ABSTRACT
AIM:
To observe the effect on NF-?B pathway and cell motility in breast cancer cell lines after transfection of dominant negative I?B? plasmid.METHODS:
After stable transfection of mutant I?B? plasmid into highly metastatic breast cancer lines MDA-MB-231 and MDA-MB-435,we detected NF-?B binding activity by EMSA,cell growth ability by cell growth curve,colony forming test,and cell motility by millicell-PCF chamber.RESULTS:
Constitutive activities in MDA-MB-231 and MDA-MB-435 were observed.Stable transfection of a dominant negative Ⅰ?B? resulted in downregulation of NF-?B binding activity,thus inhibited cell mobility without significant effect on cell growth.CONCLUSION:
Cell migration ability is inhibited in highly invasive breast cancer cells by inhibition of NF-?B pathway in vitro.
