DNA and histone modifications are involved in the epigenetic programming and
organization of the genome. Epigenetic refers to a variety of processes that have heritable …

DNA hydroxymethylation A hydroxymethyl group located at the 50 position on a cytosine.
Considered a mark of active demethylation catalyzed by the enzyme ten-eleven-transferase …

Methylation is a major regulator of mammalian genome function in vivo. The methylation of
DNA on cytosine residues is a critical component of the host genome defense pathway …

Publisher Summary This chapter focuses on the interplay between diet and DNA
methylation patterns and how dietary factors may alter the DNA methylation status and …

Epigenetics is a wide term representing molecular processes leading to modification of gene
expression without bringing any DNA base sequence alterations. Major epigenetic …

Key Points 1. Diet and dietary factors are important contributing factors to health and
disease. Since an inappropriate diet may contribute significantly to the causation of chronic …

DNA methylation is a biological process that results in the addition of methyl groups to DNA.
Methyl groups are “one-carbon” chemical groups and their covalent attachment to certain …

Cells of a multicellular organism are genetically homogeneous but structurally and
functionally heterogeneous owing to the differential expression of genes. Many of these …

The dietary intake of essential nutrients and bioactive food compounds is a process that
occurs on a daily basis for the entire life span. Therefore, your diet has a great potential to …

Epigenetics is the study of the regulation of gene activity that is not dependent on nucleotide
sequence; this may include heritable changes in gene activity and expression, but also long …
