Structure and function of ABCG2-rich extracellular vesicles mediating multidrug resistance.
Multidrug resistance (MDR) is a major impediment to curative cancer chemotherapy.The ATP-Binding Cassette transporters ABCG2, ABCB1 and ABCC2 form a unique defense network against multiple structurally and functionally distinct chemotherapeutics, thereby resulting in MDR.Thus, deciphering novel mechanisms of MDR and their overcoming is a major goal
