Elevating PLK1 Overcomes BETi-Resistance in Prostate Cancer via Triggering BRD4 Phosphorylation-dependent Degradation in Mitosis [ChIP-seq]

To investigate the effect of phosphorylated BRD4 at S24 and S1100 on transcription, we established C4-2 stable expressing BRD4 WT, S24/1100A, S24/1100D cell lines in which endogenous BRD4 has been knocked down by shRNA targeted to 3'-UTR. We then performed a CUT&RUN assay using anti-BRD4 or anti-H3K27Ac antibodies followed with a sequencing of ChIPed DNA from 4 different cells at 18 hour treatment of nocodazole. Overall design: Examination of BRD4 and H3K27Ac modification in human prostate cancer cells C4-2 cells expressing BRD4-WT, -S2A and -S2D mutants. There are 14 ChIP-Seq samples.
