Multidrug resistance (MDR) in cancer cells can significantly attenuate the response to chemotherapy and increase the likelihood of mortality. The major mechanism involved in conferring MDR is the overexpression of ATP-binding cassette (ABC) transporters, which can increase efflux of drugs from cancer cells, thereby decreasing intracellular drug concentration. Modulators of ABC transporters have the potential to augment the efficacy of anticancer drugs. This editorial highlights some major findings related to ABC transporters and current strategies to overcome MDR.
癌细胞中的多药耐药性(MDR)可显著减弱对化疗的反应并增加死亡可能性。赋予MDR的主要机制是ATP结合盒(ABC)转运蛋白的过表达,其可增加癌细胞中药物的外排,从而降低细胞内药物浓度。ABC转运蛋白调节剂有增强抗癌药物疗效的潜力。这篇社论重点介绍了与ABC转运蛋白相关的一些主要发现以及当前克服MDR的策略。
