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.

Project description:Sardinian alcohol-preferring (sP) and Sardinina alcohol-non preferring (sNP) rats have been selectively bred for opposite alcohol preference and consumption. The project proposed to identify salivary markers distinguishing the two rat lines possibly correlated to alcohol preference, by a proteomic approach.

Project description:Purpose: Genetic factors significantly affect alcohol consumption and vulnerability to withdrawal. Some genetic models that show predisposition to severe withdrawal are also predisposed to low ethanol consumption and vice versa, even when tested independently in naïve animals. The study was undertaken to understand gene and network differences between mice selectively bred for high withdrawal/low withdrawal or low withdrawal/high consumption. Methods: Beginning with a C57BL/6J×DBA/2J F2 intercross founder population, animals were simultaneously selectively bred for both high alcohol consumption and low acute withdrawal (SOT line), or vice versa (NOT line). Using randomly chosen fourth selected generation (S4) mice (N= 18-22/sex/line), RNA-Seq was employed to assess genome-wide gene expression in the ventral striatum. The Mega-MUGA array was used to detect genome-wide genotypic differences. Differential gene expression and the weighted gene co-expression network analysis (WGCNA) were implemented. Results: The new selection of the SOT and NOT lines was similar to that reported previously (Metten et al. 2014). One thousand eight hundred and fifteen transcripts were detected as being differentially expressed between the lines. For the genes overexpressed in the SOT line there was enrichment in genes associated with cell adhesion, synapse organization and post-synaptic membrane. The genes with a cell adhesion annotation included 23 protocadherins, Mpdz & Dlg2. Genes with a postsynaptic membrane annotation included Gabrb3, Gphn, Grid1, Grin2b, Grin2c & Grm3. The genes overexpressed in the NOT line were enriched in a network module (red) with annotations associated with mitochondrial function. Several of these genes were module hub nodes and these included Nedd8, Guk1, Elof1, Ndufa8, & Atp6v1f. Conclusions: Marked effects of selection on gene expression were detected. The NOT line was characterized by the increased expression of hub nodes associated with mitochondrial function. Genes overexpressed in the SOT aligned with previous findings e.g. Colville et al. (2017) that high ethanol preference and consumption is associated with effects on cell adhesion and glutamate synaptic plasticity.
