The hepatopancreas of plays a crucial role in metabolism and immune response, encompassing vital physiological functions. In our study, we established a hepatopancreatic injury model using thioacetamide (TAA) and evaluated the therapeutic potential of a commercial astaxanthin-based product (AST-product) on hepatopancreatic health. The experimental framework included a control group (Con), an injury model group (M), and a treatment group (T), enabling a comprehensive analysis of the effects of treatments on hepatopancreatic biochemical markers, tissue architecture, gene expression, and metabolic pathways. The biochemical results indicated significant oxidative damage and fibrosis in the M group post-TAA treatment, evidenced by increased malondialdehyde (MDA) levels, decreased superoxide dismutase (SOD) activity, and the disruption of tubular structures. Conversely, treatment with the AST-product significantly reduced MDA levels and ameliorated oxidative stress. Histological evaluations using hematoxylin and eosin (HE) and Sirius Red staining confirmed that the AST-product preserved tubular integrity and inhibited fibrosis progression. Metabolomic profiling revealed that the AST-product modulated key metabolic pathways, including arginine and proline metabolism, porphyrin metabolism, and nucleotide metabolism, which are critical for maintaining energy supply and antioxidative capabilities. This modulation mitigated the TAA-induced oxidative damage. Moreover, qPCR analysis demonstrated that the AST-product downregulated the pro-apoptotic gene CASP2, upregulated the energy metabolism-related gene NDUFA7, and enhanced the expression of the immune-related gene lysozyme, thereby boosting pathogen resistance. These findings elucidate the robust protective effects of the AST-product on hepatopancreatic health in , highlighting its potential to reduce oxidative stress, inhibit fibrosis, and enhance immune responses. This study provides a novel strategy for improving health in aquaculture and contributes valuable insights into hepatopancreatic protection and disease prevention in shrimp farming.
[此处原文中“of ”表述不完整,推测是某种生物,暂按“该生物的”翻译]该生物的肝胰腺在新陈代谢和免疫反应中起着至关重要的作用,涵盖重要的生理功能。在我们的研究中,我们使用硫代乙酰胺(TAA)建立了肝胰腺损伤模型,并评估了一种基于虾青素的商业产品(AST产品)对肝胰腺健康的治疗潜力。实验框架包括对照组(Con)、损伤模型组(M)和治疗组(T),能够全面分析治疗对肝胰腺生化标志物、组织结构、基因表达和代谢途径的影响。生化结果表明,TAA处理后M组存在明显的氧化损伤和纤维化,丙二醛(MDA)水平升高、超氧化物歧化酶(SOD)活性降低以及管状结构破坏证明了这一点。相反,AST产品处理显著降低了MDA水平并减轻了氧化应激。使用苏木精和伊红(HE)染色以及天狼星红染色进行的组织学评估证实,AST产品保留了管状完整性并抑制了纤维化进展。代谢组学分析表明,AST产品调节了关键代谢途径,包括精氨酸和脯氨酸代谢、卟啉代谢和核苷酸代谢,这些途径对于维持能量供应和抗氧化能力至关重要。这种调节减轻了TAA诱导的氧化损伤。此外,qPCR分析表明,AST产品下调了促凋亡基因CASP2,上调了能量代谢相关基因NDUFA7,并增强了免疫相关基因溶菌酶的表达,从而提高了对病原体的抵抗力。这些发现阐明了AST产品对该生物肝胰腺健康的强大保护作用,突出了其降低氧化应激、抑制纤维化和增强免疫反应的潜力。本研究为改善水产养殖中该生物的健康提供了一种新策略,并为对虾养殖中的肝胰腺保护和疾病预防提供了有价值的见解。
