ABSTRACT
Objective:
To clarify the effect of voltage-gated proton channel 1 (Hv1) on the migration and invasion of breast cancer cells.Methods:
The protein expression of Hv1 was detected in human breast cancer cell lines with different metastatic abilities. SiRNA technique was used to down-regulate the expression of Hvl in breast cancer MDA-MB-231 cells. Scratch and matrigel invasion methods were used to observe the effect of Hvl on the migration and invasion of breast cancer cells, and the relevant molecular mechanism was explored.Results:
Hv1 was highly expressed in the highly metastatic breast cancer cell line MDA-MB-231. Hvl was more highly expressed in MDA-MB-231 cells with higher metastatic ability. The SiRNA sequence target at Hvl inhibited Hvl expression. Scratch and matrigel invasion experiments showed that the migration and invasion of MDA-MB-231 cells were significantly attenuated when Hv1 was knocked down by siRNA targeting Hv1. Zymography experiment on matrix metalloproteinase indicated that the enzyme activities of MMP-2 markedly decreased.Conclusion:
Hv1 promoted the migration and invasion ability of breast cancer cells.
