In the present study, the anti-proliferative and apoptotic potential of in lung cancer was assessed. Silver nanoparticles (AgNPs) of were synthesized using an ethanolic extract and characterized by adopting various parameters. Herein, the eco-friendly, cost-effective, and green synthesis of AgNPs was evaluated using an ethanolic extract of . The as-synthesized AgNPs were then characterized using various characterization techniques, such as UV-visible spectroscopy (UV-vis), X-ray powder diffraction (XRD), dynamic light scattering (DLS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The AgNPs are crystalline, spherical, and highly stable AgNPs of varying sizes in the range of 5-20 nm. The anticancer activity of the ethanolic extract of and its AgNPs was determined using an MTT assay. The results indicated that, although both samples showed prominent anti-proliferative activity on lung cancer cell lines, the AgNPs of were found to be more potent than the ethanolic extract. Further, apoptosis induction ability was evaluated by FITC Annexin V and PI staining, the results of which demonstrated the efficiency of the ethanolic extract of and its AgNPs in causing oxidative stress and subsequent cellular death. This was subsequently further confirmed by measuring the mitochondrial membrane potential after staining the cells with JC1. The apoptotic mode of cell death was further confirmed by DNA fragmentation and caspase assays using Western blot analysis.
在本研究中,评估了[提取物名称]在肺癌中的抗增殖和凋亡潜力。使用乙醇提取物合成了[提取物名称]的银纳米颗粒(AgNPs),并采用各种参数对其进行了表征。在此,使用[提取物名称]的乙醇提取物评估了AgNPs的生态友好、成本效益高的绿色合成方法。然后,使用各种表征技术对合成的AgNPs进行表征,如紫外可见光谱(UV-vis)、X射线粉末衍射(XRD)、动态光散射(DLS)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)。AgNPs是结晶的、球形的,并且是尺寸在5-20nm范围内变化的高度稳定的AgNPs。使用MTT测定法测定了[提取物名称]的乙醇提取物及其AgNPs的抗癌活性。结果表明,尽管两个样品在肺癌细胞系上均显示出显著的抗增殖活性,但发现[提取物名称]的AgNPs比乙醇提取物更有效。此外,通过FITC膜联蛋白V和PI染色评估了凋亡诱导能力,其结果证明了[提取物名称]的乙醇提取物及其AgNPs在引起氧化应激和随后的细胞死亡方面的效率。在用JC1对细胞进行染色后,通过测量线粒体膜电位进一步证实了这一点。通过使用蛋白质免疫印迹分析的DNA片段化和半胱天冬酶测定进一步证实了细胞死亡的凋亡模式。
