Oncotarget :EZH2过度表达和伤口渗出液使膀胱癌细胞化疗敏感性变差

2017-07-12 Emma MedSci原创

膀胱癌是发生在膀胱黏膜上的恶性肿瘤,是泌尿系统最常见的恶性肿瘤,是全身十大常见肿瘤之一,也占我国泌尿生殖系肿瘤发病率的第一位。

膀胱癌是发生在膀胱黏膜上的恶性肿瘤,是泌尿系统最常见的恶性肿瘤,是全身十大常见肿瘤之一,也占我国泌尿生殖系肿瘤发病率的第一位。组蛋白甲基化转移酶EZH2与组蛋白甲基化修饰有关,在细胞的生长发育中起到重要作用,也是在肿瘤发生中较早受到重视的转录因子。研究发现它在多种肿瘤及其细胞系中高表达。发表于Oncotarget的一篇文章中,研究人员通过胶滴肿瘤药敏检测技术(CD-DST),调查了EZH2(组蛋白甲基化转移酶)和WF(伤口渗出液)对T24膀胱癌细胞的化疗敏感性的影响,结果显示EZH2的过度表达和手术诱发的WF增加了膀胱癌细胞对所研究的化疗药物的耐药性。研究人员将EZH2表达水平不同的T24膀胱癌细胞与膀胱癌患者术后WF共培养,膀胱癌细胞的存活率用于显示药物的化疗效果。使用的化疗药物为吉西他滨和顺铂。其中,EZH2敲除增加了肿瘤细胞对吉西他滨和顺铂的化疗敏感性,EZH2过表达降低了化疗敏感性,而与WF共培养也降低了肿瘤细胞的化疗敏感性。原始出处:Bi H, et al.
