In conclusion, this study suggests that epigenetic age acceleration is significantly associated with lung function in women older than 50 years. We hypothesised that this could be due to menopause. However, we have observed that menopause has minimal effect and therefore there is possibility of other unknown physiological factors at older age in females mediating the epigenetic age acceleration effect on lung function. While, it is still unknown what exactly epigenetic aging from DNA methylation measures, this study suggests it can be utilised as one of the important factors to assess women's lung health in old age. DNA methylation-based lifespan predictors, such as DNAm GrimAge and plasma protein levels are strongly associated with lung function. Therefore this study suggests that these can be utilised as important factors to assess lung health in adults. Astrocyte Senescence Causes Death of Neurons in Cell Culture https://www.fightaging.org/archives/2020/01/astrocyte-senescence-causes-death-of-neurons-in-cell-culture/ With the caveat that the behavior of cells in culture is not necessarily all that relevant to their behavior amidst the full complexities of living tissue, this study is an interesting initial exploration of the ways in which the cellular senescence of supporting cells in the brain might contribute to the progression of neurodegeneration. Senescent cells secrete a potent mix of inflammatory and other signaling; while they serve a useful pur...
