Description
By conditionally deleting BRD4 at various stages of thymic differentiation, we have established that BRD4 deficiency selectively affects a unique developmental subpopulation of thymocytes. Overall design: We examined by RNA-seq the effect on gene expression of BRD4 deletion in ex vivo DN, ISP, DP, CD4 and CD8 thymocyte subpopulations. The analysis was also performed on WT or BRD4 deleted ISP and DP thymocytes cultured for 16 hours at 37oC In this analysis, the conditional deletion of BRD4 (cKO) is achieved using the LCK-cre Transgene.

Description
SPT6, encoded by the SUPT6H in humans and Supt6 in mice, respectively, is a conserved histone chaperone that interacts with RNA polymerase II and participates in transcription elongation. However, the question of how SPT6 comes into play in transcriptional activation upon signaling, particularly in mammalian cells, has remained elusive. We investigated the contribution of SPT6 to interferon beta (IFNbeta) induced transcription in mouse NIH3T3 cells. IFNbeta triggers rapid and high level transcription of many IFN-stimulated genes (ISGs). We report here that SPT6 is recruited to ISGs after IFN stimulation. This recruitment was dependent on the interaction with the methyltransferase, NSD2. Further, siRNA-based SPT6 knockdown reduced levels of ISG activation. RNA-Seq analysis showed that SPT6 knockdown diminished about 50% of ISGs whose induction levels were higher than those unaffected by SPT6 knockdown. Under the tested conditions, SPT6 knockdown did not measurably change expression of constitutively expressed genes. This report highlights that SPT6 is recruited in a stimulus-dependent manner and elicits a major impact on signal induced transcription. Overall design: RNA-seq of NIH3T3 cells.

Description
Method: mRNA profiles were generated from pair-end sequencing of duplicate samples using Illumina Hiseq 2000. Results: Genes with an expression change of more than 2 fold were considered to be differentially expresed Overall design: Macrophages are cells belongs to innate immune system, which response to pathogen by the production of inflammatory proteins those that are effective in both combating pathogen and wound healing. Using microarray approach with BET inhibitors it was shown that many of the inflammatory response genes were under control of BET proteins. Purpose of this study was to assess the effect of BRD4 KO in NGS derived transcriptome profiles of both stimulated and unstimulated macrophages.

Description
Interleukin-21 (IL-21) is a pleiotropic cytokine that induces expression of transcription factor BLIMP1 (encoded by Prdm1), which regulates plasma cell differentiation and T cell homeostasis. We identified an IL-21 response element downstream of Prdm1 that binds the transcription factors STAT3 and IRF4, which are required for optimal Prdm1 expression. Genome-wide ChIP-Seq mapping of STAT3- and IRF4-binding sites showed that most regions with IL-21-induced STAT3 binding also bound IRF4 in vivo, and furthermore, revealed that the noncanonical TTCnnnTAA GAS motif critical in Prdm1 was broadly used for STAT3 binding. Comparing genome-wide expression array data to binding sites revealed that most IL-21-regulated genes were associated with combined STAT3-IRF4 sites rather than pure STAT3 sites. Correspondingly, ChIP-Seq analysis of Irf4_/_ T cells showed greatly diminished STAT3 binding after IL-21 treatment, and Irf4_/_ mice showed impaired IL- 21-induced Tfh cell differentiation in vivo. These results reveal broad cooperative gene regulation by STAT3 and IRF4.

Description
Background: SH-SY5Y cells exhibit a neuronal phenotype when treated with all-trans retinoic acid (RA), but the molecular mechanism of activation in the signaling pathway mediated by phosphatidylinositol 3-kinase (PI3K) is not sufficiently understood. To shed new light on the mechanism, we comprehensively compared the gene expression profiles between SK-N-SH cells and two subtypes of SH-SY5Y cells (SH-SY5Y-A and SH-SY5Y-E), each of which showed a different phenotype during RA-mediated differentiation. Results: SH-SY5Y-A cells differentiated in the presence of RA, whereas RA-treated SH-SY5Y-E cells required additional treatment with brain-derived neurotrophic factor (BDNF) for full differentiation. In combination with perturbation using a PI3K inhibitor, LY294002, we identified 386 genes and categorized them into two clusters dependent on the PI3K signaling pathway during RA-mediated differentiation in SH-SY5Y-A cells. Transcriptional regulation of the gene cluster was greatly reduced in SK-N-SH cells or partially impaired in SH-SY5Y-E cells in coincidence with a defect in the neuronal phenotype of these cell lines. Additional stimulation with BDNF induced a set of neural genes which were down-regulated in RA-treated SH-SY5Y-E cells but were abundant in the differentiated SH-SY5Y-A cells. Conclusions: We identified the gene clusters controlled by PI3K- and TRKB-mediated signaling pathways during differentiation in two subtypes of SH-SY5Y cells. TRKB-mediated bypass pathway compensates for the impaired neural functions generated by defects in several signaling pathways including PI3K in SH-SY5Y-E cells. The expression profiling data are useful for further studies to elucidate the signal transduction-transcriptional network including PI3K and/or TRKB.
