Description
As4.1 cells are a renin-expressing cell line commonly used to study the molecular regulation of the mouse renin gene. In the present study, the global gene expression profile was assessed in these cells under control conditions (VEHICLE) and after treatment with interleukin (IL) or hydrogen peroxide (HP), both of which negatively regulate mouse renin gene expression.

Description
Ligand-mediated activation of the nuclear hormone receptor PPAR gamma lowers blood pressure and improves glucose tolerance in humans. Two naturally occurring mutations (P467L, V290M) in the ligand binding domain of PPAR gamma have been described in humans that lead to severe insulin resistance and hypertension. Experimental evidence suggests that these mutant versions of PPAR gamma act in a dominant negative fashion. To better understand the molecular mechanisms underlying PPAR gamma action in the vasculature, we determined the gene expression patterns in mouse aorta in response to activation or interference with the PPAR gamma signaling pathway.

Description
Single O-GlcNAc modification orchestrate by O-GlcNAc Transferase (OGT) and O-GlcNAcase (OGA alias MGEA5) enzymes, affects signal transduction and gene expression by chromatin modulation. We developed Oga deleted MEF (mouse embryonic fibroblast) cells to investigate effects of O-GlcNAc modification in mice. RNA isolated from Mouse Embryonic Fibroblast cells generated from Oga Knock out (KO) Heterozygous (Het) and wild type (WT) cells and subjected to microarray analysis.

Description
The generation of specific types of neurons from stem cells offers important opportunities in regenerative medicine. However, future applications and proper verification of cell identities will require stringent ways to generate homogenous neuronal cultures. Here we show that under permissive culturing conditions individual transcription factors can induce a desired neuronal lineage from virtually all expressing cells by a mechanism resembling developmental binary cell fate switching. Such efficient selection of cell fate resulted in remarkable cellular enrichment that enabled global gene expression validation of generated neurons and identification of novel features in the studied cell lineages. Several sources of stem cells have a limited competence to differentiate into e.g. dopamine neurons. However, we show that the combination of factors that normally promote either regional or dedicated neuronal specification can overcome limitations in cellular competence and promote efficient reprogramming also in more remote neural contexts, including human neural progenitor cells.
