Exploring the Pathways: How Does Senescence Occur?

Did you know that normal human cells have a finite capacity to divide? This limit leads to a state called cellular senescence, and understanding exactly how does senescence occur is key to comprehending the fundamental processes of aging and age-related diseases. The process is a complex interplay of molecular events that halt cell division in response to stress.

What are the critical roles of p53 in senescence and aging?

Cellular senescence, a state of irreversible cell cycle arrest, is a powerful anti-tumor mechanism but also a driver of aging. The tumor suppressor protein p53 is a central regulator of cellular senescence and aging, exhibiting a multifaceted and sometimes paradoxical influence on lifespan. Its critical roles are context-dependent, shifting between beneficial and detrimental effects depending on the level and duration of its activation.
