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:The objective of this study was to determine changes in gene expression in the ventral tegmental area (VTA) following loss-of-control alcohol drinking by alcohol-preferring (P) rats. Adult female P rats (n = 7) were given concurrent access to 10, 20 and 30% EtOH for four 1-hr sessions daily for 10 weeks followed by 2 cycles of 2 weeks of abstinence and 2 weeks of EtOH access. Rats were killed by decapitation 3 hr after the 4th daily EtOH-access session at the end of the second 2-week relapse period. An age-matched water control group of female P rats (n = 8) was also killed. RNA was prepared from micropunch samples of the VTA from individual rats; analyses were conducted with Affymetrix Rat 230.2 chips. Ethanol intakes were 1.5-2.5 g/kg per sessions, resulting in blood levels >200 mg% at the end of the 4th session. There were 211 named genes that were significantly different (FDR = 0.1) between the water and EtOH groups. Bioinformatics analyses indicated alterations in (a) transcription factors that reduced excitation-coupled transcription and promoted exocitotic neuronal damage involving clusters of genes associated with Nfkbia, Fos and Srebf1; (b) genes that reduced cholesterol and fatty acid synthesis, and increased protein degradation; and (c) genes involved in cell-to-cell interactions and regulation of the actin cytoskeleton. Among the named genes, there were 62 genes in common with differences between alcohol-naïve P and non-preferring (NP) rats, with 43 of the genes changing in the opposite direction following excessive binge-like drinking. These genes are involved in a pro-inflammatory response, and enhanced response to glucocorticoids and steroid hormones. Overall, the results of this study indicated that excessive binge-like alcohol drinking by P rats may be altering the expression of genes that promote neuronal damage.

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: The goal of this study to examine mRNA transcriptomic changes in reward-related brain regions of subjects with alcohol use disorder. Methods: Total RNAs were extracted from postmortem ventral tegmental area of 12 AUD and 12 control subjects. rRNA depletion RNA sequencing was performed and the sequence reads were processed using the bulk RNA-seq processing pipeline Pipeliner workflow (Federico et al. Front Genet 2019; 10, 614). AUD-associated mRNA transcriptomic changes were analyzed by the Limma-Voom method. Results: Differentially expressed mRNAs (absolute FC>2.0 & P<0.05) were identified in postmortem ventral tegmental area of subjects with alcohol use disorder (AUD). Chronic alcohol consumption may alter mRNA transcriptome profiles in reward-related brain regions, resulting in alcohol-induced neuroadaptations.

Project description:Drugs of abuse including nicotine and alcohol elicit their effect by stimulating the mesocorticolimbic dopaminergic system. There is a high incidence of nicotine dependence in alcoholics. To date only limited data is available on the molecular mechanism underlying the action of alcohol and nicotine in the human brain. This study utilised gene expression screening to identify genes sensitive to chronic alcohol abuse within the ventral tegmental area of the human brain.
