| Abstract: | Currently, nanotechnology and nanoparticles (NPs) are recognised due to their extensive applications in medicine and the treatment of certain diseases, including cancer. Silver NPs (AgNPs) synthesised by environmentally friendly method exhibit a high medical potential. This study was conducted to determine the cytotoxic and apoptotic effects of AgNPs synthesised from sumac (Anacardiaceae family) fruit aqueous extract (AgSu/NPs) on human breast cancer cells (MCF‐7). The anti‐proliferative effect of AgSu/NPs was determined by MTT assay. The apoptotic properties of AgSu/NPs were assessed by morphological analysis and acridine orange/propidium iodide (AO/PI) and DAPI staining. The mechanism of apoptosis induction in treated cells was investigated using molecular analysis. Overall results of morphological examination and cytotoxic assay revealed that AgSu/NPs exert a concentration‐dependent inhibitory effect on the viability of MCF‐7 cells (IC50 of ∼10 µmol/48 h). AO/PI staining confirmed the occurrence of apoptosis in cells treated with AgSu/NPs. In addition, molecular analysis demonstrated that the apoptosis in MCF‐7 cells exposed to AgSu/NPs was induced via up‐regulation of Bax and down‐regulation of Bcl‐2. These findings suggested the potential use of AgSu/NP as cytotoxic and pro‐apoptotic efficacy and its possible application in modern medicine for treating certain disorders, such as cancer.Inspec keywords: nanoparticles, silver, nanomedicine, biomedical materials, toxicology, cancer, molecular biophysics, proteins, biochemistry, cellular biophysics, nanofabricationOther keywords: Ag, Bcl‐2 down‐regulation, Bax up‐regulation, MCF‐7 cell viability, concentration‐dependent inhibitory effect, cytotoxic assay, molecular analysis, DAPI staining, acridine orange‐propidium iodide staining, morphological analysis, MTT assay, human breast cancer cells, sumac fruit aqueous extract, Anacardiaceae family, cytotoxic effects, drug delivery function, diseases, Rhus coriaria L, silver nanoparticles, antiproliferative potential, apoptotic efficacy |
