Identifying  RARG fusions or PML-RARA binding genes or analysis the epigenetic changes (H3K27ac, H3K4me1, and H3K4me3)  in hCD34+ cells overexpressing CPSF6::RARG and NUP98::RARG.
To understand how RARG fusion proteins regulate their target genes in the hematopoietic system, we overexpressed fusions or PML-RARA in hCD34+ cells and identified target genes that are regulated by RARG fusions. We found that RARG fusions selectively upregulated BCL2 and ATF3 in HSPCs, driving uncontrolled proliferation and disrupting the differentiation of RARG-AML cells.To investigate the mechanism how RARG fusions mediate activation of their downstream targets such as BCL2 and ATF3, we dected the epigenetic changes (H3K27ac, H3K4me1, and H3K4me3) associated with RARG fusions binding in hCD34+ cells overexpressing CPSF6::RARG and NUP98::RARG. Overall design: 2000,000 hCD34+ cells with  CPSF6-RARG,NUP98-RARG,  HNRNPC-RARG, NPM1-RARG, PML-RARG or PML-RARA overexpression or hCD34+ cells with or without CPSF6::RARG or NUP98::RARG overexpression were harvested and performed ChIP-seq assay.
