摘要

由于纳米粒子在生物医学方面的应用,以绿色为媒介合成的纳米粒子在纳米技术领域大有可为。本研究介绍了利用薇甘菊叶提取物合成银纳米粒子(AgNPs)及其抗癌功能活性。利用紫外可见光谱(UV-Vis)确认了 AgNPs 的合成,紫外可见光谱在 459 纳米处显示出吸收带。通过傅立叶变换红外光谱(FT-IR)中吸收带的移动,证实了薇甘菊叶提取物中具有还原剂和封端剂功能的生物活性化合物。扫描电子显微镜(SEM)和透射电子显微镜(TEM)研究分别验证了 AgNPs 的球形形状和大小。能量色散光谱(EDS)分析显示了银元素的存在。X 射线衍射分析 (XRD) 证实了 AgNPs 的结晶性质。AgNPs 能有效诱导细胞毒性,并以剂量依赖的方式阻止 A549 细胞集落的形成。用 AgNPs 处理 A549 细胞也会增加 DNA 损伤,同时导致脂质过氧化升高,谷胱甘肽(GSH)、谷胱甘肽转移酶(GST)和超氧化物歧化酶(SOD)等抗氧化酶减少。AgNPs处理后,A549细胞中促凋亡基因的mRNA表达水平和caspases活性显著升高,而抗凋亡基因的表达水平则下调。我们的研究表明,合成的 AgNPs 可能以细胞凋亡途径为靶点,具有治疗癌症的潜力。

Mikania micrantha silver nanoparticles exhibit anticancer activities against human lung adenocarcinoma via caspase-mediated apoptotic cell death.

Green-mediated synthesis of nanoparticles has earned a promising role in the area of nanotechnology due to their biomedical applications. This study describes the synthesis of silver nanoparticles (AgNPs) using Mikania micrantha leaf extract and its functional activities against cancer. The synthesis of AgNPs was confirmed using Ultraviolet-Visible (UV-Vis) spectrum that exhibited an absorption band at 459 nm. The bioactive compounds of M. micrantha leaf extract that functioned as reducing and capping agents were confirmed by a shift in the absorption bands in Fourier Transform Infra-red Spectroscopy (FT-IR). Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies validated the spherical shape and size of AgNPs, respectively. Energy Dispersive Spectroscopy (EDS) analysis revealed the presence of elemental silver. The crystalline nature of AgNPs was confirmed by the X-ray Diffraction Analysis (XRD). AgNPs effectively induced cytotoxicity and prevented A549 cell colony formation in a dose-dependent manner. Treatment of A549 cells with AgNPs also increased DNA damage, which was coupled with elevated lipid peroxidation and decreased antioxidant enzymes such as glutathione (GSH), glutathione-s-transferase (GST), and superoxide dismutase (SOD). Following AgNPs treatment, the mRNA expression levels of the pro-apoptotic genes as well as the activities of caspases were significantly elevated in A549 cells while the expression levels of anti-apoptotic genes were downregulated. Our study demonstrates the potential of the synthesised AgNPs for cancer therapy possibly targeting the apoptotic pathway.

期刊介绍: Artificial Cells, Nanomedicine and Biotechnology covers the frontiers of interdisciplinary research and application, combining artificial cells, nanotechnology, nanobiotechnology, biotechnology, molecular biology, bioencapsulation, novel carriers, stem cells and tissue engineering. Emphasis is on basic research, applied research, and clinical and industrial applications of the following topics:artificial cellsblood substitutes and oxygen therapeuticsnanotechnology, nanobiotecnology, nanomedicinetissue engineeringstem cellsbioencapsulationmicroencapsulation and nanoencapsulationmicroparticles and nanoparticlesliposomescell therapy and gene therapyenzyme therapydrug delivery systemsbiodegradable and biocompatible polymers for scaffolds and carriersbiosensorsimmobilized enzymes and their usesother biotechnological and nanobiotechnological approachesRapid progress in modern research cannot be carried out in isolation and is based on the combined use of the different novel approaches. The interdisciplinary research involving novel approaches, as discussed above, has revolutionized this field resulting in rapid developments. This journal serves to bring these different, modern and futuristic approaches together for the academic, clinical and industrial communities to allow for even greater developments of this highly interdisciplinary area.
