Purpose: The goals of this study were to identify preferential gene expression signatures that are unique to Tregs in neonatal skin relative to peripheral Tregs Methods: Tregs from telogen skin and SDLNs were purified by cell sorting (using the Treg GFP reporter mouse line Foxp3-DTR/GFP) to generate mRNA transcription profiles. Results: Transcriptional profiling revealed a unique neonatal skin Treg signature relative to SDLN Tregs Conclusion: Our study represents the first detailed analysis of the neonatal skin Treg transcriptome. Overall design: mRNA profiles of skin and SDLN Tregs isolated from 13 day old Foxp3-DTR/GFP mice.

View SamplesBipolar disorder (BD) has an estimated heritability of about 80%. Different pathways and candidate genes may contribute to the pathogenesis of BD, but definite mechanisms are yet unresolved. In a previous study, we identified the single nucleotide polymorphism (SNP) rs4500567, located in the upstream region of Tetraspanin 8 (TSPAN8), to be associated with bipolar disorder (BD).

View SamplesWe identified two isoforms of human MKL1 that differ in their N-terminal domains. Since MKL1 is a transcriptional coactivator of SRF and regulates many SRF target genes, we wanted to analyze if transcription is differentially regulated by the two isoforms upon stimulation of the Rho-actin-MKL1-SRF pathway.
TGF-β-induced differentiation into myofibroblasts involves specific regulation of two MKL1 isoforms.

View SamplesB cells provide humoral immunity by differentiating into antibody secreting plasma cells. Differentiation is dependent upon division and transcriptional changes, with commitment to B cell lineages associated with epigenetic changes. Analysis of early transcriptional and epigenetic events in B cell differentiation revealed that plasmablasts and plasma cells undergo dynamic changes in gene expression and a progressive DNA hypomethylation targeted to at least 10% of genes/loci. Of the differentially methylated loci, more than 99.7% were demethylated during differentiation and these clustered in cis-regulatory features such as enhancers and transcription factor binding sites. Changes in gene expression and DNA methylation coincided with each other at specific divisions during differentiation and inhibition of DNA methylation resulted in augmented plasma cell commitment in a division-dependent manner. These data identify a major epigenetic reprogramming event during early B cell differentiation coupled division and provide an approach to modulating humoral immune responses. Overall design: Splenic B cells (B220+ CD43-) from naïve C57/BL6J mice were labeled with CFSE or CTV and transferred into uMT mice and allowed to rest overnight prior to challenge with LPS. Three days post challenge adoptively transferred B cells representing distinct divisions were sorted out for molecular analysis. These divisions are labelled Div0, Div1, Div3, Div5, Div8- and Div8+. Division 8- refers to cells that divided at least 8 times but were CD138-, whereas Division 8+ refers to cells that divided at least 8 times but were CD138+. Cells were subjected to RNA-seq and Reduced Representation Bisulfite Sequencing.

View SamplesTo understand the role of Ezh2 in B cell differentiation B cells were stimulated ex vivo with LPS, Il2, and Il5 in the presence of DMSO or the selective Ezh2 inhibitor GSK343. Following 3 days culture, activated B cells and Plasmablasts were FACS isolated and RNA-seq was performed to identify the molecular effects of Ezh2 inhibition on B cell subsets during differentiation. Overall design: RNAseq on ex vivo differentiated B cell subsets treated with GSK343 or DMSO

View SamplesTo understand the role of LSD1 in B cell differentiation, mice with B cell conditional deletion of LSD1 were intravenously inoculated with LPS. After 3 days, B220+GL7-CD138- naïve B cells and CD138+ plasmablasts were FACS-sorted from the spleens and RNA-seq was performed to identify LSD1-target regulated genes. Overall design: RNA-seq on control or LSD1-deficient murine naïve B cells or plasmablasts.
