Fenpropathrin (FPT) is a synthetic pyrethroid insecticide, the persistence and accumulation in water of which could cause harmful effects on vulnerable groups like aquatic creatures, particularly posing significant risks to fish immune systems. This study aimed to investigate how environmentally relevant FPT concentrations (10–1000 μ/M) affect lipid peroxidation and Fe 2+ metabolism in Cyprinus carpio head kidney lymphocytes, and its relationship with oxidative stress and immunotoxicity. Firstly, CCK-8 results demonstrated that FPT caused a significant increase in lymphocyte death. Secondly, lymphocytes exposed to FPT could lead ferroptosis in lymphocytes, accompanied by evidence of the Fe 2+ transporter imbalance, lipid peroxidation, Fe 2+ accumulation and ferroptosis related protein increment. Thirdly, we found that FPT esposure leads to a decrease in ATP, mitochondrial DNA and NADPH/NADP + levels, and the mRNA associated with mitochondrial function-related genes (Fis1, Drp1, and OPA1) in lymphocytes. Additionally, FPT induced the increased the levels of inflammatory genes (TNF-α, IFN-γ, and IL-6) in head kidney lymphocytes. Importantly, exposure to FPT induced oxidative stress to produce intracellular ROS, disrupting the function of the CncC signaling pathway and expression disorder of xenobiotics detoxification (CYP 450 family) genes. Notably, Treatment with NAC (a ROS inhibitor, 5 μM) demonstrated that inhibiting ROS alleviated FPT-induced lymphocyte ferroptosis and inflammatory response via the ROS/CncC-xenobiotics signaling pathway. These findings not only introduces a novel approach to investigating the immunotoxicity of FPT but also offers critical insights into mitigating the adverse effects of FPT on aquatic animal health.

Spice use in traditional braised He Bao carp (Cyprinus carpio) remains empirical, and its flavor-modulating mechanisms lacks scientific elucidation. This study elucidated the differential flavor-modulating mechanisms of four natural spices—Perilla frutescens, dried tangerine peel (Citrus reticulata), lemongrass (Cymbopogon citratus), and orange peel (Citrus sinensis). Aroma-active and taste-active compounds were characterized by GC–MS, GC–IMS, E-nose, E-tongue, and molecular docking. A total of 129 volatiles were identified, including 16 shared core compounds (e.g., benzaldehyde, nonanal, geraniol). Lemongrass group yielded the highest volatile content (110.34 mg/kg) with dominant citral, geraniol, citronellol, and eugenol, while orange peel group exhibited abundant D-limonene (9.93 mg/kg, OAV > 200). Perilla frutescens group suppressed fishy odor by reducing 1-octen-3-ol, and dried tangerine peel group enriched thymol and γ-terpinene, enhancing herbal-citrus notes. Molecular docking revealed stronger binding of key pleasant odorants (–4.4 to –5.1 kcal/mol) to OR1D2 receptors than off-flavor compounds. In taste evaluation, dried tangerine peel group and lemongrass group enhanced umami perception via increased Glu (≈1.09 g/100 g) and 5′-IMP (up to 258.7 mg/100 g). Overall, natural spices distinctly modulated aroma and taste, with lemongrass group and orange peel group producing complex aromatic profiles and dried tangerine peel group improving taste balance. These findings provide mechanistic insight and practical guidance for enhancing the flavor and standardization of traditional Jiangxi cuisine.

