摘要
目的观察槐耳板蓝根双向发酵产物对乳腺癌MCF-7细胞迁移、侵袭和相关因子的影响,探讨其相关机制。方法以人乳腺癌MCF-7细胞为模型,实验分为对照组、板蓝根组、槐耳组和槐耳板蓝根组。MTT法检测细胞增殖;细胞划痕实验检测MCF-7细胞迁移能力;Transwell细胞侵袭实验检测MCF-7细胞侵袭能力;细胞黏附实验检测MCF-7细胞黏附能力;半定量RT-PCR检测MCF-7细胞基质金属蛋白酶(MMP-9)和波形蛋白(Vimentin)基因表达。结果与板蓝根组和槐耳组比较,槐耳板蓝根组明显抑制MCF-7细胞增殖、迁移、侵袭和黏附(P<0.05),抑制MMP-9和Vimentin的基因表达(P<0.05)。结论槐耳板蓝根双向发酵提取物可能通过下调MMP-9和Vimentin的基因表达抑制乳腺癌MCF-7细胞迁移、侵袭。
Objective To observe the effects of Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products on the migration and invasion of human breast cancer MCF-7 cells and relevant factors; To discuss relevant mechanism of action. Methods Breast carcinoma cell line MCF-7 was used as research subject in this experiment. Control group, Isatidis Radix group, Trametes robiniophila Murr group, and Trametes robiniophila Murr and Isatidis Radix group were included in the experiment. The effects of Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products on MCF-7 cell proliferation were measured by MTT method. Cell scratch assay, transwell assay and adhesion assay were used to measure the effects of Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products on the migration, invasion and adhesion capability of MCF-7 cells, respectively. The effects of Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products on the m RNA expression of MMP-9 and Vimentin were measured by RT-PCR. Results Compared with Isatidis Radix group and Trametes robiniophila Murr group, Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products could significantly inhibit the proliferation, migration, invasion and adhesion capability of MCF-7 cells(P<0.05). Similarly, Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products reduced the m RNA expression of MMP-9 and Vimentin(P<0.05). Conclusion Trametes robiniophila Murr and Isatidis Radix bidirectional fermentation products may down-regulate the expression of MMP-9 and Vimentin to inhibit the migration, invasion and adhesion capabilities of MCF-7 cells.
