Project description:Gene expression in mouse pre-B cells transduced with Ikaros.
| PRJNA167286 | ENA
Project description:Ikaros family DNA binding proteins are critical regulators of B cell development. To identify Ikaros-regulated genes in primary pre-B cells we performed gene expression microarrays. We used retroviral gene transfer to express Ikaros proteins. Total RNA from 3 biological replicates of primary pre-B cells transduced with wild type Ikaros (HA-Ikaros-IRES-GFP) and control vector (IRES-GFP) was isolated 48h after infection.

Project description:Ikaros family DNA binding proteins are critical regulators of B cell development. To identify Ikaros-regulated genes in pre-B cells we performed gene expression studies at enhanced temporal resolution. We used retroviral gene transfer to express Ikaros proteins in the pre-B cell line B3. Total RNA from 2 biological replicates of B3 cells transduced with wild type Ikaros (HA-Ikaros-IRES-GFP) and DNA binding-deficient Ikaros mutant 159A (HA-159A Ikaros-IRES-GFP) was isolated 48h after infection. To increase the temporal resolution of Ikaros-regulated gene expression we transduced B3 cells with inducible Ikaros (HA-Ikaros-ERt2-IRES-GFP) and isolated total RNA from 3 biological replicates after 2 h and 6 h of exposure to 4-hydroxytamoxifen. Vector transduced B3 cells (ERt2-IRES-GFP) treated with 4-hydroxytamoxifen were used as controls.

Project description:The aim of the experiment was to compare to single and combined effect of Ikaros activation and IL-7 withdrawal in the Ikaros-null pre-B cell line BH1 The mouse BH1 pre-B cell line was transduced with retroviruses encoding Bcl2 and an Ikaros-estrogen receptor fusion protein. Doubly transduced cells were purified by FACS (BH1-Bcl2-Ik1ER). The transcriptome of these cells was analyzed at time 0, and after 6h and 24h of induction of Ikaros activity with 4-hydroxytamoxifen (4OHT) and/or withdrawal of IL-7. Samples from 2 independent experiments were analyzed (exp1 and exp2).

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

Project description:Ikaros DNA binding proteins are important regulators of haematopoiesis and genetic deletion of Ikaros results in severe developmental disturbances, including delayed thymocyte differentiation and an early and complete block in B cell development. Although Ikaros ChIP-seq data are available for mouse thymocytes and human haematopoietic progenitors, it has not been achieved in B cell progenitors. The goal of this study was to identify Ikaros binding sites in pre-B cells to define Ikaros target genes which could explain the essential role of Ikaros proteins in B cell differentiation. We carried out chromatin immunoprecipitation and high throughput sequencing (ChIP-seq) with antibodies to the C-terminus of endogenous Ikaros in B3 cells and with anti-haemagglutinin (HA) in B3 cells transduced with epitope-tagged HA-Ikaros.
