溴酸钾(KBrO3)是一种常见的膳食添加剂,药物成分,和重要的水消毒副产品。对香豆酸(PCA)是一种天然存在的营养多酚分子,具有抗炎和抗氧化活性。当前研究的目的是检查对香豆酸对KBrO3引起的肝损伤的保护作用。五组动物-对照,KBrO3(100mg/kgbw),用KBrO3和水飞蓟素(100mg/kgbw)处理,KBrO3,其次是PCA(100mg/bw,和200mg/kgbw)随机分配给动物。老鼠被宰杀,和血液和肝脏组织用于评估血清生化分析的肝功能标志物(丙氨酸转氨酶,天冬氨酸转氨酶,碱性磷酸酶,白蛋白,和蛋白质),脂质标记和抗氧化剂标记(TBARS),谷胱甘肽过氧化物酶[GSH-Px],谷胱甘肽(GSH),和肝氧化应激(CAT)的标志物,(SOD),以及组织学H&E染色,免疫组织化学染色iNOS,和COX-2作为炎性细胞因子的标志物。PCA通过防止血液生化标志物和血脂谱的增加来预防急性肝功能衰竭。在小鼠肝脏组织中,KBrO3增加脂质指标并消耗抗氧化剂,导致JNK的增加,ERK,和p38磷酸化。此外,PCA抑制了促炎细胞因子的产生,并减少了KBrO3诱导的肝毒性的组织学改变。值得注意的是,PCA通过阻断TNF-α/NF-kB介导的炎症过程信号系统有效减轻KBrO3诱导的肝损伤。此外,在KBrO3诱导的小鼠中,PCA增加了肝谷胱甘肽(GSH)的强度,SOD,GSH-Px,过氧化氢酶,和GSH活动。总的来说,我们证明了PCA消除细胞炎症的分子证据,线粒体氧化应激,和TNF-α/NF-κB信号传导过程,从而防止KBrO3诱导的肝细胞损伤。
Potassium bromate (KBrO3) is a common dietary additive, pharmaceutical ingredient, and significant by-product of water disinfection. p-coumaric acid (PCA) is a naturally occurring nutritional polyphenolic molecule with anti-inflammatory and antioxidant activities. The goal of the current investigation was to examine the protective effects of p-coumaric acid against the liver damage caused by KBrO3. The five groups of animals-control, KBrO3 (100 mg/kg bw), treatment with KBrO3 along with Silymarin (100 mg/kg bw), KBrO3, followed by PCA (100 mg/bw, and 200 mg/kg bw) were randomly assigned to the animals. Mice were slaughtered, and blood and liver tissues were taken for assessment of the serum biochemical analysis for markers of liver function (alanine transaminase, aspartate transaminase, alkaline phosphatase, albumin, and protein), lipid markers and antioxidant markers (TBARS), glutathione peroxidase [GSH-Px], glutathione (GSH), and markers of hepatic oxidative stress (CAT), (SOD), as well as histological H&E stain, immunohistochemical stain iNOS, and COX-2 as markers of inflammatory cytokines. PCA protects against acute liver failure by preventing the augmentation of blood biochemical markers and lipid profiles. In mice liver tissues, KBrO3 increases lipid indicators and depletes antioxidants, leading to an increase in JNK, ERK, and p38 phosphorylation. Additionally, PCA inhibited the production of pro-inflammatory cytokines and reduced the histological alterations in KBrO3-induced hepatotoxicity. Notably, PCA effectively mitigated KBrO3-induced hepatic damage by obstructing the TNF-α/NF-kB-mediated inflammatory process signaling system. Additionally, in KBrO3-induced mice, PCA increased the intensities of hepatic glutathione (GSH), SOD, GSH-Px, catalase, and GSH activities. Collectively, we demonstrate the molecular evidence that PCA eliminated cellular inflammatory conditions, mitochondrial oxidative stress, and the TNF-α/NF-κB signaling process, thereby preventing KBrO3-induced hepatocyte damage.
