Over time, aging is marked by a progressive loss of physiological integrity and function. Aging epigenetics refers to the changes in gene expression that occur naturally during a lifespan of the organism without changing the DNA sequence. Several enzymes are involved in chromatin epigenetics, which result in changes in DNA methylation and histone methylation/acetylation processes.
