In this study, we aimed to investigate whether the combination therapy of pomegranate extract and silver nanoparticle is effective on MCF-7 cell culture. The pomegranate extract was mixed and incubated with silver nitrate for the microwave assisted green synthesized of silver nanoparticle. Obtained nanoparticles were investigated using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), UV-vis, Field Emission Scanning Electron Microscopy (FESEM), and Transmission Electron Microscopy (TEM) methods The spectroscopic and morphological studies of the monodisperse Ag NPs which have particle size of 15.4nm indicate the highly crystalline form, well dispersity, and colloidally stable NPs. After fully characterization of prepared nanoparticles, the effectiveness of Ag NPs was determined by evaluating cell viability, nuclear degradation and cell cycle parameters. The results obtained demonstrate that biosynthesized Ag NPs can inhibit the proliferation of human breast cancer cell line MCF-7 in the IC50 at a dose of 12.85μg/mL and inhibit the proliferation of Ag NPs against anti-growth arresting MCF-7 cell line. This case demonstrates that it may exert its proliferative effect by reducing DNA synthesis and apoptosis-inducing cell cycle stages.
在这项研究中,我们旨在探讨石榴提取物和银纳米粒子的联合治疗是否对 MCF-7 细胞培养有效。将石榴提取物混合并与硝酸银孵育,通过微波辅助绿色合成银纳米粒子。使用 X 射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、紫外-可见分光光度法、场发射扫描电子显微镜(FESEM)和透射电子显微镜(TEM)方法研究了获得的纳米粒子。粒径为 15.4nm 的单分散 Ag NPs 的光谱和形态研究表明其具有高结晶度、良好的分散性和胶体稳定性。在充分表征制备的纳米粒子后,通过评估细胞活力、核降解和细胞周期参数来确定 Ag NPs 的有效性。结果表明,生物合成的 Ag NPs 可以在 12.85μg/mL 的剂量下抑制人乳腺癌 MCF-7 细胞系的增殖,并抑制 Ag NPs 对抗生长停滞 MCF-7 细胞系的增殖。这种情况表明,它可能通过减少 DNA 合成和诱导细胞周期阶段的凋亡来发挥其增殖作用。
