Popis: | Paclitaxel loaded in liposomes modified with stearyl triphenyl phosphonium (STPP) showed improved mitochondrial colocalization and cytotoxicity in a paclitaxel resistant cell line. The improvement in cytotoxicity was not solely due to the increased accumulation of paclitaxel in mitochondria but also due to the specific toxicity of STPP towards the resistant cell line. Mechanistic studies revealed that the cytotoxicity of STPP was associated with a decrease in mitochondrial membrane potential and other hallmarks related to caspase-independent cell death (CICD). This specific toxicity of STPP towards the paclitaxel resistant cell line was also maintained in three-dimensional in vitro spheroid cultures. |
