Summary: Erythroferrone is a red blood cell regulator produced in mammalian bone marrow and extramedullary sites. This study investigated its function in European sea bass and found that it responds to experimental anemia by increasing expression and suppressing hepcidin production, similar to mammals. However, during bacterial infection, Erythroferrone is downregulated while hepcidin levels increase.

Summary: This study demonstrates that juvenile sea bass exposed to oil spills exhibit transient behavioral impairments, with a dose-response relationship observed. Recovery capacities were seen within the first 10 days post-exposure, although fish may require more time for full recovery. The alterations in behavior may be attributed to neurosensory or physiological defects caused by oil exposure, leading to sedative behaviors resembling anesthesia.

Summary: The study revealed that estrogen signaling is involved in thymus maturation in European sea bass, with esr2b and gpera playing key roles during medulla maturation. The expression of estrogen receptors in the spleen was low, and estrogen exposure was found to impact the proliferation/migration of specific T cell populations.

Summary: This study explores the use of an oscilloscope coupled with a signal generator to evaluate changes in the electrical conductivity of skeletal muscle and find a quantitative parameter for postmortem interval (PMI) estimation. The results show that the oscilloscope, especially the root mean square (RMS) measured parameter, is a promising technology for studying muscle properties during the early postmortem interval. It is a rapid, non-destructive, and inexpensive method. However, further studies are needed to validate this technology for real-time field investigations.

Summary: Temperature changes can affect the activity, function, and well-being of teleosts. This study investigated the early larval development of European sea bass at different temperatures and found temperature-specific miRNA expression that targeted genes involved in reproduction and immune response. The study also observed temperature-specific effects on growth, sex, vision, and skeletal deformities.

Summary: The study found that exposure to titanium dioxide nanoparticles and cadmium individually resulted in genotoxic effects, while co-exposure did not cause any genomic damage or apoptosis.

Summary: Our study on European sea bass reveals that TRγ cells develop earlier than TRβ cells, with the thymus showing the highest expression of TRγ. TRγ cells are mainly distributed in peripheral blood and lymphoid organs, with abundant expression in gut mucosa. Microalgae-based diet can significantly modulate the abundance of TRγ cells in the posterior intestine, potentially involved in nutritional immunity.

Summary: This review summarizes and discusses the trends and findings in scientific literature on the gut mucosa immune role in European sea bass, providing an updated overview on the gastrointestinal tract functional regionalization and defence barriers. The review also covers immune cells in two immunologically-relevant intestinal compartments, mucosal immunoglobulins, gut microbiota, dietary manipulation impacts, and oral vaccination strategies for sea bass vaccine delivery.

Summary: Maternal diabetes affects heart development and alters the activation of FOXO1 and expression of target genes involved in cardiovascular formation during embryonic heart development. This leads to increased oxidative stress and pro-inflammatory cardiac development, as well as altered expression of proteolytic enzymes that regulate cardiac function.

Summary: The presence of microplastics in seafood, particularly in farmed fish, is a concerning issue as it poses potential risks to human health. A study conducted in Tenerife, Spain found that 65% of the examined fish cultivated in coastal waters contained microplastics in their gastrointestinal tracts. Fibres and fragments were the predominant shapes of microplastics detected, with varying compositions.

Summary: Temperature variations significantly affect the growth and development of European seabass. Metabolites such as L-cysteine, taurocholic acid, UDP-glucose, and L-thyroxine were identified as potential markers of growth, with changes in pathways related to glucose metabolism, arginine and proline metabolism, and other key metabolic processes.

Summary: The study found that chlorinated seawater at typical concentrations can affect the behavior of juvenile seabass, resulting in a decrease in the number of fish present. While seabass are attracted to areas with chlorination when food is available, they are more likely to move away once the food supply is reduced.

Summary: Regulatory assessment of chemical effects requires validated tests across different environments and organisms. This study developed a new exposure protocol using European sea bass larvae, assessing both traditional toxicological values and behavioral responses. Results showed the suitability of sea bass for early-life stage toxicity tests.

Summary: This study investigated the association of vgll3 and six6 genes in the domestication of gilthead seabream and European seabass. The results revealed significant allele frequency differences between farmed and wild populations in both species. Chromosome-level analysis also identified highly differentiated regions at varying distances from the candidate genes. Additionally, noteworthy genomic features were found in both species. These findings highlight the potential role of vgll3 and six6 in the maturation and growth of gilthead seabream and European seabass, emphasizing the need for further research on their conserved function.
