Transcription profiling of zebrafish brain and liver in adult female after starvation

ABSTRACT: We used microarray analyses in adult female zebrafish (Danio rerio) to identify metabolic pathways regulated by starvation in two key organs that 1) serve biosynthetic and energy mobilizing functions (liver) and 2) consume energy and direct behavioral responses (brain). Starvation affected the expression of 574 transcripts in the liver, indicating an overall decrease in metabolic activity, reduced lipid metabolism, protein biosynthesis and proteolysis, and cellular respiration, and increased gluconeogenesis. Starvation also regulated expression of many components of the Unfolded Protein Response, the first such report in a species other than yeast (Saccharomyces cerevisiae) and mice (Mus musculus). The response of the zebrafish hepatic transcriptome to starvation was strikingly similar
