Abstract

The kidney flushes out toxic substances and metabolic waste products, and homeostasis is maintained owing to the kidney efforts. Unfortunately, kidney disease is one of the illnesses with a poor prognosis and a high death rate. The current investigation was set out to assess erythropoietin (EPO) potential therapeutic benefits against thioacetamide (TAA)-induced kidney injury in rats. EPO treatment improved kidney functions, ameliorated serum urea, creatinine, and malondialdehyde, increased renal levels of reduced glutathione, and slowed the rise of JAK2, STAT5, AMPK, and their phosphorylated forms induced by TAA. EPO treatment also greatly suppressed JAK2, Phosphatidylinositol 3-kinases, and The Protein Kinase R-like ER Kinase gene expressions and mitigated the histopathological alterations brought on by TAA toxicity. EPO antioxidant and anti-inflammatory properties protected TAA-damaged kidneys. EPO regulates AMPK, JAK2/STAT5, and pro-inflammatory mediator synthesis.

摘要

肾脏通过排泄有毒物质和代谢废物来维持体内环境的稳定。然而,不幸的是,肾脏疾病是预后较差和死亡率较高的疾病之一。本研究旨在评估促红细胞生成素 (EPO) 对硫代乙酰胺 (TAA) 诱导的大鼠肾损伤的潜在治疗作用。EPO 治疗可改善肾功能,降低血清尿素、肌酐和丙二醛水平,增加肾脏还原型谷胱甘肽水平,并减缓 TAA 诱导的 JAK2、STAT5、AMPK 及其磷酸化形式的升高。EPO 治疗还能显著抑制 JAK2、磷脂酰肌醇 3-激酶和蛋白激酶 R 样内质网激酶基因的表达,并减轻 TAA 毒性引起的组织病理学改变。EPO 的抗氧化和抗炎特性可以保护 TAA 损伤的肾脏。EPO 可调节 AMPK、JAK2/STAT5 和促炎介质的合成。
