摘要： Due to their high-water content and low nutritional value, jellyfish have long been considered 'dead ends' in marine food webs. However, it was revealed that silver pomfret (Pampus argenteus) preferentially hunts jellyfish, and consuming jellyfish alters intestine histology. To better understand the physiological responses of midgut tissues after consuming jellyfish, we compared the transcriptomes and proteomes of jellyfish-fed and jellyfishunfed groups, and identified 1167 differentially expressed genes (DEGs) and 471 differentially expressed proteins (DEPs). Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that unsaturated fatty acid metabolism pathways, especially cholesterol metabolism, were the most enriched biological pathways. Apolipoprotein E was downregulated at both transcriptome and proteome levels, and it was found to negatively regulate jellyfish consumption. These results provide deep insight into the molecular mechanisms regulating jellyfish consumption in Pampus argenteus.
