What is the Origin of Longevity Pathway Interruption?

This term is rooted in the burgeoning field of geroscience, which studies the molecular mechanisms of aging and longevity. The "pathways" refer to conserved metabolic and genetic networks identified across species that, when modulated, can extend lifespan. The concept of "interruption" emphasizes that aging is not merely a passive process but an active failure of protective and regenerative mechanisms.

What is the Mechanism of Longevity Pathway Interruption?

Interruption often occurs due to chronic over-nutrition, sedentary lifestyle, or persistent inflammation, which act as negative modulators. For instance, chronic hyperinsulinemia can excessively activate the mTOR pathway, shifting the cellular state toward growth and storage rather than the essential repair and autophagy functions mediated by AMPK and sirtuins. This continuous activation of pro-growth signaling at the expense of maintenance pathways fundamentally compromises the cell's ability to self-correct and survive long-term.

Longevity Pathway Interruption

Meaning

Longevity Pathway Interruption describes the detrimental functional blockade or downregulation of key intracellular signaling cascades that are genetically and biochemically linked to cellular repair, stress resistance, and lifespan extension. These pathways include sirtuins, AMPK, and mTOR, which act as master regulators of metabolic health and cellular maintenance. An interruption in these processes accelerates cellular senescence and contributes directly to the phenotypic manifestations of biological aging.
