Research Abstract

Trials of gene therapies have been carried out for malignant tumors and congenital gene disorders,; however, there are problems such as the low efficiency and risk for applying human being, and ideal methods of gene therapy are not yet developed.. We designed nanocoloid that enclosed expression plasmid inside and, ligand peptide outside of small particle for development of a specific gene delivery system. When We searched expression of EGFR in oral squamous cell carcinoma cell lines (9.22, HSC2, HSC3, HSC4, Ca SAS) by Western blot, and all cell lines expressed EGFR We examined the binding affinity of EGFR and synthesized EGF peptide by BireCore X. As a result, it became clear that synthesized peptide bound to EGFR. Next, we examined the induction effect of nanocoloid to oral carcinoma cell lines. The efficiency of transfection was approximately 30%, and we aimed to improve the efficiency. We next examined the effects of adrenomedullin antagonist that has the ability to inhibit angiogenesis. The vector that has the sequence for inhibitory effects on aderenomedullin reduced the Growth of tumor xenografts in nude mice.
These results imply that specific gene delivery for tumor environment could be the therapeutic agents for solid cancers.
