Outline of Final Research Achievements

We investigated whether the receptor activator of NF-kB ligand (RANKL)-binding peptide, an osteogenic peptide, can compensate for the decrease in bone formation caused by the absence of viral gene transfer of bone morphogenetic protein (BMP)-2, an osteogenic protein. After two weeks of the gene transfer by electroporation, both bone mineral density and bone microstructure indices were increased, and bone resorption indices were suppressed in the group treated with bone-forming peptides compared with the control group, suggesting that the osteogenic peptides may compensate for the reduction of the nonviral vector-induced bone formation.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果は、ウイルスベクターに比べて安全性の高い非ウイルスベクターを用いた遺伝子導入時の欠点を、骨形成促進ペプチドであるreceptor activator of Nf-kB ligand (RANKL)結合ペプチドの併用により改善できることを示唆している。
得られた結果は、ウイルスを用いた遺伝子治療より、より安全性が高い非ウイルスベクターを用いたBMP-2遺伝子導入法による新規骨形成法の開発に向けて有用な情報を与えている。本研究成果は、骨領域におけるウイルスを用いない遺伝子治療への可能性を広げた研究であり、局所へのペプチド投与方法をさらに検討することにより、今後の発展が期待される。
