The potential reprotoxicity of bifenthrin remains unclear if only the common clinical indicators of reproductive disease are examined. The present study aimed to investigate the efficacy of , a microalga rich in antioxidant compounds, against bifenthrin-induced testicular oxidative damage in male mice. At the first, we demonstrate that administration of bifenthrin resulted in a decline of testosterone level and in deterioration of sperm quality that was correlated with significant transcription changes of some specific mRNA and microRNA involved in cholesterol transport, testosterone synthesis, and spermatogenesis. At the biochemical level, we found that oxidative stress was obvious in the bifenthrin group, as evidenced by increase in malondialdehyde (MDA), protein carbonyls (PCO), reactive oxygen species (ROS), and nitrite oxide (NO) that was correlated with activation of genes related to mitochondrial apoptotic signal pathways. We then brought, for the first time to our knowledge, solid and complete experimental evidences that administration of mice with extract was sufficient to protect against deleterious effects BF in testicular tissues by abrogating the change in antioxidant enzyme activities; the increase in MDA, PCO, and NO concentrations; and the altered expression level of miRNA and mRNA involved in spermatogenesis. We finally demonstrate that restores the production of testosterone in mice as well as epididymal sperm viability and motility. These results suggest a potential antitoxic activity of Tunisian deserving further attention.
如果仅检查生殖疾病的常见临床指标,双芬泰的潜在生殖毒性仍不清楚。本研究旨在探讨富含抗氧化化合物的微藻对雄性小鼠双芬泰诱导的睾丸氧化损伤的疗效。首先,我们证明双芬泰的给药导致睾酮水平下降和精子质量恶化,这与涉及胆固醇转运、睾酮合成和精子发生的一些特定 mRNA 和 microRNA 的转录变化相关。在生化水平上,我们发现双芬泰组的氧化应激很明显,这表现在丙二醛 (MDA)、蛋白质羰基 (PCO)、活性氧 (ROS) 和亚硝酸盐 (NO) 的增加,这与与线粒体凋亡信号通路相关的基因的激活有关。然后,我们首次提供了确凿而完整的实验证据,证明给予小鼠 提取物足以通过消除抗氧化酶活性的变化、MDA、PCO 和 NO 浓度的增加以及参与精子发生的 miRNA 和 mRNA 的表达水平的改变来防止 BF 在睾丸组织中的有害作用。我们最后证明,恢复了雄性小鼠的睾酮产生以及附睾精子的活力和活力。这些结果表明突尼斯 具有潜在的解毒活性,值得进一步关注。
