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:The objective of this study was to determine changes in gene expression within the extended amygdala following binge-like alcohol drinking by adolescent alcohol-preferring (P) rats. Starting at 28 days of age, P rats were given concurrent access to 15 and 30 % ethanol for 3 one-h sessions for 5 consecutive days each week until they were 49 days old. Rats were killed by decapitation 3 h after the first ethanol access session on the 15th day of drinking. RNA was prepared from micropunch samples of the nucleus accumbens shell (Acb-sh) and central nucleus of the amygdala (CeA). Ethanol intakes were 2.5 to 3.0 g/kg/session. There were 154 and 182 unique named genes that significantly differed (FDR = 0.2) between the water and ethanol group in the Acb-sh and CeA, respectively. Gene Ontology (GO) analyses indicated that adolescent binge drinking produced changes in the in biological processes involved in cell proliferation and regulation of cellular structure in the Acb-sh, and in neuron projection and positive regulation of cellular organization in the CeA. Ingenuity Pathway Analysis indicated that, in the Acb-sh, there were several major intracellular signaling pathways (e.g., cAMP-mediated and protein kinase A signaling pathways) altered by adolescent drinking, with 3-fold more genes up-regulated than down-regulated in the alcohol group. The cAMP-mediated signaling system was also up-regulated in the CeA of the alcohol group. Weighted gene co-expression network analysis (WGCNA) indicated significant G-protein coupled receptor signaling and transmembrane receptor protein kinase signaling categories in the Acb-sh and CeA, respectively. Overall, the results of this study indicated that binge-like alcohol drinking by adolescent P rats is differentially altering the expression of genes in the Acb-sh and CeA, some of which are involved in intracellular signaling pathways and may produce long-term changes in neuronal function. Differences in gene expression in the central nucleus of the amygdala (CeA) were compared in two groups of alcohol-preferring (P) rats, one given water only and the other given access to 15 & 30% ethanol during adolescence.

Project description:The objective of this study was to determine common innate differences in gene expression in the ventral tegmental area (VTA) among the selectively bred (a) alcohol-preferring (P) vs. alcohol-non-preferring (NP) rats: (b) high-alcohol-drinking (HAD) vs. low-alcohol-drinking (LAD) rats (both replicates); (c) ALKO alcohol (AA) vs. nonalcohol (ANA) rats; and (d) Sardinian alcohol-preferring (sP) vs. alcohol-nonpreferring (sNP) rats. There were between 350 and 1400 unique named genes that were significantly different between the individual line-pairs. Gene Ontology (GO) and Ingenuity Pathways analyses indicated significant categories and networks in common for up to 3 line-pairs, but not for all 5 line-pairs; there were few genes in common between any of the line-pairs in these categories and networks. The overall ANOVAs of the combined data for the 5 line-pairs indicated over 1300 significant differences in expression of named genes. Ingenuity analysis revealed (a) several significant networks with clusters of genes associated with App, Egfr, Ccnd1, Itga2b, Rxra and Vcl; and (b) changes in genes within networks associated with dopamine, the glutamate synapse, Nfkb signaling, IL pathways and integrin. There were 22 genes that were significantly different in the overall ANOVA and were significantly different (in the direction) in at least 3 line-pairs, e.g., Crebl2, Gsta4, Itga9 & Itg2. In conclusion, the findings suggest that (a) different innate mechanisms may be contributing to vulnerability to high alcohol drinking behavior among the selectively bred lines, and (b) small contributions in expression of multiple genes within certain transmitter systems and intracellular signaling pathways may contribute to the disparate alcohol drinking characteristics of the 5 line-pairs.
