Genetic background can affect adaptations to aging
A study conducted by a psychologist from the University of California at Riverside suggests that our ability to adapt to late-life aging may be genetically determined.
The findings of the research published in Aging Cell have implications for epigenetic factors and aging. The epigenesis process is where chemicals are attached to DNA and control its activity. The epigenetic changes that can be passed down to children may play a critical role in accelerating aging and the declines of cognitive and physical function associated with aging. The epigenetic changes that alter gene expression can be caused by a variety of biological processes. One such process was the one studied by researchers: DNA methylation.
DNA methylation is the addition of methyl groups to DNA molecules. DNA is made up of four nucleotides, A, T G and C. DNA methylation takes place at the C bases in eukaryotic genomes. The changes in DNA methylation are strongly correlated with aging.
