Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In order to identify the genes regulated in mouse embryonic stem cells (mESC) by the effect of low concentrations of nitric oxide (NO), we analysed the transcriptome of cells treated with NO and compared it to those of cells cultured in the absence of leukemia inhibitory factor (LIF), and in the presence of LIF. We used the cell line D3-pOct4, which carries the enhanced Green Fluorescence Protein gene (eGFP) under the control of the Oct-4 promotor. This line is continuously maintained in the undifferentiated state in the presence of LIF, in comparison with the wild type line .

Description
Identification of genes regulated in human embryonic stem cells by the effect of low concentrations of nitric oxide. The transcriptome of cells treated with NO were compared with that of cells cultured in abscense of LIF, and undifferentiated ES cells cultured in presence of LIF. The H181 hES cell line was used for the experiments. These data complement a previous study realized in mES cells under the same NO conditions . The aim of the work is to know how NO modify transcriptome of ES cells and how participate in the modulation of self renewal and differentiation.

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
Homologue of Enhancer-of-split 1 (Hes1) is a transcription factor that regulates neuronal plasticity, promoting the growth of dendrites and increasing the GABAergic input. A higher expression of Hes1 also results in neuronal resistance against the noxious activity of amyloid beta, the main agent in the advent and progression of the Alzheimer's disease. As a transcription factor, Hes1 controls de expression of many genes. Using the microarray technology we have detected that the expression of one secreted synaptic protein, cerebellin 4 (Cbln4) was particularly increased upon overexpression of Hes1. We also present evidence that Cbln4 plays an essential role in the formation and maintenance of inhibitory GABAergic connections and that either overexpression of Cbln4 in cultured hippocampal neurons or the application of recombinant Cbln4 to the cultures increased the number of GABAergic varicosities and rescued neurons from amyloid beta induced cell death.
