[Abstract]  Assays for superoxide dismutase (SOD) and catalase (CAT) activities are widely employed to indicate antioxidant responses underlying the toxic effects of test chemicals. Yet, earlier studies mainly described the procedures as performed according to manufacturer’s instructions without modifications that are specific to any organisms. The present protocol describes the steps in analyzing the superoxide dismutase (SOD) and catalase (CAT) activities in C. elegans, which is a model organism that can be used to study effects of pharmaceutical compounds and environmental pollutants. The main steps include: (1) sample preparation; (2) total protein assay; (3) SOD activity assay; (4) CAT activity assay; and (5) medium list and formula, and also data analysis and performance notes. [摘要]  超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性的测定被广泛用于表明测试化学品的毒性作用的抗氧化反应。 然而,早期的研究主要描述了根据制造商的说明进行的程序,而无需对任何生物体特异的修改。 本方案描述了分析线虫中超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性的步骤,它是可用于研究药物化合物和环境污染物的影响的模型生物。 主要步骤包括:(1)样品制备; (2)总蛋白测定; (3)SOD活性测定; (4)CAT活性测定; 和(5)中等名单和公式,以及数据分析和绩效说明。
【背景】生物标志物是对化学,药剂或治疗干预的响应而检查生物和病原过程至关重要的。生物体内的各种生物过程导致引起氧化应激的活性氧(ROS)。为了应对这种氧化应激,生物体可以部署超氧化物歧化酶(SOD)和过氧化氢酶(CAT)以清除ROS,以保护细胞的稳态(Balaban等,2005)。一方面,各种化学物质(污染物)可以阻止这种抗氧化反应,并扰乱包括人类在内的生物体的健康。另一方面,许多药物旨在加强抗氧化反应以改善健康。因此,SOD和CAT的活动对于反映化学品或/和药物的潜在影响非常重要。
