Project description:The opioid epidemic has received considerable attention, but the impact on perinatal opioid-exposed (POE) offspring remains underexplored. This study addresses the emerging public health challenge of understanding and treating POE children. We examine two scenarios using preclinical models: offspring exposed to oxycodone (OXY) in utero (IUO) and postnatally (PNO). We hypothesized exposure to OXY during pregnancy primes offspring for neurodevelopmental deficits and severity of deficits is dependent on timing of exposure. Notable findings include reduced head size and brain weight in offspring. Molecular analyses revealed significantly lower levels of inflammasome-specific genes in the prefrontal cortex (PFC). Gene Set Enrichment Analysis (GSEA) and Ingenuity Pathway Analysis (IPA) highlighted the enrichment of genes associated with mitochondrial and synapse dysfunction in POE offspring. Western blot analysis validated IPA predictions of mitochondrial dysfunction in PFC-derived synaptosomes. Behavioral studies identified significant social deficits in POE offspring. This study presents the first comparative analysis of PNO- and IUO-offspring during early adolescence finding PNO-offspring have considerably greater deficits. The striking difference in deficit severity in PNO-offspring suggests that exposure to opioids in late pregnancy pose the greatest risk for offspring well-being.

Project description:Perinatal nutritional imbalances may have long-lasting consequences on health and disease, increasing risk of obesity, insulin resistance, type 2 diabetes or cardiovascular disease. This idea has been conceptualized in the Developmental Origins of Health and Disease Hypothesis (DOHaD). In addition, there is evidence that such early-programmed phenotypes can be transmitted to the following generation(s). It is proposed that, environmentally induced, transmission of disease risk is mediated by epigenetic mechanisms. The aim of this study was to determine whether patterns of gene expression in the first generation offspring are also present in the following generation offspring, via the paternal lineage. Paternal transmission of patterns of gene expression strongly suggest epigenetic inheritance of disease risk. Liver tissue was obtained from the follwing experimental groups: a) control male mice, b) adult male mice previously exposed to 50% caloric restriction in utero (IUGR), c) adult male mice overfed during lactation (ON), d) adult male offspring from control mice, e) adult male offspring from IUGR mice and f) adult male offspring from ON mice.RNA was extracted and processed for further hybridization on Affymetrix microarrays (GeneChip Mouse Genome 430 2.0 (Affymetrix, Santa Clara, CA)).

Project description:Aside from the perinatal complications associated with low birth weight, individuals born with intra-uterine growth restriction suffer from chronic diseases late in life that ultimately lead to a shortened lifespan. These late life metabolic sequelae of low birth weight include obesity and metabolic syndrome, diabetes mellitus, cardiovascular disease, hypertension, stroke, dyslipidemia, and non-alcoholic fatty liver disease/steatohepatitis. Animal models employing perinatal calorie restriction recapitulate the observations made in humans. Interestingly, if continued calorie restriction is employed post-natally the late life sequelae of intra-uterine growth restriction are ameliorated. These observations linking both fetal and early post natal growth to later health is now termed the developmental origins of health and disease. To further our understanding of the mechanism of how early growth affects late life health we have employed Affymetrix microarray-based expression profiling to characterize hepatic gene expression in a rat model of maternal semi-nutrient restriction. In these experiments we have limited maternal calorie intake to 50% of normal so as to create 3 groups of animals: Control (Con) male offspring born to mothers who were fed normally throughout gestation and lactation; intra-uterine calorie restricted male offspring (IUCR) born to mothers who had 50% restriction of calories from e11 to e21; and combined intra-uterine and post-natal calorie restriction (IPCR) male offspring who were born to mothers who received calorie restriction during both fetal growth (e11 to e21) and post-natally (p1-p21). Livers were collected at p21(day 21 of life) for Con and IPCR groups (IUCR withheld owing to ‘catch up” growth), and at p450 (day 450 of life) for Con, IUCR, and IPCR. The profiling data reveals clear alteration of circadian cycling at P21, and subtle changes for circadian gene expression at p450. In addition, a clear transcriptional response is found during active calorie restriction at p21 but an absence of a transcriptional response late in life at p450. Transcritional studies have been performed using Affymetrix Rat Gene 1.0 arrays for the following treatment groups, with each group run in triplicate (each replicate from separate littermates): Day 21 Control, Day 21 IPCR, Day 450 Con, Day 450 IUCR, Day 450 IPCR

Project description:Selective serotonin reuptake inhibitor (SSRI) antidepressants are the mainstay treatment for the 10-20% of pregnant and postpartum women who suffer major depression, but the effects of SSRIs on their children’s developing brain and later emotional health are poorly understood. SSRI use during pregnancy can elicit antidepressant withdrawal in newborns and increase toddlers’ anxiety and social avoidance. In rodents, perinatal SSRI exposure increases adult depression- and anxiety-like behavior, although certain individuals are more vulnerable to these effects than others. Our study establishes a rodent model of individual differences in susceptibility to perinatal SSRI exposure, utilizing selectively-bred Low Responder (LR) and High Responder (HR) rats that were previously bred for high versus low behavioral response to novelty. Pregnant HR/LR females were chronically treated with the SSRI paroxetine (10 mg/kg/day p.o.) to examine its effects on offspring’s emotional behavior and gene expression in the developing brain. Paroxetine treatment had minimal effect on HR/LR dams’ pregnancy outcomes or maternal behavior. We found that LR offspring, naturally prone to an inhibited/anxious temperament, were susceptible to behavioral abnormalities associated with perinatal SSRI exposure (which exacerbated their Forced Swim Test immobility), while high risk-taking HR offspring were resistant. Microarray studies revealed robust perinatal SSRI-induced gene expression changes in the developing LR hippocampus and amygdala (postnatal days 7-21), including transcripts involved in neurogenesis, synaptic vesicle components, and energy metabolism. These results highlight the LR/HR model as a useful tool to explore the neurobiology of individual differences in susceptibility to perinatal SSRI exposure.

