Figure 5. AR is a component of telomeres.
(A, B), AR-ChIP contains telomere DNA. LNCaP cell chromatin was subjected to immunoprecipitation with antibodies to AR, TRF2, Rap1, or normal IgG (negative control). (A), DNA was purified from the ChIP and analyzed for the presence of AR binding sequences in the PSA gene (ARE III in PSA promoter/enhancer) [
