Summary: This study identified five peptide sequences derived from sturgeon cartilage, four of which were newly discovered. These peptides exhibited potential anti-inflammatory activity by reducing the production of nitric oxide and interleukin-6 while increasing interleukin-10 excretion. The results suggested that these peptides acted by inhibiting the MAPK and IL-17 signaling pathways.

Summary: In this study, a dominant bacterial strain named I-702 was isolated from diseased hybrid sturgeons in China. The strain was identified as Acinetobacter lwoffii. Infection experiments showed that strain I-702 caused similar symptoms in the fish as those in natural diseased sturgeons. The study also revealed the pathogenicity and effects of A. lwoffii infection on fish.

Summary: This study explores the umami mechanism in sturgeon meat by isolating and identifying five peptides. It confirms that these peptides contribute significantly to the umami taste of sturgeon meat and also enhance its saltiness. Molecular docking and dynamics simulations reveal the specific molecular interactions between these peptides and certain residues.

Summary: This study focused on the roles of Amur sturgeon hsd3b, P450c17-I (cyp17a1), and P450c17-II (cyp17a2) in 17OHP production and their enzyme activity and mRNA expression patterns during oocyte maturation. The results showed rapid upregulation of hsd3b, downregulation of cyp17a1, and upregulation of cyp17a2 during oocyte maturation process.

Summary: The luteinizing hormone (LH) and maturation-inducing steroids (MIS) play important roles in regulating oocyte maturation and ovulation in sturgeons. By analyzing the seasonal profiles of oocyte maturational competence (OMC) and ovulatory competence, as well as the expression of 17 ovulation-related genes, the molecular mechanisms underlying the acquisition of ovulatory competence in sturgeons have been revealed.

Summary: Studying the immune response of hybrid sturgeon to Aeromonas veronii infection, this research isolated and identified a bacterial strain from affected fish. The study observed severe histopathological changes and significant alterations in blood lymphocytes and antioxidative enzyme levels during the infection. The findings provide valuable insights into the immune response of hybrid sturgeon against A. veronii infection.

Summary: This study examined the effects of dietary lipid levels on the growth and health of Amur sturgeon. The results showed that a lipid level of 20.31% in the diet resulted in the optimal growth performance. Low or high lipid diets negatively affected growth and survival rate, while high lipid diets led to excessive lipid deposition, oxidative stress, lipid metabolism disorder, and inflammation in the fish.

Summary: This study investigated the effects of LH-A2 on gonad development in juvenile A. schrenckii through transcriptome profiling analysis. The results showed that LH-A2 promotes the secretion of E2 and inhibits the secretion of Testo, and has more regulatory effects on the gonads than the pituitary. The main enriched metabolic pathways include signal transduction, immune system, endocrine system, and lipid metabolism.

Summary: This study found that l-Arginine and l-Histidine can partially replace sodium chloride in the preparation of Amur sturgeon surimi gels, with gel properties similar to normal salt content gels. Although it may result in a reddish color of the gels, sensory evaluation showed positive results.

Summary: In this study, the effect of dietary l-Alanyl-l-glutamine (Ala-Gln) supplementation on Amur sturgeon was investigated. It was found that the growth performance of the fish significantly improved with Ala-Gln supplementation. Transcriptome analysis revealed that the supplementation altered the expression of multiple genes and pathways involved in cytokine-cytokine receptor interaction, lipid metabolism, and other biological processes. These findings provide a comprehensive insight into the mechanisms underlying the effects of Ala-Gln supplementation in Amur sturgeon.

Summary: In this study, the first systematic full-length transcriptome dataset of Amur sturgeon was generated using Iso-Seq and RNA-Seq analysis. It was found that oxidized fish oil (OFO) might induce cancers, endocrine disorder, and carbohydrate metabolism disruption in Amur sturgeon. Additionally, key genes and pathways involved in the response to dietary OFO were identified.

Summary: The effects of a low-protein-high-starch diet on the growth performance, glucose and lipid metabolism in Amur sturgeon were investigated. The results showed that the diet did not compromise growth performance, increased feeding rate, promoted the deposition of whole-body protein, and maintained normal plasma glucose levels. The diet also inhibited lipogenesis, accelerated lipolysis, and promoted whole-body protein deposition.

Summary: Research has shown that cartilage containing chondroitin sulfate and protein has versatile bioactivities. Ethanol-soluble hydrolysates of sturgeon cartilage (ESCH) exhibit antioxidant and anti-inflammatory properties. The separated component F3 shows higher NO inhibition rate and reduces the production of proinflammatory cytokine IL-6.
