Summary
A novel nanomotor drug delivery system effectively targets peritoneal metastasis (PM) in gastrointestinal cancers. This biomimetic system enhances drug delivery, activates immune responses, and significantly inhibits tumor growth, offering a promising new therapeutic approach.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Oncology
Background:
- Peritoneal metastasis (PM) is a late-stage cancer with poor prognosis.
- Current treatments like surgery and chemotherapy have limitations and risks.
Purpose of the Study:
- To develop and evaluate a novel nanomotor-based drug delivery system for enhanced peritoneal metastasis treatment.
- To investigate the system's targeting precision, tumor penetration, and therapeutic efficacy.
Main Methods:
- Fabrication of a biomimetic nanomotor (M@MnO2-Au-mSiO2@CDDP) using M1 macrophage membranes.
- Utilizing oxygen-driven nanomotors for targeted intraperitoneal drug delivery.
- In vitro and in vivo studies including gastric cancer organoid models.
Main Results:
- The nanomotor system demonstrated high precision targeting and deep tumor penetration.
- Significant inhibition of tumor growth, induction of apoptosis, and activation of immune responses were observed.
- Synergistic effects of targeted delivery, catalytic therapy, and immunotherapy were confirmed.
Conclusions:
- The nanomotor system shows great potential for treating peritoneal metastasis with enhanced efficacy and biocompatibility.
- This nanotechnology-based approach offers a promising alternative to traditional cancer therapies.
- Further clinical applications for targeted cancer therapies are anticipated.
