Abstract

It is difficult to introduce DNA in non-invasive manner into oral cancer cells as well as primary cells for gene manipulation and expression in vivo. So far, several methods for a gene delivery have been performed to solve this problem. Magnetofection is one of the recent methods for gene transfer, and nanoparticles are applied under a magnetic field for DNA delivery. We investigated whether the magnetofection increases the efficiency of a gene delivery into several oral cell lines. By using a plasmid coding the green fluorescent protein (GFP), the efficiency of gene transfer by magnetofection was compared with those by using the calcium phosphate and the commercial transfection agent. Indeed, the magnetofection increased the green fluorescent signal in cells, suggested that this method apparently enhance the efficiency of gene delivery without any defects in various oral cancer cell lines. Finally, we have shown that magnetofection can be a useful technique for gene delivery to difficult-to-transfect cells to perform a functional study of genes in vivo.
