AR-V7 does not regulate PARG levels or activity. (a) LNCaPAR-V7/pHage cells were plated in medium with 10% CSS. Cells were treated with 50 ng/ml Dox for 0, 2, 5, and 7 days. Protein levels of PAR, PARG, PARP-1, AR, AR-V7, and Tubulin were tested by Western blotting. The experiment was repeated 3 times and a representative blot is shown. (b,c) LNCaPAR-V7/pHage cells were placed in medium with 10% CSS for 24 hours and treated with 50 ng/ml Dox or 10 nM R1881 overnight as indicated. Recruitment of AR-FL and AR-V7 to PSA promoter (b) and PARG (c) were measured by ChIP-qPCR using Igg as control. (*p ≤ 0.05; ***p ≤ 0.001). In panels b-c, each bar represents an average of 3 biological replicates, the experiment was repeated 3 times.
