摘要
目的:探讨乳宁方体外抗乳腺癌复发转移的作用机制。方法:SD雌性大鼠,分为乳宁方治疗组、乳宁方拆方温肾方治疗组、乳宁方拆方疏肝活血方治疗组、三苯氧胺(tamoxifen,TAM)治疗组、环磷酰胺(cyclophosphamide,CTX)治疗组、空白对照组,每组10只,制备含药血清。MDA-MB-435细胞传代培养,分别加入药物血清常规培养,采用体外matrigel细胞侵袭能力实验检测细胞的侵袭能力、实时逆转录聚合酶链反应法检测细胞血管内皮生长因子(vascularendothelialgrowthfactor,VEGF)、金属蛋白酶组织抑制物-1(tissueinhibitorofmetalloproteinase-1,TIMP-1)、基质金属蛋白酶-9(matrixmetalloproteinase-9,MMP-9)基因表达。结果:CTX治疗组、TAM治疗组、疏肝活血方治疗组血清均可下调MDA-MB-435细胞VEGF基因表达;CTX治疗组、乳宁方治疗组、温肾方治疗组血清可上调MDA-MB-435细胞TIMP-1基因表达,并能下调MMP-9基因表达。结论:乳宁方抑制MDA-MB-435侵袭的作用可能与影响MMP-9/TIMP-1的平衡性,以抑制肿瘤细胞的侵袭和转移有关。
Objective: To explore the mechanisms of the effects of Runing Recipe in anti-invasion and anti-recurrence of breast cancer by experimental research in vitro. Methods: SD female rats were randomly divided into Runing Recipe-treated group and its decomposed formulas Kidney-Warming Recipe and Liver-Soothing Recipe-treated groups, tamoxifen (TAM) -treated group, cyclophosphamide (CTX) -treated group, and normal control group to make medicated serums. Methods of matrigel basement membrane and real-time reverse transcription polymerase chain reaction were employed to investigate the gene expressions of vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) after MDA-MB-435 cells were treated with the medicated serums. Results: The gene expression of VEGF was dropped in CTX-treated, TAM-treated and Liver-Smoothing Recipe-treated groups. The gene expression of TIMP-1 was up-regulated in CTX-treated, Runing Recipe-treated and Kidney-Warming Recipe-treated groups; while MMP-9 was down-regulated in these groups. Conclusion: The mechanisms of Runing Recipe in inhibiting the cancer cell invasion may be related to down-regulating the gene expressions of VEGF and MMP-9, and up-regulating the gene expression of TIMP-1.
