Description
We collected and compared samples from the cohort consisted of six groups as follows: methotrexate (MTX) monotherapy, combination therapy of MTX and infliximab (IFX), tocilizumab (TCZ) monotherapy, age- and gender-matched HC, and a small number of synovial fluid samples. In order to reduce variation due to the proportion of cells at each developmental stage, we performed transcriptome analysis after sorting CD4+ and CD8+ T cells according to developmental stage. We created a gene list that was significantly expressed in RA T cells, and revealed that pathways such as mTORC1, IL-2-stat5, Cell cycle and interferon-related genes were significantly enriched among them. Overall design: Examination among healthy controls and patients with rheumatoid arthritis, including before and after treatment

Description
We compared whole CD4+ and CD8+ T cells from frozen PBMC samples that were collected before and after treatment initiation of each patient with rheumatoid arthritis. Lists consisting of 858 and 950 differentially expressed genes were created from CD4 and CD8, respectively, and these were used for enrichment analysis. As a result, we found that certain pathways were downregulated after TCZ treatment in both CD4+ and CD8+ T cells, including mechanistic target of rapamycin complex 1 (mTORC1) signaling, the IL-2 pathway, and IFN-related genes. Overall design: Examination between before and after tocilizumab treatment of CD4 and CD8 T cell in rheumatoid arthritis patients

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We identify sites of combinatorial control by performing high throughput ChIP experiments on p300, CREB-binding protein (CBP), the deacetylase SIRT1 and on multiple DNA-binding transcription factors in three different tissues. We present a quantitative model of transcriptional regulation that reveals the contribution of each binding site to tissue-specific gene expression in several mouse cell types. Binding to both evolutionarily conserved and non-conserved sequences is found to contribute significantly to transcriptional regulation. We demonstrate that binding location strongly predicts the expression level of nearby genes.

Description
Cellular dedifferentiation signifies the withdrawal of cells from a specific differentiated state into a stem cell-like undifferentiated state. However, the mechanism of dedifferentiation remains obscure. We showed that follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency.

Description
To identify the “time-lapse” TF networks during B lineage commitment, we established multipotent progenitors harboring a tamoxifen-inducible form of Id3, an in vitro system where virtually all cells became B cells within 6 days by simply withdrawing 4-OHT. In this study, transcriptome analysis at multiple time points was performed using the culture system. Overall design: Time-course transcriptomic profiles of multipotent iLS cells toward B committed cells were analyzed by deep sequencing, basically in triplicate, using Illumina Hiseq platform.
Publication Title
Three-step transcriptional priming that drives the commitment of multipotent progenitors toward B cells.

Description
Specific bile acids are potent signaling molecules that modulate metabolic pathways affecting lipid, glucose and bile acid homeostasis, and the microbiota. Bile acids are synthesized from cholesterol in the liver, and the key enzymes involved in bile acid synthesis (Cyp7a1, Cyp8b1) are regulated transcriptionally by the nuclear receptor FXR. We have identified an FXR-regulated pathway upstream of a transcriptional repressor that controls multiple bile acid metabolism genes. We identify MafG as an FXR target gene and show that hepatic MAFG overexpression represses genes of the bile acid synthetic pathway and modifies the biliary bile acid composition. In contrast, loss-of-function studies using MafG(+/-) mice causes de-repression of the same genes with concordant changes in biliary bile acid levels. Finally, we identify functional MafG response elements in bile acid metabolism genes using ChIP-seq analysis. Our studies identify a molecular mechanism for the complex feedback regulation of bile acid synthesis controlled by FXR

Description
Chromatin modifying activities for construction of appropriate epigenetic landscapes by polycomb repressive complex 2 (PRC2) play an essential role in development and tumorigenesis. However, the spatiotemporal mechanisms by which PRC2 achieves diverse epigenomes for specific tissue or cellular contexts remain poorly understood. Here, we discovered that LATS2 knockout causes dysregulation of PRC2 and subsequent transcriptome changes for differentiation in both mouse and human cells. LATS2 depletion dependent dysregulation of PRC2 also effects H3K4me3 and forms negative feedback loop for maintenance of PRC2. Further analyses reveal that LATS2 on chromatin binds to EZH2 and LATS2 has ability to phosphorylate PRC2 in vitro. These LATS2 dependent H3K27me3 targets are highly induced during neurogenesis, and statistical analysis of glioblastoma multiforme reveals that LATS2-high cases show more dedifferentiated transcriptome and poor prognosis with silencing of H3K27me3 targets. These observations suggest that LATS2-mediated epigenome coordination is pivotal for development and disease, including cancer. Overall design: mRNA of LATS2 KO HeLa-S3 cells rescued by empty vector, wild-type LATS2 or kinase-dead LATS2 were subjected to deep sequencing profiling using Illumina HiSeq 2500
