Description
Mycobacterium avium infection in mice induces granuloma necrosis in the lung which is dependent on IFNg. IRF1 is a transcription factor activated by IFNg signaling. The effect of IFNg and IRF1 on immunopathology and transcriptional changes in the lung were analysed using gene-deficient mice.

Description
We analyzed anti-proliferative dominant-negative Brd4 mutants that compete with the function of distinct Brd4 domains. We used these Brd4 mutants to compare the Brd4-specific transcriptome with the transcriptome of JQ1 treated cells. Overall design: We performed polyA RNA-seq of Raji cells expressing Brd4 constructs f3 and f9 (dnBrd4_f3/f9) and Raji cell expressing the luciferase control vector treated with JQ1 (luc_JQ1) or DMSO as control (luc_DMSO).
Publication Title
Transcriptome analysis of dominant-negative Brd4 mutants identifies Brd4-specific target genes of small molecule inhibitor JQ1.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Here we demonstrate by the use of extensive controls and stringent statistical analysis that dendritic cells differentially regulate hundreds of different genes based upon sequence similarity of endogenously- and exogenously-loaded antigens and in a T-cell independent fashion. When endogenously and exogenously-derived antigens are identical, dendritic cells upregulate many different components of the Th-1 response, favoring the priming of CD8+ effectors and promulgating cellular immunity.
Publication Title
Th-1 polarization is regulated by dendritic-cell comparison of MHC class I and class II antigens.

Description
Mesenchymal stromal cells are a critical component of the bone marrow hematopoietic stem cell niche. In myelofibrosis, these cells are the major source of fibrosis in the bone marrow. We performed gene expression analysis using microarrays to systematically elucidate the mechanisms leading to fibrogenic conversion of these cells.

Description
Metastatic relapse of breast cancer and other tumor types usually occurs several years after surgical resection of the primary tumor. Early dissemination of tumor cells followed by an extended period of dormancy is thought to explain this prevalent clinical behavior. By using a gain-of-function retroviral cDNA screen in the mouse, we found that Coco, a secreted antagonist of TGF-beta ligands, induces solitary mammary carcinoma cells that have extravasated in the lung stroma to exit from dormancy. Mechanistic studies demonstrate that Coco awakens dormant metastasis-initiating cells by blocking stroma-derived Bone Morphogenetic Proteins. Inhibition of canonical BMP signaling reverses the commitment to differentiation of these cells and enhances their self-renewal and tumor-initiation capacity. Expression of Coco induces a discrete gene expression signature strongly associated with metastatic relapse to the lung but not to the bone or brain in primary patients samples. Accordi ngly, silencing of Coco does not inhibit metastasis to the bone or brain in mouse models. These findings suggest that metastasis-initiating cells require the self-renewal capability typically associated with stem cells in order to exit from dormancy and identify Coco as a master regulator of this process.

Description
Human T-cell Acute lymphoblastic Leukemia cell line CEM was transfected with either shRNA against ZMIZ1 or scrambled shRNA. Four (non-paired) biological replicates of each condition had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. A supplementary Excel workbook holding the same processed data as the series matrix file is provided, with some probe set annotation, and a simple statistical comparison. The raw (.CEL) files are also provided.

Description
Enterocytes assemble dietary lipids into chylomicron particles that are taken up by intestinal lacteal vessels and peripheral tissues. Although chylomicrons are known to assemble in part within membrane secretory pathways, the modifications required for efficient vascular uptake are unknown. We report that the transcription factor Pleomorphic adenoma gene-like 2 (PLAGL2) is essential for this aspect of dietary lipid metabolism. PlagL2-/- mice die from post-natal wasting owing to failure of fat absorption. Lipids modified in the absence of PlagL2 exit from enterocytes but fail to enter interstitial lacteal vessels. Dysregulation of enterocyte genes closely linked to intracellular membrane transport identified candidate regulators of critical steps in chylomicron assembly. PlagL2 thus regulates essential and poorly understood aspects of dietary lipid absorption and its deficiency represents an authentic animal model with implications for amelioration of obesity or the metabolic syndrome.
Publication Title
Loss of the PlagL2 transcription factor affects lacteal uptake of chylomicrons.

Description
Host defense by the innate immune system requires the establishment of antimicrobial states allowing cells to cope with microorganisms before the onset of the adaptive immune response. Interferons (IFN) are of vital importance in the establishment of cell-autonomous antimicrobial immunity. Speed is therefore an important attribute of the cellular response to IFN. With much of the antimicrobial response being installed de novo, this pertains foremost to gene expression, the rapid switch between resting-state and active-state transcription of host defense genes. Our results show how mRNA expression changes upon IFNb or IFNg treatment in wild typ and Irf9-/- bone marrow derived macrophages. Overall design: Methods: Bone marrow derived macrophage mRNA of wild-type (WT) and Irf9 knock out mice (IRF9-/-) untreated, as well as 2h IFNb and IFNg treated were generated by deep sequencing, in triplicate, using Illumina sequencing.
