ABSTRACT
<p><b>OBJECTIVE</b>The aim of the present study is to compare the effects of two alpha1-adrenoceptor antagonist terazosin and alfuzosin together with one alpha-adrenoceptor antagonist phenoxybenzamine on androgen-independent prostate cancer cell lines PC-3 and DU145.</p><p><b>METHODS</b>Two androgen- independent cell lines, PC-3 and DU145, were used to determine the cell viability, colony-forming ability as well as cell cycle characteristics after exposure to these three drugs.</p><p><b>RESULTS</b>This study showed that terazosin inhibited not only prostate cancer cell growth but also colony-forming ability, which is the main target of clinical treatment. On the other hand, alfuzosin and phenoxybenzamine have no effect on cell viability and colony forming ability of PC-3 and DU145. In addition, the terazosin inhibits cell growth through G(1) phase cell cycle arrest.</p><p><b>CONCLUSION</b>This study provided the evidence that alpha1-adrenoceptor antagonist terazosin may have a therapeutic potential in the treatment of advanced androgen-independent prostate cancer.</p>
