Abstract |
Ovarian cancer is one of the leading causes of female death and the development of novel therapeutic approaches is urgently required. Nuclear factor-κB (NF-κB) is constitutively activated in several types of cancer including ovarian cancer and is known to support the survival of cancer cells. However, molecular mechanisms of persistent activation of NF-κB in ovarian cancer remain largely unknown. We report here that, in addition to the previously reported canonical activation, NF-κB is activated through the noncanonical pathway in ovarian cancer cells. RNA interference-mediated silencing of NF-κB inducing kinase (NIK), a central regulator of the noncanonical pathway, reduced the NF-κB2/p52 DNA binding activity and NF-κB-dependent reporter gene expression as well as NF-κB target gene expression. Notably, anchorage-dependent and -independent cell growth was impaired in NIK-depleted cells. Depletion of NIK also suppressed tumor formation in the nude mouse xenograft assay. These results indicate that NIK plays a key role in constitutive NF-κB activation and the progression of ovarian cancer cells and suggest that NIK represents an attractive therapeutic target for ovarian cancer.
