The Transgenerational Effects of Prenatal Synthetic Glucocorticoids on the Prefrontal 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 (Beta and Control) have been extracted via micro-punch and RNA has been extracted.

Expression data from adult mouse Prefrontal Cortex following prenatal infection

Project description:Prenatal exposure to infectious or inflammatory insults can increase the risk of neuropsychiatric disorders with neurodevelopmental components, including schizophrenia and autism. The molecular processes underlying this pathological association are only partially understood. Here, we implemented an unbiased genome-wide transcriptional profiling of the prefrontal cortex of mice exposed to prenatal infection on GD17 compared to control subjects in order to elucidate the long term molecular signature of late prenatal infection. We used microarray analysis to investigate the long lasting gene expression changes in a well-established mouse model that is based on maternal treatment with the viral mimic poly(I:C) during pregnancy C57BL/6 mice were treated with the synthetic viral mimetic poly(I:C) (5 mg/kg, i.v.) or control (saline, i.v.) solution on gestation day 17. Offspring were subjected to cognitive and behavioral testing in adulthood, and then whole genome gene expression analysis with Affymetrix Microarray and subsequent q-PCR validation were performed on the prefrontal Cortex.

Transgenerational effects of prenatal synthetic glucocorticoids on hypothalamic-pituitary-adrenal function.

Project description:Approximately 10% of pregnant women are at risk of preterm delivery and receive synthetic glucocorticoids (sGC) to promote fetal lung development. Studies have indicated that prenatal sGC therapy modifies hypothalamic-pituitary-adrenal (HPA) function in first-generation (F(1)) offspring. The objective of this study was to determine whether differences in HPA function and behavior are evident in the subsequent (F(2)) generation. Pregnant guinea pigs (F(0)) received betamethasone (BETA; 1 mg/kg) or saline on gestational d 40/41, 50/51, and 60/61. F(1) females were mated with control males to create F(2) offspring. HPA function was assessed in juvenile and adult F(2) offspring. Locomotor activity was assessed in juvenile offspring. Analysis of HPA-related gene expression was undertaken in adult hippocampi, hypothalami, and pituitaries. Locomotor activity was reduced in F(2) BETA males (P < 0.05). F(2) BETA offspring displayed blunted cortisol response to swim stress (P < 0.05). After dexamethasone challenge, F(2) BETA males and females displayed increased and decreased negative feedback, respectively. F(2) BETA females had reduced pituitary levels of proopiomelanocortin (and adrenocorticotropic hormone), and corticotropin-releasing hormone receptor mRNA and protein (P < 0.05). F(2) BETA males displayed increased hippocampal glucocorticoid receptor (P < 0.001), whereas in BETA females, hippocampal glucocorticoid receptor and mineralocorticoid receptor mRNA were decreased (P < 0.05). In conclusion, prenatal BETA treatment affects HPA function and behavior in F(2) offspring. In F(2) BETA females, pituitary function appears to be primarily affected, whereas hippocampal glucocorticoid feedback systems appear altered in both F(2) BETA males and females. These data have clinical implication given the widespread use of repeat course glucocorticoid therapy in the management of preterm labour.

DNA methylome signatures of prenatal exposure to synthetic glucocorticoids in hippocampus and peripheral whole blood of female guinea pigs in early life

Project description:We examined the hypothesis that prenatal synthetic glucocorticoids (sGC) administration alters DNA methylation signatures in Guinea pig offspring hippocampus and whole blood. Guinea pigs were treated with sGC or saline in late gestation. Genome-wide modifications of DNA methylation were analyzed using reduced representation bisulfite sequencing in juvenile female offspring.
