Project description:Exosc8 and Exosc9 are components of the exosome that establish a barricade to erythroid maturation. Here, we knocked down Exosc8 in fetal liver-derived erythroid progenitor cells to determine the cohort of Exosc8-regulated genes in erythroid cells. Freshly isolated fetal liver progenitor cells were infected with retrovirus expressing shRNA targeting either luciferase or Exosc8. Total RNA was isolated from these cells after 3 days ex-vivo culture, during which the cells underwent erythroid maturation.

Project description:Here, we have used digital genomic footprinting to precisely define protein localization for several adipogenic transcription factors at a genome-wide level. In combination with ChIP-seq data, these analyses reveal novel molecular insight into the organization of transcription factors at hotpot regions, which provides a new framework for understanding transcription factor cooperativity on chromatin. Digital genomic footprinting and gene expression in 3T3-L1 pre-adipocytes by high throughput sequencing.

Project description:Extensively Self Renewing Erythroblasts (ESREs) are cultured erythroid cells derived from yolk sack or fetal liver. Transcriptome analyses were conducted on ESREs using RNA-seq and compared to published transcriptome analyses of uncultured erythroid cells.

Project description:We over-expressed ESlncRNA (AK148461) in fetal liver erythroid progenitor cells (Lin-cells), followed by microarray analysis to examine the global changes of gene expression level. We showed that ESlncRNA has an anti-apoptotic activity during mouse erythropoiesis. Compare the gene expression level in vector transduced fetal liver erythroid progenitor cells (Lin-cells) with that in ESlncRNA transduced fetal liver erythroid progenitor cells (Lin-cells).

Project description:The erythroid Krüppel-like factor EKLF/KLF1 is a hematopoietic transcription factor binding to CACCC DNA motif and participating in the regulation of erythroid differentiation. With combined use of microarray-based gene expression profiling and promoter-based ChIP-chip assay of E14.5 fetal liver cells from wild type (WT) and EKLF-knockout (Eklf-/-) mouse embryos, we have identified the pathways and direct target genes activated or repressed by EKLF. This genome-wide study together with molecular/ cellular analysis of mouse erythroleukemic cells (MEL) indicate that among the downstream direct target genes of EKLF is Tal1/Scl. Tal1/Scl encodes another DNA-binding hematopoietic transcription factor TAL1/SCL known to be an Eklf activator and essential for definitive erythroid differentiation. Further identification of the authentic Tall gene promoter in combination with in vivo genomic footprinting approach and DNA reporter assay demonstrate that EKLF activates Tall gene through binding to a specific CACCC motif located in its promoter. These data establish the existence of a previously unknow positive regulatory feedback loop between two DNA-binding hematopoietic transcription factors that sustains the mammalian erythropoiesis.

Project description:Extensively Self Renewing Erythroblasts (ESREs) are cultured erythroid cells derived from yolk sack or fetal liver. Transcriptome analyses were conducted on ESREs using RNA-seq and compared to published transcriptome analyses of uncultured erythroid cells. RNA-seq was conducted on proliferating Extensively Self Renewing Erythroblasts (ESREs) and ESREs after one day of maturation. Biologic duplicates were done at each time point.
