Background
Nuclear factor‐κB (NF‐κB), a transcription factor known to modulate expression of factors involved in inflammation, immunity, proliferation, and apoptosis, is constitutively activated and plays a role in pathogenesis and therapeutic resistance in head and neck squamous cell carcinoma (HNSCC). Understanding the molecular alterations leading to aberrant NF‐κB activation in HNSCC may direct investigators to novel therapeutic targets.
Methods
Results of laboratory and clinical studies are reviewed.
Results
The structure, function, and activation of NF‐κB, products of NF‐κB target genes and their role in HNSCC oncogenesis, and current NF‐κB modulating interventions are described.
Conclusions
Aberrant NF‐κB activation contributes to the expression of oncogenes and the malignant phenotype observed in HNSCC. NF‐κB, along with providing a link between cancer and inflammation, may serve as an appropriate therapeutic target to inhibit tumor growth and sensitize cancer cells to established cytotoxic anticancer therapies. © 2007 Wiley Periodicals, Inc.
