Abstract |
Current cancer chemotherapies commonly suffer from non-specificity, drug resistance, poor bioavailability and narrow therapeutic indices. To achieve the optimum drug efficacy, we designed a polymeric drug delivery system for targeted intracellular delivery of a clinically-approved, water-soluble anticancer drug, gemcitabine hydrochloride (GEM). We utilised the unique ability of a cyclic pentapeptide cRGDfK to specifically target αvβ3 integrin receptors that are over-expressed on SKOV-3 human ovarian cancer cells. This significantly increased the effective intracellular drug concentration even at low doses, thereby remarkably improving the chemotherapeutic potential of GEM. cRGDfK-conjugated, GEM-loaded nanoparticles reduced the nonspecific hemolytic cytotoxicity of the drug, simultaneously influencing intracellular processes such as mitochondrial membrane potential (DΨm), reactive oxygen species (ROS) levels and apoptosis, thereby favourably influencing drug anti-proliferative efficacy. |
