摘要

Objective: To investigate the effects of Chinese herbal formula Qinghuofu(QHF) on the migration and invasion of breast cancer MCF-7 cells and its possible molecular mechanisms, thereby providing a theoretical basis to find effective anti-cancer medicine and therapeutic targets for the treatment of anti-migration and anti-invasion of breast cancer.Methods: Breast cancer MCF-7 cells were treated with different QHF and other different reagents, CCK8 assay was used to detect the influence of the reagents on the proliferation of MCF-7 cells; Scrape migration and Transwell assay were used to quantitatively determine the migration and invasion effects of QHF and hepatocyte growth factor(HGF) on the MCF-7 cells. Subsequently, the c-Met inhibitor and its downstream ERK and PI3 K inhibitors were used to investigate the relationship between the migration and invasion of MCF-7 cells, as well as its downstream MAPK/ERK and PI3 K/Akt signaling pathways. The expression levels of HGF, c-Met, ERK, p-Akt, p-c-Met, p-ERK, p-Akt, MMP2, MMP9, and VEGF in breast cancer MCF-7 cells treated with QHF and other reagents were also examined.Results: The result indicated that formula QHF not only significantly inhibited the proliferation of MCF-7 cells, but also significantly suppressed the effects of HGF(40 ng/m L) on the proliferation and movement of MCF-7 cells, reducing the ability of the cells to invade and migrate. Western blot analysis indicated that QHF and c-Met inhibitor significantly decreased the expression of p-c-Met, p-ERK1, p-ERK2, p-Akt, MMP-2, MMP-9, and VEGF, while HGF significantly increased the expression of p-c-Met in MCF-7 cells; c-Met downstream ERK and PI3 K inhibitors also significantly decreased the expression of MMP-2, MMP-9, and VEGF in MCF-7 cells; But the difference among c-Met, PI3 K, ERK, and QHF group were not statistically significant.Conclusion: QHF can prevent the proliferation, migration, and invasion of MCF-7 cells by inhibiting the HGF/c-Met and its downstream PI3 K/Akt and MAPK/ERK signaling pathways; Thereby down-regulating the expression of HGF, p-Met, p-ERK1, p-ERK2, p-Akt, MMP-2, MMP-9, and VEGF.
