CUT&Tag analysis genome-wide maps of chromatin state in hCD34+ cells with X-RARG fusion genes overexpression.

CUT&Tag technology were used for high-throughput profiling of RARG fusion genes or PML-RARA with core promoters of its target genes in hCD34+ cells with RARG fusion genes or PML-RARA overexpression. We first expressed HA-tagged X-RARG fusions or HA-tagged PML-RARA in hCD34+ cells and then performed CUT&Tag with antibody to RARG fusion genes or PML-RARA and analyzed the binding of RARG fusion genes or PML-RARA with core promoters of its target genes. Common peaks for the binding sites of RARG fusions and PML-RARA and unique peaks for specific targets of RARG fusions that are not targets of PML-RARA were identified. Overall design: hCD34+ cells with HA-tagged X-RARG fusions or HA-tagged PML-RARA overexpression were harvested, and then the CUT&Tag assay was performed according to the manufacturer's protocol using Hyperactive Universal CUT&Tag Assay Kit for Illumina.
