Systems Biology Aging applies a holistic, multi-disciplinary approach to understand aging as a complex biological process arising from the emergent properties of interacting biological networks, rather than solely from individual molecular or cellular defects.
Context
Systems Biology Aging integrates data from genomics, proteomics, metabolomics, and other high-throughput technologies to model the interconnected biological pathways and networks that change with age. It examines how these systems interact and contribute to the aging phenotype.
Significance
From a clinical perspective, Systems Biology Aging offers a more comprehensive understanding of the aging process, paving the way for novel interventions that target multiple aging pathways simultaneously, aiming to improve healthspan and treat age-related diseases more effectively.
Mechanism
Aging is viewed as a result of accumulating molecular damage, cellular dysfunction, and altered intercellular communication across various interconnected biological systems, including metabolism, epigenetics, stem cell exhaustion, and altered intercellular communication. Systems Biology Aging aims to map these interactions.
Application
Systems Biology Aging is used to identify key aging biomarkers, discover potential geroprotective compounds by analyzing their effects on multiple aging pathways, and develop personalized strategies for healthy aging based on an individual’s unique biological network profile.
Metric
Metrics in Systems Biology Aging are diverse and include omics data (genomic, transcriptomic, proteomic, metabolomic), epigenetic clocks, telomere length, senescent cell burden, and functional measures of organ system performance across the lifespan.
Risk
A lack of comprehensive understanding of aging as a systems-level phenomenon can lead to fragmented research and therapeutic approaches that address symptoms rather than root causes, potentially missing opportunities for effective interventions to promote longevity and healthspan.
