FIGURE 4. COBRA1 does not affect the ligand sensitivity of AR-mediated transcriptional activation.
The control and COBRA1 knockdown cells were transfected with the MMTV-luciferase reporter plasmid, and subsequently treated with a serial 10-fold dilution of DHT, ranging from 10-11 M to 10-8 M. Transfected cells were also treated with AR antagonist flutamide (10-6 M) in the presence of 10-9 M DHT to ascertain the androgen-dependency of the observed luciferase expression.
