Shrimp with an average body weight of (0.50 ± 0.09) g were reared in 30 glass jars with a working volume of 2.5 L at a density of 20 ind/L. Shrimp were reared for 5 d for each treatment, which included the biofloc system without and with 106 colony forming unit (CFU) per mL probiotic. The regular clear water system was used as control. All treatment groups were challenged with 103, 105, and 107 CFU/mL V. parahaemolyticus. For the negative control, shrimp were reared without V. parahaemolyticus. The results showed that the density of V. parahaemolyticus cocultured with P. piscicida 1Ub decreased and the density of V. parahaemolyticus in rearing water and shrimp body in the probiotic-treated group was lower than that in the control group (P < 0.05). The survival and immune response (total hemocyte count, phagocytic activity, respiratory burst, phenoloxidase, and superoxide dismutase) of shrimp in the probiotic group was higher than that in the positive control (P < 0.05). Moreover, supplementing the biofloc system with the probiotic could protect shrimp hepatopancreas from damage caused by V. parahaemolyticus, regardless of bacterial density. Thus, the supplementation of the probiotic P. piscicida 1Ub in the biofloc system could significantly protect and increase the resistance of shrimp to V. parahaemolyticus infection.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"9 6","pages":"Pages 967-974"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74924612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were a lot of research on the correlation between C-myc and human viruses. However, the study about C-myc related to aquatic species virus is very limited. In the present study, the qRT-PCR, cellular immunofluorescence and western blotting determination data reported that C-myc and glutaminase (GLS) genes were significantly upregulated when grouper fin cells (GF-1) were infected with red grouper nervous necrosis virus (RGNNV). After knocking down the C-myc gene, the mRNA and protein levels of GLS, capsid protein (CP) and RNA polymerase (RdRp) of RGNNV were significantly reduced in RGNNV-infected GF-1 cells and the overexpression of the C-myc gene remarkably promoted these genes, which indicated that the replication of the virus and GLS gene were positively regulated by C-myc in RGNNV-infected GF-1 cells. In addition, supplementation of exogenous ATP can partially restore viral replication when RGNNV-infected GF-1 cells were cultured in glutamine-free medium, which confirmed that the glutamine was decomposed into ATP to provide energy for viral replication. Further studies confirmed that overexpression of C-myc can increase the content of ATP in normal cells. To sum up, these data suggested that activation of C-myc gene affected viral replication by regulating GLS expression to drive glutamine dissolution.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"9 6","pages":"Pages 929-936"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82520737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
