Astrocyte-specific transcriptome responses to chronic ethanol consumption
Ontology highlight
ABSTRACT: Purpose: Traditional whole-tissue sequencing approaches do not fully capture brain cell-type specific effects of chronic alcohol. Therefore, the purpose of this study was to identify the specific transcriptome alterations in astrocytes due to chronic alcohol. Methods: We performed RNA-sequencing on astrocytes isolated from the prefrontal cortex (PFC) of C57BL/6J mice following chronic every-other-day alcohol consumption. Results: Differential expression analysis revealed alcohol-induced gene expression changes unique to astrocytes that could not be identified using whole tissue homogenate analysis. Enrichment analysis revealed involvement of calcium-related signaling and regulation of extracellular matrix genes in the astrocyte response to alcohol abuse. Conclusion: Our study presents the first focused analysis on the astrocyte transcriptome following chronic alcohol consumption, provides a framework for studying the functional response of astrocytes to alcohol and the possible astrocyte-specific effects of alcohol. In addition, our data represents a novel resource for groups interested in biological functions of astrocytes in the adult mouse PFC.
