Bio-fabrication of gold nanoparticles (AuNPs) has several advantages like biocompatibility, less toxicity, and eco-friendly in nature over their chemical and physical methods. Currently, the authors fabricated AuNPs using aqueous root extract of Momordica dioica (M. dioica) and explored their anticancer application with mechanistic approaches. Different biophysical techniques such as UV-visible spectroscopy, Fourier transform infrared, X-ray diffraction, transmission electron microscopy, selected area electron diffraction, and dynamic light scattering were employed for AuNPs characterisation. The synthesised AuNPs were mono-dispersed, crystalline in nature, anionic surface (-23.9 mV), and spherical particle of an average diameter of 9.4 nm. In addition, the AuNPs were stable in buffers solutions and also biocompatible towards normal human cells (human vascular endothelial cells and human lung cells). The AuNPs were exhibited anticancer activity against different cancer cell lines such as human breast cancer cells, human cervical cancer cells (HeLa) and human lung cancer cells. Further, the pro-apoptotic genes such as Bcl2 were down-regulated and BAX, Caspase-3, -8, and -9 were up-regulated in HeLa cells as compared to untreated cells. Annexin-V-FITC assay results showed that the AuNPs were induced apoptosis by accumulation of intracellular reactive oxygen species. To their knowledge, this is the first report on the synthesis of bioactive metal nanoparticles from M. dioica and it may open up new avenues in therapeutic applications.

苦瓜介导的金纳米粒子诱导宫颈癌细胞的外在和内在细胞凋亡。

与化学和物理方法相比,金纳米粒子 (AuNPs) 的生物制造具有生物相容性、毒性小和生态友好等优点。目前,作者使用苦瓜(M. dioica)的水根提取物制造了AuNPs,并通过机械方法探索了它们的抗癌应用。不同的生物物理技术,如紫外-可见光谱、傅里叶变换红外、X 射线衍射、透射电子显微镜、选区电子衍射和动态光散射用于 AuNPs 的表征。合成的AuNPs是单分散的、晶体性质的、阴离子表面(-23.9 mV)和平均直径为9.4 nm的球形颗粒。此外,AuNPs 在缓冲溶液中是稳定的,并且对正常人体细胞(人血管内皮细胞和人肺细胞)也具有生物相容性。AuNPs对人乳腺癌细胞、人宫颈癌细胞(HeLa)和人肺癌细胞等不同癌细胞系表现出抗癌活性。此外,与未经处理的细胞相比,HeLa 细胞中的促凋亡基因如 Bcl2 下调,BAX、Caspase-3、-8 和 -9 上调。Annexin-V-FITC检测结果表明,AuNPs通过细胞内活性氧的积累诱导细胞凋亡。据他们所知,这是第一份关于从 M. dioica 合成生物活性金属纳米粒子的报告,它可能会开辟治疗应用的新途径。AuNPs对人乳腺癌细胞、人宫颈癌细胞(HeLa)和人肺癌细胞等不同癌细胞系表现出抗癌活性。此外,与未经处理的细胞相比,HeLa 细胞中的促凋亡基因如 Bcl2 下调,BAX、Caspase-3、-8 和 -9 上调。Annexin-V-FITC检测结果表明,AuNPs通过细胞内活性氧的积累诱导细胞凋亡。据他们所知,这是第一份关于从 M. dioica 合成生物活性金属纳米粒子的报告,它可能会开辟治疗应用的新途径。AuNPs对人乳腺癌细胞、人宫颈癌细胞(HeLa)和人肺癌细胞等不同癌细胞系表现出抗癌活性。此外,与未经处理的细胞相比,HeLa 细胞中的促凋亡基因如 Bcl2 下调,BAX、Caspase-3、-8 和 -9 上调。Annexin-V-FITC检测结果表明,AuNPs通过细胞内活性氧的积累诱导细胞凋亡。据他们所知,这是第一份关于从 M. dioica 合成生物活性金属纳米粒子的报告,它可能会开辟治疗应用的新途径。与未处理的细胞相比,HeLa 细胞中的促凋亡基因如 Bcl2 下调,BAX、Caspase-3、-8 和 -9 上调。Annexin-V-FITC检测结果表明,AuNPs通过细胞内活性氧的积累诱导细胞凋亡。据他们所知,这是第一份关于从 M. dioica 合成生物活性金属纳米粒子的报告,它可能会开辟治疗应用的新途径。与未处理的细胞相比,HeLa 细胞中的促凋亡基因如 Bcl2 下调,BAX、Caspase-3、-8 和 -9 上调。Annexin-V-FITC检测结果表明,AuNPs通过细胞内活性氧的积累诱导细胞凋亡。据他们所知,这是第一份关于从 M. dioica 合成生物活性金属纳米粒子的报告,它可能会开辟治疗应用的新途径。
