Expression quantitative trait loci (eQTL) analyses were conducted separately on the glomerular and tubular portions of healthy human kidney samples obtained from subjects of European descent. Overall design: We aimed to define genotype driven gene expression changes in the glomerular and tubular compartments of human kidneys, identifying genetic variants (eVariants) that influence the expression of genes (eGenes). Later, we integrated this information with genotype and phenotype association studies (GWAS) to identify genes for which expression in the kidney shows differences in patients with GWAS variants.

View SamplesMyelopoiesis is impaired in Raptor-deleted mice (CreER-Rptor-flox/flox). To evaluate the transcriptional changes in myeloid precursors , we isolated CMP (LinSca-1c-Kit+CD34+FcRII/IIImid), GMP (LinSca-1c-Kit+CD34+FcRII/IIIhigh) and Lin (B220, Ly6C, Ly6G, CD3, Ter-119) negative cells (Lin) from bone marrow of WT or CreER-Rptor-flox/flox mice. RNA was isolated from CMP and GMP immediately after sorting and Lin- cells were cultured for 12 hours with M-CSF (10 ng/mL) in 10% FBS and 1% P/S DMEM before RNA isolation.

View SamplesCD8+ DCs play key role in CD8+ T cell priming, however, the underlying signaling mechansim is unclear. We used a data-driven network-based systems biology approach and identified Hippo signaling kinases as key selective modualtors in CD8+ DCs. We focused on Mst1/Stk4 to further investigate the novel function of Hippo signaling in CD8+ DCs. All transcriptional profies were evalated by microarray.

View SamplesThis experiment aims to identify the biological pathways and diseases associated with the cytokine Interleukin 13 (IL-13) using gene expression measured in peripheral blood mononuclear cells (PBMCs). Overall design: The experiment comprised of samples obtained from 3 healthy donors. The expression profiles of in vitro IL-13 stimulation were generated using RNA-seq technology for 3 PBMC samples at 24 hours. The transcriptional profiles of PBMCs without IL-13 stimulation were also generated to be used as controls. An IL-13R-alpha antagonist (Redpath et al. Biochemical Journal, 2013) was introduced into IL-13 stimulated PBMCs and the gene expression levels after 24h were profiled to examine the neutralization of IL-13 signaling by the antagonist.
Combining multiple tools outperforms individual methods in gene set enrichment analyses.

View SamplesG-CSF is a hemopoietic growth factor that has a role in steady state granulopoiesis, as well as in mature neutrophil activation and function. We developed a neutralizing monoclonal antibody to the murine G-CSF receptor (G-CSFR), which antagonizes binding of murine G-CSF and inhibits G-CSFR signalling. Anti-G-CSFR rapidly halts the progression of established disease in collagen antibody-induced arthritis (CAbIA). Neutrophil accumulation in joints is inhibited, without rendering animals neutropenic, suggesting an effect on homing to inflammatory sites. Neutrophils in the blood and arthritic joints of anti-G-CSFR treated mice show alterations in cell adhesion receptors, while anti-G-CSFR suppresses local production of proinflammatory cytokines and chemokines known to drive tissue damage. Our aim in this study was to use differential gene expression analysis of joint and blood neutrophils to more thoroughly understand the effect of G-CSFR blockade on the inflammatory response following anti-G-CSFR therapy in CAbIA.

View SamplesC. elegans GLD-2 forms an active PAP with multiple RNA-binding partners to regulate diverse aspects of germline and early embryonic development. One GLD-2 partner, RNP-8, was previously shown to influence oocyte fate specification. To identify transcripts selectively associated with both GLD-2 and RNP-8, we employ a genomic approach using the method of RNA immunoprecipitation followed by microarray analysis (RIP-chip).

View SamplesDifferent wheat cultivars may be classified as either winter or spring varieties depending on whether they require exposure to an extended period of cold in order to become competent to flower. Using a growth regime that mimics the conditions that occur during a typical winter in Britain, we wished to survey the genes that are involved in phase transition as well as those involved in cold-acclimation.
