Summary: The study identified a teleost SNX8 cDNA from grass carp, which was significantly up-regulated after infection and mainly distributed in the endoplasmic reticulum. CiSNX8 may negatively regulate the RLR signaling pathway and interact with multiple proteins, suggesting its involvement in innate immune response through different molecular mechanisms.

Summary: This study investigated the immune protective effects of an inactivated F. columnare vaccine. The results showed that when white oil adjuvant was used as a booster, the relative percent survival (RPS) after 8 weeks of vaccination was 34% and 61%, respectively. Furthermore, the inactivated vaccine comprising an appropriate antigen isolate with white oil adjuvant as a booster can provide effective protection in grass carp.

Summary: The study illustrates that excessive lipid accumulation in farmed fish liver may be a protective response to exogenous fatty acids. Inhibition of DGAT1 and DGAT2 in grass carp hepatocytes shows that DGAT1 is responsible for lipid droplet formation while DGAT2 promotes lipid droplet fusion. This indicates a differential role of DGAT1 and DGAT2 in lipid metabolism and liver health in farmed fish.

Summary: This study used a lipidomic approach to investigate lipid profiling changes in grass carp kidney cells upon GCRV infection. A total of 97 lipid species were identified with 85 up-regulated and 12 down-regulated upon infection, mainly accumulation of neutral triacylglycerols. Metabolic pathway analysis showed enrichment in signaling and immune response pathways, such as regulation of autophagy, indicating potential novel defense strategies for viral hemorrhagic disease.

Summary: Cadmium is a dominant metal pollutant in aquatic environments that affects ion balance, oxidative stress, and immune responses in aquatic organisms. The addition of calcium can mitigate the toxicity of cadmium by reducing its accumulation in tissues, maintaining ion balance, alleviating oxidative stress, and regulating ATPase activity and gene expression.

Summary: This study isolated 45 bacterial strains of F. columnare from grass carp in various provinces of China, identifying three genotypes with genomovar I being the dominant type. Analysis revealed genetic differences among the three genomovars, with a closer relationship between genomovar I and II. The study provides insight into the genetic diversity of F. columnare in Chinese grass carp.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
