Cetuximab scFv-Modified 5-FU Loaded Chitosan Nanoparticles: "A Novel Therapeutic Platform."
Background: Colorectal cancer [CRC] is among the most fatal types of cancer. An active targeting delivery system that specifically interacts with CRC cells could improve the therapy's outcomes. Herein, Cetuximab single-chain fragment variable antibody [scFv] fragments were conjugated to the surface of 5-FU encapsulated chitosan nanoparticles [CS NPs] to develop an effective therapeutic platform [scFv-CS/5-FU NPs].
Method: CS/5-FU NPs were synthesized using a special fluidic system. Encapsulation efficiency [EE], loading capacity [LC], and the drug release profile of the particles were determined. scFv fragments were produced recombinantly and tailored on the surface of CS/5-FU NPs. The physicochemical features of scFv-CS/5-FU NPs were also characterized. MTT and flow cytometry assay investigated the toxicity effect of scFv-CS/5-FU NPs on the HCT116 cell line.
Results: CS/5-FU NPs had a homogenous spherical shape. They possessed sustainable drugrelease behavior. The produced scFv-CS/5-FU NPs were also spherical. scFv-CS/5-FU NPs significantly decreased the viability of cancerous cells in a dose-dependent manner and induced apoptosis in 97.97% of targeted cells.
Conclusion: scFv-CS/5-FU NPs showed remarkable anti-CRC activity. This novel targeting delivery system reduced the effective dose of 5-FU which is of vital importance to decrease the devastating side effects of chemotherapy.
