Silencing of the IKKε gene by siRNA inhibits invasiveness and growth of breast cancer cells.

ABSTRACT:

Introduction

IκB Kinase ε (IKKε) is a member of the IKK family which plays an important role in the activation of nuclear factor-κB (NF-κB). Overexpressed in over 30% of breast cancers, IKKε has been recently identified as a potential breast cancer oncogene. The purpose of this study is to examine the therapeutic potential of IKKε siRNA on human breast cancer cells.

Methods

Eight siRNAs targeting different regions of the IKKε mRNA were designed, and the silencing effect was screened by quantitative real time RT-PCR. The biological effects of synthetic siRNAs on human breast cancer cells were investigated by examining the cell proliferation, migration, invasion, focus formation, anchorage-independent growth(via soft agar assay), cell cycle arrest, apoptosis (via annexing bind
