Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
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

Illumina HiSeq 1500
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.

Description
This study was conducted to determine heterogeneity of cancer-associated fibroblasts (CAFs) in mammary tumors, by unsupervised analysis of single cell transcriptomes. Overall design: 768 single EpCAM-, CD45-, CD31- NG2- fibroblasts were isolated from mammary tumors of two 14 week old MMTV-PyMT mice. The cells were sequenced following the Smart-Seq2 protocol (Picelli et al. Nature Methods 2013).

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
Fine control of macrophage activation is required to prevent inflammatory disease, particularly at barrier sites such as the lung. However, the dominant mechanisms that regulate pulmonary MFs during inflammation are currently poorly understood. Here we show that airway MFs are substantially less able to respond to the canonical type-2 cytokine IL-4, which underpins allergic disease and parasite worm infections, than lung tissue or peritoneal cavity MFs. We reveal that MF hypo-responsiveness to IL-4 is dictated by the lung environment, though independent of the host microbiota or the prominent lung extracellular matrix components surfactant protein D and mucin 5b. Rather, compared to cavity MFs, airway MFs display severely dysregulated metabolism. Strikingly, upon removal from the lung, alveolar MFs regain IL-4 responsiveness in a process dependent upon glycolysis. Thus, we propose that impaired glycolysis within the pulmonary niche is a central determinant for regulation of MF responsiveness during type-2 inflammation. Overall design: The 13 analysed samples belong to 6 different groups, each group consisted of 2 or 3 samples. The groups consist of 3 separate macrophage populations, from either control or IL-4 complex treated mice. Each individual sample was generated from 3-5 pooled biological replicate mice.

Description
Cytokines have been shown to play a key role in the destruction of beta cells. In the rat insulinoma cell line (INS-1ab) overexpressing pancreatic duodenum homeobox 1 (Pdx1) increases sensitivity to Interleukin 1b (IL-1b). To elucidate mechanisms of action underlying Pdx1 driven potentiation of beta-cell sensitivity to IL-1, we performed a microarray analysis of INS-1ab cells with and without Pdx1 overexpression exposed to IL-1 between 2h and 24h.
