Overcoming of doxorubicin resistance in breast cancer cells by cationic peptides
Drug resistance in tumor cells is one of the obstacles for effective cancer chemotherapy. Novel strategies for therapy of multi-drug resistant tumors include the combinations of doxorubicin with microRNA.1 Metformin2 and other prodrugs. Various molecular constructions are used to codeliver doxorubicin +metformin followed by release metformin to enhance Dox cytotoxicity through attenuating hypoxic stress and inhibition of HIF1α/Pgp expression. Small molecular inhibitors of oncoproteins and essential cell pathways are considered now as promising therapeutic agents.
