BPA is still the subject of extensive research due to its widespread use, despite its significant toxicity resulting not only from its negative impact on the endocrine system but also from disrupting the organism's oxidative homeostasis. At the molecular level, bisphenol A (BPA) causes an increased production of ROS and hence a change in the redox balance, mitochondrial dysfunction, and modulation of cell signaling pathways. Importantly, these changes accumulate in animals and humans, and BPA toxicity may be aggravated by poor diet, metabolic disorders, and coexisting diseases. Accordingly, approaches using antioxidants to counteract the negative effects of BPA are being considered. The preliminary results that are described in this paper are promising, however, it should be emphasized that further studies are required to determine the optimal dosage and treatment regimen to counteract BPA toxicity. It also seems necessary to have a more holistic approach showing, on the one hand, the influence of BPA on the overall human metabolism and, on the other hand, the influence of antioxidants in doses that are acceptable with the diet on BPA toxicity. This is due in part to the fact that in many cases, the positive effect of antioxidants in in vitro studies is not confirmed by clinical studies. For this reason, further research into the molecular mechanisms of BPA activity is also recommended.
双酚A(BPA)因其广泛使用,仍是广泛研究的对象,尽管它具有显著毒性,这不仅源于其对内分泌系统的负面影响,还源于破坏生物体的氧化稳态。在分子水平上,双酚A(BPA)会导致活性氧(ROS)生成增加,进而导致氧化还原平衡改变、线粒体功能障碍以及细胞信号通路的调节。重要的是,这些变化在动物和人类体内会累积,而不良饮食、代谢紊乱和并存疾病可能会加剧双酚A的毒性。因此,正在考虑使用抗氧化剂来抵消双酚A负面影响的方法。本文所述的初步结果很有前景,然而,应该强调的是,需要进一步研究以确定抵消双酚A毒性的最佳剂量和治疗方案。似乎还需要一种更全面的方法,一方面显示双酚A对人类整体新陈代谢的影响,另一方面显示饮食中可接受剂量的抗氧化剂对双酚A毒性的影响。部分原因在于,在许多情况下,体外研究中抗氧化剂的积极作用并未得到临床研究的证实。因此,也建议进一步研究双酚A活性的分子机制。
