Role of DNA damage in cardiovascular disease

Area of Science:

• Genetics
• Molecular Biology
• Cardiology

Background:

• Progeroid syndromes, like Werner syndrome, manifest as premature aging with early-onset atherosclerotic cardiovascular disease (CVD).
• Genetic defects in DNA damage response (DDR) pathways are implicated in most progeroid syndromes, impacting genome stability.
• Therapeutic radiation, a potent genotoxic agent, is increasingly linked to cardiovascular complications.

Purpose of the Study:

• To elucidate the role of DNA damage and DDR in the pathogenesis of atherosclerotic CVD.
• To review molecular insights into progeroid syndromes associated with CVD.
• To analyze radiation-induced CVD pathology and epidemiology.

Main Methods:

• Literature review of genetic defects in progeroid syndromes.
• Analysis of DNA damage and response mechanisms.
• Review of pathological and epidemiological data on radiation-induced CVD.

Main Results:

• Progeroid syndromes involve genetic defects in DNA damage response pathways.
• Ionizing radiation causes DNA damage and is associated with cardiovascular complications.
• Atherosclerotic CVD pathogenesis may involve DNA damage and DDR.

Conclusions:

• DNA damage and its response are critical factors in premature aging syndromes and cardiovascular disease.
• Further research into DDR mechanisms could offer novel therapeutic strategies for CVD.
