Modulation of the Drosophila Transcriptome by Developmental Exposure to Alcohol


ABSTRACT: Prenatal exposure to ethanol can cause fetal alcohol spectrum disorder (FASD), a prevalent and preventable pediatric disorder. Identifying genetic risk alleles for FASD is impossible in human populations, but the Drosophila genetic model can provide insights. We analyzed changes in genome-wide gene expression in 96 wild-derived inbred fly lines after exposure to alcohol during development. We found extensive sexual dimorphism in the effect of alcohol on gene expression along with effects on adult locomotor activity and sleep. Genetic networks associated with changes in gene expression include both protein-coding and non-coding transcripts, including a female-specific module of small nucleolar RNAs that regulate pseudouridylation of ribosomal RNA. These data support a regulatory role for non-coding elements in response to developmental alcohol exposure.
