Targeting Inflammatory Pathways by Flavonoids for Prevention and Treatment of Cancer

Abstract

Observational studies have suggested that lifestyle risk factors such as tobacco, alcohol, high-fat diet, radiation, and infections can cause cancer and that a diet consisting of fruits and vegetables can prevent cancer. Evidence from our laboratory and others suggests that agents either causing or preventing cancer are linked through the regulation of inflammatory pathways. Genes regulated by the transcription factor NF-κB have been shown to mediate inflammation, cellular transformation, tumor cell survival, proliferation, invasion, angiogenesis, and metastasis. Whereas various lifestyle risk factors have been found to activate NF-κB and NF-κB-regulated gene products, flavonoids derived from fruits and vegetables have been found to suppress this pathway. The present review describes various flavones, flavanones, flavonols, isoflavones, anthocyanins, and chalcones derived from fruits, vegetables, legumes, spices, and nuts that can suppress the proinflammatory cell signaling pathways and thus can prevent and even treat the cancer.

Key words

cancer - inflammation - flavonoids - NF‐κB - fruits - vegetables
