Abstract

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is ranked as the third most common cause of cancer-related mortality worldwide. () L. is an important medicinal plant that contains many bioactive compounds with pharmacological properties. The role of leaf extract in the biosynthesis of silver nanoparticles (AgNPs) was determined. The biosynthesized AgNPs were thoroughly characterized by UV-vis spectrophotometry, transmission electron microscopy (TEM), X-ray diffraction (XRD), and dynamic light scattering (DLS) techniques. Furthermore, the cytotoxic effect of the biosynthesized AgNPs using (SMAgNPs) against HepG2 liver cancer cells was investigated. Reactive oxygen species generation, apoptosis induction, DNA damage, and autophagy activity were analyzed. The results clearly showed that the biosynthesized silver nanoparticles inhibited the proliferation of HepG2 by significantly ( < 0.05) inducing oxidative stress, cytotoxicity, DNA damage, apoptosis, and autophagy in a dose- and time-dependent manner. These findings may encourage integrating the potential of natural products and the efficiency of silver nanoparticles for the fabrication of safe, environmentally friendly, and effective anticancer agents.

摘要

肝细胞癌(HCC)是最常见的原发性肝脏恶性肿瘤,在全球癌症相关死亡率中排名第三。()L.是一种重要的药用植物,含有许多具有药理特性的生物活性化合物。测定了叶提取物在银纳米颗粒(AgNPs)生物合成中的作用。通过紫外可见分光光度法、透射电子显微镜(TEM)、X射线衍射(XRD)和动态光散射(DLS)技术对生物合成的AgNPs进行了全面表征。此外,还研究了使用(SMAgNPs)生物合成的AgNPs对HepG2肝癌细胞的细胞毒性作用。分析了活性氧的产生、凋亡诱导、DNA损伤和自噬活性。结果清楚地表明,生物合成的银纳米颗粒通过以剂量和时间依赖性方式显著(<0.05)诱导氧化应激、细胞毒性、DNA损伤、凋亡和自噬,从而抑制HepG2的增殖。这些发现可能会促使人们将天然产物的潜力与银纳米颗粒的功效结合起来,用于制备安全、环保且有效的抗癌药物。
