H3K9ac and H3K27ac Cut&Tag profiling of wild type and Rbm25-deficient Bone Marrow Derived macrophage
Purpose: To transcriptome widely reveal histone acetylation modification H3K9ac and H3K27ac regulation by Rbm25, we performed Cleavage Under Targets and Tagmentation (CUT&Tag) analysis of wild-type (WT) and Rbm25-deficiency BMDMs. Methods: Mouse BMDMs were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse M-CSF (20ng/ml). BMDMs were stained to confirm the surface expression of CD11b and F4/80. Cells with purity >97.5% were used for subsequent experiments. WT and Rbm25 deficient BMDMs were stimulated with LPS (100ng/ml) for 4 hours. Results: We carried out CUT&Tag assays using antibody against H3K9ac or H3K27ac, and found the global influence of Rbm25 in regulating H3K9ac and H3K27ac of transcription regulatory regions of key genes for inflammatory macrophage effector function. Overall design: Cleavage Under Targets and Tagmentation (CUT&Tag) analysis for histone modifications H3K9ac and H3K27ac in WT and Rbm25-deficiency BMDMs stimulated with LPS.
