RNA-seq and physiology analysis reveal new insights into gill response to acute hypoxia in Hybrid Yellow Catfish (Tachysurus fulvidraco ♀ × Pseudobagrus vachellii ♂)

Project description:Hypoxia is an important environmental stressor in aquatic ecosystems, with increasingly impacts on global biodiversity. Yellow catfish is an economically important farmed fish in China, which has increased dramatically. We investigated the response of hybrid yellow catfish to hypoxia under experimental conditions and focused on the analysis of the differential expression patterns of specific genes associated with hypoxia response by RNA-seq and qPCR analysis. A total of 1556 genes were captured significantly differentially expressed, and were categorized into immune response and energy metabolism. Functional enrichment analysis revealed the NLR signaling pathway play pivotal roles in hypoxia tolerance and resistance. Our study provides important insights into the physiological acclimation, immune response and defense activity of hybrid yellow catfish under hypoxia challenge.

The gills transcriptome analysis of yellow catfish (Tachysurus fulvidraco♀ × P. vachellii♂) under transport stress

Project description:Transport stress is a big threat to most teleost fish during production practice, causing mass loss to the aquaculture industry. Fish gills are mucosa-associated lymphoid tissue that directly contacted with water, which is the good choice to study the mechanism of transport stress. Gills transcriptome results revealed 1551 differentially expressed genes (744 up-regulated and 807 down- regulated) between the control and 16h transportation groups. The top 10 enriched KEGG pathways are all immune-related. After qRT-PCR validation, we found that the toll-like receptors and nod-like receptors signaling pathways mediate the gill’s immune response to transport stress: tlr5, tnfɑ, hsp90ɑ, il-1ß and map2k4 were significantly up-regulated and arrdc2 was significantly down-regulated under transport stress. These results suggested that the transport stress altered innate immunity responses and induced metabolic changes in gills of hybrid yellow catfish. In conclusion, the results provide new perspectives on immune response in yellow catfish against transport stress and provide the possibility of mining resistance genes for future optimize transportation plan.

The skin transcriptome analysis of yellow catfish (Tachysurus fulvidraco♀ × P. vachellii♂) under transport stress

Project description:The skin transcriptomes were examined by high-throughput sequencing at control group and 16 h transport group. A total of 1577 genes were differentially expressed, including 892 up-regulated and 685 down-regulated. It is interesting to note that the qPCR analysis further confirmed that the skin's immune response to transport stress was activated via Toll-like receptors (TLRs) and NOD-like receptors (NLRs) in skin: the tlr9, mfn2 and ikbke were significantly up-regulated and nfkbia, map3k7cl were significantly down-regulated. Overall results suggested that transport stress. The overall results suggest that the skin responds to transport stress by regulating mucus secretion and activating the immune signal pathway. This study will help to optimize the transport conditions for cultured hybrid yellow catfish.

The intestine transcriptome analysis of hybrid yellow catfish (Tachysurus fulvidraco♀ × P. vachellii♂) under transport stress

Project description:The transport of live fish is a routine operation in aquaculture. However, the effects of transport stress on intestines gene expression profile is poorly understood. The results from the transcriptome analysis revealed that most differentially expression genes (DEGs) were enriched in immune and metabolic related signaling pathways. Toll like receptors is a potential pathway in immune response induced by transport stress. Changes in genes related to lipid metabolism may be related to the increased metabolic expenditure for the normal body functions in a response to transport stress. In addition, changes in gene expression in the control, transport, and recovery groups were revealed that transport-induced local immune damage is reversible while metabolic disorder has hysteresis. These results provide new perspectives on immune and metabolic response in yellow catfish against transport stress and theoretical support for future optimization of their transportation.

Project description:High-density aquaculture and over-nutrition may cause fatty liver disease in hybrid yellow catfish, reduce the quality of fish products, and limit the development of the industry. In this experiment, Acanthopanax senticosus powder was used as an additive for hybrid yellow catfish feed. A control group (fed on a diet without A.senticosus) and five groups fed on diets supplemented with A.senticosus (0.5, 1, 2, 4 and 8 g A.senticosus / kg). To study the effects of A.senticosus on the growth performance and physiological parameters of hybrid yellow catfish, and to determine the effect of A.senticosus on the expression of genes related to lipid metabolism in the liver by transcriptome analysis. It was found that dietary supplementation with A.senticosus at 2-4g/kg can promote the growth of yellow catfish, reduce the levels of total cholesterol and triacylglycerol in serum, and increase the activity of fatty acid synthase involved in lipid transport in the liver. Gene expression profiles in the liver were compared between the control group and 4g/kg A.senticosus group, and 5 differentially expressed genes in these groups were identified. Annotation analyses using tools at the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases showed that these five differentially expressed genes were mainly involved in the regulation of fat metabolism. The experimental results show that adding a suitable amount of A.senticosus in the diet can reduce the expression of FADS2, ELOVL2, and PLPP3 genes in the liver and stimulate the expression of CYP24a gene, which will reduce the contents of TG and TC in the body, reduce the deposition of fat in the tissue, and promote lipid Metabolism to achieve the purpose of protecting the liver. Therefore, A.senticosus can be used as a healthy feed additive for hybrid yellow catfish, and the appropriate content in the diet is 2-4g/kg.
