High IKKα expression is associated with reduced time to recurrence and cancer specific survival in oestrogen receptor (ER)-positive breast cancer

The aim of our study was to examine the relationship between tumour IKKα expression and breast cancer recurrence and survival. Immunohistochemistry was employed in a discovery and a validation tissue microarray to assess the association of tumour IKKα expression and clinico‐pathological characteristics. After siRNA‐mediated silencing of IKKα, cell viability and apoptosis were assessed in MCF7 and MDA‐MB‐231 breast cancer cells. In both the...
