Siddiqui Cell Biochemistry and Function ABSTRACTDue to their exceptional physicochemical features, green synthesized silver nanoparticles (AgNPs) have been of considerable interest in cancer treatment. In the present study, for the first time, we aimed to green synthesize AgNPs from Euphorbia retusa and explore their anticancer potential on human breast cancer (MCF‐7) cells. First, the green synthesized AgNPs (EU‐AgNPs) were well characterized by UV–visible spectroscopy, Fourier transmission infrared (FTIR) spectrum, XRD, scanning and transmission electron microscopy (SEM and TEM), and EDX techniques. The characterization data exhibited that EU‐AgNPs were spherical in shape and crystalline in nature with an average size of 17.8 nm. FTIR results established the presence of active metabolites in EU‐AgNPs. Second, the anticancer effect of EU‐AgNPs was evaluated against MCF‐7 cells by MTT and neutral red uptake (NRU) assays. Moreover, morphological changes, ROS production, MMP, and apoptotic marker genes were also studied upon exposure to cytotoxic doses of EU‐AgNPs. Our results showed that EU‐AgNPs induce cytotoxicity in a concentration‐dependent manner, with an IC50 value of 40 μg/mL. Morphological changes in MCF‐7 cells exposed to EU‐AgNPs also confirm their cytotoxic effects. Increased ROS and decreased MMP levels revealed that EU‐AgNPs induced oxidative stress and mitochondrial membrane dysfunction. Moreover, ROS–mediated apoptosis was confirmed by elevated levels of proapoptotic marker genes (p53, Bax, caspase‐3, and caspase‐9) and reduced levels of an antiapoptotic gene (Bcl‐2). Altogether, these findings suggested that EU‐AgNPs could induce potential anticancer effects through ROS–mediated apoptosis in MCF‐7 cells. 10.1002/cbf.4113 http://onlinelibrary.wiley.com/termsAndConditions#vor |
