The experiment consists of 31 Systemic Lupus Erythematosus patient blood samples and 29 healthy donor blood samples. Overall design: Whole blood was collected in PaxGene tubes from 31 SLE and 29 healthy donors.

View SamplesThis experiment was designed to look for in vitro IL-3 gene signature in donor blood at two different time points (6 and 24 hours). RNA from lysed whole blood cells was used for the sequencing. Overall design: Lysed whole blood from seven healthy donors was stimulated with recombinant human IL-3 for 6 hours, or 24 hours, prior to RNA extraction for next-generation sequencing on the Illumina HiSeq platform. Unstimulated samples were included as controls.

View SamplesThe purpose of this experiment was to assess the genes upregulated when pDCs were stimulated with TLR7 agonist imiquimod and TLR9 agonist CpG C. Overall design: pDCs were isolated from six healthy donors by FACS sorting, and were stimulated with CpG and imiquimod for 18 hours, after which RNA was extracted for next generation sequencing on the Illumina HiSeq platform. Unstimulated samples were included as controls.

View SamplesRNAseq analysis of cloche m39 mutant zebrafish embryos and wild type siblings at 90% epiboly - tailbud stage Overall design: In order to isolate the cloche gene, RNAseq was performed on a deletion allele of the zebrafish cloche mutant. RNA was extracted from individual embryos at a stage the cloche gene was predicted to be expressed based on previous literature. RNA from the respective genoptypes was then pooled and subjected to RNAseq analysis.

View SamplesTo identify genes regulated by AP3/PI, we carried out microarray experiments using an Arabidopsis whole genome GeneChip array (ATH1 GeneChip, Affymetrix, Santa Clara, CA) in conjunction with an inducible AP3-GR system. For these experiments, we used 35S::AP3-GR transgenic plants in a 35S::PI, ap3-3 null mutant background for various dex or mock treatments. RNA was extracted from inflorescences at 0 and 4 hours after dex or a mock treatment and used as probes for our microarray experiments. Three biological replicates of each were hybridized to Affymetrix ATH1 arrays. We used the Affymetrix Microarray Suite software (MAS) to identify genes whose expression profiles changed only after dex-treatment and are likely targets of AP3/PI.

View SamplesGlucocorticoids (GCs) are steroid hormones widely used as pharmaceutical interventions, which act mainly by regulating gene expression levels. A large fraction of patients (~30%), especially those of African descent, show a weak response to treatment. To interrogate the contribution of variable transcriptional response to inter-ethnic differences, we measured in vitro lymphocyte GC sensitivity (LGS) and transcriptome-wide response to GCs in peripheral blood mononuclear cells (PBMCs) from African-American and European-American healthy donors. We found that transcriptional response after 8hrs treatment was significantly correlated with variation in LGS within and between populations. We found that NFKB1, a gene previously found to predict LGS within populations, was more strongly downregulated in European-Americans on average. NFKB1 could not completely explain population differences, however, and we found an additional 177 genes with population differences in the average log2 fold change (FDR<0.05), most of which also showed a weaker transcriptional response in AfricanAmericans. These results suggest that inter-ethnic differences in GC sensitivity reflect variation in transcriptional response at many genes, including regulators with large effects (e.g. NFKB1) and numerous other genes with smaller effects.
Inter-ethnic differences in lymphocyte sensitivity to glucocorticoids reflect variation in transcriptional response.

View SamplesThe aim of this experiment was to investigate differential gene expression in splenocytes stimulated with BCG from nave and BCG vaccinated mice. The differences between nave and BCG vaccinated mice might indicate the mechanisms by which BCG vaccination confers an enhanced ability of splenocytes from BCG vaccinated mice to inhibit growth of BCG in splenocyte cultures as compared with splenocytes from naive animals.
