Abstract
The World Health Organization has predicted new cancer rates to increase by 70 % within the next two decades. With rates expected to continue increasing in cancer incidence and mortality, chemoprevention and early diagnosis are the keys to decreasing cancer mortality. Chemoprevention is the use of natural or synthetic agents to inhibit, reverse, or prevent carcinogenesis. Studies have suggested there is a significant difference in cancer incidence among population groups with different lifestyle factors, especially diet. Phytochemicals or “nutraceuticals,” the substances present in fruits, vegetables, and plants, have beneficial effects targeting multiple key signaling molecules and perturbing the carcinogenesis process. Studies have demonstrated curcumin, resveratrol, 3,3′-diindolylmethane (DIM), and many others to hold inhibitory effects on cancer cells. There is overwhelming evidence that these nutraceuticals modulate key signaling pathways including cell cycle signaling and p53, transcription and inflammatory mediators such as NF-κB and PI3K/Akt/mTOR, and angiogenic pathways in cancer cells. Through regulation of cell signaling pathways, these dietary factors can induce cell arrest and apoptosis, and suppress proliferation and inflammation, resulting in inhibition of carcinogenesis. In this chapter, we review the effects of these nutraceuticals on some of the key signaling cellular and molecular pathways and highlight their roles as chemopreventive agents.
