Background
Kinesin family member 26B (KIF26B) plays a key role in the development and progression of many human cancers. However, the role and underlying mechanisms of KIF26B in breast cancer cells remain unknown. Materials and
Conclusion
Our data indicate that KIF26B plays a pivotal role in tumor growth and metastasis in breast cancer cells and may be a potential therapeutic target for treating breast cancer.
Methods
In this study, we inhibited the expression of KIF26B in MDA-MB-231 and MCF-7 cells using lentivirus-delivered shRNA.
Results
Lentivirus-mediated KIF26B knockdown significantly suppressed cell proliferation, colony formation, migration, and invasion. Furthermore, cell cycle analyses revealed that the percentage of cells in the G0/G1 phase was significantly increased in KIF26B knockdown cells. Moreover, the knockdown of KIF26B significantly promoted cell apoptosis via the upregulation of cleaved caspase-3 and Bax.
