Abstract

Arsenic is widely available in the environment and arsenic toxicity is a public health problem of serious concern worldwide. Zingerone is a promising phytochemical with various pharmacological effects. In this study, the potential protective effect of zingerone against sodium arsenite (NaAsO, SA) induced nephrotoxicity was investigated. Thirty-five male Sprague-Dawley rats were divided into five different groups as control, zingerone, SA, SA + zingerone 25, SA + zingerone 50. SA was administered alone at a dose of 10 mg/kg for 14 days or given 30 min before zingerone (25 mg/kg or 50 mg/kg) treatment. At the end of the experiment, the kidney tissues was examined biochemically, molecularly and microscopically. SA toxicity was associated with increased malondialdehyde level, whereas glutathione, superoxide dismutase, catalase, and glutathione peroxidase were decreased. Administration of SA caused inflammation in the kidney tissue by upregulation of NF-κB and IL-1β, TNF-α, IL-6, iNOS, COX-2, MAPK14, MAPK15, JNK. SA administration caused apoptosis in the kidney by upregulating caspase-3 and Bax levels and downregulating Bcl-2, and autophagy by activating beclin-1. Also, SA administration showed a suppressive effect on AKT2 and FOXO1 mRNA transcript levels. All these factors impair kidney function and increase creatinine and urea levels, resulting in pathological changes and a decrease in nephrin. Treatment with zingerone at doses of 25 and 50 mg/kg significantly reduced oxidative stress, inflammation, apoptosis and autophagy in kidney tissue. In addition, it was confirmed by histological evaluation as well as serum urea and creatinine levels that kidney damage due to SA toxicity can be modulated by zingerone administration.

摘要

砷在环境中广泛存在,砷中毒是一个全球严重关注的公共卫生问题。姜辣素是一种具有多种药理作用的有前景的植物化学物质。在本研究中,研究了姜辣素对亚砷酸钠(NaAsO₂,SA)诱导的肾毒性的潜在保护作用。将35只雄性Sprague-Dawley大鼠分为五个不同组,即对照组、姜辣素组、SA组、SA + 25mg/kg姜辣素组、SA + 50mg/kg姜辣素组。SA以10mg/kg的剂量单独给药14天,或在姜辣素(25mg/kg或50mg/kg)治疗前30分钟给药。实验结束时,对肾脏组织进行生化、分子和显微镜检查。SA毒性与丙二醛水平升高有关,而谷胱甘肽、超氧化物歧化酶、过氧化氢酶和谷胱甘肽过氧化物酶水平降低。SA给药通过上调NF-κB和IL-1β、TNF-α、IL-6、iNOS、COX-2、MAPK14、MAPK15、JNK导致肾脏组织炎症。SA给药通过上调caspase-3和Bax水平以及下调Bcl-2导致肾脏细胞凋亡,并通过激活beclin-1导致自噬。此外,SA给药对AKT2和FOXO1 mRNA转录水平有抑制作用。所有这些因素都会损害肾功能并增加肌酐和尿素水平,导致病理变化和nephrin减少。25mg/kg和50mg/kg剂量的姜辣素治疗可显著降低肾脏组织中的氧化应激、炎症、细胞凋亡和自噬。此外,组织学评估以及血清尿素和肌酐水平证实,姜辣素给药可调节SA毒性引起的肾损伤。
