Description
Purpose: The goals of this study are to compare in vitro polarized T helper 17 cell transcriptome profiling (RNA-seq) in the presence or absence of recombinant murine SAA1 Methods: Th17 mRNA profiles of 96hrs in vitro cultured T helper 17 cells treated with vehicle or recombinant murine SAA1 were generated by deep sequencing, using Illumina RapidRun. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) and TopHat followed by CuffDiff. qRT–PCR validation was performed using SYBR Green assays. Results: 177 genes were changed more than 2 folds in the presence of recombinant murine SAA1. Conclusions: Our study suggest that SAA1 could augment subset of Th17 transcription program in vitro. Overall design: mRNA profiles of 48hr in vitro cultured Th17 from wild type (WT) mice were generated by deep sequencing using Illumina RapidRun.

Purpose: The goals of this study are to compare mRNAs expressed by Th17 cells and ILC3s in small intestine of lamina propria of mice. Methods: Small intestine were digested with collagenase, dispase, and DNase. Percoll enriched lamina propria Th17 and ILCs sorted by BD ARIA II. Total RNA were harvested and sequencing were performe. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) and TopHat followed by CuffDiff. qRT–PCR validation was performed using SYBR Green assays. Results: Small intestine Th17 cells and ILCs exhibit differential gene expression profiles. Overall design: compare mRNAs expressed by Th17 cells and ILC3s in small intestine of lamina propria of mice.

Description
Regulatory T cells (Treg cells) expressing the forkhead family transcription factor Foxp3 are critical mediators of dominant immune tolerance to self. Most Treg cells constitutively express the high-affinity interleukin 2 (IL-2) receptor alpha-chain (CD25); however, the precise function of IL-2 in Treg cell biology has remained controversial. To directly assess the effect of IL-2 signaling on Treg cell development and function, we analyzed mice containing the Foxp3gfp knock-in allele that were genetically deficient in either IL-2 (Il2-/-) or CD25 (Il2ra-/-). We found that IL-2 signaling was dispensable for the induction of Foxp3 expression in thymocytes from these mice, which indicated that IL-2 signaling does not have a nonredundant function in the development of Treg cells. Unexpectedly, Il2-/- and Il2ra-/- Treg cells were fully able to suppress T cell proliferation in vitro. In contrast, Foxp3 was not expressed in thymocytes or peripheral T cells from Il2rg-/- mice. Gene expression analysis showed that IL-2 signaling was required for maintenance of the expression of genes involved in the regulation of cell growth and metabolism. Thus, IL-2 signaling seems to be critically required for maintaining the homeostasis and competitive fitness of Treg cells in vivo.

Description
Trimethylated histone H3-lysine 4 is primarily distributed in the form of sharp peaks, extending in neuronal chromatin on average only across 500-1500 base pairs mostly in close proximity to annotated transcription start sites. To explore whether H3K4me3 peaks could also extend across much broader domains, we undertook a detailed analysis of broadest domain cell-type specific H3K4me3 peaks in ChIP-seq datasets from sorted neuronal and non-neuronal nuclei in human, non-human primate and mouse prefrontal cortex (PFC), and blood for comparison. Overall design: We collected separately cortical gray (GM) and subcortical white matter (WM) from 6 adult human subjects without neurological disease and extracted total RNA processed by the RNA-Seq approach.

Description
PPARg and C/EBPa cooperate to control preadipocyte differentiation (adipogenesis). However, the factors that regulate PPARg and C/EBPa expression during adipogenesis remain largely unclear. Here we show PTIP, a protein that associates with histone H3K4 methyltransferases, regulates PPARg and C/EBPa expression in mouse embryonic fibroblasts (MEFs) and during preadipocyte differentiation. PTIP deletion in MEFs leads to marked decreases of PPARg expression and PPARg-stimulated C/EBP expression. Further, PTIP is essential for induction of PPARg and C/EBPa expression during preadipocyte differentiation. Deletion of PTIP impairs the enrichment of H3K4 trimethylation and RNA polymerase II on PPARg and C/EBPa promoters. Accordingly, PTIP-/- MEFs and preadipocytes all show striking defects in adipogenesis. Furthermore, rescue of the adipogenesis defect in PTIP-/- MEFs requires co-expression of PPARg and C/EBPa. Finally, deletion of PTIP in brown adipose tissue significantly reduces tissue weight in mice. Thus, by regulating PPARg and C/EBPa expression, PTIP plays a critical role in adipogenesis.

Description
Fetal asphyctic (FA) preconditioning is effective in attenuating brain damage incurred by a subsequent perinatal asphyctic insult. Unraveling mechanisms of this endogenous neuroprotection, activated by FA preconditioning, is an important step towards new clinical strategies for asphyctic neonates. Genomic reprogramming is thought to be, at least in part, responsible for the protective effect of preconditioning. Therefore, we investigated whole genome differential expression in the preconditioned rat brain.
