Targeting Cytoprotective Autophagy to Enhance Anticancer Therapies

Area of Science:

• Cell Biology
• Oncology
• Molecular Medicine

Background:

• Autophagy is a fundamental cellular process crucial for maintaining cellular homeostasis.
• Dysregulation of autophagy is implicated in various pathologies, notably cancer.
• Autophagy's role in cancer is complex, acting as both a tumor suppressor and a promoter of tumor survival.

Purpose of the Study:

• To review the current understanding of autophagy's impact on cancer therapies.
• To explore the therapeutic potential of modulating autophagy in cancer treatment.
• To discuss challenges in developing autophagy-targeting drugs for clinical use.

Main Methods:

• Literature review of experimental and clinical evidence.
• Analysis of molecular mechanisms underlying autophagy in cancer.
• Examination of preclinical and clinical studies on autophagy modulators.

Main Results:

• Autophagy is a well-established cytoprotective mechanism in cancer, contributing to resistance against chemotherapy, radiotherapy, targeted therapy, and immunotherapy.
• Genetic and pharmacological modulation of autophagy pathways significantly impacts the efficacy of various anti-cancer treatments.
• Autophagy modulators are under investigation in clinical trials for combination therapies.

Conclusions:

• Manipulating autophagy presents a promising strategy to overcome tumor resistance and improve cancer therapy outcomes.
• Targeting autophagy holds potential for enhancing the effectiveness of diverse anti-cancer treatments.
• Further development of potent and selective autophagy inhibitors is crucial for clinical application.
