摘要: Prostate cancer is the most commonly diagnosed tumor in men United States. Patients with hormone-refractory prostate are often treated paclitaxel, but of them eventually develop drug resistance. S-phase kinase associated protein 2 (Skp2) a component SCF (Skp1-Cullin1-F-box) type E3 ubiquitin ligase complexes. In present study, we investigated role Skp2 paclitaxel-resistant DU145-TxR or PC-3-TxR cells by silencing using inhibitors. We first confirmed that expression up-regulated compared their parental DU145 PC-3, respectively. Knockdown inhibitor treatment restored paclitaxel sensitivity. E-cadherin was decreased while Vimentin increased cells. addition, p27 inversely correlated Moreover, found to increase both and These results suggest cell resistance paclitaxel. may be potential therapeutic target for drug-resistant cancer.
