Project description:Purpose: The purpose of this study is to identify the genome-wide binding sites for IRF4 interaction partners PU.1, BATF, and JunB in dendritic cells. These ChIP-seq data were integrated with gene expression analysis in IRF4-sufficient and -deficient BMDCs in order to assemble an IRF4 gene regulatory network. Hematopoietic bone marrow progenitors from C57BL/6 mice were differentiated with GM-CSF and IL-4 for 5 days. On day 6, BMDCs were stimulated for 6 hours with 100ng/ml LPS. Fixed chromatin was immunoprecipitated with anti-PU.1, BATF, and JunB antibodies and subjected to high-throughput sequencing. The sequencing data for the input DNA was previously submitted as GSM999807.

Project description:IRF4 is critical for differentiation of various CD4+ effector T cells, such as T helper 1 (Th1), Th2, and Th17 subsets, through interaction with BATF-containing AP-1 heterodimers. A major BATF heterodimeric partner, JunB, regulates Th17 differentiation, but the role of JunB in other CD4+ effector T subsets is not fully understood. Here we demonstrate that JunB is essential for accumulation of Th1 and Th2 cells, as well as Th17 cells, both in vitro and in vivo. In mice immunized with lipopolysaccharide (LPS), papain, or complete Freund’s adjuvant (CFA), that induce predominantly Th1, Th2 and Th17 cells, respectively, accumulation of antigen-primed, Junb-deficient CD4+ T cells is significantly impaired. Loss of JunB decreases viability of cells activated under Th1-, Th2-, and Th17-polarizing conditions. RNA-sequencing (RNA-seq) and chromatin immunoprecipitation sequencing (ChIP-seq) reveal that JunB directly regulates expression of various genes that are commonly induced in priming of naïve CD4+ T cells, including a pro-apoptotic gene Bcl2l11 (encoding Bim), and genes that are specifically induced in Th1, Th2, and Th17 cells. Furthermore, JunB colocalizes with BATF and IRF4 at genomic regions for approximately half of JunB direct target genes. Taken together, JunB, in collaboration with BATF and IRF4, serves a critical function in differentiation of diverse CD4+ T cells by controlling common and lineage-specific gene expression.

Project description:The importance of unanchored Ub in innate immunity has been shown only for a limited number of unanchored Ub-interactors. We investigated what additional cellular factors interact with unanchored Ub and whether unanchored Ub plays a broader role in innate immunity. To identify unanchored Ub-interacting factors from murine lungs, we used His-tagged recombinant poly-Ub chains as bait. These chains were mixed with lung tissue lysates and protein complexes were isolated with Ni-NTA beads. Sample elutions were subjected to mass spectrometry (LC-MSMS) analysis.

Project description:Knockdown of the transcription factor PU.1 (Spi1) leads to acute myeloid leukemia (AML) in mice. We examined the transcriptome of PU.1 knockdown hematopoietic stem cells (HSC) in the preleukemic phase by linear amplification and genome-wide array analysis to identify transcriptional changes preceding malignant transformation. Hierarchical cluster analysis and principal component analysis clearly distinguished PU.1 knockdown from wildtype HSC. Jun family transcription factors c-Jun and JunB were among the top downregulated targets. Retroviral restoration of c-Jun expression in bone marrow cells of preleukemic mice partially rescued the PU.1-initiated myelomonocytic differentiation block. Lentiviral restoration of JunB at the leukemic stage led to reduced clonogenic growth, loss of leukemic self-renewal capacity, and prevented leukemia in transplanted NOD-SCID mice. Examination of 305 AML patients confirmed the correlation between PU.1 and JunB downregulation and suggests its relevance in human disease. These results delineate a transcriptional pattern that precedes the leukemic transformation in PU.1 knockdown HSC and demonstrate that decreased levels of c-Jun and JunB contribute to the development of PU.1-induced AML by blocking differentiation (c-Jun) and increasing self-renewal (JunB). Therefore, examination of disturbed gene expression in HSC can identify genes whose dysregulation is essential for leukemic stem cell function and are targets for therapeutic interventions. Experiment Overall Design: Total RNA of HSC of PU.1 knockdown or wildtype animals (3 pools of 3 animals each) was amplified by two rounds of RT and T7 promoter-based in-vitro transcription and the resultant biotinylated cRNA was then hybridized to Affymetrix Mouse Genome 430 2.0 arrays.
