Description
Lineage commitment during Embryonic Stem Cells (ESCs) differentiation is controlled not only by a gamut of transcription factors but also by epigenetic events, mainly histone deacetylation and promoter DNA methylation. Moreover, the DNA demethylation agent 5-Aza-2-deoxycytidine (AzadC) has been widely described in the literature as an effective chemical stimulus used to promote cardiomyogenic differentiation in various stem cell types; however, its toxicity and instability complicate its use. Thus, the purpose of this study was to examine the effects of zebularine, a stable and non-toxic DNA cytosine methylation inhibitor, on ESCs differentiation. Herein are the Affymetrix Expression data obtained from RNA of murine ESCs treated with zebularine.

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
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.
