Transcriptomic responses to acute or chronic ethanol exposure observed across five brain regions in male mice

ABSTRACT: Alcohol use disorder (AUD) has been consistently linked to transcriptomic dysregulation in the brain. Alcohol itself produces transcriptomic changes in the brain, and resulting molecular changes may contribute to the progression or maintenance of AUD. However, little is known about how ethanol-induced transcriptomic outcomes differ between acute and chronic exposure. Here, we systematically investigated the transcriptomic effects of ethanol exposure across key brain regions relevant to AUD and how these outcomes differ between acute and chronic exposure. To this end, RNA sequencing was done for the cortex, dorsal hippocampus, ventral hippocampus, dorsal striatum, and ventral striatum of adult male mice that were given a daily i.p. dose of ethanol or saline for 1 day (acute) or 10 days (chronic). Both ethanol exposure paradigms resulted in dysregulated expression (gene and transcript) and splicing in the investigated brain regions. Transcriptomic dysregulation varied across regions and was more robust following acute than chronic ethanol exposure. Paradigm-dependent transcriptional effects of ethanol were limited in most regions but were striking in the ventral hippocampus, suggesting alcohol's transcriptomic effects in this region might play a relevant role in the transition from limited to chronic alcohol consumption. Overall, this systematic study illuminates alcohol's effects on transcriptional regulation in the brain and how these effects differ across brain regions and by extent of exposure, ultimately providing valuable insight for developing novel therapeutics for AUD.

Brain Proteomic Atlas of Alcohol Use Disorder in Adult Males

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).

Profiling of mRNA transcriptomic changes using RNA-seq in postmortem ventral tegmental area (VTA) of subjects with alcohol use disorder

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 ventral tegmental area 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 ventral tegmental area 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.

Polygenic Risk for Alcohol Use Disorder Affects Cellular Responses to Ethanol Exposure in a Human Microglial Cell Model II

Project description:Polygenic risk scores (PRS) assess genetic susceptibility to Alcohol Use Disorder (AUD), yet their molecular implications remain underexplored. Neuroimmune interactions, particularly in microglia, are recognized as significant contributors to AUD pathophysiology. We investigated the interplay between AUD PRS and ethanol in human microglia derived from iPSCs from individuals with high-or low-PRS (HPRS or LPRS) of AUD. Ethanol exposure induced elevated CD68 expression and morphological changes in microglia, with differential responses between HPRS and LPRS microglial cells. Transcriptomic analysis revealed expression differences in MHCII complex and phagocytosis-related genes following ethanol exposure; HPRS microglial cells displayed enhanced phagocytosis and increased CLEC7Aexpression, unlike LPRS microglial cells. Synapse numbers in co-cultures of induced neurons with microglia after alcohol exposure were lower in HRPS co-cultures, suggesting possible excess synapse pruning. This study provides insights into the intricate relationship between AUD PRS, ethanol, and microglial function, potentially influencing neuronal functions in developing AUD.
