Aging and Protein Kinases


PROTEIN KINASE-MEDIATED DECISIONS BETWEEN LIFE AND DEATH, vol.1275, pp.35-69, 2021 (SCI-Expanded) identifier identifier


Recently, aging has been tried to be explained with large numbers of theories, but none of them can elucidate the changes occurring in the aging process alone. A unified theory encompassing the mechanisms of genetic factors and repair systems in aging is becoming increasingly required. Almost 37 protein kinases contribute to all processes of aging and senescence. Furthermore, these kinases not only regulate the large number of metabolic pathways related to aging processes, but also control these pathways through 12 checkpoints. Thus, in this chapter, the metabolic targets of protein kinases signal transduction pathways were discussed in terms of the aging perspective under five headings, which are the indispensable stages of the aging process. Although the most popular classical aging theories have been stated as DNA damage theory, mitochondrial theory, free radical theory, and telomere theory, it was concluded that the aging process is controlled by protein kinases regardless of the different theories.
