Oncogenic stimulation shows a rise in reactive oxygen species (ROS), and ROS can eventually induce carcinogenesis by causing DNA damage. In this context, this study aims to evaluate some biochemical and genotoxic changes in the control of cell death caused by NaBu (Sodium butyrate). treatment in breast cancer cells. NaBu's impact on cell proliferation was determined via WST-1 assay. The lipid peroxidation (MDA), reduced glutathione (GSH), Nitric Oxide (NO), hydrogen peroxide (HO), and superoxide dismutase (SOD) enzyme levels were determined biochemically. NaBu-induced genotoxic damage was estimated via single-cell gel electrophoresis (SCGE). NaBu reduced cell viability and potentially induced GSH, but decreased SOD enzyme activity and the level of MDA and NO decreased also HO decreased at different times and NaBu concentrations. Higher NaBu concentrations amplified DNA damage in MCF-7 cells compared to the control group. NaBu shows anticancer and genotoxic effects, especially through antioxidant enzymes, one of the oxidative stress parameters in breast cancer. However, the anticancer and genotoxic effects of NaBu is changed in the oxidative stress parameters with time and treatment concentration of NaBu in MCF-7 cells. Furthermore, his oxidative stress-dependent effect changes need to be clarified by further evaluation with molecular and more biochemical parameters.
致癌刺激会导致活性氧(ROS)水平升高,而ROS最终可通过引起DNA损伤诱导癌症发生。在此背景下,本研究旨在评估丁酸钠(NaBu)处理对乳腺癌细胞死亡控制方面的一些生化和遗传毒性变化。通过WST-1检测确定NaBu对细胞增殖的影响。通过生化方法测定脂质过氧化(MDA)、还原型谷胱甘肽(GSH)、一氧化氮(NO)、过氧化氢(HO)和超氧化物歧化酶(SOD)的酶水平。通过单细胞凝胶电泳(SCGE)评估NaBu诱导的遗传毒性损伤。NaBu降低了细胞活力,并可能诱导GSH升高,但降低了SOD酶活性,MDA和NO水平也降低,不同时间和NaBu浓度下HO也降低。与对照组相比,较高浓度的NaBu使MCF-7细胞中的DNA损伤加剧。NaBu显示出抗癌和遗传毒性作用,尤其是通过抗氧化酶,这是乳腺癌氧化应激参数之一。然而,在MCF-7细胞中,NaBu的抗癌和遗传毒性作用会随时间以及NaBu处理浓度在氧化应激参数方面发生变化。此外,这种氧化应激依赖性效应变化需要通过更多分子和生化参数进行进一步评估来阐明。
