[Cellular senescence and age-related diseases]

Area of Science:

• Gerontology
• Cell Biology
• Molecular Biology

Background:

• Cellular senescence is a stable cell cycle arrest.
• Cellular proliferation capacity correlates with animal lifespan.
• Senescence plays a key role in organismal aging and age-related diseases.

Purpose of the Study:

• To review recent advances in understanding senescence.
• To explore mechanisms of senescence induction and maintenance.
• To discuss the senescence-associated secretory phenotype (SASP).

Main Methods:

• Literature review of cellular senescence.
• Analysis of the link between cellular proliferation and organismal aging.
• Examination of senescence-associated secretory phenotypes (SASP).

Main Results:

• Cellular senescence is linked to organismal aging and lifespan.
• Senescent cells contribute to age-related disorders like atherosclerosis, type II diabetes, and Alzheimer's disease.
• Clearance of senescent cells can delay age-associated disorders and extend healthspan.

Conclusions:

• Cellular senescence is a fundamental process in aging.
• Understanding senescence mechanisms and SASP is crucial for targeting age-related diseases.
• Targeting senescent cells offers a potential therapeutic strategy for aging and related conditions.
