Studies using mice with beta4 nicotinic acetylcholine receptor (nAChR) subunit deficiency (beta4-/- mice) helped reveal the roles of this subunit in bradycardiac response to vagal stimulation, nicotine-induced seizure activity and anxiety. To identify genes that might be related to beta4-containing nAChRs activity, we compared the mRNA expression profiles of brains from beta4-/- and wild-type mice using Affymetrix U74Av2 microarray. Seventy-seven genes are significantly differentiated.
Microarray gene expression profiling results of rat-striatum after cocaine self-administration were used to identify co-regulation of certain mRNAs involved in cocaine-induced changes in circadian rhythmicity. This gene set comprises upregulated genes during the 7-day period of hourly cocaine self-infusion.

Striatum Gene Expression Correlates for ACTI05_ETHA measured in BXD RI Females obtained using GeneNetwork Striatum M430V2 (Apr05) RMA. The ACTI05_ETHA measures Distance traveled (cm) during the first five minutes after ethanol under the domain Ethanol. The correlates were thresholded at a p-value of less than 0.001.

F2 mice from a hybrid cross of C57BL/6J and FVB/NJ had heightened consumption of EtOH in 2 bottle, water versus ethanol, choice, with accending ethanol levels. Chromosome 11 had multiple suggestive markers, with LOD scores reflecting both additive and dominance variation taken together, as shown in Fig. 5.

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.

Chronic cocaine - Cocaine-paired (conditioned place preference) vs. Control (saline or cocaine-non-paired) DNA microarray All genes on microarray presented After the pre-conditioning phase where animals were allowed access to either compartment for 15 minutes for 4 consecutive days, the conditioning phase for the cocaine-paired groups and cocaine non-paired groups began, consisting of eight subsequent daily sessions. For both groups, cocaine (10 mg / kg) or saline injections were administered on alternate days. For the cocaine-paired groups, rats were immediately placed in one of the two compartments for 30 min with the door in place restricting a z transformation followed by z test and anova followed by Student-Newman-Keuls' post hoc test. Gene expression profile was assessed 24 h after the last conditioning session that corresponded to 48 h after last cocaine exposure, when drug has been eliminated from the body and transient transcriptional changes are likely to be minimal. Therefore, changes in gene expression at this time-point are likely to reflect longer lasting adaptations that may account for maintenance of cocaine-induced memories. The complete lists of normalized gene expression values for the hippocampus of saline-treated, cocaine non-paired and cocaine-paired groups are presented. Analyses revealed that 214 transcripts were differentially regulated in the hippocampus of cocaine-paired rats vs. non-paired and saline-treated controls. Cocaine-induced conditioned place preference caused significant increases in the expression of 151 genes and caused decreases in the expression of 63 genes. (NIF Table ID 130.1 [83])

The complete lists of normalized gene expression values for the frontal cortex of saline-treated, cocaine non-paired and cocaine-paired groups are presented. Differences in the expression of 39 transcripts in the frontal cortex were related to the conditioned place preference paradigm. These include increases in the level of 22 genes and decreases in 17 genes. (NIF Table ID 130.3 [83.5])

Acute nicotine - Nicotine vs. Saline DNA microarray Change in gene expression All the animals received a subcutaneous saline injection once daily for 5 days to habituate them to the injection process. On day 6, animals received a subcutaneous injection of saline or nicotine in saline (2 mg / kg). Animals were killed by cervical dislocation 1, 2, 4, or 6 h following saline or nicotine injection. S-score (significance score) algorithm Change in expression at 6 hours. S-scores (significance score) > / = 2 or < / = -2 consistently in two adjacent time-points from the 1-, 2-, 4- and 6-h time-points. For a comparison between two arrays, an S-score of 2 or ?2 corresponds to a P value of 0.046. (NIF Table ID 339 [192])

Chronic cocaine - Cocaine vs. Saline DNA microarray Change in gene expression Five rats were trained to self-administer cocaine infusions (1.5 mg / kg) during daily sessions. Once rats acquired cocaine self-administration (five consecutive sessions in which rats earned all 20 infusions that were available), cocaine infusions (1.5 mg / kg) were available in discrete 10-min trials 24-hr per day (4 trials / hr). Each discrete trial was initiated by the extension of the left lever into the chamber. Each response on this lever during a 10-minute discrete trial produced an infu Genespring 7.0 A gene was considered to be expressed if its signal intensity was a minimum of twice the background in at least four of the five replicates. Upregulated genes were defined as having an average expression ratio of >1.4, and the downregulated genes were defined as having an average expression ratio of <0.7. A gene was considered to be significantly regulated if the t-test p-value was < 0.05 with the false discovery rate (FDR) as the multiple testing correction. (NIF Method ID 182)
