| 摘 要： | 目的探讨川芎嗪(Tetramethylpyrazine, TMP)对人肺腺癌细胞株AGZY抑制增殖、逆转耐药的作用。方法 应用MTT法检测TMP对耐阿霉素的AGZY细胞耐药情况的影响;通过绘制生长曲线、细胞集落形成实验观察TMP对AGZY细胞增殖情况的影响;应用穿膜实验检测TMP对AGZY细胞侵袭、转移情况的影响;应用Western blot方法检测TMP对AGZY细胞nm23、MDR1蛋白表达情况的影响。结果 TMP作用后, AGZY细胞对阿霉素的耐药性下降, IC50降低(P＜0.05);细胞的生长、增殖能力下降;细胞的穿膜能力降低(P＜0.05);TMP作用后, AGZY细胞中nm23蛋白表达上调、MDR1蛋白表达下调。结论 TMP可抑制AGZY细胞的增殖, 细胞的侵袭和转移能力的抑制与nm23表达的上调有关, 通过下调MDR1的表达达到逆转细胞耐药的作用。

| Abstract: | Objective To study the effects of tetramethylphylpyrazine(TMP)on cell proliferation and reversing drug resistance in human lung adenocarcinoma cell line AGZY.Methods The drug sensitivity of AGZY cells to ADM was measured by MTT assay.The cell proliferation states were investigate by cell growth curve and cell colony formation test.The migration and invasion of AGZY cells were measured with cell invasion assay.The protein expression levels of nm23 and MDR1 were determined by western blot analyses.Results The IC50 and drug-resistant index of ADM were decreased by TMP.Cell proliferation ability was decreased obviously.Cell invasion ability was decreased.The expression of nm23 was upregulated, and the expression of MDR1 was downregulated.Conclusion TMP could inhibit the growth of AGZY cell.TMP could enhance the AGZY cell chemosensitivity to ADM, and it maybe related with the down-regulation of MDR1.TMP can restrain AGZY cell invasion and metastasis, and it may have relationship with the upregulation of nm23. |
