Description
Gene expression was assessed in a cohort of 40 choroid plexus tumors isolated from fresh-frozen tissue. We investigated unique expression patterns among tumor subgroups and refined the classification of choroid plexus tumors according to gene expression intensities.

Description
Super-enhancers (SEs) are large clusters of transcriptional enhancers that are co-occupied by multiple lineage specific transcription factors driving expression of genes that define cell identity. In embryonic stem cells (ESCs), SEs are highly enriched for Oct4, Sox2, and Nanog in the enhanceosome assembly and express enhancer RNAs (eRNAs). We sought to dissect the molecular control mechanism of SE activity and eRNA transcription for pluripotency and reprogramming. Starting from a protein interaction network surrounding Sox2, a key pluripotency and reprogramming factor that guides the ESC-specific enhanceosome assembly and orchestrates the hierarchical transcriptional activation during the final stage of reprogramming, we discovered Tex10 as a novel pluripotency factor that is evolutionally conserved and functionally significant in ESC self-renewal, early embryo development, and reprogramming. Tex10 is enriched at SEs in a Sox2-dependent manner and coordinates histone acetylation and DNA demethylation of SEs. Our study sheds new light on epigenetic control of SE activity for cell fate determination. Overall design: RNA sequencing analysis was performed in mouse embryonic stem cells with Luciferase and Tex10 knockdown. RNA-seq Experiments were carry out in two biological replicates.

Description
Memory B cells play essential roles in the maintenance of long-term immunity and may be important in the pathogenesis of autoimmune disease, but how these cells are distinguished from their nave precursors is poorly understood. To address this, it would be important to understand how gene expression differs between memory and naive B cells in order to elucidate memory-specific functions. Using model systems that help overcome the lack of murine memory-specific markers and the low frequency of antigen-specific memory and nave cells, we undertook a global comparison of gene expression between memory B cells and their naive precursors.
Publication Title
Systematic comparison of gene expression between murine memory and naive B cells demonstrates that memory B cells have unique signaling capabilities.

Description
Memory B cell responses are more rapid and of greater magnitude than are primary antibody responses. The mechanisms by which these secondary responses are eventually attenuated remain unknown. We demonstrate that the transcription factor ZBTB32 limits the rapidity and duration of antibody recall responses. ZBTB32 is highly expressed by mouse and human memory B cells, but not by their nave counterparts. Zbtb32-/- mice mount normal primary antibody responses to T-dependent antigens. However, Zbtb32-/- memory B cell-mediated recall responses occur more rapidly and persist longer than do control responses. Microarray analyses demonstrate that Zbtb32-/- secondary bone marrow plasma cells display elevated expression of genes that promote cell cycle progression and mitochondrial function relative to wild-type controls. BrdU labeling and adoptive transfer experiments confirm more rapid production and a cell-intrinsic survival advantage of Zbtb32-/- secondary plasma cells relative to wild-type counterparts. ZBTB32 is therefore a novel negative regulator of antibody recall responses.

Description
Purpose: The goal of this study is to compare the transcriptional phenotype of lymphoid and kidney-infiltrating T cell populations in the setting of systemic inflammatory disease to determine how tissue location alters their phenotype. Methods: mRNA profiles of T cells isolated from 23-week-old nephritic (protein score of 3+ on dipstick) mice were used in this study. T cells were isolated by flow cytometry gated on CD45+Thy1.1+CD44+ and either CD4 or CD8+ T cells. RNA was isolated using the RNeasy Plus Micro Kit (Qiagen). Samples were sequenced using Illumina NextSeq 500 with 75bp paired-end reads and aligned to the mm10 genome using the STAR aligner. The number of uniquely aligned reads ranged from 10 to 12 million. Using an optimized data analysis workflow, Gene-level counts were determined using featureCounts and raw counts were analyzed for differential expression using the “voom” method in the “limma” R package. Results: After determining genes that were differentially expressed between splenic T cells and KIT, we performed gene set enrichment analysis (GSEA. Differentially expressed genes were compared to several previously defined gene signatures that are characteristic of CD8+ and CD4+ T cell exhaustion in the chronic LCMV infection model and tumor infiltrating lymphocytes. Genes from the CD8+ exhaustion cluster were significantly enriched among genes that were differentially expressed in CD8+ KITs vs CD8+ splenocytes. Overall design: mRNA profiles of CD4 and CD8 T cells from spleen and kidney of 23 week old wild MRL/lpr mice were generated in triplicate by sequencing using Illumina NextSeq 500
