GenomicsHistone Demethylase Lsd1 is Required to Repress Hematopoietic Stem and Progenitor Cell Signatures During Blood Cell Maturation
Here we describe that lysine-specific demethylase 1 (Lsd1/KDM1a), which demethylates histone H3 on LysM-bM-^@M-^I4 or LysM-bM-^@M-^I9 (H3K4/K9), is an indispensible epigenetic governor of hematopoietic differentiation. Integrative genomic analysis in primary hematopoietic cells, combining global occ...

TranscriptomicsExpression data from BCL11A-null and wild-type bone marrow erythroid pregenitors
BCL11A is a critical mediator of hemoglobin switching and gamma-globin silencing. In this study, we showed the BCL11A is required in vivo for developmental silencing of gamma-globin genes in adult animals. We used microarray to determine the changes in gene expression profile after loss of BCL11A in...

TranscriptomicsGene expression data of Lsd1fl/fl and Lsd1fl/fl Mx1Cre CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs
We discovered that mice that lack Lsd1 in hematopoietic cells were exhibited increased frequencies of CD150+ CD48- lin- c-Kit+ Sca-1+ LT-HSCs, but completely lacked the lin- c-Kit+ Sca-1- myeloid progenitor compartment. To determine the genes altered by Lsd1-loss, CD150+ CD48- lin- c-Kit+ Sca-1+ LT-...

TranscriptomicsExpression data for conditional Dnmt1knockout hematopoietic stem and progenitor cells
DNA methylation is essential for mammalian development and plays crucial roles in a variety of biological processes. The DNA methyltransferase Dnmt1 serves to maintain parental cell methylation patterns on daughter DNA strands in mitotic cells, however, the precise role of Dnmt1 in regulation of qui...

GenomicsComparative profiling of chromatin state maps and transcription factor occupancy during human fetal and adult erythropoiesis
We report the comparative investigation of genome-wide chromatin state maps, transcription factor (TF) occupancy, and gene expression profiles from developing red cell precursors at two developmental stages. Contrasting the similarities and differences between fetal and adult erythropoiesis provides...

GenomicsScl specifies hemogenic endothelium and inhibits cardiogenesis via primed enhancers [ChIP-seq]
Scl/Tal1 confers hemogenic competence and prevents cardiomyogenesis in embryonic endothelium. Here we show that Scl both directly activates a broad gene regulatory network required for hematopoietic stem/progenitor cell (HS/PC) development, and represses transcriptional regulators required for cardi...
