Crosstalk between P53 and DNA damage response in ageing

Area of Science:

• Genetics and Molecular Biology
• Cellular Aging
• Genomic Stability

Background:

• Aging is characterized by reduced physiological capacity and increased mortality, driven by accumulated cellular damage.
• The DNA damage response (DDR) pathway is crucial for maintaining genomic integrity during the aging process.
• Dysfunctional DDR signaling contributes to various age-related pathologies.

Purpose of the Study:

• To review the intricate interactions between p53 and DDR signaling.
• To elucidate the role of p53-DDR pathways in the aging process.
• To understand the contribution of these pathways to age-related functional decline.

Main Methods:

• Literature review of studies on p53, DDR, and aging.
• Analysis of signaling pathways involved in genomic maintenance.
• Synthesis of current understanding of p53's role in DDR and aging.

Main Results:

• p53 acts as a central component of the DDR pathway.
• The integrity and function of DDR signaling, particularly involving p53, are critical for healthy aging.
• Accumulation of DNA damage due to p53 dysfunction accelerates aging and disease.

Conclusions:

• The p53-mediated DNA damage response is a key regulator of the aging process.
• Maintaining functional p53 and DDR signaling is vital for mitigating age-related decline and diseases.
• Further research into p53-DDR interactions may reveal therapeutic targets for aging.
