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.

Project description:Epigenetic changes such as DNA cytosine methylation modulate gene function across brain and are implicated in the pathophysiology of neurodevelopmental disorders including schizophrenia and autism. Epigenetic changes can be caused by environmental exposures such as inflammation, and may at least partly explain why prenatal exposure to inflammation increase risk of neurodevelopmental disorders. We used an MIA mouse model to investigate the postnatal epigenetic changes associated with exposure to the viral analogue PolyI:C. The effect of dietary supplement with omega-3 polyunsaturated fatty acids (PUFA) on exposed mice was also examined. Methylation was estimated genome-wide across gene regulatory regions. Widespread epigenetic changes were observed following exposure to inflammation during prenatal life. The differentially methylated gene set was enriched for genes involved in nervous system development and function. Omega-3 intervention modified the epigenetic profile, including a number of genes which were affected by MIA. These experiments indicate that environmental and genetic risk factors modulate similar biological pathways that are associated with neurodevelopmental disorders.

Project description:Background: Prenatal alcohol exposure (PAE) is associated with alterations in numerous physiological systems, including the stress and immune systems. We have previously shown that PAE increases the course and severity of arthritis in an adjuvant-induced arthritis (AA) model. While the molecular mechanisms underlying these effects are not fully known, changes in neural gene expression are emerging as important factors in the etiology of PAE effects. As the prefrontal cortex (PFC) and hippocampus (HPC) play key roles in neuroimmune function, PAE-induced alterations to their transcriptome may underlie abnormal steady-state functions and responses to immune challenge. The current study examined brains from adult PAE and control females from our recent AA study to determine whether PAE causes long-term alterations in gene expression and whether these mediate the altered severity and course of arthritis in PAE females Methods: Adult females from PAE, pair-fed [PF], and ad libitum-fed control [C]) groups were injected with either saline or complete FreundM-bM-^@M-^Ys adjuvant. Animals were terminated at the peak of inflammation or during resolution (days 16 and 39 post-injection, respectively); cohorts of saline-injected PAE, PF and C females were terminated in parallel. Gene expression was analyzed in the PFC and HPC using whole genome mRNA expression microarrays. Results: Significant changes in gene expression in both the PFC and HPC were found in PAE compared to controls in response to ethanol exposure alone (saline-injected females), including genes involved in neurodevelopment, apoptosis, and energy metabolism. Moreover, in response to inflammation (adjuvant-injected females), PAE animals showed unique expression patterns, while failing to exhibit the activation of genes and regulators involved in the immune response observed in control and pair-fed animals. Conclusions: These results support the hypothesis that PAE affects neuroimmune function at the level of gene expression, demonstrating long-term effects of PAE on the CNS response under steady-state conditions and following an inflammatory insult.
