Abstract The anticancer activity of silver nanoparticles (AgNPs) is well known to be synthesized using green-synthesized methods, although its mechanism of action is not understood fully. Moringa oleifera leaves were used as reducing and stabilizing agents to synthesize AgNPs. Green-synthesized AgNPs were characterized using ultraviolet-visible spectroscopy, dynamic light scattering, transmission electronic microscopy, scanning electronic microscopy, Fourier transform infrared, and energy-dispersive X-ray spectroscopy analyses. The synthesized nanoparticles were then characterized by their anticancer properties by performing a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The real-time polymerase chain reaction was used to check the expression levels of the four genes (β-catenin, adenomatous polyposis coli (APC), and lipoprotein receptor-related proteins 5 and 6 (LRP5/6)). The synthesized nanoparticles were 25 nm on average and spherical in shape and aggregated form. Noteworthy cytotoxicity is how green-synthesized M. oleifera–AgNPs were observed in comparison with the M. oleifera leaf extract against a cancerous cell line. The M. oleifera–AgNPs decreased the expression of CTNNB1 and LRP6 genes, while the LRP5 gene expression increased in both cell lines. With treatment, the APC gene expression decreased in SW480 but increased in HTC116. Our results imply that AgNPs synthesized by M. oleifera extract could be an ideal strategy to combat colon cancer.

绿色合成辣木-AgNPs对人结肠癌细胞的抗结肠癌活性

摘要 众所周知,银纳米粒子 (AgNPs) 的抗癌活性是使用绿色合成方法合成的,尽管其作用机制尚不完全清楚。辣木叶被用作合成AgNPs的还原剂和稳定剂。使用紫外-可见光谱、动态光散射、透射电子显微镜、扫描电子显微镜、傅里叶变换红外和能量色散 X 射线光谱分析对绿色合成的 AgNPs 进行了表征。然后通过进行 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑测定来表征合成的纳米粒子的抗癌特性。采用实时聚合酶链反应检测四种基因(β-catenin、腺瘤性结肠息肉病(APC)、和脂蛋白受体相关蛋白 5 和 6 (LRP5/6))。合成的纳米粒子平均为 25 nm,呈球形和聚集形式。值得注意的是,与 M. oleifera 叶提取物对抗癌细胞系相比,绿色合成的 M. oleifera–AgNPs 是如何观察到的。M. oleifera-AgNPs 降低了 CTNNB1 和 LRP6 基因的表达,而 LRP5 基因表达在两种细胞系中都增加了。处理后,APC 基因表达在 SW480 中降低,但在 HTC116 中增加。我们的研究结果表明,由 M. oleifera 提取物合成的 AgNPs 可能是对抗结肠癌的理想策略。与 M. oleifera 叶提取物对抗癌细胞系相比,观察到 oleifera-AgNPs。M. oleifera-AgNPs 降低了 CTNNB1 和 LRP6 基因的表达,而 LRP5 基因表达在两种细胞系中都增加了。处理后,APC 基因表达在 SW480 中降低,但在 HTC116 中增加。我们的研究结果表明,由 M. oleifera 提取物合成的 AgNPs 可能是对抗结肠癌的理想策略。与 M. oleifera 叶提取物对抗癌细胞系相比,观察到 oleifera-AgNPs。M. oleifera-AgNPs 降低了 CTNNB1 和 LRP6 基因的表达,而 LRP5 基因表达在两种细胞系中都增加了。处理后,APC 基因表达在 SW480 中降低,但在 HTC116 中增加。我们的研究结果表明,由 M. oleifera 提取物合成的 AgNPs 可能是对抗结肠癌的理想策略。
