Acta Neuropathol:德国科学家找到引起多种癌症的“罪魁祸首”

来自德国癌症研究中心的科学家们发现,代谢酶中的一种氨基酸被替代就是引起多种癌症的罪魁祸首。



【阻隔特定致癌突变,让癌症无法发展】来自德国癌症研究中心的科学家们发现,代谢酶中的一种氨基酸被替代就是引起多种癌症的罪魁祸首

因此,德国癌症研究所联合海德堡大学医院,拜耳公司共同开发出可以阻止酶改变的合成物,并对小鼠进行了试验,观察该合成物的预想效果。

许多恶性肿瘤发展都是单个细胞基因改变的结果。这些基因突变往往导致蛋白质改变,为细胞提供刺激其生长的新物质。其中一个最典型的例子就是与某些恶性脑瘤有关的IDH1酶。

科学家注意到柠檬酸脱氢酶(IDH)中的突变总是发生在酶的氨基酸链特定位置,这种替代致使促进癌细胞生长的代谢产物在细胞中不断积累。

研究人员表示:“也正是这一发现使我们有了一些新的想法,如果我们在这一特定位置安置抑制柠檬酸脱氢酶突变的物质,是否可以阻止柠檬酸脱氢酶突变。此次研究的目的是是开发一种在不影响健康酶功能的条件下,可以有效阻止特定酶突变的药物。”

经过反复研究,来自德国癌症研究中心的科学家们开发了一种名为BAY1436032的合成物,对恶性脑瘤和白血病小鼠进行了实验室试验,多次试验都取得了全面成功,进一步证明了这种药物的安全性和有效性,目前,大规模的临床试验正在进行中。
