Autophagy: Shedding Light on the Mechanisms and Multifaceted Roles in Cancers

Area of Science:

• Cellular Biology
• Molecular Biology
• Biochemistry

Background:

• Autophagy is a fundamental catabolic process in eukaryotes for degrading and recycling cellular components.
• It involves selective or non-selective removal of damaged organelles, protein aggregates, and macromolecules.
• Dysregulation of autophagy-related genes impacts cellular homeostasis and is linked to human diseases, including cancer, neurodegeneration, and inflammation.

Purpose of the Study:

• To systematically review the molecular mechanisms of autophagy.
• To present current research on autophagy's dual role in cancer development (pro- and anti-tumorigenic effects).
• To summarize advancements in autophagy-targeting cancer therapies.

Main Methods:

• Literature review of molecular mechanisms of autophagy.
• Analysis of studies investigating autophagy's role in cancer progression.
• Summary of current therapeutic strategies targeting autophagy in tumors.

Main Results:

• Autophagy's complex role in cancer, acting as both a tumor suppressor and promoter.
• Identification of key molecular pathways and genes involved in autophagy.
• Overview of emerging therapeutic approaches that modulate autophagy for cancer treatment.

Conclusions:

• Autophagy is a critical cellular process with significant implications for human health and disease.
• Understanding autophagy's dual role in cancer is essential for developing effective therapeutic strategies.
• Targeting autophagy presents a promising avenue for novel cancer treatments.
