It has been well established that NF-κB is constitutively activated in various cancers such as cancers of the breast, colon, liver, lung, pancreas etc. in response to carcinogens such as tobacco, alcohol, and exposure to radiation etc. Upregulation of NF-κB subsequently activates hundreds of pro-inflammatory gene products including TNF-α, IL-1, IL-6, chemokines, MMP-9, 5-LOX, VEGF, and COX-2 [20]. The gene discussed is TNF; the disease is breast cancer.
