The nuclear factor-kappa B pathway and response to treatment in breast cancer

초록

The nuclear factor-kappa B (NF-kappa B) pathway is known to contribute to critical signaling in cancer biology, including breast cancer, through promotion of proliferation, angiogenesis, metastasis, tumor progression, inflammation and cell survival. In this review, in vivo and in vitro studies of the NF-kappa B pathway in breast cancer are discussed, focusing on DNA damage and the epithelial-mesenchymal transition associated with breast cancer stem cell properties. The relationships between NF-kappa B signaling and conventional cancer treatments in terms of response to chemo-and radiotherapy will also be discussed. Then contribution and involvement of immune system in the NF-kappa B pathway will be covered. Furthermore, the future perspective of NF-kappa B targeting as an innovative strategy to overcome refractory breast cancer, including recent updates on out-receptor activator of NF-kappa B (RANKing), will be covered.
