Splenocytes from lymphoreplete, unmanipulated mice were analyzed for basal mRNA levels. We hypothesized, based on previous data from our lab and others, that many cytokine/inflammatory response genes would show an increase from na誰ve CD5lo<CD5hi<Virtual memory. Overall design: mRNA was analyzed from mouse splenocytes separated into na誰ve CD5lo, na誰ve CD5hi, and virtual memory cells. Mice were lymphoreplete and unmanipulated.
Virtual memory T cells develop and mediate bystander protective immunity in an IL-15-dependent manner.

View SamplesGene expression analysis was performed on 30 Neuroblastomas to identify genes whose transcription is significantly altered by recurrent chromosomal alterations. Genomic copy number losses and gains had been delineated in the tumours using FISH and SNP arrays. We have identified genes significantly altered by 7 recurrent alterations: 1p, 3p, 4p, 10q and 11q loss, 2p and 17q gain, and genes co-amplified and over-expressed as a result of MYCN amplification.

View SamplesGlial progenitor cells (GPCs) of the adult human white matter, which express gangliosides recognized by monoclonal antibody A2B5, are a potential source of glial tumors of the brain. We used A2B5-based sorting to extract progenitor-like cells from a range of human glial tumors, that included low-grade glioma, oligodendroglioma, oligo-astrocytomas, anaplastic astrocytoma, and glioblastoma multiforme. The A2B5+ tumor cells proved tumorigenic upon orthotopic xenograft, and the tumors generated reflected the phenotypes of those from which they derived.
Transcriptional differences between normal and glioma-derived glial progenitor cells identify a core set of dysregulated genes.

View Samplesdrl expression initiates during gastrulation and condenses as a band of cells at the prospective lateral embryo margin. In late epiboly, drl:EGFP is detectable as a band of scattered EGFP-fluorescent cells; after gastrulation, drl:EGFP-positive cells coalesce at the embryo margin that then in somitogenesis break down into the anterior and posterior lateral plate with subsequent cell migrations that form the posterior vascular/hematopoietic stripes and the anterior cardiovascular and myeloid precursors.

View SamplesIllumina HiSeq2000 technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after 3 months of contact in order to identify mycorrhiza-regulated transcripts. 100bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) reference genome. Overall design: mRNA profiles from Populus trichocarpa roots colonized by Laccaria bicolor for three months as well as from control roots were generated by using one lane of 1X100bp Illumina HiSeq2000 sequencing per sample.
Populus trichocarpa encodes small, effector-like secreted proteins that are highly induced during mutualistic symbiosis.

View SamplesPolyinosinic:polycytidylic acid (poly I:C) is a synthetic analogue of double-stranded (ds)RNA, a molecular pattern associated with viral infections, that is used to exacerbate inflammation in lung injury models. Despite its frequent use, there are no detailed studies of the responses elicited by a single topical administration of poly I:C to the lungs of mice. Our data provides the first demonstration that the molecular responses in the airways induced by poly I:C correlate to those observed in the lungs of COPD patients. These expression data also revealed three distinct phases of response to poly I:C, consistent with the changing inflammatory cell infiltrate in the airways. Poly I:C induced increased numbers of neutrophils and NK cells in the airways, which were blocked by CXCR2 and CCR5 antagonists, respectively. Using gene set variation analysis on representative data sets, gene sets defined by poly I:C-induced DEGs were enriched in the molecular profiles of chronic obstructive pulmonary disease (COPD), but not idiopathic pulmonary fibrosis patients. Collectively, these data represent a new approach for validating the clinical relevance of preclinical animal models and demonstrate that a dual CXCR2/CCR5 antagonist may be an effective treatment for COPD patients.
Double-stranded RNA induces molecular and inflammatory signatures that are directly relevant to COPD.
