The aim of this work was to identify functional features that are specific of human Treg cells, through the identification of genes that are differentially expressed: 1/ in activated Treg clones versus activated Thelper clones; 2/ in Th clones activated in the presence versus the absence of TGFb; 3/ in suppressed Th clones, i.e. Th clones activated in the presence of Treg clones, versus controls.
Comparison of stable human Treg and Th clones by transcriptional profiling.

View SamplesAberrant signal transduction contributes substantially to leukemogenesis. The Janus kinase 1 (JAK1) gene encodes a cytoplasmic tyrosine kinase that noncovalently associates with a variety of cytokine receptors and plays a nonredundant role in lymphoid cell precursor proliferation, survival, and differentiation. Somatic mutations in JAK1 occur in individuals with acute lymphoblastic leukemia (ALL). JAK1 mutations were more prevalent among adult subjects with the T cell precursor ALL, where they accounted for 18% of cases, and were associated with advanced age at diagnosis, poor response to therapy, and overall prognosis
ALL-associated JAK1 mutations confer hypersensitivity to the antiproliferative effect of type I interferon.

View SamplesDiffuse large B-cell lymphoma (DLBCL) has striking clinical and molecular variability. Although a more precise identification of the multiple determinants of this variability is still under investigation, there is a consensus that high-clinical-risk DLBCL cases require a risk-adapted therapy, since intensification of chemotherapy with autologous stem-cell transplantation (ASCT) has been shown to improve the prognosis for high-risk patients in randomised clinical trials.

View SamplesPrimary cells deficient for PDCD10/CCM3 do not enter senescence as control cells. Microarray analysis was performed in cells transduced with non-targeting shRNA and CCM3 shRNA at passage 7 (early passage) and passage 11 (late passage), when control cells are already senescent.

View SamplesThe recent interest in the role of bone marrow derived endothelial progenitor cells in the benefits of estrogen on cardiovascular health brought us to evaluate if estrogen could affect cardiac repair more broadly by regulating biological processes involved in the functional organization of the bone marrow stem cell niche.

View SamplesSubstantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. However, ventral tegmental area (VTA), a region adjacent to SNpc, is less affected in PD. Until now, molecular mechanisms behind VTA aging have not been fully investigated using high throughput techniques.

View SamplesGrowth of the drosophila eye imaginal discs is controlled by the activation of Notch in the dorsal-ventral boundary. Overexpression in the eye disc of the Notch ligand Delta together with lola and pipsqueak from the GS(2)88A8 line induces tumoral growth. We used microarray to analyze the expression profile of tumoral discs.
Imaginal discs secrete insulin-like peptide 8 to mediate plasticity of growth and maturation.
