Project description:Persistent changes in brain gene expression are hypothesized to underlie thealtered neural signaling producing abusive consumption in AUD. To identify brain regional gene expression networks contributing to progressive ethanol consumption, we performed microarray and scale-free network analysis of expression responses in a C57BL/6J mouse model utilizing chronic intermittent ethanol by vapor chamber (CIE) in combination with limited access oral ethanol consumption. The interaction of CIE and oral consumption was studied with Affymetrix microarrays. Gene expression was studied in medial prefrontal cortex, nucleus accumbens, hippocampus, bed nucleus of the stria terminalis, and central nucleus of the amygdala. Brain region expression networks were analyzed for ethanol-responsive gene expression, correlation with ethanol consumption and functional content using extensive bioinformatics studies.

Project description:Rats were trained to orally self-administer alcohol in a concurrent, two-lever, free-choice contingency using a modification of the sweet solution fading procedure (O'Dell et al., 2004; Roberts et al., 2000; Vendruscolo et al., 2012). Following acquisition of self-administration, rats were allowed to self-administer unsweetened alcohol (10%) for 4 weeks and were then assigned to two groups matched by levels of responding: one group (dependent group) was exposed to chronic, intermittent ethanol vapors for 4 weeks to induce dependence; the other group (nondependent group) was not exposed to ethanol vapor. After a month of vapor exposure, rats were again tested during acute withdrawal (6-8 hours after removal from the vapor chambers) until stable levels of alcohol intake were achieved. As expected, alcohol vapor-exposed rats self-administered significantly greater amounts of alcohol than control rats not exposed to alcohol vapor during acute withdrawal. Rats were sacrificed during protracted abstinence (3 weeks after the end of alcohol vapor exposure) along with age-matched alcohol naive rats. 96 gene expression profiles (GEP) were obtained from 8 brain regions believed to be relevant in alcoholM-bM-^@M-^Ys reinforcing properties using the Affymetrix RN230.2 platform. Specifically, the following brain regions were microdissected and analyzed from nondependent and dependent alcohol self-administering rats as well as age-matched alcohol naive rats: (a) medial prefrontal cortex (MPF), (b) shell and (c) core NAc sub-regions, (d) central nucleus (CeA) and (e) basolateral nucleus of the amygdala (BLA), (f) dorsolateral and (g) ventral bed nucleus of the stria terminalis (BNST), and (h) ventral tegmental area (VTA).

Project description:To identify distinct transcriptional patterns between the major subcortical dopamine targets commonly studied in addiction we studied differences in gene expression between the bed nucleus of the stria terminalis (BNST), nucleus accumbens (NAc), and dorsal striatum (dStr) using microarray analysis. We first tested for differences in expression of genes encoding transcripts for common neurotransmitter systems as well as calcium binding proteins routinely used in neuroanatomical delineation of brain regions. This a priori method revealed differential expression of corticotropin releasing hormone (Crh), the GABA transporter (Slc6a1), and prodynorphin (Pdyn) mRNAs as well as several others between. Using a Gene ontology tool, functional scoring analysis, and Ingenuity Pathway Analysis, we further identified several physiological pathways that were distinct among these brain regions. These two different analysis both identified calcium signaling, G-coupled protein receptor signaling, and adenylate cyclase-related signaling as significantly different among the BNST, NAc, and dStr. The results support other studies suggesting that crucial pathways involved in neurotransmission are distinct among the BNST, NAc, and dStr, and provide insight into the potential use of pharmacological agents that may target region-specific signaling pathways. Further, these studies provide a framework for future mouse-mouse comparisons of transcriptional profiles after behavioral/pharmacological manipulation. Genome-wide microarray was used to detect gene expression. Global functional profile, transcritional networks and canonical pathways were illustrated from the gene expression patterns. Experiment Overall Design: The genome-wide gene expression of mouse brain region bed nucleus of the stria terminalis, nucleus accumbens, and dorsal striatum were analyzed by Affymetrix Mouse430_2 chip. The expression and functional profiles were compared between these 3 tissues and cross-validated from independant data published before.

Project description:Alcohol Use Disorder (AUD) is a complex psychiatric disorder with strong genetic as well as environmental risk factors. One risk factor for developing AUD is binge drinking. High Drinking in the Dark mice (HDID-1) have been selectively bred from genetically heterogeneous mice (HS/Npt stock) for attaining high blood alcohol concentrations (BAC) after a 4-hour drinking session in which a single bottle containing 20% ethanol is available and serve as a genetic model of binge drinking. To discover molecular mechanisms underlying the genetic predisposition to binge drinking, we characterized global gene expression in 7 brain regions across the addiction neurocircuit, precisely excised using laser capture microdissection from male, ethanol-naive HDID-1 and control mice Brain regions included in the analysis are prefrontal cortex (PFC), nucleus accumbens core (AcbC), nucleus accumbens shell (AcbSh), bed nucleus of the stria terminalis (BNST), basolateral amygdala (BLA), central amygdala (CeA), and ventral tegmental area (VTA)

Project description:We examined global gene expression profiles in amygdala (AMY), nucleus accumbens (NAC), prefrontal cortex (PFC) and Liver of male C57BL/6J mice exposed to 4 cycles of chronic intermittent ethanol (CIE) vapor. Animals were sacrificed at 0, 8, and 120 hr following the last ethanol exposure. Mice were exposed to 4 cycles of intermittent vapor [4 days of 16 hours vapor/ 8 hours air] with a week between each cycle. Before entry into the vapor chambers, animals were injected with pyrazole (1 mMol/kg) and either ethanol (1.6 g/kg) or saline (controls). Animals were sacrificed at 0, 8, and 120 hr following the last ethanol exposure. The liver 0 hr control group contained 7 animals. Otherwise there were 8 animals per group (treated, control) at each time point.
