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

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 gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at 18 hour treatment of nocodazole. Overall design: Comparative gene expression profiling analysis of RNA-seq data for C4-2_BRD4 WT, 2A, 2D upon nocodazole treatment.
