Gene in Ethanol Study Datasets
Gene Information
Original ID1:Oprk1
Fold Change:-1.2
P Value:0.007
Note:Differential expression between ethanol and saccharin groups in nucleus accumbens
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.
