Autophagy inducers in cancer

Area of Science:

• Cell Biology
• Oncology
• Biochemistry

Background:

• Autophagy is a fundamental cellular process for degrading and recycling cellular components via autophagosomes and lysosomes.
• This physiological process is implicated in the pathophysiology of numerous diseases, including cancer.
• Autophagy exhibits dual roles in tumor biology, either promoting cancer cell survival (protective) or inducing cell death (cytotoxic).

Purpose of the Study:

• To review the potential of autophagy inducers in cancer prevention and therapy.
• To explore the dichotomy of autophagy's roles in cancer biology and its therapeutic implications.
• To discuss identified synthetic and natural compounds that modulate autophagy.

Main Methods:

• Literature review focusing on the dual roles of autophagy in cancer.
• Analysis of existing research on autophagy inducers, both synthetic and natural.
• Discussion of the challenges and future directions in clinical applications of autophagy modulation.

Main Results:

• Autophagy activation can be either protective, aiding cancer cell survival, or cytotoxic, leading to cancer cell death.
• Tissue-dependency and specific treatment timing are crucial for effective autophagy modulation in cancer.
• Several synthetic and natural compounds show promise in regulating autophagy, but their clinical utility requires further investigation.

Conclusions:

• A deeper understanding of autophagy's dual roles is essential for developing targeted cancer therapies.
• Developing clinically relevant autophagy inducers necessitates careful consideration of their context-dependent effects.
• Further clinical studies are required to fully elucidate the therapeutic landscape of autophagy modulation in cancer treatment.
