SRP311480 PRJNA716073 GSE169277 Inhibition of a pathologic RBM39/MLL1 epigenomic regulatory complex with a dominant-negative peptides disrupts cancer cell transcription, proliferation and survival We report high-throughput profiling of RBM39 and MLL1 chromatin occupancy; H3K4me3 marks in T47D Control, T47D RBM39 KD and PME cells. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of RBM39, MLL1 and H3K4me3 in T47D and PME cells. We found that more than 4500 regions were cofound by RBM39 and MLL1. Overall design: Examination of RBM39 and MLL1 chromatin occupancy in T47D cells. GSE169277 parent_bioproject PRJNA603517
