摘要
Aquaporins (AQPs), proteinaceous water channels, have been proposed as mediators of tumour development and progression. However, the role of aquaporin 4 (AQP4), a member of the AQP family, in breast cancer has not been distinctly evaluated. The aim of the present study was to examine the effect of AQP4 down-regulation on proliferation, migration and invasion in human breast cancer. To determine this effect, siRNA interference was used to knock down its expression in T47D and MCF-7 cell lines. Down-regulation of AQP4 resulted in increased expression of E-cadherin along with an inhibitory effect on the proliferation, migration and invasion in breast cancer cells. In addition, AQP4 regulation of cell proliferation could be related with the ERK/E-cadherin pathway. In conclusion, the present data have suggested that down-regulation of AQP4 inhibits breast cancer cell proliferation, migration and invasion.
