Autophagy-Targeting Nanomedicine: Strike at the Heart of the Cancer via Precise Modulation of Autophagy

Area of Science:

• Biomedical Engineering
• Cancer Therapy
• Nanomedicine

Background:

• Autophagy is a cellular process crucial for metabolic homeostasis and organelle renewal.
• Autophagy plays a significant role in tumor progression and has become a key target in cancer therapies.
• Integrating autophagy regulation into mainstream cancer treatments is a major emerging trend.

Purpose of the Study:

• To review the application of autophagy-targeting nanomedicine (ApT-NM) in tumor therapy.
• To discuss how ApT-NM can modulate autophagy to either inhibit protective mechanisms or induce cancer cell death.
• To summarize advanced nanoplatforms combining ApT-NM with other therapeutic modalities.

Main Methods:

• Review of current literature on autophagy-targeting nanomedicine for cancer.
• Analysis of unmodified and functionalized nanoparticles carrying autophagy modulators.
• Examination of combined therapeutic strategies involving nanomedicine, chemotherapy, radiotherapy, and other therapies.

Main Results:

• ApT-NM can be designed to inhibit protective autophagy, thereby reversing treatment resistance in tumors.
• ApT-NM can also induce autophagy to promote cancer cell death via type II apoptosis.
• Advanced nanoplatforms integrate ApT-NM with chemotherapy, radiotherapy, photothermal, and photodynamic therapies for enhanced efficacy.

Conclusions:

• Autophagy-targeting nanomedicine presents a versatile strategy for cancer treatment.
• ApT-NM holds potential for overcoming drug resistance and enhancing cancer cell apoptosis.
• Further research into ApT-NM is crucial for advancing cancer therapy development.
