| Research Abstract |
By chemically modifying fullerene (C60) with polyethylene glycol (PEG), we succeeded in synthesizing water-soluble PEG-conjugated fullerene. MTS assays showed that thecombination of HIFU with PEG-conjugated fullerene resulted in synergistic growth inhibitory effects in PC-3 cells in vitro. In vivo, however, we failed to confirm reproducibility on the results of selective tumor tissue accumulation of fullerene because of instability of labeled PEG-conjugated fullerene. Using chicken tissue model we found synergistic tissue degenerating effects by this combination therapy, which showed no additive or synergistic antitumor effects in PC-3 xenograft models.
