Summary: This study assessed the effects of nutritional status and visfatin injections on NAMPT mRNA expression and food intake in goldfish. The results showed that NAMPT is widely expressed in peripheral tissues and brain. Visfatin injections increased food intake and hepatic leptin and sirtuin1 expression, while decreasing expression levels of certain hormones and genes in the intestine and brain. These findings suggest that visfatin/NAMPT may play a role in regulating feeding and energy homeostasis in goldfish.

Summary: This study evaluated the effect of dietary protein to lipid ratio on the growth performance, digestive enzyme activity, body composition, serum biochemistry, immunity, and antioxidant capacity of Carassius auratus var. Pengze juveniles. The results suggest that a combination of 35.1% protein and 5.1% lipid with a protein-to-energy ratio of 24.0 is optimal for the culture of Carassius auratus var. Pengze juveniles.

Summary: Ferritin H plays a role in regulating fish immunity, particularly in hybrid offspring with highly conserved domains regulating inflammatory signals. Overexpression of Ferritin H can decrease MyD88-IRAK4 signal and antagonize NF-kappa B, TNF alpha promoter activity in fibroblast-like cell lines derived from different carp species.

Summary: This study reports the pro-inflammatory properties of recombinant goldfish M17, which enhances phagocytosis, reactive oxygen intermediate production, and macrophage chemotaxis. Goldfish macrophages treated with LPS, heat-killed and live Aeromonas hydrophila showed increased M17 mRNA levels. Recombinant M17 induced dose-dependent production of IFN gamma and IL-1 beta 1 in goldfish macrophages. Treatment with rgM17 resulted in upregulation of transcription factors involved in the differentiation of myeloid progenitors into monocytes/macrophages (Runx1 and GATA2). These findings highlight the essential role of goldfish M17 as an inflammatory cytokine for goldfish progenitor cell proliferation and differentiation.

Summary: The study demonstrated that dietary taurine levels affect intermediary metabolism, particularly carbohydrate and lipid metabolism, and improve the antioxidant status of European seabass juveniles. Additionally, while CDO expression was detected, European seabass seems unable to regulate its activity, supporting the essentiality of taurine for this species.

Summary: This study analyzed the structure and expression characteristics of the RpCSAD gene in Ruditapes philippinarum. It was found that RpCSAD1 and RpCSAD3-6 were primarily expressed in the mantle tissue, while RpCSAD2 was mainly expressed in the water tube and gonad tissue. After exposure to hyposalinity stress, the expression levels of RpCSADs were upregulated in all shell-colored groups of clams, with a significant increase observed specifically in the zebra shell-color groups. These findings suggest the involvement of taurine metabolism in the response of zebra shell-color clams to low salinity stress and highlight its critical role in adaptation mechanisms.

Summary: CD3 gamma/delta in Qihe crucian carp plays a crucial role in T cell recognition and immune response. The expression of CaCD3 gamma /3 was found to be constitutive in the spleen, liver, gill, and blood of Qihe crucian carp, and significantly changed after Poly(I:C) and A. veronii challenge. The increase in CaCD3 gamma/delta+ T lymphocytes in the spleen and gills suggests their involvement in the immune response against pathogens.

Summary: In this study, the researchers found that A. hydrophila infection in red crucian carp can cause tissue damage, physiological changes, and altered gene expression profiles in immune tissues. Transcriptome analysis revealed that the infection has a significant impact on the mitochondrial oxidative phosphorylation and metabolic regulation, connecting it to the immune response. The study also identified cellular senescence, apoptosis, necrosis, and mitogen-activated protein kinase signal pathways as crucial pathways in the kidney of the infected fish.

Summary: The E93 gene was identified and found to be widely distributed in adult tissues of the swimming crab. The expression levels of PtE93 mRNA in Y-organ and epidermis fluctuated during the molt cycle, suggesting its involvement in juvenile molting. Treatment with 20E induced PtE93 expression, while treatment with MF showed the opposite effect. The study also observed a negative correlation between PtE93 and ecdysteroid biosynthesis genes.

Summary: This study investigated the combined effects of partial dietary replacement of fish oil (FO) by vegetable oil (VO) and reduced ambient salinity on the fatty acid composition of C. labrosus juveniles. The results showed that C. labrosus is able to biosynthesise EPA and DHA from ALA, and low salinity conditions can upregulate the gene expression related to fatty acid metabolism. Fish reared on FO20 diet showed the highest amount of n-3 LC-PUFA in muscle.

Summary: Metal pollution has significant effects on aquatic environments, and metallothioneins play important roles in maintaining metal homeostasis and detoxification. This study identified two metallothionein-coding transcripts in Gammarus fossarum and investigated their organ-specific expression patterns. The results showed that mt1 was more strongly induced after cadmium exposure, and mt1 was more highly induced in the caeca compared to the gills for any metal exposure. Additionally, mt2 was more inducible in the gills than in the caeca for cadmium and zinc exposure at the individual level.

Summary: This study investigates the mechanisms underlying the activation of lipophagy in yellow catfish under high glucose-induced lipid deposition. The SIRT1-NRF2-TFEB pathway is proposed to mediate lipophagy activation, and lipophagy helps alleviate high glucose-induced lipid deposition. This study provides insights into the control of lipophagy in response to metabolic stress.
