Description
Lamina propria and muscularis macrophages, were sorted at steady steate and 2h after oral exposure to an attenuated form of Salmonella, comparison among these populations showed that the muscularis macrophages quckly respond to the presence of intestinal bacteria, upregulating some important tissue protective genes. Overall design: intestinal macrophages from 3 mice were pooled into one RNA sample, the experiment was done control X infected and was repeated twice

Description
Models for tumorigenesis can be made by transforming normal cells with defined genetic elements. This allows us to determine that adrenocortical tumor development and progression follows a multistep model. Morever, we demonstrated that the order of genetic events has a great consequence on the phenotype of the resultant tumor. We performed transcriptomic analysis using cDNA microarrays to identify the molecular signature that might explain the distinctive in vivo phenotypes observed in response to both orders of the mutational events.

Description
Utilizing glycerol and cardiotoxin (CTX) injections in the tibialis anterior muscles of M. musculus provides models of skeletal muscle damages followed by skeletal muscle regeneration. In particular, glycerol-induced muscle regeneration is known to be associated with ectopic adipogenesis. We characterized genome-wide expression profiles of tibialis anterior muscles from wild-type mice injured by either glycerol or CTX injection. Our goal was to detect gene expression changes during the time course of glycerol-induced and CTX-induced muscle regeneration models, that can lead to ectopic adipocyte accumulation.

Description
In the present study we have studied the mechanistic and functional aspects of NCoR1 function in mouse skeletal muscle. NCoR1 muscle-specific knockout mice exhibited an increased oxidative metabolism. Global gene expression analysis revealed a high overlap between the effects of NCoR1 deletion and peroxisome proliferator-activated receptor (PPAR) gamma coactivator 1alpha (PGC-1alpha) overexpression on oxidative metabolism in skeletal muscle. The repressive effect of NCoR1 on oxidative phosphorylation gene expression specifically antagonizes PGC-1alpha-mediated coactivation of ERRalpha. We therefore delineated the molecular mechanism by which a transcriptional network controlled by corepressor and coactivator proteins determines the metabolic properties of skeletal muscle, thus representing a potential therapeutic target for metabolic diseases.

Description
During mammalian gastrulation, pluripotent epiblast stem cells migrate through the primitive streak to form the multipotent progenitors of the mesoderm and endoderm germ layers. Msgn1 is a bHLH transcription factor and is a direct target gene of the Wnt/bcatenin signaling pathway. Msgn1 is expressed in the mesodermal compartment of the primitive streak and is necessary for the proper development of the mesoderm. Msgn1 mutants show defects in somitogenesis leading to a lack of trunk skeletal muscles, vertebra and ribs.

Description
Thymic stromal lymphopoietin (TSLP) is a type I cytokine that plays a central role in induction of allergic inflammatory responses. Its principal targets have been reported to be dendritic cells and / or CD4 T cells; epithelial cells are a principal source. We report here the development of a reporter mouse (TSLP-ZsG) in which a ZsGreen (ZsG)-encoding construct has been inserted by recombineering into a bacterial artificial chromosome (BAC) immediately at the translation initiating ATG of TSLP. The expression of ZsG by mice transgenic for the recombinant BAC appears to be a faithful surrogate for TSLP expression, particularly in keratinocytes and medullary thymic epithelials cells (mTECs). A comparison of gene expression in ZsG expressing and ZsG negative mTECs and cortical thymic epithelial cells, which are all ZsG negative, revealed that all three populations can be distinguished from one another. In particular ZsG (and TSLP) expressing mTECs and ZsG- mTECs are separable populations based on gene expression profiling. Little or no expression of ZsG is observed in bone marrow-derived mast cells or basophils or in CD45+ cells infiltrating TSLP/ZsG-expressing skin. Using the TSLP-ZsG reporter mouse, we show that TNFa and IL-4/IL-13 are potent inducers of TSLP expression by keratinocytes and that local activation of Th2 and Th1 cells induces keratinocyte TSLP expression. We suggest that the capacity of TSLP to both induce Th2 differentiation and to be induced by activated Th2 cells raises the possibility that TSLP may be involved in a positive feedback loop to enhance allergic inflammatory conditions.

Description
Germline BRCA1 or BRCA2 mutations (mtBRCA1 and mtBRCA2) dramatically increase risk for high-grade serous ovarian cancer (HGSOC), the most commonly diagnosed histotype. Other risk factors for this cancer, which originates primarily in the distal fallopian tube epithelium (FTE), implicate ovulation. To test whether mtBRCA1 or mtBRCA2 FTE cells respond differently to peri-ovulatory follicular fluid (FF) exposure than control patient FTE, gene expression profiles from primary FTE cultures were compared at baseline, 24h after FF exposure, and 24h after FF replacement with culture medium. Hierarchical clustering revealed both FF exposure and BRCA mutation status affect gene expression, with BRCA1 mutation having the greatest impact. Analysis revealed increased NFB and EGFR signaling at baseline, with increased interferon signaling after recovery from FF exposure in mtBRCA1 samples. Inhibition of EGFR signaling and ISGylation by increased BRCA1 expression was verified in an immortalized FTE cell line, OE-E6/E7, stably transfected with BRCA1. Suppression of ISG15 and ISGylated protein levels by BRCA1 expression was found to be mediated by decreased NFB signaling and was transiently suppressed by FF exposure. This study demonstrates increased NFB signaling associated with decreased BRCA1 expression resulting in increased ISG15 and ISGylation following FF exposure, which could represent potential targets for chemoprevention.

Description
The quantitative deep bulk MARS-seq analysis demonstrated that DCs from ICAM-1/2 double knockout (DKO) chimeric LNs display similar transcriptomes to those of WT DCs in both their resting and CD40 mAb activated states. Overall design: Transciptome analysis of activated and resting classical DCs from either WT or ICAM-1/2 DKO chimeric mice was performed. DC cells were isolated from popliteal lymph nodes and sorted according to the following markers: CD45, CD11c and MHC-II
