Senescence in cancer

Area of Science:

• Cellular and Molecular Biology
• Oncology
• Aging Research

Background:

• Cellular senescence is a stable cell-cycle arrest triggered by stress, acting as a tumor suppressor.
• Accumulated senescent cells are linked to age-related diseases and cancer progression.
• Senescence has a dual role in cancer, potentially inhibiting or promoting tumor development via the senescence-associated secretory phenotype (SASP).

Purpose of the Study:

• To review the multifaceted role of cellular senescence in cancer.
• To explore the interactions between senescent cells, tumor cells, stroma, and the immune system.
• To discuss therapeutic strategies targeting senescent cells and AI-driven detection methods.

Main Methods:

• Literature review of cellular senescence in the context of cancer.
• Analysis of the dual role of senescence in tumor initiation and progression.
• Exploration of therapeutic interventions and artificial intelligence (AI) applications.

Main Results:

• Senescence can suppress tumors by arresting damaged cell proliferation.
• The SASP secreted by senescent cells can promote tumor growth and immune evasion.
• Senescence outcomes in cancer are highly context-dependent, influenced by the tumor microenvironment.

Conclusions:

• Cellular senescence presents a complex, context-dependent role in cancer biology.
• Targeting senescent cells offers potential therapeutic avenues for cancer treatment.
• AI holds promise for improving the detection and characterization of senescent cells in oncology.
