Preference for 10% ethanol (g/kg) in tap water offered vs. tap water; means are the average of days 2 and 4 of a 4-day 24-hr access period by Phillips TJ , et al
Whole Brain Gene Expression Correlates for ACTI_DIFF_20 measured in BXD RI Females obtained using INIA Brain mRNA M430 (Jun06) RMA. The ACTI_DIFF_20 measures Difference in distance traveled (cm) during the first last min (saline-ethanol) under the domain Ethanol. 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.

Genes downregulated in livers of Eif2ak4(Gcn2)-mutant mice 30 minutes after perfusion with amino acids lacking methionine. Removing methionine induces amino-acid starvation. Sequences reported in the manuscript were used to search the MGI resource using the batch query form on June 15, 2018. Sequences that did not match were investigated manually. Sequences that were associated with putative assignments to gene identifiers were included. Values represent z-scores. Higher scores were used for genes represented more than once.
Peroxisome proliferator-activated receptors (PPARs) are nuclear hormone receptors that act as ligand-activated transcription factors. Although prescribed for dyslipidemia and type-II diabetes, PPAR agonists also possess anti-addictive characteristics. PPAR agonists decrease ethanol consumption and reduce withdrawal severity and susceptibility to stress-induced relapse in rodents. However, the cellular and molecular mechanisms facilitating these properties have yet to be investigated. We tested three PPAR agonists in a continuous access two-bottle choice (2BC) drinking paradigm and found that tesaglitazar (PPARα/γ; 1.5 mg/kg) and fenofibrate (PPARα; 150 mg/kg) decreased ethanol consumption in male C57BL/6J mice while bezafibrate (PPARα/γ/β; 75 mg/kg) did not. We hypothesized that changes in brain gene expression following fenofibrate and tesaglitazar treatment lead to reduced ethanol drinking. We studied unbiased genomic profiles in areas of the brain known to be important for ethanol dependence, the prefrontal cortex (PFC) and amygdala, and also profiled gene expression in liver. Genomic profiles from the non-effective bezafibrate treatment were used to filter out genes not associated with ethanol consumption. Because PPAR agonists are anti-inflammatory, they would be expected to target microglia and astrocytes. Surprisingly, PPAR agonists produced a strong neuronal signature in mouse brain, and fenofibrate and tesaglitazar (but not bezafibrate) targeted a subset of GABAergic interneurons in the amygdala. Weighted gene co-expression network analysis (WGCNA) revealed co-expression of treatment-significant genes. Functional annotation of these gene networks suggested that PPAR agonists might act via neuropeptide and dopaminergic signaling pathways in the amygdala. Our results reveal gene targets through which PPAR agonists can affect alcohol consumption behavior.
