Sci Rep:治疗顺铂诱导的听力损失的新靶标

2021-04-30 AlexYang MedSci原创

G蛋白信号调节因子(RGS)提高了G蛋白的GTP酶活性,使G蛋白偶联受体(GPCRs)引发的信号快速终止。几个GPCRs的激活,包括大麻素受体2(CB2R)和腺苷A1受体(A1AR),可以预防噪音和药

G蛋白信号调节因子(RGS)提高了G蛋白的GTP酶活性,使G蛋白偶联受体(GPCRs)引发的信号快速终止。几个GPCRs的激活,包括大麻素受体2(CB2R)和腺苷A1受体(A1AR),可以预防噪音和药物引起的耳毒性。

顺铂是一种用于治疗各种实体瘤的抗癌剂,在实验动物和高比例接受治疗的癌症患者中产生永久性听力损失。

最近,有研究人员表明顺铂会诱导RGS17基因的表达,并增加RGS17蛋白的水平,该蛋白在很大比例的听力损失中存在作用。敲除RGS17可以抑制顺铂诱导的雄性Wistar大鼠的听力损失,而单独过表达RGS17则引起听力损失。此外,RGS17和CB2R对彼此的表达有负调控作用。

RGS17敲除抑制了顺铂介导的耳蜗细胞凋亡

最后,研究人员指出,RGS17通过解除细胞保护性GPCR与正常G蛋白的相互作用来介导顺铂的耳毒性,从而减轻这些受体的内源性配体的耳保护贡献。因此,RGS17代表了顺铂耳毒性的一个新介导因子,也是治疗听力损失的一个潜在治疗靶标
