Autophagy in cancer metastasis

Area of Science:

• Cell Biology
• Oncology
• Molecular Biology

Background:

• Autophagy is a fundamental cellular process involved in stress response and survival.
• Cancer metastasis remains a significant challenge with limited therapeutic options.
• Emerging evidence suggests autophagy's involvement in various stages of cancer spread.

Purpose of the Study:

• To review the multifaceted roles of autophagy in cancer metastasis.
• To highlight autophagy's impact on key metastatic processes.
• To discuss the therapeutic implications of targeting autophagy in metastatic cancer.

Main Methods:

• Literature review of studies on autophagy and cancer metastasis.
• Analysis of data from human cancers, genetically engineered mouse models, and experimental metastasis models.
• Synthesis of findings on autophagy's modulation of metastatic cascade phases.

Main Results:

• Autophagy is induced during cancer metastasis progression in various human cancers.
• Autophagy influences tumor cell motility, invasion, and cancer stem cell properties.
• It impacts anoikis resistance, epithelial-to-mesenchymal transition, dormancy, immune evasion, and pre-metastatic niche formation.

Conclusions:

• Autophagy is integral to multiple steps of the metastatic cascade.
• Targeting autophagy presents a promising avenue for managing metastatic cancer.
• Further research into autophagy's role can inform novel disease management strategies.
