Epigenetics is the study of heritable changes in gene expression that occur without a change in DNA sequence. Cancer is a multistep process derived from combinational crosstalk between genetic alterations and epigenetic influences through various environmental factors. The observation that epigenetic changes are reversible makes them an attractive target for cancer prevention. Until recently, there have been difficulties studying epigenetic mechanisms in interactions between dietary factors and environmental toxicants. The development of the field of cancer epigenetics during the past decade has been advanced rapidly by genome-wide technologies — which initially employed microarrays but increasingly are using high-throughput sequencing — which helped to improve the quality of the analysis, increase the capacity of sample throughput, and reduce the cost of assays. It is particularly true for applications of cancer epigenetics in epidemiologic studies that examine the relationship among diet, epigenetics, and cancer because of the issues of tissue heterogeneity, the often limiting amount of DNA samples, and the significant cost of the analyses. This review offers an overview of the state of the science in nutrition, environmental toxicants, epigenetics, and cancer to stimulate further exploration of this important and developing area of science. Additional epidemiologic research is needed to clarify the relationship between these complex epigenetic mechanisms and cancer. Cancer represents a group of diseases initiated and driven largely by heritable genetic aberrations resulting from exposure to endogenous and environmental agents Loeb and Harris, ; Pogribny et al. Therefore, the general approach for elucidating key events in cancer development has focused on identifying genetic aberrations associated with carcinogenesis. However, the presence of genetic lesions alone is not sufficient for tumor formation. Tumor formation results mainly from the inability of cells to maintain and control accurate expression of genetic information.

Endocrine disruptors are compounds found in the environment that mimic the actions of hormones. Prevention of chemical carcinogenesis by vitamin A and its synthetic analogs retinoids. Despite these challenges, research on dietary phytochemicals continues to emerge and will offer new epigenetic targets and promising agents with more opportunities for prevention, and perhaps personalized therapy of cancer in the near future. These findings suggest that PEITC treatment could be used to decrease tumor aggressiveness and prevent metastasis.
