Project description:IRF2, IRF6, and MYB are candidate regulators of human erythropoiesis. We here examine primary CD34+ hematopoietic stem/progenitor cells (HSPCs)-derived erythroid progenitors with control, IRF2, IRF6, or MYB shRNA lentiviral transduction prior to differentiation. Gene expression microarray profiling datasets for MYB shRNA and control shRNA were obtained from Gene Expression Omnibus (GEO) under accession number GSE25678. The data were analyzed together with the datasets obtained in this study. Primary maturing adult erythroblasts were generated ex vivo from CD34+ hematopoietic stem/progenitor cells (HSPCs) using a serum-free two-phase liquid culture system. CD34+ HSPCs were transduced with lentiviruses containing shRNAs against IRF2 or IRF6 gene, selected and differentiated to proerythroblasts (ProEs). Cells were harvested at day 5 of differentiated and total RNA were extracted. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.

Project description:Transcription factor paralogs may share a common role (e.g. Hox) in staged or overlapping expression in specific tissues. In other examples, members have distinct roles in a range of embryologic, differentiation or response pathways (e.g. Tbx, Pax). For the Interferon Regulatory Factor (IRF) family of transcription factors, mice deficient in Irf1, Irf2, Irf3, Irf4, Irf5, Irf7, Irf8 or Irf9, have defects in the immune response but display no embryologic abnormalities. Mice deficient for Irf6 have not been reported, but in humans, mutations in IRF6 cause two Mendelian orofacial clefting syndrome, and genetic variation in IRF6 confers risk for isolated cleft lip and palate. Mice deficient for Irf6 have abnormal skin, limb and craniofacial development. Histological and gene expression analyses indicate that the primary defect is in keratinocyte differentiation and proliferation. This study describes a novel role for an IRF family member in epidermal development. Experiment Overall Design: Skin from E17.5 mice was removed and flash frozen for RNA extraction and hybridization on Affymetrix microarrays.

Project description: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 important insights into the erythroid gene expression programs and gene regulatory networks. Specifically, comparative analyses of human erythropoiesis identify developmental stage-specific enhancers as primary determinants of stage-specific gene expression programs. We find that master regulators, such as GATA1 and TAL1, cooperatively act within active enhancers but have little predictive value for stage-specific enhancer activity. Instead, a set of stage-specific co-regulators collaborates with master regulators and contributes to differential gene expression. We further identify and validate IRF2, IRF6, and MYB as effectors of adult-stage expression program. Thus, the combinatorial assembly of master regulators and transcriptional co-regulators at developmental stage-specific enhancers controls gene expression programs and temporal regulation of transcriptional networks in a mammalian genome. Examination of various histone modifications and transcription factor occupancy by ChIP-seq in fetal and adult proerythroblasts.
