Autophagy Function and Dysfunction: Potential Drugs as Anti-Cancer Therapy

Area of Science:

• Cell Biology
• Molecular Biology
• Biochemistry

Background:

• Autophagy is a fundamental cellular process involving the degradation of damaged organelles and proteins.
• It plays a crucial role in cellular quality control and energy homeostasis, acting as a pro-survival mechanism.
• Dysregulation of autophagy is implicated in various pathologies, including neurodegeneration, metabolic disorders, and cancer.

Purpose of the Study:

• To provide a comprehensive overview of the regulatory mechanisms governing autophagy.
• To specifically examine the role of autophagy in cancer development and progression.
• To review currently approved autophagy-targeting drugs for treating malignancies.

Main Methods:

• Literature review of autophagy regulation.
• Analysis of autophagy's role in oncogenesis.
• Survey of approved autophagy-targeting therapeutics.

Main Results:

• Autophagy's complex regulatory network influences cellular fate.
• Aberrant autophagy is a hallmark of many cancers, impacting tumor growth and response to therapy.
• Several drugs targeting autophagy are approved for treating solid and non-solid tumors.

Conclusions:

• Understanding autophagy regulation is key to developing novel cancer therapies.
• Targeting autophagy presents a promising strategy for cancer treatment.
• Further research into autophagy modulators may yield new therapeutic avenues for various diseases.
