Summary: In this study, a beta-defensin (SmBD) was identified and characterized from turbot, showing antibacterial activity against various pathogens. The protein's mode of action is likely through membrane-attack mechanism based on changes in bacterial morphology and membrane permeability.

Summary: The study demonstrates that vitamin D-3 enhances immune responses in fish, leading to lower mortality and reduced bacterial load in infected fish. Additionally, VD3 supplementation promotes bactericidal activity and modulates immune cell responses, highlighting its potential as a defense mechanism against pathogen infection in fish.

Summary: This study characterized the foxo3 in turbot and investigated its functions in liver inflammation through both in vitro and in vivo experiments. The results suggest that FoxO3 may modulate LPS-activated hepatic inflammation in turbot by decreasing proinflammatory cytokines, levels of liver enzymes, and activating specific pathways, providing valuable insights for immune regulation and potential therapies for liver inflammation in fish.

Summary: The study demonstrated that the newly isolated A. salmonicida subsp. masoucida phage vB_AsM_ZHF exhibited potent antibacterial effect against the pathogen both in vitro and in vivo, reducing bacterial burden and inflammatory response in infected turbot. This phage showed promising potential as an alternative therapeutic agent to antibiotics for controlling multidrug-resistant A. salmonicida subsp. masoucida infections in the aquaculture industry.

Summary: The study on genetic effects of inbreeding on growth trajectories in turbot revealed that inbreeding had a larger impact on body length compared to body weight and body width. The genetic effects were not linear with increasing inbreeding degrees and varied depending on the age of the fish. Additionally, there were low genetic correlations between growth traits in early growth days and later growth days.

Summary: This study investigated the influence of different LED spectra on the performance of juvenile turbot. It was found that blue spectrum resulted in the best growth performance, antioxidative activity, and pathogen resistance, while red and orange spectrum led to growth retardation and decreased antioxidative activity and pathogen resistance. Therefore, blue spectrum is recommended for rearing juvenile turbot in aquaculture systems to improve fish welfare.

Summary: The study found that the aqp family plays an important role in turbot spermatogenesis, with aqp4, aqp10, and aqp12 highly expressed in the proliferative stage, and aqp1 showing the highest expression in the mature stage. aqp11 displayed high expression levels in both proliferative and mature stages, potentially contributing significantly to the proliferation and maturation of male germ cells. Furthermore, AQP1 protein was mainly localized in male germ cells, specifically concentrated in the head of sperm within cysts, as revealed by immunohistochemical analysis.

Summary: This study analyzed the morphology of turbot tongue using macro-anatomical, light, and scanning electron microscopy. The tongue consisted of apex, body, and root, with increasing thickness from apex to root. Cone-like papillae were found on the submucosa, and taste buds, taste pores, and papillae were observed on the dorsal surface. The study provides new data on the anatomy of fish tongues.

Summary: Thirteen galectin genes have been identified in turbot, with strong expression in mucosal tissues such as skin, gills, and intestine. These genes are significantly regulated after bacterial challenge, indicating their involvement in mucosal immune response. The subcellular localization analysis revealed lgals3a presence in both the cytoplasm and nucleus. Further studies are needed to better understand the roles of galectins in mucosal immunity of teleost species.

Summary: This study aimed to investigate the effects of dietary methionine availability on muscle growth and macronutrient metabolism in turbot. The results showed that methionine deprivation inhibited fish growth, reduced protein content, and affected the expression of genes related to muscle development. It also impacted the mTOR pathway, autophagy-lysosomal system, and ubiquitin-proteasome system. Furthermore, methionine deficiency influenced amino acid metabolism and energy utilization in muscle. Excess methionine intake did not further modulate metabolism in muscle.

Summary: This study measured the responses of turbot at different concentrations of Tralopyril to determine the changes induced by long-term exposure. The results showed that Tralopyril affected immune response, synthesis and metabolism of steroids and fat, as well as the synthesis, secretion, and action of parathyroid hormone and growth hormone. The study also revealed abnormal growth and disturbance of calcium regulation caused by Tralopyril, potentially attributed to the inhibition of vitamin D receptor. This study provides scientific data for understanding the toxicological effects of Tralopyril and its potential threat to environmental health.
