摘要
ABCG2作为一种跨膜半转运蛋白,参与了内源及外源有害物质的外排,对机体正常组织起到了保护作用,但同时也介导了对多种化疗药物的外排,引起多药耐药,使许多恶性肿瘤患者对化学药物治疗不敏感,直接影响到临床预后。本文将对ABCG2基因的单核苷酸多态性(SNP)、ABCG2与干细胞和酪氨酸激酶抑制剂(TKI)之间的关系的一些研究进展做简要介绍,同时还对ABCG2与恶性血液病耐药相关性的临床研究结果做回顾性分析,从中可以看出目前研究中存在的问题及未来的研究方向。
ABCG2, a half-transporter concerning with the endo and exon-toxin-efflux, plays an important role in protecting the normal tissues from the toxin-hurt as well as mediating the multidrug resistance, because many of the chemotherapeutic drugs are the substrate of ABCG2. In this paper, the advance of research about this genes single nucleotide polymorphisms (SNPs) was explained concisely. The relationship among ABCG2, the stem cells and the tyrosine kinase inhibitor (TKI) was reviewed. The research about drug resistance related-progress in hematologic malignancies was analyzed retrospectively and the present problems and the perspective in the future were discussed.
