Project description:TCDD is an environmental contaminant that elicits a number of hepatic effects including fat accumulation, inflammation, and fibrosis that can progress to hepatocellular carcinoma. RNA-Seq and targeted metabolomics were integrated with complementary dioxin response element (DRE) location and aryl hydrocarbon receptor (AhR) ChIP-Seq data to further investigate the hepatotoxicity of TCDD. Our integrative analysis identified changes similar to the Warburg effect observed in cancer cells, including pyruvate kinase isoform switching (PKM1 to PKM2), and an increase in the glutaminase (GLS1) GAC:KGA isoform ratio. Consequently, metabolites are redirected towards the pentose phosphate pathway, serine biosynthesis, and glutaminolysis. We propose that the effects of TCDD on central carbon and amino acid metabolism represents AhR-mediated hepatic metabolic reprogramming in order to increase NADPH production as an oxidative stress counter-measure.
Project description:This SuperSeries is composed of the following subset Series: GSE34902: Genome-wide Profiling of Progesterone Receptor and GATA2 Binding in the Mouse Uterus [Affymetrix] GSE34927: Genome-wide Profiling of Progesterone Receptor and GATA2 Binding in the Mouse Uterus [ChIP-Seq] Refer to individual Series
Project description:We report the application of Chip-seq to study the binding properties of C-maf. We determine the genetic and non genetic regions with the largest Chip-seq peaks in C-maf_ab compared to Isotype control antibody (Iso) samples.
Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.
