NF-κB in carcinoma therapy and prevention

Background: NF-kappa B includes a family of signal-activated transcription factors that normally regulate responses to injury and infection but which are aberrantly activated in many carcinomas. Objective: To review the activation and role of NF-kappa B in pathogenesis and as a target for treatment and prevention in carcinoma. Methods: Evidence from experimental, epidemiological, preclinical studies and clinical trials cited in the literature are reviewed. Results/conclusion: Cumulative evidence implicates NF-kappa B in cell survival, inflammation, angiogenesis, spread and therapeutic resistance during tumor development, progression and metastasis of carcinomas. Non-specific natural and synthetic agents that inhibit NF-kappa B have demonstrated activity and safety in prevention or therapy. NF-kappa B-activating kinases and the proteasome are under investigation for targeted prevention and therapy of carcinoma.
