Description
TRF2 is a paralogue of TATA-box binding protein (TBP) with highest expression in testis. Although Trf2 inactivation in mice leads to arrested spermatogenesis, there is no direct evidence that Trf2 is recruited to chromatin to directly regulate gene expression. We used genetically modified mice where endogenous Trf2 has been modified to carry a TAP-TAG to perform ChIP-reChIP followed by deep sequencing. We found that Trf2 is recruited to all active promoters as a subunit of TFIIA/ALF complex together with TBP. To assess the effect of Trf2 inactivation on gene expression we performed RNA-seq on WT and Trf2-/- testes at 21 days of age when haploid cell gene expression is activated. Overall design: The testes from three 21 day old WT and three Trf2-/- males were taken to prepare total RNAs for deep sequencing.

Description
Our goal was to identify early genetic changes in the development of autoimmune dysfunction. WT and IL-2-KO CD8 T cells were sorted from the lymph node and spleen of 12-day old mice. Total RNA was isolated by Expression Analysis Inc. using Illumina TrueSeq Stranded Total RNA Sample Preparation Kit. Eight samples were sequenced (four biological replicates of IL-2-KO and WT/HET mice), producing 2X50 paired-end reads using the Illumine HiSeq 2500 platform. Raw reads were provided by Expression Analysis. We identified several genetic signatures within the bulk data including a cytolyic pattern and a novel gene expression pattern indicating a helper-like function. Overall design: WT and IL-2-KO CD8 T cells were sorted from the lymph node and spleen of 12-day old mice. Total RNA was isolated by Expression Analysis Inc. using Illumina TrueSeq Stranded Total RNA Sample Preparation Kit. Eight samples were sequenced (four biological replicates of IL-2-KO and WT/HET mice).

Description
Serrated adenocarcinomas are morphologically different from conventional adenocarcinomas. The serrated pathway has recently been proposed to represent a novel mechanism of colorectal cancer (CRC) formation. However, whether they are biologically different and truly form a distinct subclass of CRC, is not known. This study shows that the gene expression profile of serrated and conventional CRCs differs from each others and that serrated CRCs are not only morphologically novel, but also biologically distinct subclass of CRC.

Description
Innate immune memory is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components such as LPS. We apply an integrated epigenomic approach to characterize the molecular events involved in LPS-induced tolerance in a time dependent manner. ChIP-seq, RNA-seq, WGBS and ATAC-seq data were generated. This analysis identified epigenetic programs in tolerance and trained macrophages, and the potential transcription factors involved. Overall design: Time-course in vitro culture of human monocytes. Two innate immune memory states can be induced in culture through an initial exposure of primary human monocytes to either LPS or BG for 24 hours, followed by removal of stimulus and differentiation to macrophages for an additional 5 days. Cells were collected at baseline (day 0), 1 hour, 4 hour, 24 hour and 6 days.

Description
Bipolar disorder (BD) is a highly heritable and heterogeneous mental illness whose manifestations often include impulsive and risk-taking behavior. This particular phenotype suggests that abnormal striatal function could be involved in BD etiology, yet most transcriptomic studies of this disorder have concentrated on cortical brain regions. We report the first transcriptome profiling by RNA-Seq of the human dorsal striatum comparing bipolar and control subjects. Differential expression analysis and functional pathway enrichment analysis were performed to identify changes in gene expression that correlate with BD status. Further co-expression and enrichment analyses were performed to identify sets of correlated genes that show association to BD. Overall design: Total RNA samples were isolated from 36 postmortem dorsal striatum subjects (18 bipolar and 18 control) and sequenced. One outlier sample was removed and 35 samples (18 bipolar and 17 control) were analyzed.
Publication Title
Transcriptome sequencing implicates dorsal striatum-specific gene network, immune response and energy metabolism pathways in bipolar disorder.

Description
Duchenne Muscular Dystrophy (DMD) is a fatal muscle wasting disorder caused by dystrophin deficiency. Previous work suggested that increased expression of the dystrophin-related protein utrophin in the mdx mouse model of DMD can prevent dystrophic pathophysiology. Physiological tests showed that the transgenic mouse muscle functioned in a way similar to normal muscle. More recently, it has become possible to analyse disease pathways using microarrays, a sensitive method to evaluate the efficacy of a therapeutic approach. We thus examined the gene expression profile of mdx mouse muscle compared to normal mouse muscle and compared the data with that obtained from the transgenic line expressing utrophin. The data confirm that the expression of utrophin in the mdx mouse muscle results in a gene expression profile virtually identical to that seen for the normal mouse. This study confirms that a strategy to up-regulate utrophin is likely to be effective in preventing the disease.

Description
Developmental morphogenesis, tissue injury, and oncogenic transformation can cause the detachment of epithelial cells. These cells are eliminated by a specialized form of apoptosis (anoikis). While the processes that contribute to this form of cell death have been studied, the underlying mechanisms remain unclear. Here we tested the role of the cJUN NH2-terminal kinase (JNK) signaling pathway using murine models with compound JNK-deficiency in mammary and kidney epithelial cells. These studies demonstrated that JNK is required for efficient anoikis in vitro and in vivo. Moreover, JNK-promoted anoikis required pro-apoptotic members of the BCL2 family of proteins. We show that JNK acts through a BAK/BAX-dependent apoptotic pathway by increasing BIM expression and phosphorylating BMF leading to death of detached epithelial cells. Overall design: In order to understand the role of the JNK pathway in anoikis, Rosa-CreER (Control) and Jnk1flox/flox Jnk2-/- Rosa-CreER (Jnk1-/-Jnk2-/-) cells were grown as attached monoloayers or suspended for 4 hours. RNA was isolated from these cells and subjected to RNASeq to measure differential gene expression. Three separate samples from each condition were analyzed.

Description
The epicardium, an epithelium covering the heart, is essential for cardiac development. During embryogenesis, the epicardium provides instructive signals for the growth and maturation of cardiomyocytes and for coronary angiogenesis. We generated an in vitro model of human embryonic epicardium derived from human pluripotent stem cells (hPSC-epi). These cells were able to differentiate into cardiac fibroblasts (cf) and smooth muscle cells (smc) in vitro (hPSC-epi-cf and hPSC-epi-smc respectively). Furthermore, we showed that they improved maturation of hPSC-derived cardiomyocytes (hPSC-cardio) in vitro while neural crest cells derived from hPSC (hPSC-NC) could not. Furthermore, they improved survival of hPSC-cardio and stimulated angiogenesis when injected in a rat model of myocardium infarction. We performed mRNA sequencing of the hPSC-epi, hPSC-epi-cf, hPSC-smc and hPSC-NC in order to identify the secreted molecules specifically produced by the hPSC-epi and/or its derivatives in comparison with the hPSC-NC. Vascular smooth muscle cells have different embryonic origins and different properties depending on their location in the body. The coronary smooth muscle cells come from the epicardium while the aortic ones come from the mesoderm or the neural crest. We performed mRNA sequencing of human coronary artery smc and human aortic smc to identify a specific signature of the coronary smc. We also compared the genes expressed in the hPSC-epi-smc and the smc derived from hPSC-derived lateral plate mesoderm. Overall design: For hPSC-derived samples the three replicates are coming from three different in vitro differentiations from H9. For the human primary cells, the triplicates are technical replicates (three different wells from the same culture at the same passage)
