Abstract

The contamination of food and feed by mycotoxins, particularly zearalenone (ZEA) and deoxynivalenol (DON), is a global issue. Prenatal exposure to ZEA and DON can result in congenital cardiac malformations in fetuses. Addressing the prevention and mitigation of embryonic cardiotoxicity caused by these toxins is crucial. Citrus limonoid nomilin (NOM) is an extract known for its pathological properties in various diseases. This study investigated the potential mechanism of NOM in mitigating cardiotoxicity caused by ZEA and DON co-exposure in a zebrafish model. The findings indicated that NOM pretreatment alleviated cardiac developmental toxicity induced by ZEA and DON and normalized the expression of key genes involved in heart development, including gata4, vmhc, nkx2.5, and sox9b. Co-exposure to NOM, ZEA, and DON enhanced SOD and catalase activity, increased glutathione levels, and reduced ROS and malondialdehyde production. Furthermore, NOM reduced cardiac oxidative damage by activating the Keap1/Nrf2 signaling pathway. In summary, this study offers new insights for preventive interventions against congenital heart disease caused by mycotoxin exposure.

诺米林通过 Keap1/Nrf2 信号通路逆转斑马鱼同时暴露于玉米赤霉烯酮和脱氧雪腐镰刀菌烯醇引起的心脏毒性

霉菌毒素，特别是玉米赤霉烯酮（ZEA）和脱氧雪腐镰刀菌烯醇（DON）对食品和饲料的污染是一个全球性问题。产前接触玉米赤霉烯酮（ZEA）和脱氧雪腐镰刀菌烯醇（DON）会导致胎儿先天性心脏畸形。预防和减轻这些毒素造成的胚胎心脏毒性至关重要。柑橘类柠檬素诺米林（NOM）是一种提取物，因其在多种疾病中的病理特性而闻名。本研究调查了 NOM 在斑马鱼模型中减轻 ZEA 和 DON 共同暴露引起的心脏毒性的潜在机制。研究结果表明，NOM预处理可减轻ZEA和DON诱导的心脏发育毒性，并使参与心脏发育的关键基因（包括gata4、vmhc、nkx2.5和sox9b）的表达正常化。同时暴露于 NOM、ZEA 和 DON 可增强 SOD 和过氧化氢酶的活性，提高谷胱甘肽水平，减少 ROS 和丙二醛的产生。此外，NOM 还能通过激活 Keap1/Nrf2 信号通路减少心脏氧化损伤。总之，这项研究为预防性干预霉菌毒素暴露引起的先天性心脏病提供了新的见解。

期刊介绍： Plant Foods for Human Nutrition (previously Qualitas Plantarum) is an international journal that publishes reports of original research and critical reviews concerned with the improvement and evaluation of the nutritional quality of plant foods for humans, as they are influenced by: - Biotechnology (all fields, including molecular biology and genetic engineering) - Food science and technology - Functional, nutraceutical or pharma foods - Other nutrients and non-nutrients inherent in plant foods
