Abstract
To investigate the ability of extracellular vesicles (EVs) to deliver oxaliplatin to epidermal growth factor receptor (EGFR+) colorectal cancer cells and increase oxaliplatin’s cytotoxicity. Oxaliplatin was passively loaded into a stable cell line expressing cetuximab in membranes. EVs were collected and characterized for size, and their ability to target EGFR+ cells was tested. Cytotoxicity experiments were performed, and a xenograft cancer animal model was used to confirm the specific accumulation of oxaliplatin-loaded EVs with cetuximab-expressing membranes in EGFR+ cells. EVs with cetuximab-expressing membranes were successfully produced and used to encapsulate oxaliplatin, resulting in consistently sized oxaliplatin-loaded EVs with cetuximab-expressing membranes. The oxaliplatin-loaded EVs with cetuximab-expressing membranes were specifically accumulated by EGFR+ cells, leading to significant cytotoxic effects on these cells. In the animal model, the oxaliplatin-loaded EVs with cetuximab-expressing membranes accumulated specifically in EGFR+ cells and significantly enhanced oxaliplatin’s therapeutic efficacy against EGFR+ cancer cells. EVs with membrane-expressed bioactive molecules are a promising strategy for delivering therapeutic agents to EGFR+ colorectal cancer cells.

期刊介绍:
Aim:
Recognizing cancer as a group of diseases caused by nanostructural problems (i.e. with DNA) and also that there are unique benefits to approaches inherently involving nanoscale structures and processes to treat the disease, the journal Cancer Nanotechnology aims to disseminate cutting edge research; to promote emerging trends in the use of nanostructures and the induction of nanoscale processes for the prevention, diagnosis, treatment of cancer; and to cover related ancillary areas.
Scope:
Articles describing original research in the use of nanostructures and the induction of nanoscale processes for the prevention, diagnosis and treatment of cancer (open submission process). Review, editorial and tutorial articles picking up on subthemes of emerging importance where nanostructures and the induction of nanoscale processes are used for the prevention, diagnosis and treatment of cancer.
