Cocaine exposure to escalation of cocaine intake and glutamatergic gene expression
Description:
Here, we investigated the contribution of behavioral contingency of cocaine administration on escalation of cocaine intake and gene expression in the dorsal medial prefrontal cortex (dmPFC) in adult male rats. Rats were allowed to self-administer intravenous cocaine (0.25 mg/infusion) under either limited cocaine-(1 h/day), prolonged cocaine-(6 h/day), or limited cocaine-(1 h/day) plus yoked cocaine-access (5 h/day); a control group received access to saline (1 h/day). One day after the final self-administration session, the rats were euthanized and the dmPFC was removed for quantification of mRNA expression of critical glutamatergic signaling genes, Homer2, Grin1, and Dlg4, as these genes and brain region have been previously implicated in addiction, learning, and memory. All groups with cocaine-access showed escalated cocaine intake during the first 10 min of each daily session, and within the first 1 h of cocaine administration. Additionally, the limited-access + yoked group exhibited more non-reinforced lever responses during self-administration sessions than the other groups tested. Lastly, Homer2, Grin1, and Dlg4 mRNA were impacted by both duration and mode of cocaine exposure. Only prolonged-access rats exhibited increases in mRNA expression for Homer2, Grin1, and Dlg4 mRNA.Â

Affymetrix oligonucleotide arrays to assess gene expression in brains of mice selectively bred for differences in acute functional tolerance to an incoordinating effect of ethanol (HAFT mice, high acute functional tolerance; LAFT mice, low acute functional tolerance)
Striatum Gene Expression Correlates for CONSTRICT measured in BXD RI Females & Males obtained using GeneNetwork Striatum M430V2 (Apr05) RMA. The CONSTRICT measures Morphine Response Severity of abdominal constriction under the domain Morphine. The correlates were thresholded at a p-value of less than 0.001.

A list of genes whose transcript abundance in the PFC changed significantly 4 hours after an acute dose of ethanol (1.8 g/kg). This list was generated using Fisher's Combined Probability test to analyze saline vs ethanol S-scores across B6 and D2 inbred strains (n=3) and 27 BXD RI lines (n=1). Statistical significance was determined using 1,000 permutations of S-score data and selecting for probe-sets with q-values < 0.05. Aaron Wolen 5-26-10.

Analyzed the gene expression profile of a homogeneous population of duodenal epithelial cells taken from patients with active celiac disease, in comparison to control patients. Of the 3,800 genes present on the array (all of which have been previously annotated), 3549 had sufficient data across the five experiments for comparison. Many of these genes showed fold-change ratios with little or no deviation from 1. Thus, to focus on only differentially expressed genes, the list was filtered on a fo
