- Illumina MouseWG-6 v2.0 expression beadchip
Description
The aim of this study is to address the functional role of miRNAs in the FoxD1+ renal stroma progenitors and derivatives during embryonic kidney development. To achieve this, we generated transgenic mice that lack miRNAs in the renal stroma lineage (FoxD1 Cre;Dicer), and performed a microarray analysis on E15.5 whole kidneys to determine the transcriptional changes.

Description
Background: Even though much progress has been made in the understanding of the molecular nature of glioma, the survival rates of patients affected of this tumour have not changed significantly during these years. Thus, a deeper understanding of this malignancy is still needed in order to predict its outcome and improve patient treatment. Here, we report that VAV1, a GDP/GTP exchange factor for Rho/Rac proteins with oncogenic potential that is involved in the regulation of cytoskeletal dynamics and cell migration.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Progressive myoclonus epilepsy of Unverricht-Lundborg type (EPM1) is an inherited neurodegenerative disease with myoclonus, seizures and ataxia, caused by the mutations in cystatin B (CSTB) gene. In an approach towards understanding the molecular basis of pathogenic events in EPM1 we have utilized the cystatin B deficient mice (Cstb-/-), a model for the disease. We have characterized the gene expression changes from the cerebellum of Cstb-/- mouse at postnatal day 7 (P7) and P30 as well as in cultured cerebellar granule cells using a pathway-based approach. A marked upregulation of immune response genes was seen at P30, reflecting the ongoing neuropathology, however, the observed alterations in complement cascade genes could also imply defects in synaptic plasticity. Differentially expressed genes in pre-symptomatic Cstb-/- animals at P7 were connected to synaptic function and plasticity and in cultured cerebellar granule cells to cellular biogenesis, cytoskeleton and intracellular transport. Especially GABAergic pathways were affected.
Publication Title
Gene expression alterations in the cerebellum and granule neurons of Cstb(-/-) mouse are associated with early synaptic changes and inflammation.

Description
Background and aims: Dysregulation of intestinal epithelial cells performance associates with an array of pathologies whose onset mechanisms are incompletely understood. The aim of the present study was to provide a map of gene expresssion patterns along the human healthy adult gastro-intestinal tract and to implement a new procedure for microarray data noise filtering that would allow their use as a reference when screening for pathological deviations, such as inflammatory bowel disease (IBD). Methods: Gene expression profiles in antrum, duodenum, jejunum, ileum and transverse colon biopsies were measured with the Affymetrix U133A array and principal component analysis was used to identify region-selective biomarkers. These data were intersected with highly variable genes from a public dataset of gene expression in the ileal and colonic healthy regions of UC and Crohns disease patients. Moreover, gene sets covering gut functions not entirely accounted for by the available public tools were constructed to monitor their expression along the GI tract. Results: 166 genes were found to be responsible for distinguishing the five regions considered. Fourteen had never been described in the GI tract, including a semaphorin probably implicated in pathogen invasion, and six other novel genes. Similar analysis of the IBD datasets revealed that samples stratify based on disease rather than on the intestinal region. This withstanding, eleven genes were identified as possible early predictors of Crohns and/or UC in ileum and/or colon. These include CLCA4 and SLC26A2, both implicated in ion transport. Conclusions: This novel approach, validated by retrieving known gene profiles, allowed the identification of promising new leads both in health and IBD state.

Description
Winged bean (WB), Psophocarpus tetragonolobus, is a tropical legume, the potential of which is not yet been understood. We found that a 5 week-oral administration of WB seed extract inhibited wrinkle formation induced by repeated tape stripping (TS), which is a model of lichenification in human chronic eczematous dermatitis.
