Transcriptome analysis of normal erythroid progenitors and erythroleukemia cells

ABSTRACT: We compared the transcriptomes of ES cell derived erythroid progentor cells (ES-EP) and murine erythroleukemia (MEL) cells stably transfected with Gata-1 fused to ER. RNA was isolated from duplicate proliferating cultures of MEL and ES-EP using Affymetrix GeneChip Mouse Gene 1.0 ST.

PU.1 is a hematopoietic transcription factor that is required for the development of myeloid and B cells. PU.1 is also expressed in erythroid progenitors, where it blocks erythroid differentiation by binding to and inhibiting the main erythroid promoting factor, GATA-1. However, other mechanisms by which PU.1 affects the fate of erythroid progenitors have not been thoroughly explored. Here, we used ChIP-Seq analysis for PU.1 and gene expression profiling in erythroid cells to show that PU.1 regu ...[more]

Genome-wide binding pattern of PU.1 in normal erythroid progenitors and erythroleukemia cells

Project description:We find that the myeloid master regulatory transcription factor, PU.1, binds to >16,000 sites in both normal and leukemic erythroid cells. Of these bound sites, ~7,000 lie within 2kb of TSS of a gene, suggesting PU.1 may regulate a large number of genes in erythroid cells. Coupling this data with gene expression analysis, we show PU.1 directly regulates several critical signaling pathways in erythroid cells. Assaying PU.1 occupancy in normal and leukemic erythroid cells

Genome-wide occupancy map of GATA-1 in proliferating and differentiating murine ES cell derived erythroid progenitors (ES-EP)

Project description:We find GATA-1 occupies 6,600 sites in proliferating erythroid progenitors and 10,600 sites in differentiating progenitors. 80-90% of GATA-1 binds within intragenic or intergenic regions, while <20% of GATA-1 is found within 2kb of TSS. Assaying GATA-1 occupancy in normal erythroid progenitors in both proliferating and differentiating conditions.

Expression profile of human ESC, ESC-drived definitive endoderm and endodermal progenitor cells

Project description:Endodermal progenitor cells (EP cells) are derived from human embryonic stem cell(ESC)-derived definitive endoderm (DE) cells. EP cells are cultured in high BMP media and DE cells are in high Activin media. Both cells can be further differentiated to liver, pancreas, etc. We used microarray to detail the global gene expression profile of DE cells and EP cells to delineate the difference of DE cells and EP cells. ESCs were sorted by SSEA3 and SSEA4. DE cells and EP cells were sorted by CXCR4 and CD117. Sorted cells were lysed in RLT buffer. RNA was extracted and hybridized to Affimetrix microarrays. Each group had 3 biological replicates.

Bait-capture based single molecule footprinting of different mouse cell lines

Project description:Bait-capture based Single Molecule Footprinting (SMF) data from Kreibich et al., 2022. SMF data is obtained by treating extracted nuclei with a GpC methyltransferase, where binding of proteins on DNA, e.g. nucleosomes and transcription factors (TFs), leave behind unmethylated GpCs as footprints. Data in this experiment comprises SMF data obtained from WT embryonic stem cells (ES), DNMT TKO ES, TET TKO ES, F1 hybrid ES (129/CAST), neural progenitor (NP),�myoblast (C2C12) and�murine erythroleukemia (MEL)�cells. These data were generated by employing Agilent Sure-Select Mouse Methyl-Seq kit, enriching the sample for cis-regulatory regions of the mouse genome prior to library preparation. Thus, these data contain high coverage accessibility information at regulatory loci in different cell types. The SMF procedure maintains the endogenous DNA methtylation in CpG context, allowing the simultaneous detection of chromatin accessibility, TF binding and endogenous DNA methylation.

mRNA profiling of Pontin depleted ES cells and Oct4 depleted ES cells

Project description:In order to investigate the cooperative roles of Pontin and Oct4 for self-renewal and pluripotency in mouse ES cells, we performed mRNA-sequencing analysis from mRNAs isolated from Pontin- and Oct4-depleted ES cells. This analysis provides insight into molecular mechanisms for maintaining ES cell identity. mRNA expression profiles of Pontinf/f; CreER ES cells at 0, 3, or 4 days post-treatment with OHT (wild type and Pontin-depleted ES cells) and ZHBTc4 ES cells at 2 days post-treatment with tetracycline (Oct4-depleted ESE cells) were examined by Illumina Hiseq2000.
