We used microarrays to detail the global programme of gene expression upon the over-expression of seven different differentiation-associated, E1A-regulated microRNAs.
Differentiation-associated microRNAs antagonize the Rb-E2F pathway to restrict proliferation.

View SamplesThis experiment was carried out in the context of a pharmacogenetic study of long-term (4-year follow-up) response to Interferon-beta treatment in two cohorts of Italian Multiple Sclerosis patients, to identify genetic variants (SNPs) that may influence response to IFN-beta. We integrated results from meta-analysis of the two cohorts with gene expression profiling of IFN stimulated PBMCs from 20 healthy controls and eQTL analyses, to look at possible enrichment of IFN-beta induced genes with genes mapped by top-ranking meta-analyzed SNPs.

View SamplesWe exploited microarrays to detail the global program of gene expression underlying normal stem cells and cancer stem cells in the cerebellum and in medulloblastomas (MBs).

View SamplesWe have generated mouse models of real CMT1B mutations in the gene encoding for myelin protein zero (P0). One of these mutants, P0S63del is retained in the ER where it elicits an unfolded protein response (UPR). Genetic ablation of the UPR factor CHOP restores the motor capacity in S63del mice. We used microarray to decipher the molecular mechanism undelying the P0S63del neuropathy and the rescue in S63del/Chop null nerves.

View SamplesCD1d expression by thymocytes is required to select iNKT cells. When CD1d is expressed only on thymocytes (pLck-CD1d tg mice), iNKT cells are hyperresponsive to antigen stimulation suggesting that, in physiological conditions, these cells undergo functional education mediated by additional CD1d-expressing cells. Here, we investigated the mechanisms of this functional education. We find that peripheral iNKT cells from pLck-CD1d tg mice express significantly less SHP-1, a tyrosine phosphatase negatively regulating TCR signaling, than WT cells. iNKT cells from heterozygous SHP-1-mutated motheaten mice, displaying similar SHP-1 reduction as pLck-CD1d tg iNKT cells, are antigen-hyperresponsive. Restoring normal CD1d expression in pLck-CD1d tg mice normalizes SHP-1 expression and responsiveness of iNKT cells. In WT mice, iNKT cells upregulate SHP-1 and decrease responsiveness upon emigration from thymus to periphery. This depends on contacts with CD1d-expressing DCs. iNKT cell functional education is therefore controlled by DCs via tuning SHP-1 expression level in the periphery.

View SamplesGene expression profiling following different learning paradigms may help in defining the moleular pathways of memory formation. In this study we analyzed the gene expression pattern of murine hippocampus at different time points (0.5 h, 2h, 6h) after trace fear conditioning. We compared trained mice with naive mice that remained in their homecages.
