ABSTRACT
Objective:
To observe the effect of low-expression or over-expression of NUP88 gene on the proliferation and invasion ability of breast cancer cell line BT-20.Methods:
NUP88 recombinant adenovirus expression vector and NUP88 RNAi adenovirus vector were transfected into breast cancer BT-20 cells to obtain BT-20 cells over-expressing NUP88 and BT-20 cells lower-expressing NUP88 and then detected the expression of NUP88 mRNA and NUP88 protein.After that,the apoptosis of BT-20 cells was detected by flow cytometry and the invasion and metastasis of BT-20 cells were detected by Transwell invasion assay.The expression of apoptosis protein and invasion and metastasis proteins were detected by Western blot.Results:
BT-20 cell with the over expression levels of NUP88 mRNA and NUP88 protein and BT-20 cell with the low expression levels of NUP88 mRNA and NUP88 protein were structured.The over-expression of NUP88 gene led to proliferation rate and the number of invasive cells were significantly higher than BT-20 cells,apoptosis cells were significantly lower than BT-20 cells(P<0.05).However,the low-expression of NUP88 gene led to proliferation rate and the number of invasive cells were significantly lower than BT-20 cells,apoptosis cells was significantly higher than BT-20 cells(P<0.05).The over-expression of NUP88 gene led to Bcl-2 and β-catenin level were significantly higher than that of BT-20 cells,and Bax and E-cadherin level were significantly lower than that of BT-20 cells(P<0.05).However,the low-expression of NUP88 gene led to Bcl-2 and β-catenin level were significantly lower than that of BT-20 cells,and Bax and E-cadherin level were significantly higher than that of BT-20 cells(P<0.05).Conclusion:
NUP88 gene regulates the proliferation and invasion and migration ability of breast cancer cells by regulating the expression of Bax,Bcl-2,E-cadherin and β-catenin.It has an important significance in the target treatment of breast cancer.
