Bisphenol S (BPS), an analog of bisphenol A (BPA), has been frequently detected in consumer products, food wrappers, plastics, and thermal papers. Since the liver is a hub of metabolic and detoxification pathways, thus intimately related to BPS presence in the environment and body. The current study was designed to investigate the effects of BPS administration in an animal model. Twenty-five male Wistar rats weighing 175 ± 25 g were randomly divided into control and treated groups. The control group was further divided into group I (no treatment) and group II (corn oil), whereas the treatment group was divided into D-I (40 mg/kg/day), D-II (200 mg/kg/day), and D-III (400 mg/kg/day) groups, getting oral doses of BPS for 15 days. Data analysis showed a significant statistical increase in hepatic enzymes ALT (33.4%), AST (25.4%), and ALP (529.6%) in the D-III group along with the development of hypercholesterolemia and hypertriglyceridemia in all BPS groups. Aberrant mRNA expressions of some key hepatic iron regulatory genes and inflammatory mediators were evident through qRT-PCR. Bisphenol S caused congestion of central vein from mild to moderate in hepatic sections. In conclusion, our investigation insinuates BPS intoxication potential and therefore may not be a safe alternative to BPA.
双酚 S(BPS)是双酚 A(BPA)的一种类似物,经常在消费品、食品包装、塑料和热敏纸中被检测到。由于肝脏是代谢和解毒途径的中心,因此与环境和体内 BPS 的存在密切相关。本研究旨在动物模型中研究 BPS 给药的影响。25 只雄性 Wistar 大鼠,体重 175±25g,随机分为对照组和治疗组。对照组进一步分为 I 组(无处理)和 II 组(玉米油),而治疗组分为 D-I 组(40mg/kg/天)、D-II 组(200mg/kg/天)和 D-III 组(400mg/kg/天),每天口服 BPS 15 天。数据分析显示,D-III 组的肝酶 ALT(33.4%)、AST(25.4%)和 ALP(529.6%)显著升高,所有 BPS 组均出现高胆固醇血症和高甘油三酯血症。qRT-PCR 显示一些关键的肝铁调节基因和炎症介质的 mRNA 表达异常。BPS 引起肝组织中央静脉从轻度到中度充血。总之,我们的研究暗示 BPS 中毒的可能性,因此可能不是 BPA 的安全替代品。
