Description
We report the global gene expression of mouse pancreatic cells in a pancreas-specific conditional knock-out mouse for Gata6, as compared with age-matched controls. Total RNA was extracted from the pancreas of 6-8 -week old mice of the two genotypes and analyzed. at this age, Gata6P-/- pancreata are histologically normal, but the acinar differentiation programme is already altered. we observe that loss of Gata6 causes the de-repression of ectopic non-pancreatic genes, as well as some genes involved in the mesenchymal programme. Overall design: mRNA extracted from the pancreas of 4 controls and 4 Gata6P-/- mice was sequenced.

Description
We demonstrate that Prnp dosage is critical for the maintenance of neuronal homeostasis since both its absence and, more relevantly, its overexpression induce higher sensitivity to kainate (KA) damage. These data correlate with electrophysiological results in freely behaving mutant mice showing an imbalance in activity-dependent synaptic processes, as determined from input/output curves, paired-pulse facilitation, and LTP studies. Gene expression profiling showed that 129 genes involved in canonical pathways such as Ubiquitination or Neurotransmission among others were co-regulated in knockout and PrPc overexpressing mice. RT-qPCR analysis of neurotransmission-related genes confirmed GABA-A and AMPA-Kainate receptor subunit transcriptional co-regulation in both Prnp -/- and Tg20 mice. Our results demonstrate that PrPc is necessary for the proper homeostatic functioning of hippocampal circuits, because of its interactions with GABAA and AMPA-Kainate receptors.

Description
We have found the existence of two independent populations contributing to the skin-resident macrophage pool based on their different origin. We have analyzed their gene profile by deep-sequencing (RNA-Seq). Analysis of RNA-Seq data revealed a differential expression signature between both subsets of skin macrophages for 744 of 17741 genes compiled (198 of them showing similar normalized expression levels across replicates). We have further characterized their specialized functions related to their different gene profiles. Overall design: Examination of gene profile of 2 different macrophage subsets coexisting in skin under steady state.

Description
Exposure to ultraviolet (UV) irradiation is the major cause of nonmelanoma skin cancer, the most common form of cancer in the United States. UV irradiation has a variety of effects on the skin associated with carcinogenesis, including DNA damage and effects on signal transduction. The alterations in signaling caused by UV regulate inflammation, cell proliferation, and apoptosis. UV also activates the orphan receptor tyrosine kinase and proto-oncogene Erbb2 (HER2/neu). In this study, we demonstrate that the UV-induced activation of Erbb2 regulates the response of the skin to UV. Inhibition or knockdown of Erbb2 before UV irradiation suppressed cell proliferation, cell survival, and inflammation after UV. In addition, Erbb2 was necessary for the UV-induced expression of numerous proinflammatory genes that are regulated by the transcription factors nuclear factor-kappaB and Comp1, including interleukin-1beta, prostaglandin-endoperoxidase synthase 2 (Cyclooxygenase-2), and multiple chemokines. These results reveal the influence of Erbb2 on the UV response and suggest a role for Erbb2 in UV-induced pathologies such as skin cancer.

Description
Human subjects were randomized for treatment with a GnRH-analogue, Goserelin, which suppresses endogenous testosterone or placebo for 12 weeks. Strength training was performed during the last 8 weeks. The suppression of testosterone resulted in an attenuation of the normal muscle adaptation to strength training (increased muscle mass and strength). To identify molecular signals involved in the response to testosterone levels, biopsies were obtained 4 hours after the last training session and gene expression compared with Affymetrix 3' microarrays. This timepoint should capture goserelin effect on both constitutive expression, training induced changes as well as acute exercise induced (4 hours) differences in mRNA levels.
Publication Title

Description
We applied RNA sequencing (RNA-seq) to map the global changes in gene expression of interscapular brown adipose tissue (iBAT) of mice subjected to acute cold exposure for 3 days. Here we find extensive changes in the iBAT transcriptome in response to cold with a prominent induction of genes associated to lipid-related metabolic processes. Overall design: RNA-seq of poly-A enriched RNA isolated from brown adipose tissue of 5 mice housed at room temperature (22°C) and 5 mice exposed to cold (4°C) for 3 days.

Description
Despite over 3,000 articles published on dystrophin in the last 15 years, the reasons underlying the progression of the human disease, differential muscle involvement, and disparate phenotypes in different species are not understood. The present experiment employed a screen of 12,488 mRNAs in 16-wk-old mouse mdx muscle at a time when the skeletal muscle is avoiding severe dystrophic pathophysiology, despite the absence of a functional dystrophin protein. A number of transcripts whose levels differed between the mdx and human Duchenne muscular dystrophy were noted. A fourfold decrease in myostatin mRNA in the mdx muscle was noted. Differential upregulation of actin-related protein 2/3 (subunit 4), beta-thymosin, calponin, mast cell chymase, and guanidinoacetate methyltransferase mRNA in the more benign mdx was also observed. Transcripts for oxidative and glycolytic enzymes in mdx muscle were not downregulated. These discrepancies could provide candidates for salvage pathways that maintain skeletal muscle integrity in the absence of a functional dystrophin protein in mdx skeletal muscle.
