The ChIP-PCR results demonstrated that AR occupancy was significantly higher for all 6 tested genes (t-test, P < 0.05) in E006AA cells compared to VCaP cells (Figures 3(a) and 3(b)), suggesting that the enriched AR binding of these 6 cancer-associated genes may be related to differential cancer aggressiveness in AA PCa versus CA PCa. The gene discussed is AR; the disease is posterior cortical atrophy.
