Project description:Noncoding SNP variants in KCNJ6 have been linked with increased risk of alcohol use disorder (AUD) and the endophenotype EEG frontal theta event related oscillation (ERO) power. We prepared iPSC from subjects with contrasting diagnosis of AUD and KCNJ6 variants (AF, affected) or unaffected with reference KCNJ6 (UN). Induced neurons cultures were prepared from each iPSC line and harvested for RNAseq analysis. In these bulk RNAseq analyses, we do not identify meaningful differences by KCNJ6 haplotype, we we can validate expression of the long (18kb) 3'UTR from the KCNJ6 gene, and identify several additional SNPs linked with the original three. Additional studies used single cell RNAseq to isolate differentiated neurons from iN cultures and analysis of these samples found differences in neuron process formation and synaptic function, which were validated with morphometrics, immunocytochemistry, and electrophysiology.

Project description:Excessive alcohol consumption is a leading cause of preventable death worldwide. Neurobiological mechanisms associated with alcohol use disorder (AUD) remain insufficiently understood. Here, we provide RNA-sequencing data generated in nucleus accumbent and dorsolateral prefrontal cortex, from 114 deceased individuals: 58 AUD cases, 56 non-AUD controls. DNA methylation data on many of these same individuals is available (see GEO accession number GSE252501).

Project description:Alcohol use disorder (AUD) is a life-threatening disease characterized by compulsive drinking, cognitive deficits, and social impairment that continue despite negative consequences, which are driven by dysfunction of cortical areas, such as the orbitofrontal cortex (OFC), that normally balances decisions related to reward and risk. In this study, proteomics and machine learning analysis of post-mortem OFC brain samples collected from individuals with AUD revealed dysregulation of presynaptic (e.g., AP2A1) and mitochondrial proteins that predicted the occurrence and severity of AUD. Alcohol-sensitive OFC proteins also mapped to abnormal social behaviors and interactions. Validation using reverse genetics, we found that prefrontal Ap2a1 regulates alcohol drinking in genetically diverse mouse strains. Furthermore, we demonstrated sexual dimorphism in human OFC proteins that regulate extracellular matrix structure and signaling. Together, these findings highlight the impact of excessive alcohol consumption on the human OFC proteome and identify important cross-species cortical mechanisms underlying AUD.

Project description:The present study utilized patient-derived “cell-line” model systems treated with anti-craving drugs that are used to treat alcohol use disorder (AUD) as “molecular probes” to help identify molecular mechanisms associated with craving and AUD treatment outcomes.

Project description:Alcohol use disorder (AUD) affects transcriptomic, epigenetic and proteomic expression in several organs including the brain. Multi-omic analyses of the brain from individuals with AUD to date lack a comprehensive analysis of protein alterations in the multiple brain regions that underlie neuroadaptations occurring in AUD. We performed quantitative proteomic analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of human post-mortem tissue from brain regions that play a key role in the development and maintenance of AUD: amygdala (AMG), hippocampus (HIPP), hypothalamus (HYP), nucleus accumbens (NAc), prefrontal cortex (PFC) and ventral tegmental area (VTA). Brain tissues analyzed were from individuals with AUD (n = 11) and matched controls (n = 16).

Project description:Purpose: The goal of this study to examine mRNA transcriptomic changes in reward-related brain regions of subjects with alcohol use disorder. Methods: Total RNAs were extracted from postmortem putamen of 12 AUD and 12 control subjects. rRNA depletion RNA sequencing was performed and the sequence reads were processed using the bulk RNA-seq processing pipeline Pipeliner workflow (Federico et al. Front Genet 2019; 10, 614). AUD-associated mRNA transcriptomic changes were analyzed by the Limma-Voom method. Results: Differentially expressed mRNAs (absolute FC>2.0 & P<0.05) were identified in postmortem putamen of subjects with alcohol use disorder (AUD). Chronic alcohol consumption may alter mRNA transcriptome profiles in reward-related brain regions, resulting in alcohol-induced neuroadaptations.
