Cardiac Aging in the Multi-Omics Era: High-Throughput Sequencing Insights

Area of Science:

• Cardiology
• Gerontology
• Molecular Biology

Background:

• Cardiovascular diseases (CVDs) are a major global cause of death.
• Aging significantly increases CVD risk and worsens prognosis.
• Understanding heart aging mechanisms is vital given rising life expectancy.

Purpose of the Study:

• To review the role of high-throughput multi-omics techniques in studying heart aging.
• To explore how these advanced methods reveal molecular and cellular processes in the aging heart.
• To guide the development of novel therapeutic targets for age-related cardiovascular conditions.

Main Methods:

• Review of existing literature on high-throughput multi-omics approaches.
• Analysis of how techniques like genomics, transcriptomics, proteomics, and metabolomics contribute to heart aging research.
• Examination of combined omics strategies for deeper insights.

Main Results:

• Traditional methods identified hallmarks of heart aging (e.g., oxidative stress, impaired autophagy, proteostasis loss, epigenetic changes).
• High-throughput multi-omics provide novel perspectives on molecular mechanisms and cellular processes.
• Integrated omics approaches yield robust findings on heart aging.

Conclusions:

• High-throughput multi-omics are transforming the study of heart aging.
• These techniques are essential for unraveling complex molecular pathways.
• Future research directions and prospects are promising for developing interventions against cardiovascular aging.
