A novel encapsulation approach to enhance the delivery and antitumor activity of docetaxel in breast cancer therapy.

Docetaxel (DTX) is one of the most potent anticancer drugs but its extensive side effects necessitate innovative formulations. In this study, we aimed to investigate the expression pattern of apoptotic proteins, cell cycle arrest, and apoptosis induction after treatment with encapsulated DTX in alginate-chitosan nanoparticles in both breast cancer cells (MCF-7) and peripheral blood mononuclear cells (PBMCs). The characterization of the nanoparticles revealed a spherical shape with a size <50 nm, a hydrodynamic diameter of 200 nm, a Polydispersity Index of 0.
