We provide here the alterations in gene expression profiles of HepaRG cells, a validated model for cellular steatosis, exposed to three concentration of the polychlorinated biphenyl (PCB) 126, one of the most potent chemical inducing NAFLD. Additionnally, three concentration of the pesticide active ingredient glyphosate were tested. This ultimately suggested sensitive biomarkers of exposure. A gene ontology analysis showed hallmarks of an activation of the AhR receptor by dioxin-like compounds. Our study provides grounds for the development of molecular signatures of fatty liver diseases to rapidly assess toxic effects of chemicals in the HepaRG cell line. Overall design: Differentiated HepaRGTM cells (HPR 116) were purchased from Biopredic International. The cells were kept in the general purpose medium until day 8, when the culture becomes well organized and includes well-delineated trabeculae and many canaliculi-like structures. Three concentrations of the PCB were then tested from day 8 to day 14, in order to cover a wide range of biological effects, starting from low environmental exposures (100 pM) to high concentrations of (1 uM), with an intermediate concentration (10 nM). Three concentrations of glyphosate, or one concentration of the Roundup herbicide (Grand Travaux +) were also tested in the same system.

The cells were kept in the general purpose medium until day 8, when the culture becomes well organized and includes well-delineated trabeculae and many canaliculi-like structures. Three concentrations of the different pesticide active ingredients (quizalofop-p-ethyl, isoxaflutole and mesotrione ) were then tested from day 8 to day 14. In order to ensure coverage of a wide range of potential biological effects, three concentrations of each active principle were tested; a concentration representative of low environmental exposure (0.1 uM), an intermediate concentration (10 uM) and a high concentration (1000 uM).

View SamplesWe provide here the alterations in gene expression profiles of 3T3-L1 cells, a validated model for adipogenesis, exposed to quizalofop-p-ethyl for 6h, 24h and 12 days. Overall design: Exposure to endocrine disrupting chemicals is a risk factor for obesity. The most commonly used pesticide active ingredients have never been tested in an adipogenesis assay. We tested for the first time the lipid accumulation induced by glyphosate, 2,4-dichlorophenoxyacetic acid, dicamba, mesotrione, isoxaflutole and quizalofop-p-ethyl (QpE) in 3T3-L1 adipocytes. Only QpE caused triglyceride accumulation from a concentration of 1 µM. We thus conducted an in-depth investigation of molecular mechanisms responsible for the adipogenic effects of quizalopfop-p-ethyl by an RNA-seq analysis.

New molecular insights into modulation of platelet reactivity in aspirin-treated patients using a network-based approach.
Specimen part
View SamplesPlatelet reactivity (PR) in cardiovascular (CV) patients is variable between individuals and modulates clinical outcome. However, the determinants of platelet reactivity are largely unknown. Integration of data derived from high-throughput omics technologies may yield novel insights into the molecular mechanisms that govern platelet reactivity. The aim of this study was to identify candidate genes modulating platelet reactivity in aspirin-treated cardiovascular patients PR was assessed in 110 CV patients treated with aspirin 100mg/d by aggregometry using several agonists. 12 CV patients with extreme high or low PR were selected for transcriptomics, proteomics and miRNA analysis.

View SamplesAs sessile organisms plants developed a veriety of adaptive responses to the ever changing environment. One of these responses is the shade avoidance syndrome which is composed of different responses like elongation growth, hyponastic leafs or early flowering to shade (low R/FR). Phytochrcome Interacting Factor 4 and 5 are bHLH transcription factors reported to activate gene expression upon perception of low R/FR. Using this miroarray experiment we identified new genes regulated by PIF4 and PIF5 in response to shade and investigated their genome wide role.
