原始语种摘要: With aging and Alzheimer's disease (AD), there is an increased sensitivity to stress along with declines in the memory-associated neurotrophin brain-derived neurotrophic factor in AD. We have replicated this aging phenotype in cultured neurons from aged mice despite being grown in the same environmental conditions as young neurons. This led us to hypothesize that age-related differences in epigenetic acetylation and methylation of histones are associated with age-related gene regulation. We cultured hippocampal/cortical neurons from the 3xTg-AD mouse model and from non-transgenic mice to quantify single cell acetylation and methylation levels across the life span. In non-transgenic neurons, H3 acetylation was unchanged with age, while H4 acetylation decreased with age of the donor....
