摘 要:顺铂广泛用于治疗多种恶性肿瘤,但在治疗过程中容易产生耐药。顺铂耐药被报道与蛋白泛素化密切相关,蛋白泛素化由3类酶即泛素活化酶(E1)、泛素结合酶(E2)和泛素化连接酶(E3)催化,其中E3在泛素化过程中可通过识别与调控底物表达来影响顺铂药物敏感性。该文通过对E3调控底物影响顺铂药物敏感性的分子机制进行综述,为恶性肿瘤的顺铂耐药逆转提供新思路。 |

Abstract:Cisplatin is widely used in the treatment of different types of malignancy,but drug-resistant is frequently occurs in the treatment course.Recently cisplatin resistance is reported to be closely related to protein ubiquitination,which is catalyzed by three kinds of enzymes,including ubiquitin activators(E1),ubiquitin binding enzymes(E2) and ubiquitin ligases(E3). E3 can affect the drug sensitivity of cisplatin by regulating and recognizing substrate in the ubiquitination process. The molecular mechanisms of ubiquitin ligases regulating substrates related to cisplatin resistance are summarized in this article. |
