The process of aging is determined by various genetic and environmental factors. Aging is associated with increased oxidative stress that alters cellular chromatin structure, DNA methylation with histone modifications. These epigenetic alterations lead to nuclear changes associated with mitochondrial apoptosis that is a major defect in the global chronic disease epidemic (1). The variability in longevity between individuals in different communities implicate various nutritional and environmental factors involved in transcriptional dysregulation that lead to cell damage that accumulates with age and contributes to mitophagy, insulin resistance and programmed cell death. The absence or malfunction of a gene (2) necessary for transcriptional regulation of gene expression, DNA repair and telomere maintenance in neurons has become essential with relevance to neurodegeneration that determines aging and lifespan.
