Ageing is a sophisticated process, accompanied by reduction in general physiological capacity and increase in mortality and death, stemming from damage accumulation over time. Various signaling pathways are known to be involved in the functional decrease in various organs in ageing humans. One of the most prominent pathways is DNA damage response (DDR), which is responsible for maintenance of the genomic integrity and stability. Insufficient or dysfunctional DDR signaling and the subsequent accumulation of potential DNA lesions are associated with the initiation/progression of various human pathologies including ageing. As a tumor suppressor gene, with critical functions in the ageing process, p53 is considered as a DDR centerpiece. In this review, we aim to discuss the interactions between p53 and DDR signaling and their contributions in ageing.