Aquaculture research has focused on polysaccharides as they are among the most promising new-generation immunostimulant used to control aquatic diseases. The aim of this study was to investigate the immunomodulatory effects of fermented wheat bran polysaccharides (FWBPs) on juvenile common carp ( Cyprinus carpio ). Carps were fed different FWBP amounts (0%, 0.1%, 0.2%, and 0.4%) for 8 weeks and then their skin mucus and serum immune parameters, hepatopancreas antioxidant indicators, and immune-related gene expression in the intestines, kidneys, and spleen were measured. The skin mucus IgM levels significantly increased in 0.1% FWBP group, but decreased in 0.4% FWBP group. The skin mucus protease and the serum alkaline phosphatase activities increased significantly in the 0.2%, 0.1%, and 0.4% FWBP groups, respectively. The serum total Ig levels increased noticeably in the 0.1% and 0.2% FWBP groups. The highest and lowest serum lysozyme activities were observed in the 0.1% and 0.4% FWBP groups, respectively. The hepatopancreatic total superoxide dismutase activity was higher in the 0.1% FWBP group than in the control. The malondialdehyde levels decreased significantly in the 0.2% and 0.4% groups. The intestinal mRNA levels of the LZM - C and IL-10 genes were significantly higher in the 0.2% than in the 0.4% FWBP group; TNF-α was significantly upregulated in the 0.1% group. The gene expression in the kidneys did not differ significantly among the treatments, except for a significant increase in the IL-10 expression in the 0.1% treatment. Significantly elevated expression of LZM-C in 0.2% group and IL-10 in 0.1% group was observed in the spleens. TNF-α and IL-1β were significantly downregulated in the 0.4% group. These results suggest that FWBPs could be used as immunostimulant feed additives in common carp cultures.

Thiacloprid (THI) is a synthetic insecticide, the misuse is targeted chiefly to control aphid pest species in orchards and vegetables. Melatonin (MET) is a hormone that plays crucial physiological roles in anti-inflammatory capacities of fish. We explored the function of MET (100 μM) to mitigate the toxicity induced by THI (20 μM) in lymphocytes. Our results indicate that THI led to a notable rise in lymphocyte mortality. Lymphocytes exposed to THI exhibited a heightened incidence of pyroptosis, accompanied by upregulation in expression associated with pyroptosis (NLRP3, GSDMEA, and IL-18). Meanwhile, THI exposure led to a decrease in lymphocyte mitochondrial membrane potential, an increase in mtROS levels, and a reduction in intracellular ATP, DNA, and NADPH/NADP+ levels, indicating an imbalance in the mitochondrial metabolism within the lymphocytes. Additionally, these effects were reversed by MET treatment, where MitoQ treatment showed that the suppression of mtROS reduced the lymphocyte pyroptosis caused by THI via the mtROS/cGAS-STING/NF-κB axis. Importantly, MET provided defense against the immunotoxic impacts of THI by ameliorating pyroptosis and enhancing anti-inflammatory capability via the mtROS/cGAS-STING/NF-κB axis. Our research potentiates the safeguarding of cultured fish from biological hazards caused by THI and highlights the valuable application of MET in common carp.

Fatty acid synthase (FASN) is the rate-limiting core enzyme for de novo fatty acid biosynthesis in aquatic animals, yet its regulatory role in teleost cellular antioxidant defense and redox balance remains poorly characterized. In this study, we identified and bioinformatically characterized the complete coding sequence (CDS) of Jian carpFASN, which encodes a 2514-amino acid polypeptide containing five conserved polyketide synthase (PKS) catalytic domains and 188 phosphorylation sites. qRT-PCR tissue profiling revealed ubiquitousFASNtranscription across all tested tissues, with the highest abundance in liver tissue. To decipher the physiological functions ofFASN, siRNA-mediated functional depletion was performed in isolated primary Jian carp hepatocytes. Suppression of endogenousFASNexpression induced markers of oxidative damage, evidenced by significantly reduced activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) (p< 0.05), alongside elevated malondialdehyde (MDA) levels (p< 0.05). GC-MS detected global declines in cellular saturated, monounsaturated and polyunsaturated fatty acids, especially C14:0, C16:0 and C18:0. Transcriptionally, the6-PGDwas downregulated (p< 0.05), whereas the fatty acid oxidation genePPARαwas upregulated (p< 0.05). RNA-seq identified 13,546 differentially expressed genes, with enrichment analyses indicating transcriptional shifts associated with oxidative damage and NF-κB-related inflammatory signaling. A total of 23 hub genes related to lipid turnover and arachidonic acid metabolism were screened. Collectively, our results demonstrate thatFASNacts as an essential upstream regulator of hepatic redox balance in Jian carp.FASNdisrupts fatty acid pools and triggers metabolic–inflammatory reprogramming, offering new insights into lipid–antioxidant crosstalk in teleost hepatocytes.
