Alterations in sperm DNA Methylation, Non-Coding RNA expression, and histone retention mediate Vinclozolin induced epigenetic transgenerational inheritance of disease

Project description:Environmental factors have been shown to induce the epigenetic transgenerational inheritance of disease through the germline. This study was designed to investigate vinclozolin induced concurrent alterations of a number of different epigenetic processes including DNA methylation and histone retention in sperm. Gestating female rats were exposed transiently to vinclozolin during fetal gonadal development and then F1, F2 and F3 generation sperm were analyzed.

Developmental Origins of Transgenerational Sperm Histone Retention Following Ancestral Exposures

Project description:This study was designed to investigate the developmental origins of the transgenerational differential histone retention sites (called DHRs) during gametogenesis of the sperm. Vinclozolin and DDT were independently used to promote the epigenetic transgenerational inheritance of these DHRs. Male control, DDT lineage and vinclozolin lineage F3 generation rats were used to isolate round spermatids, caput epididymal spermatozoa, and caudal sperm. The DHRs between the control versus DDT lineage or vinclozolin lineage were determined in these three developmental stages. DHRs and a reproducible core of histone H3 retention sites were observed using an H3 chromatin immunoprecipitation (ChIP-Seq) analysis in the germ cell populations. The chromosomal locations and genomic features of the DHRs were also analyzed. A cascade of epigenetic histone retention site alterations was found to be initiated in or prior to the round spermatids that is further altered during epididymal sperm maturation. Observations show that in addition to alterations in sperm DNA methylation previously identified, the induction of differential histone retention sites (DHRs) in the later stages of spermatogenesis also occurs.

Developmental Origins of Transgenerational Sperm DNA Methylation Epimutations Following Ancestral Vinclozolin Exposure

Project description:Previously the agricultural fungicide vinclozolin was found to promote the transgenerational inheritance of sperm differential DNA methylation regions (DMRs) termed epimutations that help mediate this epigenetic inheritance. The current study was designed to investigate the developmental origins of the transgenerational DMRs during gametogenesis. Male control and vinclozolin lineage F3 generation rats were used as a source of embryonic day 16 (E16) prospermatogonia, postnatal day 10 (P10) spermatogonia, and adult pachytene spermatocytes, round spermatids, caput epididymal sperm, and caudal sperm. The DMRs between the control versus vinclozolin lineage samples were determined for each developmental stage. The top 100 statistically significant DMRs for each stage were compared and the developmental origins of the caudal epididymal sperm DMRs were assessed.

Environmentally Induced Epigenetic Transgenerational Inheritance of Somatic Transcriptomes

Project description:Environmentally induced epigenetic transgenerational inheritance of adult onset disease involves a variety of phenotypic changes suggesting a general alteration in genome activity. Investigation of eleven different tissue transcriptomes in male and female F3 generation vinclozolin versus control lineage rats demonstrated all tissues examined had unique transgenerational transcriptomes. Common cellular pathways and processes were identified among the tissues. A bionetwork analysis identified gene modules with coordinated gene expression and each had unique gene networks regulating tissue specific gene expression and function. A large number of statistically significant over-represented clusters of differentially expressed genes were identified and termed M-bM-^@M-^\Epigenetic Control RegionsM-bM-^@M-^]. Combined observations demonstrate that all tissues derived from the epigenetically altered germ line develop transgenerational transcriptomes unique to the tissue, but common epigenetic control regions in the genome appear to in part coordinately regulate these tissue specific transcriptomes. This systems biology approach provides insight into the molecular mechanisms involved in the epigenetic transgenerational inheritance of a variety of adult onset disease phenotypes. We used microarrays to determine genes expressed differentially in rats 11 male or female smatic tissues -male heart, kidney, liver, testis, prostate, seminal vesicles; female heart, kidney, liver, ovary, uterus - due to Vinclozolin treatments of their grand-grandmothers. For each of 11 male or female smatic tissues, RNA samples from 2 treatment groups - control (Con) and vinclozolin (Vin) - were compared to each other. Each treatment groups contained 3 biological replica. RNA for each replica was pooled from 2 individual animals.

Epigenetic Transgenerational Inheritance of Altered Sperm Histone Retention Sites

Project description:Female and male rats of an outbred female Sprague Dawley rats were administered daily intraperitoneal injections of vinclozolin (100 mg/kg BW/day), or DDT (25 mg/kg BW/day) or dimethyl sulfoxide (DMSO) in oil (1 µl/kg BW/day vehicle). Treatment lineages are designated “control” or “vinclozolin” or “DDT” lineages. The gestating female rats treated were designated as the F0 generation. The offspring of the F0 generation rats were the F1. Non-littermate females and males aged 70-90 days from F1 generation of control, vinclozolin or DDT were bred to obtain F2 generation offspring. The F2 generation rats were similarly bred to obtain the F3 generation offspring. Individuals were maintained for 120 days and euthanized for sperm collection. Sperm from multiple individual rats was pooled into single samples. For the control samples, 2 pools were made using 6 animals and 1 pool with 5 animals. For the DDT samples, 3 pools were mady using 4 animals. For the Vinclozolin samples, 3 pools were made using 4 animals. Genomic DNA was isolated and histone chromatin immunoprecipitation with genomic DNA was performed. Each pooled sample received a separate index primer. NGS was performed at the WSU Spokane Genomics Core using Ilumina HiSeq 2500 with a PE50 application, with a read size of approximately 50 bp and approximately 35 million reads per pool.

Environmental Toxicants Induce Epigenetic Transgenerational Inheritance of Ovarian Disease

Project description:The epigenetic transgenerational actions of environmental toxicants and relevant mixtures on ovarian disease was investigated with the use of a fungicide, a pesticide mixture, a plastic mixture, dioxin and a hydrocarbon mixture. After transient exposure of an F0 gestating female rat during embryonic gonadal sex determination, the F1, F2 and F3 generation progeny adult onset ovarian disease was assessed. Transgenerational disease phenotypes observed included an increase in cysts resembling human polycystic ovarian disease (PCO) and a decrease in the ovarian primordial follicle pool size resembling premature ovarian failure (POF). The F3 generation granulosa cells were isolated and found to have a transgenerational effect on the transcriptome and epigenome (differential DNA methylation). Epigenetic biomarkers for environmental exposure and associated gene networks were identified. Epigenetic transgenerational inheritance of ovarian disease states were induced by different classes of environmental compounds suggesting a role of environmental epigenetics in ovarian disease etiology. We used transcriptome microarray analysis to determine genes expressed differentially between F3 control and F3 vinclozolin lineage rat ovary granulosa cell and see which genes might be connected to or cause observed ovary diseases RNA samples from granulosa cell of 3 F3-control lineage groups are compared to granulosa cell of 3 F3-vinclozolin lineage groups
