Citizenship Education at the Republican Schools in France: Comprehensive Review and Teachers' Points of View
2019
Citizenship Education at the Republican Schools in France: Comprehensive Review and Teachers' Points of View This thesis deals with citizenship education in France, a subject that has been on the agenda for some thirty years and the object of intense debates, especially in a national community deeply shocked by recent terrorist attacks. As there are but few studies on the subject, especially from an empirical perspective (Bozec, 2016), our objective is a comprehensive review of citizenship education in France. We explore how the subject is conceived officially and integrates national curricula as well as how it is implemented at school. In fact, we seek to answer the question: how is citize…
Gene regulatory networks elucidating Huanglongbing disease mechanisms
2013
Next-generation sequencing was exploited to gain deeper insight into the response to infection by Candidatus liberibacter asiaticus (CaLas), especially the immune disregulation and metabolic dysfunction caused by source-sink disruption. Previous fruit transcriptome data were compared with additional RNA-Seq data in three tissues: immature fruit, and young and mature leaves. Four categories of orchard trees were studied: symptomatic, asymptomatic, apparently healthy, and healthy. Principal component analysis found distinct expression patterns between immature and mature fruits and leaf samples for all four categories of trees. A predicted protein - protein interaction network identified HLB-…
Transcriptome and metabolome analysis of citrus fruit to elucidate puffing disorder.
2014
a b s t r a c t A systems-level analysis reveals details of molecular mechanisms underlying puffing disorder in Citrus fruit. Flavedo, albedo and juice sac tissues of normal fruits and fruits displaying symptoms of puffing disorder were studied using metabolomics at three developmental stages. Microarrays were used to compare normal and puffed fruits for each of the three tissues. A protein-protein interaction network inferred from previous work on Arabidopsis identified hub proteins whose transcripts show significant changes in expression. Glycolysis, the backbone of primary metabolism, appeared to be severely affected by the disorder, based on both transcriptomic and metabolomic results. …
Transcriptome profiling of citrus fruit response to huanglongbing disease.
2010
Huanglongbing (HLB) or "citrus greening" is the most destructive citrus disease worldwide. In this work, we studied host responses of citrus to infection with Candidatus Liberibacter asiaticus (CaLas) using next-generation sequencing technologies. A deep mRNA profile was obtained from peel of healthy and HLB- affected fruit. It was followed by pathway and protein-protein network analysis and quantitative real time PCR analysis of highly regulated genes. We identified differentially regulated pathways and constructed networks that provide a deep insight into the metabolism of affected fruit. Data mining revealed that HLB enhanced transcription of genes involved in the light reactions of phot…
Saccharomyces cerevisiae signature genes for predicting nitrogen deficiency during alcoholic fermentation
2007
Genome-wide analysis of the wine yeast strain Saccharomyces cerevisiae PYCC4072 identified 36 genes highly expressed under conditions of low or absent nitrogen in comparison with a nitrogen-replete condition. Reverse transcription-PCR analysis for four of these transcripts with this strain and its validation with another wine yeast strain underlines the usefulness of these signature genes for predicting nitrogen deficiency and therefore the diagnosis of wine stuck/sluggish fermentations.
Positive selection in development and growth rate regulation genes involved in species divergence of the genus Radix
2015
AbstractBackgroundLife history traits like developmental time, age and size at maturity are directly related to fitness in all organisms and play a major role in adaptive evolution and speciation processes. Comparative genomic or transcriptomic approaches to identify positively selected genes involved in species divergence can help to generate hypotheses on the driving forces behind speciation. Here we use a bottom-up approach to investigate this hypothesis by comparative analysis of orthologous transcripts of four closely related EuropeanRadixspecies.ResultsSnails of the genusRadixoccupy species specific distribution ranges with distinct climatic niches, indicating a potential for natural …
Inhibition of activated STAT5 in Bcr/Abl expressing leukemia cells with new pimozide derivatives.
2014
STATs are transcription factors acting as intracellular signaling after stimulation with cytokines, growth factors and hormones. STAT5 is also constitutively active in many forms of cancers, including chronic myelogenous leukemia, acute lymphoblastic leukemia and Hodgkin's lymphoma. Recently, literature reported that the neuroleptic drug pimozide inhibits STAT5 phosphorylation inducing apoptosis in CML cells. We undertook an investigation from pimozide structure, obtaining simple derivatives with cytotoxic and STAT5-inhibitory activity, two of them markedly more potent than pimozide.

NFAT transcription factors in control of peripheral T cell tolerance.
2006
The Ca++-regulated calcineurin/NFAT cascade is one of the crucial signalling pathways that controls adaptive immunity. However, a number of novel experimental data suggest that, in addition to their role in T cell activation, NFATc transcription factors play also a decisive role in the generation of peripheral tolerance against self-antigens. This function of NFATc factors is mediated by controlling activation-induced cell death and clonal anergy of T helper cells and the activity of regulatory T cells. The multi-functional role of NFATc proteins characterize these transcription factors as key regulators of immunological tolerance and, if dysregulated, of development of autoimmune diseases.
cDNA Synthesis and Cloning
1998
The isolation of intact messenger RNA and its conversion into cDNA copies by avian or Moloney murine reverse transcriptase, as well as subsequent amplification of gene transcripts by the PCR technique, are becoming increasingly important tools in molecular biology. At present, these techniques have been often necessary and widely used for the analysis of individual mRNA levels in cells and tissues by Northern blot analysis, nuclease protection analysis and in situ hybridization. Another important application of RNA templates is the construction of representative cDNA libraries in order to clone genes, to investigate their molecular structure and to express them in prokaryotic and/or eukary…
