Affymetrix Rat Expression 230A Array (rae230a)
Description
The transcriptional effects of urocortin I, urocortin II and tempol were compared to saline treatment in a rat model of in vivo coronary artery occlusion model of ischaemia/reperfusion injury of 25 min ischaemia and 2 hr reperfusion. <br></br>The treatment groups were as follows (i) sham operation or LAD occlusion with infusion of (ii) saline, (iii) 15 ?g/kg Ucn I, (iv) 15 ?g/kg Ucn II and (v) 100 mg/kg tempo infused just prior to reperfusionl.<br></br>Following 2 hr reperfusion the left ventricle was removed, snap frozen, followed by RNA extraction.

Description
Dorsomorphin is a small molecule inhibitor of type I bone morphogenic protein receptors (BMPRs). We have found that dorsomorphin affects a wide range of T cell function. In order to obtain the bigger picture of the effects of DM in T cell activation. transcriptomic analysis was performed using mouse primary CD25-CD4+ T cells with either DM (4 M) or vehicle in the presence or absence of stimulation by anti-CD3 and -CD28 antibodies.

Description
To clarify how Foxp3 regulates its target genes, we performed co-immunoprecipitation experiments and found that Foxp3 physically bound to AML1/Runx1 (Ono, M. et al, Nature, 2007). In this series of study, we compared gene regulations by AML1, wild type Foxp3, and a Foxp3 mutant with defective binding to AML1.
Publication Title
Foxp3 controls regulatory T-cell function by interacting with AML1/Runx1.

Description
T-cell replete cord blood transplantation results in a rapid thymus-independent T-cell reconstitution which is strikingly CD4+ biased compared to the well-established observation of CD8+ T-cell biased expansion after T-cell replete bone marrow transplant.

Description
Gene expression on peripheral blood mononuclear cells (PBMC) from SPARKS CHARMS juvenile idiopathic arthritis (JIA) cohort pre and post methotrexate therapy. This is the first study to our knowledge, to evaluate gene expression profiles in children with JIA before and after MTX, and to analyze genetic variation in differentially expressed genes. We have identified a gene, which may contribute to genetic variability in MTX response in JIA.

Description
Children with oligoarticular JIA (arthritis in 4 or fewer joints) can either continue to have this mild form of arthritis (persistent oligoarticular JIA) or extend to a more sever form involving more than 4 joints (extended oligoarticular JIA)
Publication Title
Biologic predictors of extension of oligoarticular juvenile idiopathic arthritis as determined from synovial fluid cellular composition and gene expression.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
SF-1 (NR5A1) was overexpressed (Over) or knocked down with shRNA (shRNA) in NCI-H295R human adrenocortical tumor cells and differential global gene expression analysed 48 hours later using Affymetrix GeneChip Human Gene 1.0ST arrays. Over: 5 million cells were transfected (Amaxa Nucleofection) with 10 ug of a pIRES2-AcGPF1-Nuc construct co-expressing SF-1 cDNA and GFP. For experimental control, a mutagenized pIRES2 construct, bearing the G35E mutation in SF-1 that impairs its transactivation function in vivo and in vitro was used. shRNA: 5 million cells were transfected (Amaxa Nucleofection) with 10 ug of the SureSilencing shRNA Plasmid for Human NR5A1 with GFP marker kit (SABioscience). For experimental control, mismatch constructs provided in the kit were used. In both experiments (Over and shRNA), cells were harvested, prepared, and submitted to fluorescence-activated cell sorting (FACS) in a MoFlo XDP sorter 48 hours after transfection. Viable GFP-expressing cells were pooled and resuspended in TRIzol reagent for RNA extraction. Total RNA was extracted, and RNA quality control performed using a 2100 Bioanalyzer.

Description
We hypothesised that neutrophil pathways could be also be important in the pathogenesis of sJIA. We therefore studied the gene profile in both PBMC and neutrophils of sJIA patients treated with tocilizumab.

Description
Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations.
Publication Title
Interactions between innate antiviral and atopic immunoinflammatory pathways precipitate and sustain asthma exacerbations in children.
