The study also indirectly indicates the role of theenvironment on aging. Our lifestyles (air quality, nutrition, sporting activity, etc.) would represent up to one third changes in gene expression with age.
“Almost all common human diseases are diseases of aging : Alzheimer’s, tumors, heart disease, diabetes. All of these diseases increase in prevalence with age.says Peter Sudmant, assistant professor of integrative biology at UC Berkeley and lead author of the study.
“What our study shows is that as we get older, genes matter less for gene expression. And so, perhaps, we need to be careful to this when we try to identify the causes of these diseases of aging “concludes.
