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.

Aim: Transcriptional analysis of the duodenum of adult Nkx2.2flox/SD;Villin-Cre (SDint) mice versus control Methods: 2 cm of the duodenum (as measured from the stomach) of 6 week old control and mutant mice 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. Results: 206 genes with a p-value <0.05 were significantly changed. Among these are some enteroendocrine hormones. Conclusion: The SD domain of Nkx2.2 regulates specification of some enteroendocrine cells Overall design: mRNA profiles of the duodenum of 6 week old control and SDint mice were generated by deep sequencing, in triplicate, using Illumina HiSeq2000.

Aim: Transcriptional analysis of the colon of adult Nkx2.2flox/flox;Villin-Cre (Nkx2.2int) mice versus control Methods: 2 cm of the colon (as measured after the caecum) of 6 week old control and mutant mice 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. Results: 53 genes with a p-value <0.05 were down-regulated and 36 were up-regulated. Among the changed genes are enteroendocrine hormones. Conclusion: Nkx2.2 regulates enteroendocrine cell specification Overall design: mRNA profiles of the colon of 6 week old control and Nkx2.2int mice were generated by deep sequencing, using Illumina HiSeq2000.

Description
Correlates of immune mediated protection to most viral and cancer vaccines are still unknown. This impedes the development of novel vaccines to incurable diseases such as HIV and cancer. In this study, we have used functional genomics and polychromatic flow cytometry to define the signature of the immune response to the yellow fever (YF) vaccine 17D (YF17D) in a cohort of forty volunteers followed for up to one year after vaccination. We show that immunization with YF17D leads to an integrated immune response that includes several effector arms of innate immunity including complement, the inflammasome and interferons, as well as adaptive immunity as shown by an early T cell response followed by a brisk and variable B cell response. Development of these responses is preceded, as demonstrated in three independent vaccination trials and in a novel in vitro system of primary immune responses (Modular IMmune In vitro Construct (MIMIC) system), by the coordinated up-regulation of transcripts for specific transcription factors including STAT1, IRF7 and ETS2 that are upstream of the different effector arms of the immune response. These results clearly show that the immune response to a strong vaccine is preceded by coordinated induction of masters transcription factors, that lead to the development of a broad, polyfunctional and persistent immune response that integrates all effector cells of the immune system.

Description
Regulatory T (Treg) cells are involved in self tolerance, immune homeostasis, prevention of autoimmunity, and suppression of immunity to pathogens or tumours. The forkhead transcription factor FOXP3 is essential for Treg cell development and function as mutations in FOXP3 cause severe autoimmunity in mice and humans. However, the FOXP3-dependent molecular mechanisms leading to this severe phenotype are not well understood. Here we introduce the chromatin remodelling enzyme SATB1 (special AT-rich sequence-binding protein-1) as an important target gene of FOXP3. So far, SATB1 has been associated with normal thymic T-cell development, peripheral T-cell homeostasis, TH1/TH2 polarization, and reprogramming of gene expression. In natural and induced murine and human FOXP3+ Treg cells SATB1 expression is significantly reduced. While there is no differential epigenetic regulation of the SATB1 locus between Treg and Teffector cells, FOXP3 reduces SATB1 expression directly as a transcriptional repressor at the SATB1 locus and indirectly via miR-155 induction, which specifically binds to the 3UTR of the SATB1 mRNA. Reduced SATB1 expression in FOXP3+ cells achieved either by overexpression or induction of FOXP3 is linked to significant reduction in TH1 and TH2 cytokines, while loss of FOXP3 function either by knock down or genetic mutation leads to significant upregulation of SATB1 and subsequent cytokine production. Alltogether, these findings demonstrate that reduced SATB1 expression in Treg cells is necessary for maintenance of a Treg-cell phenotype in vitro and in vivo and places SATB1-mediated T cell-specific modulation of global chromatin remodelling central during the decision process between effector and regulatory T-cell function.

Repression of the genome organizer SATB1 in regulatory T cells is required for suppressive function and inhibition of effector differentiation.

Description
To investigate the role of CYP2B in lipid metabolism, a Cyp2b triple knockout mouse lacking Cyp2b9, Cyp2b10, and Cyp2b13 was developed using CRISPER/Cas9. Wildtype (WT) and Cyp2b-null mice were fed a normal diet (ND) or a 60% high-fat diet (HFD) for 10 weeks. RNA was extracted from the livers of male and female mice from all treatment groups and used for RNA seqencing. RNAseq data demonstrated that hepatic gene expression in ND-fed Cyp2b-null male mice is similar to HFD-fed WT mice, indicating that Cyp2b-null male mice are reacting as if they are receiving a HFD even if they are not. Gene ontology and KEGG pathways show perturbations in lipid metabolism pathways, including PUFA metabolism, fatty acid elongation, and glycerophospholipid metabolism. Overall design: Use RNA-sequencing to investigate the role of Cyp2b in hight-fat diet-induced obesity on a transcriptomic level, by comparing the livers of WT and Cyp2b-null mice fed a HFD for 10 weeks using Illumina technology.
Publication Title
