Using RNA-Seq we quantified mRNA transcripts in postmortem total hippocampus from alcoholics, cocaine addicts and controls and also from alcohol-na ̈ıve, alcohol preferring (P) and non-preferring (NP) rats selectively bred for extremes of alcohol-seeking behavior that also show a general addictive tendency. A pathway-targeted analysis of 25 GABAergic genes encoding proteins implicated in GABA synthesis, metabolism, synaptic transmission and re-uptake was undertaken. Statistics presented as FDR corrected P-values.

QTL associated with pentobarbital withdrawal QTL 3. This interval was obtained by using a fixed interval width of 25 Mbp around the peak marker (25961780)
Cerebellum differential expression analysis of genotype by time effects in Pax6 mice and controls. This set contains genes for which there is an additive effect of the mutation and linear increase in both mutant and wild types through time.
Activation of the mesolimbic dopamine reward pathway by acute ethanol produces reinforcement and changes in gene expression that appear to be crucial to the molecular basis for adaptive behaviors and addiction. The inbred mouse strains DBA/2J and C57BL/6J exhibit contrasting acute behavioral responses to ethanol. We used oligonucleotide microarrays and bioinformatics methods to characterize patterns of gene expression in three brain regions of the mesolimbic reward pathway of these strains. Expression profiling included examination of both differences in gene expression 4 h after saline injection or acute ethanol (2 g/kg). Using a rigorous stepwise method for microarray analysis, we identified 788 genes differentially expressed in control DBA/2J versus C57BL/6J mice and 307 ethanol-regulated genes in the nucleus accumbens, prefrontal cortex, and ventral tegmental area. There were strikingly divergent patterns of ethanol-responsive gene expression in the two strains. Ethanol-responsive genes also showed clustering at discrete chromosomal regions, suggesting local chromatin effects in regulation. Ethanol-regulated genes were generally related to neuroplasticity, but regulation of discrete functional groups and pathways was brain region specific: glucocorticoid signaling, neurogenesis, and myelination in the prefrontal cortex; neuropeptide signaling and developmental genes, including factor Bdnf, in the nucleus accumbens; and retinoic acid signaling in the ventral tegmental area. Bioinformatics analysis identified several potential candidate genes for quantitative trait loci linked to ethanol behaviors, further supporting a role for expression profiling in identifying genes for complex traits. Brain region-specific changes in signaling and neuronal plasticity may be critical components in development of lasting ethanol behavioral phenotypes such as dependence, sensitization, and craving.
Gene expression changes in the post-mortem nucleus accumbens of chronic heroin abusers. Overall, little overlap in gene expression profiles was seen between the two drug-abusing cohorts: out of the approximately 39,000 transcripts investigated, the abundance of only 25 was significantly changed in both cocaine and heroin abusers, with nearly one-half of these being altered in opposite directions. 1050 Transcripts had different in abundance between the majority of heroin subjects and their matched controls.
Study analyzed 812 differentially expressed gene candidates from peripheral blood mononuclear cells (PBMC) from morphine and saline treated rats, and suggests similarities between the gene expression profile in PBMCs and in the brain of morphine-treated rats. This set contains the 79 genes implicated by this study to modulate expression during chronic morphine treatment.

Heterozygote mice from a hybrid cross of C57BL/6J and FVB/NJ had heightened EtOH consumption, preference or blood EtOH concentration compared to either homozygous groups. The magnitude of dominant deviation on Chr. 11, as noted in Fig. 9, was measured after a drinking in the dark paradigm, 24hr two-bottle-choice and subsequent blood ethanol concentration measurement.
