While cerebral underdevelopment is a hallmark of fetal alcohol spectrum disorders (FASD), the mechanism(s) guiding the broad cortical neurodevelopmental deficits are not clear. DNA methylation is known to regulate early development and tissue specification through gene regulation. Here, we examined DNA methylation in the onset of alcohol-induced cortical thinning in a mouse model of FASD. C57BL/6...
Binge-like alcohol exposure during the early postnatal period in rats and mice causes deficits in spatial learning and memory that persist into adulthood. Wozniak et al. (2004) reported that heavy binge alcohol exposure on postnatal day 7 (PD 7) in C57BL/6 (B6) mice produced profound spatial learning deficits in the Morris water maze when tested in adolescence (P30–39); when tested in adulthood, however,...
Craniofacial bone dysmorphology is an important but under-explored potential diagnostic feature of fetal alcohol spectrum disorders. This study used longitudinal MicroCT 3D imaging to examine the effect of prenatal alcohol exposure on craniofacial bone growth in a mouse model. C57BL/6J dams were divided into 3 groups: alcohol 4.2% v/v in PMI ® liquid diet (ALC), 2 weeks prior to and during...
The annual meeting of the Fetal Alcohol Spectrum Disorders Study Group (FASDSG) was held on June 20, 2009 in San Diego, CA, as a satellite of the Research Society on Alcoholism Meeting. The FASDSG membership includes clinical, basic, and social scientists who meet to discuss recent advances and issues in Fetal Alcohol Spectrum Disorders research. The main theme of the meeting was “Epigenetics and...
Alcohol consumption during pregnancy causes fetal alcohol spectrum disorder (FASD), which includes a range of developmental deficits. Fetal alcohol syndrome is the most severe form of FASD and can be diagnosed with pathognomonic facial features such as a smooth philtrum, short palpebral fissure, and thin upper vermilion. However, many children with developmental damage because of prenatal alcohol...
The annual meeting of the Fetal Alcohol Spectrum Disorders Study Group (FASDSG) was held on June 28, 2008 in Washington DC, as a satellite to the Research Society on Alcoholism meeting. The FASDSG membership includes clinical, basic, and social scientists who meet to discuss recent advances and issues in FASD research. The main theme of the meeting was “Factors that Influence Brain and Behavioral...
Alcohol has been shown to affect glutamate (GLU) and dopamine (DA) release and their correlated receptors in the key reward center—extended amygdala—which includes the shell of nucleus accumbens (sNAc) and central nucleus of amygdala (cAmg). It is unclear to date whether there is an alteration in the number of presynaptic GLU/DA nerve terminals. In this study, we investigated the number of GLU and...
The mesolimbic dopamine system of the brain, in particular the nucleus accumbens (Acb), is long known to be involved in reward behavior. When compared with the alcohol-nonpreferring NP rats, the alcohol-preferring P rats exhibit lower dopamine (DA) levels in the Acb as well as in other forebrain areas (20). In the present study, the DA innervation density, as determined by tyrosine hydroxylase (TH)...
