We have previously shown that ethanol-exposed astrocytes alter neuronal neurite outgrowth in an <jats:italic>in vitro<\/jats:italic> co-culture system and that ethanol alters the astrocyte-produced extracellular matrix (ECM) <jats:italic>in vitro<\/jats:italic>, with similar alterations <jats:italic>in vivo<\/jats:italic>. In this study, we utilized the translating ribosome affinity purification (TRAP) procedure in <jats:italic>Aldh1l1<\/jats:italic>-EGFP\/Rpl10a transgenic mouse primary cortical astrocyte cultures to transcriptionally and translationally profile the astrocyte response to ethanol. We found a large number of differences between the total RNA pool and the translating RNA pool, indicating that the transcriptional state of astrocytes may not always reflect the translational state of astrocytes. In addition, there was a considerable overlap between ethanol-dysregulated genes in the total RNA pool and the translating RNA pool. Comparisons to published datasets indicate the <jats:italic>in vitro<\/jats:italic> model used here is most similar to PD1 or PD7 <jats:italic>in vivo<\/jats:italic> cortical astrocytes, and the ethanol-regulated genes showed a significant overlap with models of chronic ethanol exposure in astrocytes, a model of third-trimester ethanol exposure in the hippocampus and cerebellum, and an acute model of ethanol exposure in the hippocampus. These findings will further our understanding of the effects of ethanol on astrocyte gene expression and protein translation and how these changes may alter brain development and support the use of <jats:italic>in vitro<\/jats:italic> astrocyte cultures as models of neonatal astrocytes.<\/jats:p>","DOI":"10.3389\/fnins.2023.1193304","type":"journal-article","created":{"date-parts":[[2023,6,21]],"date-time":"2023-06-21T08:01:47Z","timestamp":1687334507000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Ethanol-induced transcriptional and translational changes in Aldh1l1-Egfp\/Rpl10a cortical astrocyte cultures"],"prefix":"10.3389","volume":"17","author":[{"given":"Joel G.","family":"Hashimoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaolu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Guizzetti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,6,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"41","DOI":"10.1038\/nrn1824","article-title":"Astrocyte\u2013endothelial interactions at the blood\u2013brain barrier","volume":"7","author":"Abbott","year":"2006","journal-title":"Nat.
