摘要
BACKGROUND. Improvements in the response rates to chemotherapy would represent an important advancement in the care of patients with metastatic prostate cancer. There is accumulating evidence that Survivin, a member of the inhibitor of apoptosis (IAP) family, is associated with both cancer progression and drug resistance. The purpose of this study is to investigate the role of Survivin in paclitaxel-resistance and whether the targeting of Survivin sensitizes prostate cancer cells to paclitaxel. METHODS. Human prostate cell lines PC-3, DU-145, and LNCaP were infected with replication-deficient adenoviruses encoding either wild-type Survivin [pAd-S(WT)], to examine Survivin overexpression effects, or a phosphorylation-defective Survivin Thr34 -> Ala dominant negative mutant [pAd-S(T34A)], to examine Survivin inactivation effects. The effects of wild-type or mutant Survivin on spontaneous and paclitaxel-induced apoptosis were investigated both in vitro and in vivo. RESULTS. Forced overexpression of wild-type Survivin with pAd-S(WT) increased resistance to paclitaxel in all cell lines, both in vitro and in vivo. Inhibition of Survivin using pAd-S(T34A) resulted in a significant increase in the rate of spontaneous and paclitaxel-induced apoptosis in all cell lines, both in vitro and in vivo. This effect was abolished by co-treatment with VAD-CHO (Calbiochem, San Diego, CA), a pan-caspase inhibitor, indicating that Survivin normally mediates resistance to paclitaxel through suppression of caspase-mediated apoptosis. CONCLUSIONS. Survivin mediates paclitaxel-resistance in prostate cancer cells. The inhibition of Survivin sensitizes prostate cancer cells to paclitaxel-induced apoptosis through a caspase-dependant mechanism in vitro and in vivo. (c) 2005 Wiley-Liss, Inc.
