Genomics, Genetics and Epigenetics for Animal Health and Longevity

Understanding environmental modelling of the genome is only just beginning, as science learns to integrate genomics (gene expression), with genetics (predisposition) and epigenetics (programming or imprinting). Epigenetics studies how the genome is programmed for health and longevity; provides insights into metabolic regulation; involves mechanisms of development, parental gene imprinting, and metabolic programming beyond genetic control; and modulates gene expression throughout life. Genetic and epigenetic markers define predisposition and susceptibility to disease, and requires study of the epigenome, which is tissue and stage-of-life dependent, and varies markedly between individuals and species. Epigenetics also encompasses the study of how external influences, like diet, affect the activity and expression of genes in the DNA. Thus, epigenetics encompasses understanding and achieving the potential of nutrition to maintain health and prevent disease. Genes make up just two percent of the genome. Humans, cats and dogs have about 22,000 genes. The remainder of the genome (98%) holds the vast majority of information that programs the genes and controls gene expression. The epigenome controls inheritance, and epigenetics is the new science that focuses on changes in gene activity that do not result in parallel changes in DNA sequences or structure. It results in molecular modification of DNA by methylation, production of modified histones (proteins), and RNA interference (RNAi). Importantly, nutrition modulates gene expression through the genome and metabolism in combination with epigenetic factors.
