The normal aging process is a complex phenomenon associated with physiological alterations in the function of cells and organs over time. Although an attractive candidate for mediating transcriptional dysregulation, the contribution of epigenetic dysregulation to these progressive changes in cellular physiology remains unclear. In this study, we employed the genome‐wide HpaII tiny fragment enrichment by ligation‐mediated PCR assay to define patterns of cytosine methylation throughout the rat...
