膀胱癌耐药机制的研究进展

Progress in the chemoresistance mechanisms of bladder cancer

近年来,肿瘤细胞耐药性的产生给膀胱癌的治疗和预后带来了新的挑战,因此对膀胱癌耐药机制的研究显得越来越迫切。目前发现的膀胱癌耐药机制主要包括:药物外排、上皮-间质转化、细胞自噬、微RNA调节和基因表观遗传学修饰等,其中涉及多种细胞信号转导通路。而且,不同的耐药机制可能通过相同的信号通路发生交叉联系,从而组成一个复杂的调控网络。本文就膀胱癌耐药机制研究的最新进展进行综述,以期为膀胱癌的靶向治疗提供新的思路。

In recent years, the appearance of tumor cell chemoresistance has brought new challenges to the treatment and prognosis of bladder cancer. Therefore, it is more and more urgent to study the chemoresistance mechanisms of bladder cancer. The current studies show that the chemoresistance mechanisms of bladder cancer mainly include drug efflux, epithelial-mesenchemal transformation （EMT）, cell autophagy, microRNA regulation and genetic epigenetic modification, which involves a variety of cell signal transduction pathways. Moreover, the different mechanisms of chemoresistance maybe have connections with each other by the same signaling pathways, thus forming a complex regulatory network. This paper reviews the latest progress in the study of chemoresistance mechanisms of bladder cancer, in order to provide new ideas for the targeted treatment of bladder cancer.
