In the current experimental work, silver chloride nanoparticles (AgClNPs) were fabricated using Onopordum acanthium L. extract and their apoptotic and cytotoxicity properties on breast cancer MDA_MB232 and normal human embryonic kidney 293 (HEK293) cell lines were also evaluated. AgClNPs formation was determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) profile. Effect of fabricated AgClNPs on MDA_MB232 and HEK293 cells viability was performed using colorimetric MTT assay. Alterations in the mRNA expression levels of CAD and Bax genes in MDA-MB-232 cells were done using quantitative real-time reverse transcription-PCR (qRT-PCR) method. Subsequently, apoptotic properties were determined using flow cytometry and fluorescence microscopy studies. According to MTT results, the AgCLNPs have a significant dose-dependent lethal activity on MDA_MB232 compared to HEK293 cell lines. Quantitative real-time reverse transcription-PCR (qRT-PCR) results have also shown that AgClNPs could up-regulate the apoptotic Bax and CAD gene expressions in the MDA_MB232 cells. Additionally, apoptotic assessment was performed by cell cycle analysis, annexin V/PI test, Hoechst 33258 dye, acridine orange, and ethidium bromide (AO/EB) staining along with the detection of the reactive oxygen species (ROS) generation. Our results suggest that novel silver chloride nanoparticles fabricated by Onopordum acanthium L. extract can display some promising cytotoxic properties through inducing apoptosis pathway.
