ABSTRACT
OBJECTIVE@#To construct FA targeted magnetic nanocomplex (FA-MNP-MMP-9-ASODN) loading matrix metalloproteinase 9 (MMP-9) antisense oligonucleotide (ASODN) and evaluate its targeting capacity and efficiency of gene transfection to folate receptor (FR) positive NPC.@*METHOD@#FA-MNP-MMP-9-ASODN was constructed by MMP-9-ASODN coupling with FA-MNP prepared by our research team through the aldehyde-ammonia condensation reaction. To analyze the feasibility of ASODN coupling with nanocarrier agarose gel electrophoresis. Two kinds of HNE-1 and CNE-2 cells and implanted tumors phagocytosis of FA-MNP-MMP-9-ASODN were observed by MRI on tumor-bearing nude mice, iron staining and TEM. To analyze gene transfection of the vector by observing FITC in the cell.@*RESULT@#The electrophoresis results revealed ASODN successfully coupling with FA-MNP. HNE-1 cell can effectively ingest the nanocomposite,with more FITC in the cell, but CNE-2 cell had not uptake for the nanocomposite, with no FITC in the cell. By comparing with CNE-2 tumor, HNE-1 tumor also can efficiently swallow the nanocomposite.@*CONCLUSION@#FA-MNP-MMP-9-ASODN nanocomplex is constructed successfully with good FA targeting ability and gene transfection.
