Real-time PCR, immunocytochemistryand western blotting were used to detect the expression of AR and IGF-1 in the presence or absence of variouskinase inhibitors. Low concentrations of DHT, estrone and flutamide increased the expression of AR and IGF-1,especially estrone, with concentration and time dependence. With DHT and flutamide, there was a significantalteration in AR expression (p<0.001). The results indicated expression of AR and IGF-1 genes to be influencedby DHT, estrone and flutamide in LNCaP cells, regulated by multiple signal pathways.
