration of tumor cells. Conclusion Tan IIA can inhibit the interaction between platelets and tumor cells by inhibiting platelet aggregation and activation.
