Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We identified secreted frizzled-related protein-5 (Sfrp5) as a transcript that is upregulated during adipocyte differentiation and that is increased in white adipose tissue (WAT) of obese mice, compared to lean mice. To investigate the function of sFRP5 in adipose tissue biology, we studied sFRP5Q27stop mice, in which ENU mutagenesis was used to create a premature stop codon at Gln27, thereby creating a likely null allele.

Illumina HiSeq 2000
Description
about 250 genes were significantly changed after Gata4 and Gata6 were specifically deleted in the pancreatic progenitor cells Overall design: 6 pancreatic buds were pooled for the control, and 12 pancreatic buds were pooled for the Pdxcre; Gata4fl/fl; Gata6fl/fl. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq

Description
Hepatitis C virus (HCV) is widely used to investigate host-virus interactions and cellular responses to infection have been extensively studied in vitro. In human liver, interferon (IFN) stimulated gene expression can mask direct transcriptional responses to virus infection. To better characterize the direct effects of HCV infection in vivo, we analyze the transcriptomes of HCV-infected patients lacking an activated endogenous IFN system. We show that the expression changes observed in these patients predominantly reflect immune cell infiltrates rather than changes in cell-intrinsic metabolic pathways. We also investigate the transcriptomes of patients with endogenous IFN activation, which paradoxically cannot eradicate viral infection. We find that most IFN-stimulated genes (ISGs) are induced by both the endogenous IFN system and by recombinant IFN therapy, but with significantly higher induction levels in the latter. We conclude that the innate host immune response in chronic hepatitis C is too weak to clear the virus. Overall design: In this study, we aimed to disentangle the direct and indirect effects of HCV infection on cellular transcriptional profiles, by performing a detailed characterization of the gene expression changes associated with HCV infection, endogenous IFN system activation and pegIFNa treatment in the human liver. With this objective, we generated and analyzed high-throughput transcriptome sequencing profiles from liver biopsies derived from different categories of HCV-infected and non-infected patients, prior to and during treatment. First, to unveil HCV-induced cell-autonomous effects and to separate them from IFN-induced changes in the transcriptome, we selected liver biopsies from patients with chronic hepatitis C (CHC) without hepatic ISG induction, and compared them with un-infected control biopsies. Second, we examined the transcriptomic changes associated with the endogenous activation of the IFN system. Finally, we analyzed the gene expression changes resulting from pegIFNa/ribavirin treatment, by comparing transcriptome data from liver biopsies obtained before treatment and at different time points during the first week of therapy.

Description
We report the transcriptome changes that result of the genomic deletion of one or two alleles of an islet-specific long non-coding RNA (Blinc1) in isolated pancreas from e15.5 mouse embryos. Overall design: Pancreas from e15.5 embryos were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq.

Description
We identified 1,700 differentially expressed probesets in DKD glomeruli and 1,831 in diabetic tubuli; 330 probesets were commonly differentially expressed in both compartments. The canonical complement signaling pathway was determined to be statistically differentially regulated in both DKD glomeruli and tubuli and was associated with increased glomerulosclerosis even in an additional set of DKD samples.

Description
Aim:Transcriptional analysis of NKX2.2 knockdown versus control in human pancreatic islets Methods:Pancreatic islets from 3 human donors were transduced with an adenovirus encoding an shRNA directed against human NKX2.2 or a scrambled shRNA control. Total RNA was extracted.Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the human genome (Human: NCBI/build37.2)) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: Among the dysregulated genes with a p-value=0.05 are important genes for the maintenance of beta cell function and idenity. Conclusion: Nkx2.2 is a critical regulator of beta cell function and identity Overall design: mRNA profiles of the pancreatic islets from 3 human donors transduced with Ad.sh-NKX2.2 or scramble sh-RNA control vector were generated by deep sequencing , using Illumina HiSeq2000.
