Research progress in co-delivery of gene and chemotherapy drugs with nanocarriers for cancer therapy

Current trends in nanotechnology and RNA interference technology have made the application of nanocarriers (NCS) as a novel gene and drug delivery systems very promising for the field of multidrug resistance (MDR) cancer treatment.  Co-delivery of gene and chemotherapy drugs with NCS has a good synergistic effect compared with the traditional chemotherapy which can increase the amount of the drug distribution in target organ in order to reduce the toxic side effects thereby enhancing efficacy.  Therefore, the advent of co-delivery systems with NCS especially in the clinical treatment of MDR has had a significant impact on the cancer treatment.
