Mechanisms of Ikaros Tumor Suppression with HDAC1 through distinct histone markers in Pre-B ALL Leukemia


ABSTRACT: Ikaros functions as a master regulator of lymphocyte differentiation and a tumor suppressor. Ikaros binds DNA and regulates gene expression by chromatin remodeling. Mechanisms of Ikaros-mediated tumor suppression are unknown. Here we examined genome-wide occupancy of Ikaros and histone deacetylase 1 (HDAC1) and Histone midificaition markers in human leukemia, and found that the Ikaros and HDAC1 showed similar binding partern and HDAC1–DNA interactions are associated with the presence of bivalent chromatin, and the recruitment of HDAC1 by Ikaros is associated with bivalent chromatin at Ikaros target genes.
