Abstract
Breast and prostate cancers are prevalent in women and men, respectively. The process of metastasis plays a crucial role in cancer advancement. Herein, two distinct forms of gold nanoparticles (GNP) were prepared and modified with bovine serum albumin (BSA) to create gold nanorods-BSA (GNR-BSA) and gold nanospheres-BSA (GNS-BSA). Various aspects of biological interactions of these nanoparticles with two prostate cancer cell lines (DU-145 and PC-3) and a breast cancer cell line (MDA-MB-231) have been investigated. The cell viability of DU-145 and PC-3 ranged from 17 to 95% across concentrations of 0.55 to 34.5 µg/mL and for MDA-MB-231 ranged from 17 to 85%. GNS-BSA exhibited no significant cytotoxicity against the cancer cell lines. Regarding cellular uptake, GNR-BSA demonstrated uptake rates of 10%, 14%, and 5% for DU-145, PC-3, and MDA-MB-231 cell lines, respectively, while GNS-BSA showed uptake of less than 0.4% for all the cell lines investigated. Notably, GNR-BSA significantly impeded the cellular migration of DU-145 and PC-3 cells over 48 h (hr) and MDA-MB-231 cells over 24 h compared to controls. GNS-BSA inhibited cell migration over 48 h (hr) for DU-145 and over 24 h for PC-3 and MDA-MB-231. Adhesion assay showed a moderate reduction of PC-3 adhesion ability (\(\sim\) 20%) by GNS-BSA, while a minimum effect was observed on DU-145 (\(\sim\) 5%). GNR-BSA has minimally affected the adhesion ability of both PC-3 (\(\sim\) 8%) and DU-145 (\(\sim\) 13%), and no adhesion ability reduction was observed on MDA-MB-231 by both GNR-BSA or GNS-BSA. This study suggests that GNP-BSA could be promising potential agents for combating cancer and inhibiting cellular invasion, and they could serve as promising platforms for drug delivery.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