Project description:Environmental factors during perinatal development influence developmental plasticity and disease susceptibility via alterations to the epigenome. Developmental exposure to the endocrine active compound, bisphenol A (BPA), has previously been associated with altered methylation at candidate gene loci. Here, we undertake the first genome-wide characterization of DNA methylation profiles in the liver of murine offspring perinatally exposed to multiple doses of BPA through the maternal diet. Using a tiered focusing approach, our strategy proceeds from unbiased broad DNA methylation analysis using methylation-based next generation sequencing technology to in-depth quantitative site-specific CpG methylation determination using the Sequenom EpiTYPER MassARRAY platform to profile liver DNA methylation patterns in offspring maternally exposed to BPA during gestation and lactation to doses ranging from 0 BPA/kg (Ctr), 50 M-BM-5g BPA/kg (UG), or 50 mg BPA/kg (MG) diet (N=4 per group). Genome-wide analyses indicate non-monotonic effects of DNA methylation patterns following perinatal exposure to BPA, corroborating previous studies using multiple doses of BPA with non-monotonic outcomes. We observed enrichment of regions of altered methylation (RAMs) within CpG island (CGI) shores, but little evidence of RAM enrichment in CGIs. An analysis of promoter regions identified several hundred novel BPA-associated methylation events, and methylation alterations in the Myh7b and Slc22a12 gene promoters were validated. Using the Comparative Toxicogenomics Database, a number of candidate genes that have previously been associated with BPA-related gene expression changes were identified, and gene set enrichment testing identified epigenetically dysregulated pathways involved in metabolism and stimulus response. In this study, non-monotonic dose dependent alterations in DNA methylation among BPA-exposed mouse liver samples and their relevant pathways were identified and validated. The comprehensive methylome map presented here provides candidate loci underlying the role of early BPA exposure and later in life health and disease status. For this study, liver DNA from a subset of a/a wild-type animals was analyzed for full methylome characteristics: 1) standard diet (Ctr, n = 4 offspring; 2 male and 2 female); 2) 50 M-BM-5g BPA/kg diet (UG, n = 4 offspring; 2 male and 2 female); 3) 50 mg BPA/kg diet (MG, n = 4 offspring; 1 male and 3 female).

Project description:Chronic Kidney Disease (CKD), a global health burden, is strongly associated with age-related renal function decline, hypertension and diabetes, frequent consequences of obesity. Despite extensive studies the mechanisms determining susceptibility to CKD remain elusive. Clinical evidence together with prior studies from our group showed that perinatal metabolic disorders after maternal obesity adversely affect kidney structure and function throughout life. Since obesity and aging processes converge in similar pathways we tested if perinatal obesity induced by High-Fat Diet (HFD)-fed female mice sensitizes aging-associated mechanism in kidneys of newborn mice. Tissue from the kidney cortex and the kidney medulla was collected from offspring of control or HFD-fed mice.

Project description:Opioid use during pregnancy can lead to negative infant health outcomes, including neonatal opioid withdrawal syndrome (NOWS). NOWS comprises gastrointestinal, autonomic nervous system, and neurological dysfunction that manifest during spontaneous withdrawal. Current treatments involve non-pharmacological and pharmacological interventions, however, there is no one standardized approach, in part because of variability in NOWS severity. To effectively model NOWS traits in mice, we used a third trimester-approximate opioid exposure paradigm, where neonatal inbred FVB/NJ and outbred Carworth Farms White (CFW) pups were injected twice-daily with morphine (10-15 mg/kg, s.c.) or saline (0.9%, 20 ul/g, s.c.) from postnatal day (P) one to P14. We observed reduced body weight gain, hypothermia, thermal hyperalgesia, and increased ultrasonic vocalizations (USVs). Neonatal USVs are emitted exclusively in isolation to communicate distress and thus serve as a model behavior for affective states. On P14, we observed altered USV syllable profiles during spontaneous morphine withdrawal, including an increase in Complex 3 syllables in FVB/NJ females (but not males) and in CFW mice of both sexes. Brainstem transcriptomics revealed an upregulation of the kappa opioid receptor (Oprk1), whose activation has previously been shown to contribute to withdrawal-induced dysphoria. Treatment with the kappa opioid receptor (KOR) antagonist, nor-BNI (30 mg/kg, s.c.), significantly reduced USV emission in FVB/NJ females, but not FVB/NJ males during spontaneous morphine withdrawal. Furthermore, treatment with the KOR agonist, U50,488h (0.625 mg/kg, s.c.), was sufficient to increase USV emission on P10 (both sexes) and on P14 (females only) in FVB/NJ mice. Together, these results indicate a female-specific recruitment of the dynorphin/KOR system in neonatal opioid withdrawal symptom severity.
