ABSTRACT
Chemotherapy has been ineffective in cancer treatment, and efficient delivery of chemotherapeutic agents remains a challenge. In this study, we developed a doxorubicin-loaded shilajit-based nanocarrier (SHN-Dox) using a nanoprecipitation method to enhance Dox uptake into breast cancer cells (MCF-7 and ZR-75-1). After confirmation of the physicochemical properties of the nanocarriers, the cytotoxic and pro-apoptotic effects of SHN-Dox and the production of reactive oxygen species (ROS) were evaluated on breast cancer cells. SHN-Dox showed a spherical shape with a size of 244 nm and a sustainable release profile of Dox. It exhibited high cytotoxicity against MCF-7 and ZR-75-1 cells, effectively inducing DNA fragmentation in these cells. After 24 h of treatment, SHN-Dox increased the apoptosis rate in MCF-7 cells and raised ROS levels. Therefore, SHN-Dox is a promising carrier that might reduce the side effects of Dox on healthy cells and provide a new strategy for clinical cancer treatment.
