Project description:We investigated the impact of prenatal exposure to DEHP on spermatogenesis and DNA sperm methylation in F1 mice strains FVB/N and C57BL/6J. Prenatal exposition was performed orally on mothers with 300 mg/kg/day of DEHP from gestation day 9 to 19. 20 sperm-extracted DNA samples of males born from DEHP-treated and control mothers were analysed by MBD-seq at NXT-DX company.

Project description:BACKGROUND: Phthalates are manmade industrial additives used mostly as plasticizers. In addition to their deleterious effects on male genital development, population studies have recently documented correlations between phthalates exposure and subtle impacts on reproductive tract development and on the metabolic syndrome in male adults. In mature rodents liver di-(2-ethylhexyl)-phthalate (DEHP) activates the peroxisome proliferators-activated receptor (PPARalpha), a member of the nuclear receptor (NR) superfamily. OBJECTIVES: Using a systems biology approach, we aimed at defining potential mechanisms underlying the impacts of DEHP on adult mouse liver and testis. METHODS: Thus, we performed a parallel analysis of transcript and metabolic profiles in the liver from adult mice exposed to varying DEHP doses. Moreover, we obtained pangenomic mRNA profiles of laser-captured Leydig and Sertoli cells from mature animals exposed to DEHP. RESULTS: Hepatic genes modulated by DEHP are predominantly PPARalpha targets. However, the induction of some prototypic cytochrome P450 genes strongly supports the activation of additional NR pathways. Integration of hepatic transcriptomic and metabonomic profiles further revealed a correlation between the impacts of DEHP on a cluster of genes and metabolites linked to heme synthesis and on a cluster of Rev-erbalpha target genes related to metabolic and circadian clock pathways. Cell-specific effects of DEHP were investigated in the adult testis and a noticeable impact of DEHP was observed on Leydig cells transcriptome. CONCLUSIONS: We report a detailed analysis of DEHP interference with hepatic Constitutive Androstane Receptor (CAR) and Rev-erbalpha pathways and a novel transcriptional impact of DEHP on adult endocrine cells of the testis.

Project description:Purpose: Then goal of this study id to investigate the effects of perinatal lead (32 ppm in maternal drinking water) and DEHP (25 mg per kg of chow) exposure on liver and blood DNA methylation in both PND21 and 5-month male and female mice. Methods: Enhanced reduced-representation bisulfite sequencing (ERRBS) was used to assess DNA methylation in PND21 and 5-month old DEHP-exposed, lead-exposed and control mice. Sex-specific differential methylaton analysis by DEHP and lead exposure was conducted using MethylSig R package. Results: We observed hundreds to thousands of stably modified, sex-specific differentially methylated regions in blood and liver of DEHP-exposed and lead-exposed animals at both PND21 and 5 months.

Project description:Role of PPARalpha in the effects of DEHP on the hepatic expression of a selection of mouse genes related to nuclear receptor signaling. Di-(2-ethylhexyl)-phthalate (DEHP), a widely used plasticizer, is detected in consumer’s body fluids. Contamination occurs through environmental and food chain sources. In mouse liver, DEHP activates the peroxisome proliferator-activated receptor alpha (PPARalpha) and regulates the expression of its target genes. Several in vitro investigations support the simultaneous recruitment of additional nuclear receptor pathways. We investigated, in vivo, the hepatic impact of low doses of DEHP on PPARalpha activation, and the putative activation of additional signalling pathways. Wild-type and PPARalpha-deficient mice were exposed to different doses of DEHP. Gene expression profiling delineated the role of PPARalpha and revealed a PPARalpha-independent regulation of several prototypic Constitutive Androstane Receptor (CAR) target genes. This finding demonstrates that CAR also represents a transcriptional regulator sensitive to phthalates. CAR-mediated effects of DEHP provide a new rationale for most endpoints of phthalates toxicity described previously, including endocrine disruption, hepatocarcinogenesis and the metabolic syndrome.
