The nuclear accumbens (NA) and amygdale (Amyg) of inbred alcohol-preferring mice were examined for differential gene expression and it findings suggest that changes in gene expression in the ACB of iP rats are associated with the reinforcing effects of ethanol (EtOH). This gene set comprises 201 genes that were significantly expressed in the NA during the experiment.
Drug Naïve DO mice were tested for open field, light dark, hole board, novelty place preference before collecting the striatum. RNA-Seq data was analyzed with paraclique using a bicor was used with a correlation coefficient threshold of |0.5| (unsigned), minimum seed clique size of 5, minimum finished paraclique size of 10, proportional glom factor of 0.2 for paraclique construction.
The current study used two inbred mouse strains, C57BL/6 J and A/J, to investigate the genetics of behavioral responses to fentanyl. Mice were tested for conditioned place preference and fentanyl-induced locomotor activity. C57BL/6J mice formed a conditioned place preference to fentanyl injections and fentanyl increased their activity. Neither effect was noted in A/J mice. We conducted RNA-sequencing on the nucleus accumbens of mice used for fentanyl-induced locomotor activity. Surprisingly, we noted few differentially expressed genes using treatment as the main factor. However many genes differed between strains.

This gene set comprises 137 genes that were significantly expressed in the NA during the experiment. Background: The nuclear accumbens (NA) and amygdale (Amyg) of inbred alcohol-preferring mice were examined for differential gene expression and it findings suggest that changes in gene expression in the ACB of iP rats are associated with the reinforcing effects of ethanol (EtOH).
Hippocampus Gene Expression Correlates for OF_DIST_0_5 measured in BXD RI Males obtained using GeneNetwork Hippocampus Consortium M430v2 (Jun06) RMA. The OF_DIST_0_5 measures Open Field - Total distance traveled 0-5 minutes under the domain Basal Behavior. The correlates were thresholded at a p-value of less than 0.001.

alcohol preference 7 spans 13.47 - 63.47 Mbp (NCBI Build 37) on Chr7. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org).

QTL for ethanol conditioned taste aversion on Chr7 at D7Ncvs57 (73.76 Mbp , Build 37)
Description:
ethanol conditioned taste aversion spans 48.76 - 98.76 Mbp (NCBI Build 37) on Chr7. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org).
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])

None - Basal gene expression profiles between C57BL/6J, DBA/2J, 129P3/J, and SWR/J strains DNA microarray Change in gene expression Two-way analysis of variance (ANOVA). 3,457 probe sets (corresponded to 2,870 different transcripts) with significant inter-strain differences (differ by at least 1.2-fold) - False discovery rate [FDR] < 1%, , rank > 3. Such a large disparity in the mouse striatal transcriptome was estimated by comparing nine array replicates prepared per strain from all of the treatment groups. More than half of the identified probe sets exhibited markedly significant results (1,735 with rank > 7). (NIF Method ID 84.1)
