摘要
背景:赭曲霉毒素 A (OTA) 是一种广泛存在于水产饲料成分中的毒素,而缺氧是养鱼业中的一个常见问题。在实践中,当饲料受到 OTA 污染时,水生动物往往对缺氧更敏感,但目前还没有这方面的研究。本研究调查了 OTA 和缺氧对草鱼肝脏的多重生物毒性,并探讨了姜黄素(CUR)的缓解作用:方法:选取720尾健康草鱼幼鱼(11.06 ± 0.05 g),随机分为4个实验组:对照组(不含OTA和姜黄素)、1.2 mg/kg OTA组、400 mg/kg CUR组和1.2 mg/kg OTA + 400 mg/kg CUR组,每组3个重复,实验60 d:结果:CUR可通过减少空泡化和核偏移来减轻因OTA和缺氧造成的组织病理学损伤。这种损伤的减轻与线粒体途径中凋亡的减轻有关,因为它降低了促凋亡蛋白 Caspase 3、8、9、Bax 和 Apaf1 的表达,同时增加了抗凋亡蛋白 Bcl-2 的表达,并通过降低 Grp78 的表达和切碎水平减轻了内质网应激(ERS)。这可能是由于 CUR 的添加提高了过氧化氢酶(CAT)和谷胱甘肽还原酶(GSH)的水平,增加了抗氧化能力,确保了呼吸链复合物 I 和 II 的正常运行,进而减少了活性氧(ROS)的大量产生,从而缓解了细胞凋亡和 ERS:总之,我们的数据证明了 CUR 在减轻 OTA 和缺氧共同造成的肝损伤方面的有效性。这项研究证实了添加天然产品以减轻水生动物毒性损伤的可行性和有效性。
Curcumin attenuates ochratoxin A and hypoxia co-induced liver injury in grass carp (Ctenopharyngodon idella) by dual targeting endoplasmic reticulum stress and apoptosis via reducing ROS content.
Background: Ochratoxin A (OTA) is a toxin widely found in aquafeed ingredients, and hypoxia is a common problem in fish farming. In practice, aquatic animals tend to be more sensitive to hypoxia while feeds are contaminated with OTA, but no studies exist in this area. This research investigated the multiple biotoxicities of OTA and hypoxia combined on the liver of grass carp and explored the mitigating effect of curcumin (CUR).
Methods: A total of 720 healthy juvenile grass carp (11.06 ± 0.05 g) were selected and assigned randomly to 4 experimental groups: control group (without OTA and CUR), 1.2 mg/kg OTA group, 400 mg/kg CUR group, and 1.2 mg/kg OTA + 400 mg/kg CUR group with three replicates each for 60 d. Subsequently, 32 fish were selected, divided into normoxia (18 fish) and hypoxia (18 fish) groups, and subjected to hypoxia stress for 96 h.
Results: CUR can attenuate histopathological damage caused by coming to OTA and hypoxia by reducing vacuolation and nuclear excursion. The alleviation of this damage was associated with the attenuation of apoptosis in the mitochondrial pathway by decreasing the expression of the pro-apoptotic proteins Caspase 3, 8, 9, Bax, and Apaf1 while increasing the expression of the anti-apoptotic protein Bcl-2, and attenuation of endoplasmic reticulum stress (ERS) by reducing Grp78 expression and chop levels. This may be attributed to the fact that the addition of CUR increased the levels of catalase (CAT) and glutathione reductase (GSH), increased antioxidant capacity, and ensured the proper functioning of respiratory chain complexes I and II, which in turn reduced the high production of reactive oxygen species (ROS), thus alleviating apoptosis and ERS.
Conclusions: In conclusion, our data demonstrate the effectiveness of CUR in attenuating liver injury caused by the combination of OTA and hypoxia. This study confirms the feasibility and efficacy of adding natural products to mitigate toxic damage to aquatic animals.
