Increase of Skp-2, which is involved in the degradation of cell cycle regulators including p27Kip1, p21 and c-myc, is one of the important mechanisms for dysregulation of cell cycles in various cancers. We applied RNA interference (RNAi) for Skp-2 by using HIV-lentiviral or adenoviral vectors for a human small-cell lung carcinoma cell line with increased Skp-2 to evaluate RNAi strategy for cancer gene therapy. HIV-lentivirus-mediated RNAi for Skp-2 resulted in efficient inhibition of the in vitro cell growth of cancer cells with increased Skp-2 through the increase of p27Kip1 and p21, but no significant effect on the growth of cells without high Skp-2 expression. Furthermore, intratumoral administration of adenovirus siRNA vector for Skp-2 efficiently inhibited growth of established subcutaneous tumor on NOD/SCID mice. These results indicate that the Skp-2 RNAi may be a useful strategy for gene therapy of cancers with high Skp-2 expression.
