Assay Method Information

Assay Name:  Transactivation Assay
Description:  PC-3 cells (Kaighn et al., Invest. Urol. 17: 16-23, 1979) were plated out at a density of 10000 cells per well of a 96-well cell culture plate in RMPI 1640 medium (F1235, Biochrom AG, Berlin, Germany), which contained activated charcoal-treated calf serum (FCS Serum Gold, PAA Laboratories) at a concentration of 5% (v/v). On the next day the cells were transiently transfected with the pSG5-vector (#216201 Stratagene), which contained the sequence of the androgen receptor mutant W741C (Haapala et al., Lab Invest. 81(12): 1647-51, 2001), and with a reporter plasmid based on pGL4.14 (#E6691, Promega) with the luciferase-gene (from Photinus pyralis) under the control of the MMTV promoter (Cato et al., EMBO J. 6: 363-8, 1987). The cells were treated with the test substances in concentrations from 1×10^−8 to 1×10^−10 M in the presence of 1×10^−10 M R1881 and were incubated overnight at 37° C. and 5% CO2. After 24 hours, 100 μl of Steady Glo Lysis and Detection reagent (E2550, Promega) was added per well and the luminescence was read in a Victor3 Luminometer (PerkinElmer) for 1 second per well. The luminescence values obtained were normalized, wherein 100% corresponded to the effect of the unstimulated control (without R1881), and 0% corresponded to the effect of the stimulated control (R1881 plus DMSO instead of test substance).
