| Epigenetics is the study of the change of gene expression, or even cellular phenotype, without alterations to the underlying DNA sequence. The discipline creates a record of how environmental factors, lifestyle choices, and developmental processes influence the activity of genes and hence lead to a myriad of biological outcomes. Epigenetic modifications-which are differentiated from genetic mutations-do not alter the DNA sequence itself but affect which genes are activated or deactivated and thus states of gene expression. Such mechanisms of epigenetic regulation include DNA methylation and histone modification through non-coding RNA molecules. DNA methylation involves the addition of methyl groups to DNA that often ends in gene repression. Histone modification represents an alteration in chemical makeup, which envelopes histone proteins-around which DNA winds, implicating access to gene and expression. Regulation of gene expression goes hand in hand with non-coding RNAs through involvement in determining RNA stability and translation. Epigenetics is highly important in the explanation of development, cellular differentiation, and disease. It helps explain why identical twins who share their DNA could have traits or health conditions different from one another because of differences in exposures. Epigenetic changes are involved in many diseases, such as cancers, cardiovascular diseases, neurological disorders, among others. Epigenetic studies have provided us with really strong evidence regarding gene-environment interactivity, with great promulgation in personalized medicine and therapeutic strategy. Targeting epigenetic modification targets would provide the new avenue for disease treatment; lifestyle and environmental influences on health and disease are also known:. |
