*2.6. Knockdown of AR-V7*

AR-V7 expression was transiently knocked down in LNCaP95-DR cells using LipofectamineTM RNAiMAX (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's instructions. AR-V7 siRNAs (Silencer® Select siRNAs) were obtained from Life TechnologiesTM (Grand Island, NY, USA). The sense sequence of siRNA for AR-V7 was 5-GUAGUUGUGAGUAUCAUGATT-3 .
