Epigenetic alterations aging

WebRecent research efforts provided compelling evidence of genome-wide DNA methylation alterations in aging and age-related disease. It is currently well established that DNA methylation biomarkers can determine biological age of any tissue across the entire human lifespan, even during development. There is growing evidence suggesting epigenetic … WebThe Aging Process. The problem is that during aging the epigenome becomes increasingly dysregulated. Liver-specific genes are switched on in brain cells, stomach genes are switched on in muscle cells, and so on. Genes that need to be turned off are turned on (like cancer-promoting genes), and genes that need to be turned on are switched off ...
