Abstract

BACKGROUND

Certainly, there is a demand for stronger recognition of how nanoparticles can move through the cell membrane. Prostate cancer is one of the forcing sources of cancer-relevant deaths among men.

AIM OF THE WORK

The current research studied the power of prostate cancer cells to uptake a ternary nanocomposite TNT/CuFeO/Zn-Fe mixed metal oxides (MMO).

METHODOLOGY

The nanocomposite was synthesized by a chemical method and characterized by a High-resolution transmission electron microscope, Field emission scanning electron microscope, X-ray diffraction, Fourier transmission infra-red, X-ray photoelectron spectroscopy, dynamic light scattering. Besides, it was implemented as an inorganic anticancer agent versus Prostate cancer PC-3 cells.

RESULTS

The results revealed cellular uptake validity, cell viability reduction, ultra-structures alterations, morphological changes and membrane damage of PC-3 cells.

CONCLUSION

The prepared ternary nanocomposite was highly uptake by PC-3 cells and possessed cytotoxicity that was dose and time-dependent. To conclude, the study offered the potential of the investigated ternary nanocomposite as a promising prostate anticancer agent.

摘要

背景

纳米颗粒如何穿透细胞膜,这一点需要得到更多的关注。前列腺癌是导致男性癌症相关死亡的主要原因之一。

目的

本研究旨在探讨前列腺癌细胞摄取三元纳米复合材料 TNT/CuFeO/Zn-Fe 混合金属氧化物(MMO)的能力。

方法

采用化学方法合成纳米复合材料,并通过高分辨率透射电子显微镜、场发射扫描电子显微镜、X 射线衍射、傅里叶变换红外光谱、X 射线光电子能谱、动态光散射对其进行表征。此外,还将其作为一种无机抗癌剂用于前列腺癌 PC-3 细胞。

结果

结果表明,该三元纳米复合材料具有细胞摄取有效性、细胞活力降低、超微结构改变、形态变化和细胞膜损伤等作用。

结论

研究表明,所制备的三元纳米复合材料可被 PC-3 细胞大量摄取,并具有剂量和时间依赖性的细胞毒性。综上所述,该研究为所研究的三元纳米复合材料作为一种有前途的前列腺癌抗癌剂提供了依据。
