Sci Rep:甲基代谢中的异常甲基化关键基因是泌尿道上皮恶性肿瘤的分子病因学之一

2018-02-28 AlexYang MedSci原创

尿路上皮癌(UC)是泌尿膀胱癌中最为常见的癌症,可以引起严重的发病率和死亡率。在欧盟,大约每年有4万人因该病死亡,并且在医疗体系上,由于长久的治疗和长期的监控,能够产生巨大的花费。之前的研究表明,大量的异常的DNA甲基化在尿路上皮癌中十分流行,并且认为能够导致遗传的不稳定性。然而,该表观遗传改变在癌变过程中是怎样增加的仍旧不清楚。完整的甲基代谢在维持细胞类型特异性甲基化组上是需要的,从而保证遗传的

尿路上皮癌(UC)是泌尿膀胱癌中最为常见的癌症,可以引起严重的发病率和死亡率。在欧盟,大约每年有4万人因该病死亡,并且在医疗体系上,由于长久的治疗和长期的监控,能够产生巨大的花费。之前的研究表明,大量的异常的DNA甲基化在尿路上皮癌中十分流行,并且认为能够导致遗传的不稳定性。然而,该表观遗传改变在癌变过程中是怎样增加的仍旧不清楚。

完整的甲基代谢在维持细胞类型特异性甲基化组上是需要的,从而保证遗传的完整性和合适的细胞学功能。最近,有研究人员利用2个独立的技术来检测DNA甲基化,研究人员在早期尿路上皮恶性肿瘤中观察到了关键甲基化代谢基因ODC1、AHCY和MTHFR在5'调控区域过度甲基化。这些过度甲基化与遗传不稳定性相关。

最后,研究人员指出,甲基化代谢基因的过度甲基化在前馈循环中起作用,并且可以促进另外的一些甲基化改变,这些研究也表明了尿路上皮癌分子病因学的一个新的假设。
