摘要： Resveratrol (RES) has been found to have immunological enhancement effects on Oreochromis niloticus. In O. nilocticus, the liver, spleen and kidney act as immune target tissues, while intestine works for nutrition sensing organ. In the present study, we determined RES administration on these immune tissues transcriptomic response in genetically improved farmed tilapia (GIFT), and further analyzed the relationship between transcriptomic response and intestinal microbiota. As results, hepatic hemosiderin and intestinal goblet cells significantly increased with RES addition. Kyoto encyclopedia of genes and genomes (KEGG) pathways associated with herpes simplex virus 1 infection, calcium signaling pathway, cell adhesion molecules, apoptosis, and mitogen-activated protein kinase (MAPK)/peroxisome proliferators-activated receptors (PPAR) signaling pathways were enriched. In particular, the differentially enriched genes (DEGs) associated pathways were present in different sampling tissues, times, and comparisons, interestingly, the PPAR signaling pathway was enriched with increasing time of RES addition. The assembled DEGs presented verified expression in the kidney, liver, spleen, and intestine tis-sues, and fabp6 was highly expressed in the intestine. Serial DEGs of fatty acid-binding proteins (fabp7, fabp7a, fabp10a) decreased in the liver and kidney, and fabp6 significantly increased in the spleen. With time, the pathways of energy metabolism, glycan biosynthesis, and metabolism decreased and increased in the intestinal metagenome. Some Candidatus branches significantly increased (C. cerribacteria and C. harrisonbacteria) and while others decreased (C. glodbacteria, etc.), whereas C. verstraetearchaeota fluctuated with RES addition. slc27a6 and dbi were negatively correlated with bacteria involved in the lipid, energy, and carbohydrate metabolism pathways. The present study suggests that RES supplementation affected lipid metabolism in immune-related organs may be related to the PPAR signaling pathway.
