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.

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])

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 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])
