Loss of IL-10 signaling in macrophages (Mφs) leads to inflammatory bowel disease (IBD). Induced pluripotent stem cells (iPSCs) were generated from an infantile-onset IBD patient lacking a functional IL10RB gene. Mφs differentiated IL-10RB−/− iPSCs lacked IL-10RB mRNA expression, unable phosphorylate STAT3, and failed reduce LPS induced cytokines the presence exogenous IL-10. exhibited striking defect their ability kill Salmonella enterica serovar Typhimurium, which was rescuable after...

Abstract Epidemiologic and experimental studies have associated changes of blood glucose homeostasis to Bisphenol A (BPA) exposure. We took a toxicogenomic approach investigate the mechanisms low-dose (1 × 10 −9 M) BPA toxicity in ex vivo cultures primary murine pancreatic islets hepatocytes. Twenty-nine inhibited genes were identified none exposed Although their expression was slightly altered, impaired cellular level, as whole, resulted specific phenotypic changes. Damage mitochondrial...

Abstract The brain‐derived neurotrophic factor ( BDNF ) gene is expressed in differentiating and post‐mitotic neurons of the zebrafish embryo, where it has been implicated Huntington's disease. Little known, however, about full complement neuronal cell types that express this important vertebrate model. Here, we further explored transcriptional profiles during first week development using real‐time quantitative polymerase chain reaction (RT‐ qPCR whole‐mount situ hybridization (WISH). RT‐...

Epidemiological and experimental data highlighted the thyroid-disrupting activity of bisphenol A (BPA). Although pivotal to identify mechanisms toxicity, direct low-dose BPA effects on thyrocytes have not been assessed. Here, we report results microarray experiments revealing that transcriptome reacts dynamically exposure, adapting changes in gene expression exposure duration. The response involves many genes, enriching specific pathways biological functions mainly cell death/proliferation...

Abstract In vitro Omics analysis (i.e. transcriptome) is suggested to predict in vivo toxicity and adverse effects humans, although the causal link between high-throughput data not easily established. Indeed, chemical-organism interaction can involve processes, such as adaptation, established cell cultures. Starting from this consideration we investigate transcriptomic response of immortalized thyrocytes ethylenthiourea chlorpyrifos. revealed specific common genes/mechanisms toxicity,...

chlorpyrifos (CPF) is an organophosphate insecticide used to control pests on a variety of food and feed crops. In mammals, maternal exposure CPF has been reported induce cerebral cortex thinning, alteration long-term brain cognitive function, Parkinson-like symptoms, but the mechanisms these processes are not fully understood. this study, we aimed gain deeper understanding alterations induced in brains mice chronically exposed by dietary intake. For our purpose, analysed F1 offspring...

Gene editing technologies hold promise for enabling the next generation of adoptive cellular therapies. In conventional gene platforms that rely on nuclease activity, such as clustered regularly interspaced short palindromic repeats CRISPR-associated protein 9 (CRISPR-Cas9), allow efficient introduction genetic modifications; however, these modifications occur via DNA double-strand breaks (DSBs) and can lead to unwanted genomic alterations genotoxicity. Here, we apply a novel modular RNA...

Thyroid hormones (THs) regulate many biological processes in vertebrates, including reproduction. Testicular somatic and germ cells are equipped with the arrays of enzymes (deiodinases), transporters, receptors necessary to locally maintain optimal level THs their signalling, needed for functions spermatogenesis. Pesticides, as chlorpyrifos (CPF) ethylene thiourea (ETU), impair function thyroid testis, affecting male fertility. However, ability disarrange testicular T3 (t-T3) metabolism...

The paired-type homeodomain transcription factor Uncx is involved in multiple processes of embryogenesis vertebrates. Reasoning that zebrafish genes uncx4.1 and uncx are orthologs mouse , we studied their genomic environment developmental expression. Evolutionary analyses indicate the as being paralogs deriving from teleost-specific whole-genome duplication. Whole-mount situ mRNA hybridization transcripts embryos reveals novel expression domains, confirms those previously known, suggests...

Abstract Genetic and environmental factors contribute to thyroid diseases. Although still debated, 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD) is thought induce dysfunction in humans rodents. The data here reported point out the contribution of exposure window genetic background mediating low-dose TCDD effects on thyroid. Indeed, early (from E0.5 PND30) (0,001 μg/kg/day) reduced circulating fT4 altered expression specific transcripts. role components was estimated monitoring same markers...
