Outline of Final Research Achievements |
We demonstrated the antitumor effect in vitro and in vivo of miR-205 that was also chemically modified by benzene-pyridine and had altered passenger sequence. In in vitro experiments, transfection with the synthetic miR-205 (miR-205BP) significantly inhibited the growth of human melanoma cells. On the basis of the results of a luciferase activity assay, miR-205BP directly targeted E2F1, as did Pre-miR-205. However, miR-205BP was much more resistant to RNase than Pre-miR-205 in fetal bovine serum and to RNase in mice xenografted with human melanoma tissues. In addition, the intratumoral injection of miR-205BP exhibited a significant anti- tumor effect compared with the case of control miRNA or Pre-miR-205 in human melanoma cell-xenografted mice.
