Molecular Biology Aging

Meaning

Molecular biology aging is the study of the fundamental cellular and subcellular processes that progressively lead to a decline in physiological function and an increased susceptibility to disease over time. This discipline focuses on the nine recognized hallmarks of aging, including genomic instability, telomere attrition, mitochondrial dysfunction, and altered intercellular communication. Understanding these core molecular mechanisms is essential for developing interventions that target the root causes of senescence, aiming to extend healthspan by modulating the intrinsic rate of biological decay.
