Oncotarget:生物标志物预测脑癌治疗情况和效果

2014-07-11 佚名 生物谷

2014年7月10日讯 /生物谷BIOON/--近日,加州大学医学院圣地亚哥分校医学院研究人员发现了一种新的生物标志物,能预测是否胶质母细胞瘤(原发性脑肿瘤中最常见的形式)将回应化疗。该研究结果发表在Oncotarget杂志上。 加州大学圣地亚哥科圣地亚哥分校医学院医学博士Clark C. Chen说:每一个胶质母细胞瘤诊断病人都接受替莫唑胺化疗治疗,大约15%的患者获得持久的治疗益处。williamhill asia 需

2014年7月10日讯 /生物谷BIOON/--近日,加州大学医学院圣地亚哥分校医学院研究人员发现了一种新的生物标志物,能预测是否胶质母细胞瘤(原发性脑肿瘤中最常见的形式)将回应化疗。该研究结果发表在Oncotarget杂志上。

加州大学圣地亚哥科圣地亚哥分校医学院医学博士Clark C. Chen说:每一个胶质母细胞瘤诊断病人都接受替莫唑胺化疗治疗,大约15%的患者获得持久的治疗益处。williamhill asia 需要确定哪些患者将从替莫唑胺以及其他类型的治疗中获益,因为所有治疗均涉及风险和副作用,如果没有获益的可能性,病人不应该接受治疗。

为了查明哪些患者最有可能对替莫唑胺治疗响应,研究人员研究了控制一种蛋白--甲基鸟嘌呤甲基转移酶或MGMT表达的microRNA。这种蛋白质“挫伤”替莫唑胺的杀癌效果。高水平MGMT的肿瘤都与替莫唑胺治疗效益差有关。

科学家们系统地测试人类基因组中每个microRNA,以识别哪些抑制MGMT蛋白表达。发现,调节MGMT的microRNA签名预测胶质母细胞瘤患者对替莫唑胺的反应。这些结果将导致新的诊断工具,使能够确定哪些患者将从替莫唑胺治疗获得最大受益。

在这项研究中,科学家们还发现注射了调节MGMT的microRNA到成胶质瘤细胞中,能增加对替莫唑胺治疗的敏感性。
