What is the Origin of Pro-Survival Networks?

This concept is a cornerstone of cell biology, oncology, and geroscience, arising from the detailed study of how cells decide between life and death under duress. In the context of aging, the focus shifts to supporting these networks to extend the functional lifespan of healthy, non-senescent cells. The term highlights the active, defensive nature of cellular self-preservation mechanisms.

What is the Mechanism of Pro-Survival Networks?

These networks function through key signaling molecules, such as the PI3K/Akt/mTOR pathway, and the activity of various anti-apoptotic protein families that actively suppress the initiation of the caspase cascade. Hormones, particularly Growth Hormone and its downstream effector, Insulin-like Growth Factor 1 (IGF-1), often interface with these networks to promote anabolic signaling and tissue repair. The proper balance of pro-survival and pro-death signals is essential for maintaining cellular quality control.

Pro-Survival Networks

Meaning

Pro-Survival Networks are the complex, interconnected molecular pathways within a cell that are activated to actively promote cell viability, resist programmed cell death (apoptosis), facilitate DNA repair, and maintain the integrity of cellular structures in the face of various physiological stressors. These networks are fundamental to the resilience and regenerative capacity of all tissues, including endocrine glands. Their robust function is key to longevity.
