Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive acute leukemia, which appears to be originated from the precursor of plasmacytoid dendritic cells (pDCs). Chromosomal translocation t(6;8)(p21;q24) is often seen in BPDCN patients. RUNX2, located on chromosome 6p21, has been shown to regulate the differentiation of pDCs. We found that expression of RUNX2 and C-MYC, an potent oncogene, were significantly up-regulated in BPDCN bone marrow cells in patients as well as a cell line, CAL1, harboring t(6;8)(p21;q24). To detect accuarate translocation sites, we examined whole genome sequencing in CAL1 cells. To find super-enhancer of BPDCN, we examined ChIP-seq analysis with H3K27Ac antibodies in CAL1 cells. Given that RUNX2 appeared to be critical for the development of BPDCN, we examined gene expression profiles of shRNA-directed RUNX2 transduced CAL1 cells compared to the control vector transduced CAL1 cells.
