Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Inflammatory mechanisms have been suggested to play a role in the development of heart failure (HF), but a role for chemokines is largely unknown. The aim of this study was to analyze the role of the chemokine CXCL13 and its receptor CXCR5 in cardiac pathophysiology leading to HF
Publication Title
Lack of chemokine signaling through CXCR5 causes increased mortality, ventricular dilatation and deranged matrix during cardiac pressure overload.

Description
We used high throughput sequencing to analyze the transcriptional profiling of EVT. By comparing the transcriptional profiling of EVT with or without H19 knockdown, numerous genes showed significantly altered expression as a result of H19 repression. Overall design: HTR cells were transfected with either control siRNA or siH19. 48h later after transfection, total RNA was extracted for library preparation and RNA-seq analysis to compare trancript profiles between siCon and siH19 cells.

Description
Patients with systemic lupus erythematosus (SLE) have a markedly increased risk to develop cardiovascular disease, and traditional cardiovascular risk factors fail to account for this increased risk. We used microarray to probe the platelet transcriptome in individuals with SLE and healthy controls, and the gene and protein expression of a subset of differentially expressed genes was further investigated and correlated to platelet activation status. Real-time PCR was used to confirm a type I interferon (IFN) gene signature in patients with SLE, and the IFN-regulated proteins PRKRA, IFITM1 and CD69 (p<0.0001) were found to be up-regulated in platelets from SLE patients as compared to healthy volunteers. Notably, patients with a history of vascular disease had increased expression of type I IFN-regulated proteins as well as more activated platelets as compared with patients without vascular disease. We suggest that interferogenic immune complexes stimulate production of IFN which up-regulates the megakaryocytic type I IFN-regulated genes and proteins. This could affect platelet activation and contribute to development of vascular disease in SLE. In addition, platelets with type I IFN signature could be a novel marker for vascular disease in SLE.

Description
Myocardial infarction (MI) triggers a reparative response involving fibroblast proliferation and differentiation driving extracellular matrix modulation necessary to form a stabilizing scar. Recently, it was shown that a genetic variant of the base excision repair enzyme endonuclease VIII-like 3 (NEIL3) was associated with increased risk of MI in humans. Here, we report elevated myocardial NEIL3 expression in heart failure patients and marked myocardial upregulation of Neil3 following MI in mice, especially in a fibroblast-enriched cell fraction. Neil3-/- mice showed increased mortality after MI compared to WT, caused by myocardial rupture. Neil3-/- hearts displayed enrichment of mutations in genes involved in mitogenesis of fibroblasts and transcriptome analysis revealed dysregulated fibrosis. Correspondingly, proliferation of vimentin+ and aSMA+ (myo)fibroblasts was increased in Neil3-/- hearts following MI. We propose that NEIL3 operates in genomic regions crucial for regulation of cardiac fibroblast proliferation and thereby controls extracellular matrix modulation after MI. Overall design: RNA from infarcted and non-infarcted LV of WT and Neil3-/- C57BL/6 mice obtained three days after induced myocardial infarction were subjected to RNA sequencing using Illumina Hiseq 2000

Description
We analyzed the global gene expression pattern of Tregs between healthy donors and prostate cancer patients. We found that genes related to cell cycle, cellular proliferation, immune responses, hematological system development and function were differentially expressed in Tregs from prostate cancer patients.

- Affymetrix Maize Genome Array (maize)
Description
Maize transgenic event MON810, grown and commercialised worldwide, is the only cultivated GM event in EU. Maize MON810, variety DKC6575, and the corresponding near-isogenic Tietar were studied in different growing conditions, to assess their behaviour in response to drought. Profiling gene expression in water deficit regimes and in generalised water stress showed an up-regulation of different stress- responsive genes. A greater number of differentially expressed genes was observed in Tietar rather than in DKC6575, with genes belonging to transcription factor families and genes encoding HSPs, LEAs and detoxification enzymes. Since these genes have been from literature, indicated as typical of stress responses, their activation in Tietar rather than in DKC6575 may be reminiscent of a more efficient water stress response. DKC6575 was also analysed for the expression of the transgene CryIAb (encoding for the delta-endotoxin insecticidal protein) in water limiting conditions. In all the experiments the CryIAb transcript was not influenced by water stress, but expressed at a constant level. This suggests that though a different pattern of sensitivity to stress, the transgenic variety maintains the same expression level for the transgene.

Description
The overall aim of the present work was to identify MTG16 functions in leukemia cells. Alterations in quantity of the MTG16 co-repressor might affect gene regulation and cell metabolism in malignant cells. Differentiated cells secure energy for cellular homeostasis largely by mitochondrial oxidation. Whereas, mature cells, proliferating tumour cells including leukemia cells depend on glycolysis and mitochondrial respiration may be low even in oxygenrich environments.The same signal transduction pathways that govern cell proliferation give instructions for nutrient uptake and co-regulate metabolic processes. In this manner, the metabolism of tumor cells, and other highly proliferating cells, is adapted to stimulate anabolic glycolysisdriven processes for incorporation of nutrients into nucleotides, amino acids and lipids to synthesize macromolecules required for growth and proliferation.
