Targeting DNA damage in ageing: towards supercharging DNA repair.

Area of Science:

• Gerontology and Molecular Biology
• Genetics and Epigenetics
• Cellular and Molecular Medicine

Background:

• Ageing is the primary risk factor for major human diseases like cancer, diabetes, and cardiovascular conditions.
• Interventions in model organisms have extended lifespan and healthspan, but their causal link to ageing mechanisms remains unclear.
• Somatic DNA damage is a significant causal mechanism of ageing, impairing cellular functions and leading to senescence, apoptosis, and mutations.

Purpose of the Study:

• To review advances in targeting DNA damage consequences and enhancing DNA repair to mitigate ageing.
• To discuss pharmacological approaches for mitigating DNA damage effects.
• To explore strategies for delaying ageing, preventing cancer, and reducing age-related diseases.

Main Methods:

• Review of scientific literature on ageing, DNA damage, and DNA repair mechanisms.
• Analysis of genetic and pharmacological interventions in model organisms.
• Discussion of emerging concepts and therapeutic strategies.

Main Results:

• Evidence strongly implicates DNA damage as a causal mechanism in the ageing process.
• Interventions targeting DNA damage consequences and repair capacity show promise in model organisms.
• Pharmacological mitigation of DNA damage effects is a developing strategy.

Conclusions:

• Targeting DNA damage and enhancing repair are rational strategies to combat ageing and age-related diseases.
• Pharmacological interventions hold potential for delaying ageing and preventing degenerative conditions.
• Further research is needed to translate these findings into human therapies.
