Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Strategies to enhance islet b-cell survival and regeneration while refraining inflammation through manipulation of molecular targets would provide means to stably replenish the deteriorating functional b-cell mass detected in both Type 1 and Type 2 Diabetes Mellitus (T1DM and T2DM). Herein we report that over expression of the islet enriched transcription factor Pax4 refrains development of hyperglycemia in the RIP-B7.1 mouse model of T1DM through reduced insulitis, decreased b-cell apoptosis correlating with diminished DNA damage and increased proliferation. Transcriptomics revealed up regulation of genes involved in immunomodulation, cell cycle and ER homeostasis in islets over expressing Pax4 as compared to the T2DM-linked mutant variant Pax4R129W. Pax4 but not Pax4R129W protected islets from thapsigargin-mediated ER-stress apoptosis. Collectively, Pax4 is a critical signaling hub coordinating regulation of distinct molecular pathways resulting in improved b-cell fitness whereas Pax4R129W sensitizes to death under stress. More importantly we highlight potential common pharmacological targets for the treatment of DM.

Description
Seed germination is a critical developmental process in plant propagation. Knowledge of the gene expression patterns in this critical process is important in order to understand the main biochemical reactions involved in successful germination, specially for economically relevant plants such as Maize.

Description
Periostin participates in different processes involved in connective tissue homeostasis. It is also involved in repairment of damaged tissues. We used the osteoblast murine cell line MC3T3-E1 cell line to show how overexpresion of periostin is able to increase their adhesion properties while diminishing their migration capacity. By differential gene expression we evaluated putative targets involved in those cellular properties.

Description
Heart failure (HF) is a major health and economic burden in developed countries. It has been proposed that the pathogenesis of HF may involve the action of mitochondria. Here we evaluate three different models of HF: tachycardiomyopathy, HF with preserved left ventricular (LV) ejection fraction, and LV myocardial ischemia and hypertrophy. Regardless of whether LVEF is preserved or reduced, our results indicate that the three models share common molecular features: an increase in mitochondrial ROS, followed by ultrastructural alterations in the mitochondrial cristae and loss of mitochondrial integrity that lead to cardiomyocyte death. We show that the ablation of the mitochondrial protease OMA1 averts cardiomyocyte death in all three experimental HF models, and thus, plays a direct role in cardiomyocyte protection. This finding identifies OMA1 as a potential target for preventing the progression of myocardial damage in HF associated to a variety of etiologies. Overall design: Transcriptome analysis of 12-week-old wild type mice versus OMA1 KO mice under control (non-treated) or treated with Isoproterenol chronically (implanted minipumps) for 7 days in heart tissue. The nuclear genetic background for both genotypes is C57BL/6JOlaHsd.

Description
Cardiomyopathies-associated metabolic pathologies (e.g. T2D and insulin resistance) are a leading cause of mortality. It is known that the association between the pathologies works in both directions, where heart failure can lead to metabolic derangements such as insulin resistance. This intricate crosstalk exemplifies the importance of a fine coordination between one of the most energy demanding organs and an equilibrated carbohydrate metabolism. In this light, to assist in the understanding of the role of insulin regulated glucose transporters and the development of cardiomyopathies, we set out to study GLUT12. GLUT12 is a novel insulin regulated GLUT expressed in the main insulin sensitive tissues such as cardiac and skeletal muscle and adipose tissue. This study investigates the role of GLUT12 in heart failure and diabetes by developing a model for glut12 deficiency in zebrafish. Overall design: 6 samples in total were analyzed. 3 replicates from control samples (injected with contol MO) and 3 replicates from glut12 morphant samples (injected with glut12 splice MO). In each sample 10 embryos were pooled.
