Int J Biol Sci:FePt / GO纳米片抑制人体非小细胞肺癌细胞的增殖,增强放射增敏作用并诱导其自噬

2019-06-13 不详 网络

随着纳米技术的进步,各种纳米复合材料已应用于癌症的诊断和治疗。我们合成了FePt纳米粒子,它们组装在氧化石墨烯(GO)的表面上。这些新型FePt / GO纳米片同时作为化疗药物并增强放射敏感性。本研究采用透射电子显微镜,动态光散射,X射线光电子能谱和傅立叶变换红外光谱对FePt/GO纳米片(NSs)的表面形貌和化学组成进行了表征。通过细胞计数试剂盒-8测定法评估它们在各种癌症和正常细胞中的细胞毒性

随着纳米技术的进步,各种纳米复合材料已应用于癌症的诊断和治疗。我们合成了FePt纳米粒子,它们组装在氧化石墨烯(GO)的表面上。这些新型FePt / GO纳米片同时作为化疗药物并增强放射敏感性。

本研究采用透射电子显微镜,动态光散射,X射线光电子能谱和傅立叶变换红外光谱对FePt/GO纳米片(NSs)的表面形貌和化学组成进行了表征。通过细胞计数试剂盒-8测定法评估它们在各种癌症和正常细胞中的细胞毒性,并通过集落形成测定法测定它们对放射增敏作用的影响。为了探索潜在的机制,我们测量了细胞内活性氧水平和自噬形成。使用Monodansylcadaverine染色,Western印迹和超微结构分析来评估自噬。

结果表明,FePt/GO NSs不仅选择性地抑制癌细胞的增殖,而且还增加了它们的放射增敏作用。此外,FePt/GO NSs诱导自噬,这可能导致促进放射治疗的敏感性。

总之,具有良好的安全性和有效性,FePt/GO NSs安全有效地抑制增殖,增强放射增敏作用并诱导人非小细胞肺癌细胞的自噬。它们具有治疗肺癌的潜力。
