Abstract

Abstract: Objective The objective of this study was to observe the effect of AEG-1 gene on the metastasis in breast cancer MCF-7 cells.Methods AEG-1 siRNAs were transfected into MCF-7 cells to silence AEG-1 expression,and negative siRNA was used as a control.Transwell chamber was used to detect the ability of cell migration and invasion of MCF-7 cells.CCK8 assay was used to detect the cell proliferation of MCF-7 cells.At the same time,the effect of VEGF on the angiogenesis was investigated by detecting the changes of lumen formation in HUVEC cells.Results The migration,invasive and proliferative abilities were significantly inhibited in MCF-7 cells transfected with AEG-1 siRNA.Knockdown AEG-1 was significantly decreased the level of VEGF in the supernatant of MCF-7 cells.Knockdown AEG-1 was also significantly inhibited the angiogenesis activity in HUVEC cells.Conclusion Knockdown AEG-1 can significantly inhibit the migration of MCF-7 cells,including cell migration,invasion,proliferation and angiogenesis.These results suggest that AEG-1 plays an important role in the metastasis process of breast cancer and opens up new ideas for future treatment breast cancer.
