Organophosphates (OP) are potent pesticide commonly utilized in agricultural and domestic use. However, plentitude of data represent their side effects in different body tissues. We attempted to study whether betanin (a natural pigment) is able to mitigate some OPs-induced hepatotoxicity in primary rat hepatocytes. Cell viability, lactate dehydrogenase (LDH) leakage, reactive oxygen species (ROS) formation, lipid peroxidation (LPO), glutathione (GSH) depletion and mitochondrial depolarization were tested as toxicity markers. The outcomes revealed that betanin (25μM) significantly increased cell viability, plummeted ROS formation and LPO, restored cellular GSH reservoirs and protected mitochondria after chlorpyrifos (CPF) (300μM), diazinon (DZN) (600μM) and dichlrovos (DDVP) (400μM) treatment. Taken together, all data suggests the potential protective role of betanin in OPs-induced hepatotoxicity in which the mechanism appears to be inhibition of ROS formation and mitochondrial protection.
有机磷化合物 (OP) 是一种在农业和家庭用途中广泛使用的强效农药。然而,大量数据表明它们会对不同的身体组织产生副作用。我们试图研究甜菜碱(一种天然色素)是否能够减轻原代大鼠肝细胞中某些 OP 引起的肝毒性。细胞活力、乳酸脱氢酶 (LDH) 渗漏、活性氧 (ROS) 形成、脂质过氧化 (LPO)、谷胱甘肽 (GSH) 耗竭和线粒体去极化被用作毒性标志物进行检测。结果表明,甜菜碱(25μM)可显著提高细胞活力,降低 ROS 形成和 LPO,恢复细胞内 GSH 储备,并在毒死蜱 (CPF)(300μM)、二嗪磷 (DZN)(600μM)和敌敌畏 (DDVP)(400μM)处理后保护线粒体。综上所述,所有数据表明甜菜碱在 OP 引起的肝毒性中具有潜在的保护作用,其机制似乎是抑制 ROS 形成和保护线粒体。
