摘要

目的:研究藏花素（Crocin）对膀胱移行细胞癌T24细胞血管内皮生长因子C（Vascular endothelial growth factor

VEGF-C）表达水平的影响。方法:采用MTT法测定不同浓度及不同时间藏花素对T24细胞抑制率

选出最佳药物浓度和最佳作用时间。用RT-PCR和基因芯片分别检测最佳作用时间和最佳药物浓度作用前后T24细胞VEGF-C的表达。结果:MTT显示藏花素抑制T24细胞生长具有时间和剂量依从性

3mmol/L藏花素作用48h对T24细胞的抑制率最高。RT-PCR显示藏花素组VEGF-C表达明显减少

基因芯片扫描结果中藏花素组VEGF-C表达也显著下调。结论:藏花素抑制T24细胞增殖

可能与下调VEGF-C的表达

从而减少肿瘤血管的生成有关。

Abstract

Objective:To study the effect of Crocin on the expression of VEGF-C in transitional cell carcinoma of bladder (TCCB) T24 cell. Methods:T24 cells were treated with Crocin. MTT assay was adopted to determine the inhibition rate for selecting the best effect time and concentration of Crocin. The reverse transcription polymerase chain reaction(RT-PCR) and cDNA microarray were used to evaluate VEGF-C mRNA expression of T24 cells at around the best effect time and as the Crocin concentration reached the best. Results:The growth of T24 cells was inhibited significantly(P<0.05) at 3mmol/L Crocin when treated for 48h. And there was a marked positive correlation between Crocin concentration

time and inhibition rate. RT-PCR showed that VEGF-C mRNA expression in Crocin treated group was significantly lower than that of the control group. The cDNA microarray analysis was coincided well with the RT-PCR data. Conclusion:Crocin inhibits the proliferation of T24 cells and the mechanism might be decreasing tumor angiogenesis by down-regulating the expression of VEGF-C.
