Abstract

Nephrotoxicity is a common complication that limits the clinical utility of cisplatin. Ferroptosis is an iron-dependent necrotic cell death program that is mediated by phospholipid peroxidation. The molecular mechanisms that disrupt iron homeostasis and lead to ferroptosis are yet to be elucidated. In this study, we aimed to investigate the involvement of nuclear receptor coactivator 4 (NCOA4), a selective cargo receptor that mediates ferroptosis and autophagic degradation of ferritin in nephrotoxicity. Adult male Sprague-Dawley rats were randomly-assigned to four groups: control group, cisplatin (Cis)-treated group, deferiprone (DEF)-treated group, and Cis+DEF co-treated group. Serum, urine, and kidneys were isolated to perform biochemical, morphometric, and immunohistochemical analysis. Iron accumulation was found to predispose to ferroptotic damage of the renal tubular cells. Treatment with deferiprone highlights the role of ferroptosis in nephrotoxicity. Upregulation of NCOA4 in parallel with low ferritin level in renal tissue seems to participate in iron-induced ferroptosis. This study indicated that ferroptosis may participate in cisplatin-induced tubular cell death and nephrotoxicity through iron-mediated lipid peroxidation. Iron dyshomeostasis could be attributed to NCOA4-mediated ferritin degradation.

摘要

肾毒性是一种常见的并发症,限制了顺铂的临床应用。铁死亡是一种铁依赖性的坏死性细胞死亡程序,由磷脂过氧化介导。破坏铁平衡并导致铁死亡的分子机制尚不清楚。在这项研究中,我们旨在研究核受体共激活因子 4(NCOA4)的参与,NCOA4 是一种选择性的货物受体,介导铁死亡和铁蛋白的自噬降解在肾毒性中的作用。成年雄性 Sprague-Dawley 大鼠随机分为四组:对照组、顺铂(Cis)处理组、去铁酮(DEF)处理组和 Cis+DEF 联合处理组。分离血清、尿液和肾脏进行生化、形态计量学和免疫组织化学分析。铁积累导致肾小管细胞发生铁死亡性损伤。用去铁酮治疗突出了铁死亡在肾毒性中的作用。NCOA4 的上调与肾组织中铁蛋白水平降低平行,似乎参与了铁诱导的铁死亡。本研究表明,铁死亡可能通过铁介导的脂质过氧化参与顺铂诱导的肾小管细胞死亡和肾毒性。铁代谢失衡可能归因于 NCOA4 介导的铁蛋白降解。
