DNA Methylation is as Active Mark of Aging and Cognitive Impairment
Aging and age-related cognitive decline have been reported to be associated to transcriptomic alterations related to neural activity, synaptic plasticity and inflammation in specific brain regions, including the hippocampus and the medial prefrontal cortex (mPFC).1-4 Furthermore, previous epigenetic studies indicate that DNA methylation in the hippocampus is linked to cognitive …
