Gestational binge alcohol-induced alterations in maternal uterine artery transcriptome. Academic Article uri icon


  • Binge alcohol exposure during pregnancy results in diminished vessel function and altered proteome in the maternal uterine artery. We aimed to utilize high throughput RNA-seq deep-sequencing to characterize specific effects of binge alcohol exposure during pregnancy on the uterine artery transcriptome, and gain insight into mechanisms underlying alcohol-mediated uterine artery dysfunction. Pregnant Sprague-Dawley rats assigned to Pair-Fed Control or Alcohol groups, received a once-daily orogastric gavage in a binge paradigm. RNA-sequencing using Illumina NextSeq 500, identified 13,941 genes; 40 significantly altered genes were altered by log2(fold change) > 2; 27 genes were upregulated and 13 were downregulated in the Alcohol group. Transcripts altered included those which encode for aldehyde dehydrogenases, matrix metalloproteases, and molecules vital for vasodilation and vascular remodeling. Biological pathways that were disproportionally altered by alcohol were proline and citrulline biosynthesis/metabolism. Disruption of these pathways suggests candidate mechanism(s) for alcohol-mediated impairments to the proteome and vascular function.
