Effect of EBP1 and lapatinib on AR expression. A16 and C13 cells (a) or C81V and C81 EBP1 cells (b) were grown in androgen-depleted media for 3 days. R1881(10−9 M) and lapatinib (1 μM) were added 24 h prior to harvesting cells. Western blotting was performed for AR and GAPDH as indicated. Representative of 3 experiments. The numbers below the blots indicate the relative densities of AR normalized to GAPDH. The value of each untreated cell line was set at 1
