Male autism spectrum disorder is linked to brain aromatase disruption by prenatal BPA in multimodal investigations and 10HDA ameliorates the related mouse phenotype (BPA)

Project description:Pregannt Cyp19-EGFP mice (maintained on a soybean free mouse chow diet) were treated with either 50μg/kg/day Bsiphenol A or vehicle (ethinol in peanut oil) between gestational days (GD) 10.5-14.5. On GD15.5, fetuses were dissected and sex determined by SRY genotyping. Fetuses were obtained from different dams.

Male autism spectrum disorder is linked to brain aromatase disruption by prenatal BPA in multimodal investigations and 10HDA ameliorates the related mouse phenotype.

Project description:Male sex, early life chemical exposure and the brain aromatase enzyme have been implicated in autism spectrum disorder (ASD). In the Barwon Infant Study birth cohort (n = 1074), higher prenatal maternal bisphenol A (BPA) levels are associated with higher ASD symptoms at age 2 and diagnosis at age 9 only in males with low aromatase genetic pathway activity scores. Higher prenatal BPA levels are predictive of higher cord blood methylation across the CYP19A1 brain promoter I.f region (P = 0.009) and aromatase gene methylation mediates (P = 0.01) the link between higher prenatal BPA and brain-derived neurotrophic factor methylation, with independent cohort replication. BPA suppressed aromatase expression in vitro and in vivo. Male mice exposed to mid-gestation BPA or with aromatase knockout have ASD-like behaviors with structural and functional brain changes. 10-hydroxy-2-decenoic acid (10HDA), an estrogenic fatty acid alleviated these features and reversed detrimental neurodevelopmental gene expression. Here we demonstrate that prenatal BPA exposure is associated with impaired brain aromatase function and ASD-related behaviors and brain abnormalities in males that may be reversible through postnatal 10HDA intervention.

Project description:Primary cortical neurons were obtained from male Cyp19-EGFP mouse embryos at gestational day 15.5. Embryos were genotyped for SRY to determine sex, and only male embryos were used. Cells were seeded in 24-well plates containing 12 mm glass coverslips, coated with 100 µg/mL poly D-lysine to a density of ~0.45 x 106 cells/well and incubated in a humidified CO2 incubator (5% CO2, 37°C). Primary cortical from Cyp19-EGFP mouse embryos were obtained on GD 15.5. Neuronal cell cultures were treated with vehicle or 1mM 10HDA (Matreya, PA ,USA)
