ABSTRACT
<p><b>OBJECTIVE</b>To observe the suppression of the expression of androgen receptor (AR) gene in PC3 cells after AR-specific siRNAs transfection, and to search for the siRNA (s) with the greatest suppressing efficiency.</p><p><b>METHODS</b>Five AR-specific siRNAs were selected, RNAi expression vectors were constructed and transfected into PC3 cells, and the AR expression was detected by real time FQ-PCR and Western blot. A nonsense small RNA was set as negative control.</p><p><b>RESULTS</b>Compared with the control group, the AR expression decreased in various degrees in the 5 experimental groups (P < 0.05), and siRNA1, siRNA4 and siRNA5 showed the greatest suppressing efficiency as compared with the other experimental groups, with statistically significant difference (P < 0.05).</p><p><b>CONCLUSION</b>The AR-specific siRNAs could suppress the endogenous expression of target gene. Three siRNAs with great suppressing efficiency were identified and the expression vectors were constructed successfully. It can be applied in the future researches in vivo.</p>
