Influence of TRAIL receptors and K V 10.1. A) DU145 cells were pre-incubated with anti-TRAIL-R1 antibody, anti-TRAIL-R2 antibody or a mixture of both for 2 h. Cells were then treated with scFv62-TRAIL in the presence of CHX (n = 2). B) DU145 cells were transfected with siRNA against TRAIL-R1 and/or TRAIL-R2 for 24 h and then treated with 50 U/ml scFv62-TRAIL in presence of 5 μg/ml CHX; apoptosis was measured by flow cytometry (n = 3). C) Quantitative real-time PCR analysis: DU145 cells were transfected with siRNA against TRAIL-R1 and/or TRAIL-R2 and analyzed for mRNA expression of death receptors. Quantitative real-time PCR analysis of D) TRAIL-R1, E) TRAIL-R2 and F) KV10.1 expression after chemotherapeutic treatment: doxorubicin (1.8 μM), etoposide (50 μM), roscovitine (10 μM), 5-fluorouracil (100 μM).
