ERG factor mediates CXCR4 expression in VCaP cells. (A) ERG, CXCR4, and GAPDH gene expressions were determined in scrambled (Scr) and ERG siRNA-transfected VCaP cells, and ERG and CXCR4 gene expressions shown after normalization for GAPDH. (B) Scrambled and ERG siRNA-transfected VCaP cell lysates were immunoblotted with anti-ERG, anti-CXCR4 and anti-GAPDH antibodies. (C) Scr and ERG siRNA-transfected VCaP cells were treated with vehicle and R1881. Quantitative PCR analysis of CXCR4 and GAPDH was performed. (D) PSA gene expression was analyzed in scrambled and ERG siRNA-transfected VCaP cells.
