Cellular Senescence: Mechanisms and Therapeutic Potential

Area of Science:

• Cellular and Molecular Biology
• Gerontology
• Biomedical Sciences

Background:

• Cellular senescence is a stress-induced, stable cell cycle arrest with diverse physiological and pathological roles.
• Key features include the senescence-associated secretory phenotype (SASP), cell cycle arrest, and chromatin remodeling.
• Senescence can be detrimental in aging and disease or beneficial in developmental processes.

Purpose of the Study:

• To provide a comprehensive overview of the current understanding of cellular senescence.
• To discuss the implications of senescence in various biological processes and diseases.
• To highlight the translational potential of senotherapy and pro-senescence therapies.

Main Methods:

• This review synthesizes existing literature on cellular senescence.
• It analyzes the characteristics, functions, and pathologies associated with senescent cells.
• The review discusses current and emerging therapeutic strategies targeting senescence.

Main Results:

• Cellular senescence is a complex process with dual roles in health and disease.
• Persistent senescence contributes to aging and pathologies like cancer and atherosclerosis.
• Transient senescence plays roles in beneficial processes such as embryonic development.

Conclusions:

• Cellular senescence is a critical biological process with significant implications for human health and disease.
• Senotherapy and pro-senescence strategies show promise for treating age-related diseases and cancer.
• Further research is needed to identify unique biomarkers for senescent cells to advance therapeutic development.
