摘要

目的:研究消瘕方对人乳腺癌MDA-MB-435细胞株裸小鼠移植瘤中血管内皮生长因子(VEGF)表达的影响。方法:以体外培养的人乳腺癌MDA-MB-435细胞接种于裸小鼠右腋部位制造裸鼠皮下移植瘤模型

随机分为生理盐水组、5-氟尿嘧啶组及消瘕方小

中

大剂量组

每组小鼠予以相应药物治疗6周后脱颈处死

称瘤重

计算肿瘤生长抑制率

并采用RT-PCR法、免疫组化法检测肿瘤组织中VEGFmRNA及蛋白的表达。结果:消瘕方可抑制乳腺移植瘤生长

降低瘤体内VEGFmRNA表达(P<0.05)

下调相应VEGF蛋白表达(P<0.05)

其中以中剂量组效果更明显。结论:消瘕方的抑瘤作用与其下调瘤体内VEGF表达密切相关。

Abstract

Objective: To study the effects of Xiaojia Decoction on expression of Vascular Endothelial Growth Factor in transplantation tumors of the breast cancer cell line MDA-MB-435 in nude mice.Methods: The MDA-MB435 human breast cancer cells cultured in vitro were subcutaneously inoculated into BALB/c nude mice to establish the transplanted tumor model.The mice were then randomized into five groups and treated with Xiaojia Decoction or other remedies for 6 weeks.Then we sacrificed the mice and weighed the tumor

calculated the inhibitory rate of tumor weight

the expression of VEGF on mRNA and protein level was determined by means of RT-PCR and immunohistochemical assay.Results: Xiaojia Decoction could inhibit the growth of tumor conspicuously

lower the expression of both mRNA and protein level of VEGF(P<0.05)

especially for the medium-dose group.Conclusion: This Decoction's effects on down-regulating VEGF have close relation with its function of inhibiting the tumor growth.
