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.
By analyzing Genome-Wide Association data of successful vs. unsuccessful nicotine-abstinent participants in independent clinical trials from 3 centers, study replicates quit-success genes. To conduct the study, three cohorts were used. Sample 1 consisting of subjects who received a double-blinded placebo-controlled trial of bupropion hydrochloride and a trial of NRT. Sample 2 consisted of subjects who were used in the trial of the clinical effectiveness of NRT. Sample 3 consisted of subjects who were used in the trial of the clinical effectiveness of bupropion hydrochloride.

QTL for differences in cocaine responsiveness on Chr8 at D8MIt8 (53.66 Mbp , Build 37)
Description:
differences in cocaine responsiveness spans 28.66 - 78.66 Mbp (NCBI Build 37) on Chr8. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org).

Description:
METH responses for body temperature spans 70.66 - 120.66 Mbp (NCBI Build 37) on Chr8. 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])

Acute cocaine - A-FOS mouse vs. Littermate control
Description:
Acute cocaine - A-FOS mouse vs. Littermate control DNA microarray Change in gene expression Animals received a single injection of cocaine (30 mg / kg intraperitoneal) and the striatum harvested at 24 hours. Avadis Microarray analysis software; standard unpaired T-test. A p < 0.001 was used as a cutoff for the selection of genes. Genes are considered up or down regulated if their expression changed 1.4 fold relative to basal conditions. (NIF Table ID 334 [184])

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])

Chronic ethanol - Ethanol vs. Control DNA microarray Change in gene expression - Class II Alcoholics were classified based on the quantity of alcohol consumed, according to the National Health and Medical Research Council (NHMRC) (>80 g of alcohol per day), instead of the criteria established by the American Psychiatric Association (DSM-IV) or the World Health Organization (ICD-10). Many alcoholic patients in this study consumed significantly more than 80 g / day for most of their adult life. Cerebral atrophy was observed in three alcoholic cases. All alcoholic cases included in our Axon GenePix 4.0 software; partial least squares (PLS) statistical procedure; linear discriminant analysis (LDA) procedure for prediction analysis. PLS and LDA analysis were performed using in JMP IN software; principal component analysis (PCA) used STATISTICA software. Results reflect the combined dataset: Class I genes were qualitatively different, that is, they were predominantly detected in one group but not the other. They represent those that were more likely turned off or turned on as a result of alcohol abuse. Class II genes were consistently detected in both groups. They represent consistently expressed genes for which quantitative differences in expression could be determined. (NIF Method ID 157)
