| | Dataset Information | | Name: | | 17451403 | | Method: | | Microarray and QTL | | Tissue: | | Nucleus accumbens, frontal cortex, amygdala, hippocampus, and striatum | | Phenotype: | | Alcohol Preference, alcohol-preferring, alcohol-nonpreferring | | Publication: | | Carr et al. Alcohol Clin Exp Res. (2007) Identification of candidate genes for alcohol preference by expression profiling of congenic rat strains. PubMed | | Summary: | | A highly significant quantitative trait locus (QTL) on chromosome 4 that influenced alcohol preference was identified by analyzing crosses between the iP (inbred alcohol-preferring) and iNP (inbred alcohol-nonpreferring) rats. Congenic strains in which the iP chromosome 4 QTL interval was transferred to the iNP (NP.P) exhibited the expected increase in alcohol consumption compared with the iNP background strain. Analyses within individual brain regions that focused on genes within the QTL interval detected differential expression in all 5 brain regions; a total of 35 genes were detected in at least 1 region, ranging from 6 genes in the nucleus accumbens to 22 in the frontal cortex. |

| | Dataset Information | | Name: | | 18405950 | | Method: | | Microarray | | Tissue: | | Nucleus accumbens and amygdala | | Phenotype: | | Ethanol self-administration, alcohol-preferring | | Publication: | | Rodd et al. Pharmacol Biochem Behav. (2008) Differential gene expression in the nucleus accumbens with ethanol self-administration in inbred alcohol-preferring rats. PubMed | | Summary: | | The current study examined the effects of operant ethanol (EtOH) self-administration on gene expression kin the nucleus accumbens (ACB) and amygdala (AMYG) of inbred alcohol-preferring (iP) rats. Rats self-trained on a standard two-lever operant paradigm to administer either water-water, EtOH (15% v/v)-water, or saccharin (SAC; 0.0125% g/v)-water. For the ACB, there were 513 significant differences at the p < 0.01 level in named genes: 55 between SAC and water; 215 between EtOH and water, and 243 between EtOH and SAC. In the case of the AMYG (p < 0.01), there were 48 between SAC and water, 23 between EtOH and water, and 63 between EtOH and SAC group. |
