A Multifunctional Delivery System for Remodulating Cell Behaviors of Circulating Malignant Cells to Prevent Cell...

Area of Science:

• Oncology
• Molecular Biology
• Biotechnology

Background:

• Cell fusion is crucial for cancer progression and metastasis.
• Current methods struggle to modulate and evaluate cell fusion for personalized therapy.

Purpose of the Study:

• To develop a multifunctional delivery vector for targeted gene editing and cell fusion detection in cancer.
• To inhibit cancer cell fusion and metastasis through epidermal growth factor receptor (EGFR) knockout.

Main Methods:

• Utilized a multifunctional delivery vector targeting circulating malignant cells (CMCs).
• Delivered a genome editing plasmid for EGFR knockout and a molecular beacon-based AND logic gate for fusion detection.
• Assessed cell fusion capability of edited versus unedited CMCs with human umbilical vein endothelial cells (HUVECs).

Main Results:

• The vector specifically targeted CMCs and delivered the gene editing payload.
• EGFR knockout significantly inhibited the cell fusion capability of CMCs.
• The AND logic gate reliably detected cell fusion events.

Conclusions:

• This strategy effectively modulates cancer cell fusion behavior and provides a tool for precise evaluation.
• Offers a novel therapeutic approach to prevent cancer progression and metastasis.
• Enables personalized therapy by evaluating cancer cell fusion accurately.
