Functional screening to identify senescence regulators in cancer

Area of Science:

• Cellular biology
• Cancer research
• Aging research

Background:

• Cellular senescence is a state of stable cell cycle arrest with diverse biological roles.
• Senescence can exert both pro-tumorigenic and anti-tumorigenic effects, complicating its study in cancer.
• The multifaceted nature of senescence arises from various triggers, cell types, and associated phenotypes.

Purpose of the Study:

• To highlight the pleiotropic and context-dependent roles of cellular senescence.
• To emphasize the need for comprehensive analysis of senescence phenotypes.
• To underscore the importance of advanced technologies in senescence research.

Main Methods:

• Review of recent studies characterizing cellular senescence.
• Integration of functional screens, in silico analysis, and omics characterizations.
• Application of state-of-the-art and emerging technologies.

Main Results:

• Cellular senescence plays complex, often opposing, roles in various biological processes, including cancer.
• Numerous factors influence senescence, leading to diverse outcomes.
• Current research employs multiple approaches to characterize senescence.

Conclusions:

• A deeper understanding of senescence's context-dependent effects is crucial.
• Advanced technologies are essential for unraveling senescence complexity.
• Harnessing or targeting senescence requires a comprehensive knowledge base for therapeutic strategies.
