Epigenomics of rat born to dams fed a diet deficient in methyl group donors (MDD)

ABSTRACT: It is clearly established that the maternal diet during pregnancy can induce physiological and metabolic adaptations in the developing fetus which determine its susceptibility later in life to develop diabetes, obesity... The molecular and genomic mechanisms underlying the programming of the metabolic syndrome remain largely unknown but may involve resetting of epigenetic marks and fetal gene expression. We analyzed the profile of the liver methylome in 21-day-old rats born to mothers fed with a standard diet or a diet lacking methyl donor nutrients (Vitamin B12 and folates) during gestation and lactation. Modifications of DNA methylation were found in the promoter regions of 1,032 genes out of 14,981 genes. Bioinformatics analysis revealed that these genes are mainly involved in glucose and lipid metabolism, nervous system, coagulation, endoplasmic reticulum (ER) stress and mitochondrial function. MDD induced modifications of methylation in rat liver were measured in 21-day-old rats born to dams fed with standard food or food deficient in methyl group donor. Six independent experiments were performed (3 controls versus 3 MDD).

<h4>Scope</h4>Our study aims to investigate molecular events associated to methyl donor deficiency (MDD) by analyzing the transcriptome and the methylome of MDD rats in liver.<h4>Methods and results</h4>Twenty-one-day-old rats born to mothers fed either with a standard diet or a MDD diet during gestation and lactation were compared. From a total of 44 000 probes for 26 456 genes, we found two gene clusters in MDD rats whose expression levels had significant differences compared with controls: 32 ...[more]

Project description:Evidence suggests that epigenetic perturbations are involved in the adverse effects associated with some drugs and toxicants, including certain classes of non-genotoxic carcinogens. Such epigenetic changes (altered DNA methylation and covalent histone modifications) may take place at the earliest stages of carcinogenesis and their identification holds great promise for biomedical research. Here, we evaluate the sensitivity and specificity of genome-wide epigenomic and transcriptomic profiling in phenobarbital (PB)-treated B6C3F1 mice, a well-characterized rodent model of non-genotoxic liver carcinogenesis. Methylated DNA Immunoprecipitation (MeDIP)-coupled microarray profiling of 17,967 promoter regions and 4,566 intergenic CpG islands was combined with genome-wide mRNA expression profiling to identify liver tissue-specific PB-mediated DNA methylation and transcriptional alterations. Only a limited number of significant anti-correlations were observed between PB-induced transcriptional and promoter-based DNA methylation perturbations. However, the constitutive androstane receptor (CAR) target gene Cyp2b10 was found to be concomitantly hypomethylated and transcriptionally activated in a liver tissue-specific manner following PB treatment. Furthermore, analysis of active and repressive histone modifications using chromatin immunoprecipitation revealed a strong PB-mediated epigenetic switch at the Cyp2b10 promoter. Our data reveal that PB-induced transcriptional perturbations are not generally associated with broad changes in the DNA methylation status at proximal promoters and suggest that the drug-inducible CAR pathway regulates an epigenetic switch from repressive to active chromatin at the target gene Cyp2b10. This study demonstrates the utility of integrated epigenomic and transcriptomic profiling for elucidating early mechanisms and biomarkers of non-genotoxic carcinogenesis. 29M-bM-^@M-^S32 days old male B6C3F1/Crl (C57BL/6 M-bM-^YM-^B x C3H/He M-bM-^YM-^@) mice were obtained from Charles River Laboratories (Germany). Animals were allowed to acclimatise for 5 days prior to being randomly divided into two treatment groups (n = 10) and phenobarbital (Sigma 04710, 0.05% (w/v) in drinking water) was administered to one group through ad libitum access to drinking water for 28 days. Mice were checked daily for activity and behavior and sacrificed on the last day of dosing (day 28). Blood was withdrawn for PK analysis and target (liver) and non-target (kidney) tissues removed, split into several sections, frozen in liquid nitrogen and stored at M-bM-^HM-^R80M-BM-0C for subsequent analyses. Total RNA from liver and kidney was purified and processed for Affymetrix gene expression profiling while genomic DNA was prepared for promoter array based methylome analysis using the Methylated DNA immunoprecipitation (MeDIP) procedure. Remaining tissue material was used for chromatin immunoprecipitation (ChIP) to analyze histone modifications at individual promoters. Plasma samples were also collected to evaluate phenobarbital exposure in individual animals by LC-MS.

Project description:MicroRNAs (miRNAs) are a class of small non-coding RNAs that function as post-transcriptional regulators of gene expression. Many miRNAs are expressed in the developing brain and regulate multiple aspects of neural development including neurogenesis, dendritogenesis and synapse formation. Rett syndrome (RTT) is a progressive neurodevelopmental disorder caused by mutations in the gene encoding Methyl-CpG binding protein 2 (MECP2). While Mecp2 is known to act as a global transcriptional regulator, miRNAs that are directly regulated by Mecp2 in the brain are not known. Using massively parallel sequencing methods, we have identified miRNAs whose expression is altered in cerebella of Mecp2-null mice before and after the onset of severe neurological symptoms. In vivo genome-wide analyses indicate that promoter regions of a significant fraction of dys-regulated miRNA transcripts, including a large polycistronic cluster of brain-specific miRNAs, are DNA methylated and directly bound by Mecp2. Functional analysis demonstrates that the 3’ untranslated region (UTR) of messenger RNA encoding Brain-derived neurotrophic factor (Bdnf) can be targeted by multiple miRNAs aberrantly up-regulated in absence of Mecp2. Taken together, these results suggest that dys-regulation of miRNAs may contribute to RTT pathoetiology, and also provide a valuable resource to further investigate the role of miRNAs in RTT. Chromatin extracted from postnatal 6-8 week old cerebellar (CB) tissues of wild-type (WT) or Mecp2-null (KO) male mice was immunoprecipitated with indicated antibodies and analyzed by NimbleGen custom mouse 385K promoter tiling microarrays (a 2-array set covering the promoter regions of all Refseq protein-coding genes and miRNA transcripts with predicted transcription start sites). Whole cell extract (WCE) was used as input controls in all experiments. DNA methylation profiles in WT CB were also analyzed by methylated DNA immunoprecipitation (MeDIP) followed by hybridization to the same promoter tiling microarrays (MeDIP-chip).
