<b>Background and Objective:</b> Cancer is a complex interaction among multiple signalling pathways involving a variety of target molecules. Nanoparticles were used in cancer treatment because of their intrinsic anticancer properties. The use of plant extracts in the preparation of metallic nanoparticles as a convenient substitute has been proposed. This study assessed the cytotoxic, antioxidant and apoptotic effects of copper nanoparticles shelled with either turmeric or sumac biosynthesized as core-shell nanostructures on the liver tumour cell line (Huh-7). <b>Materials and Methods:</b> The nanostructures were synthesized by sonochemical method and characterization was done to confirm the successful synthesis within the nanoscale. Cytotoxicity of nanostructures was investigated on Huh-7 and normal kidney epithelial cell lines (VERO). Malondialdehyde, nitric oxide, reduced glutathione and superoxide dismutase were estimated in cell lysate to assess the antioxidant properties of nanostructures. Caspase-3 was also measured as an apoptotic marker. <b>Results:</b> Both nanostructures had low IC<sub>50</sub> on Huh-7 cells and a non-toxic effect on VERO cells. The cytotoxic effect was coupled with a significant increase in antioxidant activities and apoptotic efficiency compared to control. <b>Conclusion:</b> The findings summarized here support the utilization of biosynthesized copper with turmeric or sumac as core-shell nanostructures as a novel chemotherapeutic drug for cancer treatment that improves antioxidant effect that modulates the side effect of cytotoxicity. Also, it is obvious that copper nanostructure biosynthesized with turmeric has a more advanced effect than that of sumac.
背景与目的:癌症是多种信号通路之间的复杂相互作用,涉及多种靶分子。纳米颗粒因其固有的抗癌特性而被用于癌症治疗。有人提议使用植物提取物制备金属纳米颗粒作为一种便捷的替代方法。本研究评估了以姜黄或漆树生物合成的核壳纳米结构包裹的铜纳米颗粒对肝癌细胞系(Huh-7)的细胞毒性、抗氧化和凋亡作用。
材料与方法:通过声化学方法合成纳米结构,并进行表征以确认在纳米尺度内成功合成。研究了纳米结构对Huh-7和正常肾上皮细胞系(VERO)的细胞毒性。测定细胞裂解物中的丙二醛、一氧化氮、还原型谷胱甘肽和超氧化物歧化酶,以评估纳米结构的抗氧化特性。还测量了半胱天冬酶-3作为凋亡标志物。
结果:两种纳米结构对Huh-7细胞的半数抑制浓度(IC₅₀)都很低,对VERO细胞无毒性作用。与对照组相比,细胞毒性作用伴随着抗氧化活性和凋亡效率的显著增加。
结论:此处总结的研究结果支持将以姜黄或漆树为核壳纳米结构生物合成的铜作为一种新型化疗药物用于癌症治疗,这种药物可提高抗氧化作用,调节细胞毒性的副作用。此外,显然以姜黄生物合成的铜纳米结构比漆树的效果更显著。
