The fetal cortical neuroepithelium is a mosaic of distinct progenitor populations that elaborate diverse cellular fates. Ethanol induces apoptosis and interferes with the survival of differentiating neurons. However, we know little about ethanol's effects on neuronal progenitors. We therefore exposed neurosphere cultures from fetal rat cerebral cortex, to(More)
Extensive changes in DNA methylation have been observed in schizophrenia (SC) and bipolar disorder (BP), and may contribute to the pathogenesis of these disorders. Here, we performed genome-scale DNA methylation profiling using methylated DNA immunoprecipitation followed by sequencing (MeDIP-seq) on two brain regions (including frontal cortex and anterior(More)
Ethanol is a significant neuroteratogen. We previously used fetal cortical-derived neurosphere cultures as an ex vivo model of the second trimester ventricular neuroepithelium, and showed that ethanol directly induced fetal stem and progenitor cell proliferation and maturation without inducing death. However, ethanol is defined as a teratogen because of its(More)
Schizophrenia is a chronic and debilitating psychiatric condition affecting slightly more than 1% of the population worldwide and it is a multifactorial disorder with a high degree of heritability (80%) based on family and twin studies. Increasing lines of evidence suggest intermediate phenotypes/endophenotypes are more associated with causes of the disease(More)
Schizophrenia (SZ) and bipolar disorder (BP) are complex genetic disorders. Their appearance is also likely informed by as yet only partially described epigenetic contributions. Using a sequencing-based method for genome-wide analysis, we quantitatively compared the blood DNA methylation landscapes in SZ and BP subjects to control, both in an understudied(More)
A genome-wide nonparametric linkage screen was performed to localize Bipolar Disorder (BP) susceptibility loci in a sample of 3757 individuals of Latino ancestry. The sample included 963 individuals with BP phenotype (704 relative pairs) from 686 families recruited from the US, Mexico, Costa Rica, and Guatemala. Non-parametric analyses were performed over a(More)
The Neuregulin 3 (NRG3) gene at 10q22–q24 has been implicated in multiple psychiatric traits such as cognitive impairment. We therefore hypothesized that NRG3 gene polymorphisms may play a role in Alzheimer disease (AD). This present study explored the association of NRG3 with the age at onset (AAO) of AD and the risk of developing AD. Secondary data(More)
With the trend of an increasing aged population worldwide, Alzheimer's disease (AD), an age-related neurodegenerative disorder, as one of the major causes of dementia in elderly people is of growing concern. Despite the many hard efforts attempted during the past several decades in trying to elucidate the pathological mechanisms underlying AD and putting(More)
During the second trimester period, neuroepithelial stem cells give birth to millions of new neuroblasts, which migrate away from their germinal zones to populate the developing brain and terminally differentiate into neurons. During this period, large numbers of cells are also eliminated by programmed cell death. Therefore, the second trimester constitutes(More)
Schizophrenia (SCZ) is a debilitating disorder with a prevalence of approximately 1 % worldwide. SCZ is known to have a high degree of genetic and clinical heterogeneity and is a major health problem worldwide. The integrin-β 3 subunit gene (ITGB3) gene at 17q21.32 has been implicated in psychiatric disorders. We therefore hypothesized that ITGB3 gene(More)
