The role of nutrition in cancer from the perspective of Epigenetic

Epigenetics refers to the processes which lead to modification in phenotype or gene expression and function without altering the DNA structure. These Changes may be existing in several generations without any modification in DNA sequences. Epigenetic modifications are persistent changes in gene expression which are imposed to daughter cells due cell division. These Changes are not due to changes in bases sequences in DNA structure. Epigenetic modification is considered as protective or risk factors for some diseases such as cancers. Environmental and nutritional factors can leads to epigenetic modifications. Recently, the role of some foods and micronutrients in epigenetic modifications are noted. This article reviews new articles on association of nutrition, cancer and epigenetics.
