Gene expression in the F1 and F2 mouse hippocampus with intrauterine hyperglycemia exposure

Project description:Studies on human and animals suggest associations between gestational diabetes mellitus (GDM) with impaired cognitive performance in offspring. Using a mouse model of diabetes during pregnancy, we found that intrauterine hyperglycemia exposure resulted in memory impairment in both the first filial (F1) males and the second filial (F2) males from the F1 male offspring. The effects of intrauterine hyperglycemia exposure on F1 and F2 hippocampus gene expression were also examined.

Intrauterine hyperglycemia exposure per se altered metabolic functions in F2 offspring via reprogramming F1 PGCs

Project description:Intrauterine hyperglycemia has been linked to an elevated risk of diabetes in next and further generations. Existing reports about transmission effects of intrauterine hyperglycemia have included both intrauterine and postnatal metabolic exposure factors, the impact of intrauterine hyperglycemia per se has not been separately assessed. To investigate effect of intrauterine hyperglycemia exposure per se on further generations, we selected non-phenotypic F1-GDM and F2-GDM male mice to examin metabolic changes in next generation and performed a methylome on day 13.5 primordial germ cells (PGCs) of F1-GDM male fetus to explore its underlying mechanism. We found that intrauterine hyperglycemia exposure per se resulted in obesity, insulin resistance and/or glucose intolerance in F2 male mice, and no changes in F3 male mice. Methylome of day 13.5 PGCs of F1-GDM male fetus revealed differently methylation genes enriched in obesity and diabetic pathogenesis. Methylation validation of targeted gene Fyn showed consistent hypo-methylation status in F1 PGCs, F1 fetal testis, sperm of F1/N-GDM mice, and somatic cells of F2-GDM male mice. While fetal testis of F2-GDM mice showed no alteration in Fyn methylation. Our data indicates that intrauterine hyperglycemia exposure per se contributes to metabolic changes in F2 but not F3 generation, by altering methylation erasure in PGCs of F1 generation.

Epigenetic reprogramming of sperm in F1 adult male mice with intrauterine hyperglycemia exposure

Project description:Birth cohort studies and experimental investigations in animals link gestational diabetes mellitus (GDM) with impaired cognitive performance in the first filial generation (F1). We found that intrauterine hyperglycemia exposure resulted in behavior abnormality and cognitional functional disorder of both F1- and F2-GDM male mice. Methylome of sperm of F1 adult male mice from control pregnant mice (F1-C) and GDM pregnant mice (F1-GDM) revealed differentially methylated genes enriched in neurodevelopmental process.

Transcriptomic analyses in brains of exposed F0 zebrafish and their unexposed F1 and F2 offspring after early-life exposure to permethrin 10 microg/L

Project description:In the present study, zebrafish were exposed to permethrin during early-life, and F1 and F2 generations were bred unexposed. Permethrin exposed F0 fish showed a hypoactive phenotype at adulthood, whereas males from the F1 and F2 generations showed a decrease in anxiety-like behavior. Thus, we performed transcriptomic changes to identify underlying molecular mechanisms. They showed limited overlap between sex and generations. In F0, genes and pathways related to glutamatergic synapse activity (Gene Ontology and Reactome databases) were significantly enriched and may explain the behavioral effects. In F1 and F2 generations, mechanisms are less clear as limited changes which could correlate with behavior were observed in the F1 generation.

Transcription profiling of rat embryonic day 16 testis RNA samples from F1, F2, F3 generation control groups vs F1, F2, F3 generation vinclozolin treated groups to examine transgenerational epigenetic programming of the embryonic testis

Project description:Embryonic exposure to the endocrine disruptor vinclozolin during gonadal sex determination appears to promote an epigenetic reprogramming of the male germ line that is associated with transgenerational adult-onset disease states. Transgenerational effects on the embryonic day 16 (E16) testis demonstrated reproducible changes in the testis transcriptome for multiple generations (F1-F3). The expression of 196 genes was found to be influenced, with the majority of gene expression being decreased or silenced. Dramatic changes in the gene expression of methyltransferases during gonadal sex determination were observed in the F1 and F2 vinclozolin generation (E16) embryonic testis, but the majority returned to control-generation levels by the F3 generation. The most dramatic effects were on the germ-line-associated Dnmt3A and Dnmt3L isoforms. Observations demonstrate that an embryonic exposure to vinclozolin appears to promote an epigenetic reprogramming of the male germ line that correlates with transgenerational alterations in the testis transcriptome in subsequent generations. Experiment Overall Design: E16 Testis RNA samples from F1, F2, F3 generation control groups are compared to F1, F2, F3 generation vinclozolin treated groups

miRNA levels in F1-F3 male germ cells and female F2 PFC following prenatal exposure to sGC in guinea pigs

Project description:Stress and glucocorticoid exposure during pregnancy alters neurodevelopment and behavior in offspring, and these effects extend multiple generations through a paternal lineage. The epigenetic mechanisms that govern this transgenerational transmission are unclear. We hypothesized that maternal exposure to multiple courses of sGC in late pregnancy would result in altered miRNA levels in germs cells of male guinea pigs across three generations. Further, our behavioral data indicate that F2 females exhibit altered behaviors following sGC exposure. Thus, we evaluated the miRNA profile of F2 female prefrontal cortex to determine the mechanisms responsible for these behavioral changes and to compare these data to our germ cell miRNA analysis. We used miRNA microarray to evaluate the miRNA levels in F1-F3 germ cells and F2 female PFC in guinea pigs that were exposed to control and F0 prenatal sGC exposure. We identified no significant changes to miRNA levels in both F1-F3 germ cells and F2 PFC from guinea pigs in the sGC group.

The Transgenerational Effects of Prenatal Synthetic Glucocorticoids on the Hippocampus Cortex

Project description:First generation animals (F1) were exposed to multiple courses of synthetic glucocorticoids in utero. Animals were then bred to produce second (F2) and third (F3) generation offspring. These animals underwent behavioural assessmenets before sacrifice. In this experiment the prefrontal cortex for F1, F2, and F3 female animals, as well as F1 males (Control and sGC) have been extracted via micro-punch and RNA has been extracted.
