一项最新的研究显示,一种新的定位方法可以靶向癌症相关的蛋白质, 这项研究发表在《自然》杂志中。在研究报告中,科学家开发的小分子抑制剂可以绑定一种酶上,这种酶控制着p53肿瘤抑制基因蛋白质的稳定性。这种失活使p53打开,在不断增长的癌细胞中安装刹车。

大多数的癌症P53有缺陷或不活跃的,因此癌细胞可以不受控制的疯长,尽管P53在癌症中发挥着重要的作用,但是很多靶向p53的研究都走向了死胡同。为了解决这个问题,研究人员着眼于泛素蛋白酶体系统,它负责监管蛋白质数量,其中也包括p53。

在此次研究中,科学人员们关注酶系统,研究人员能够展示两种抑制剂如何链接独特的结合位点酶,这就会带来一连串的影响,最终激活p53。

此次研究由英国癌症研究中心,牛津大学医学研究中心和剑桥大学医学研究委员会分子生物学实验室的研究人员们共同进行。来自英国癌症研究中心的研究人员表示:“我们的研究表示,这一方法可以针对这些无药可治的蛋白质,专门控制它们的酶。我们可以详细解读这些酶的三维结构和他们的潜在目标,为全新的治疗起点,开发药物和蛋白质控制打开了一扇新的大门。

来自牛津大学医学研究中心的科学家补充道:“通过扩展药物研究的方法,我们希望打开驱动癌症的其他蛋白质的方法,并解决引起其他慢性疾病的问题,如神经退化和免疫障碍。”

Nature:促进肿瘤生长的机制:循环乳酸盐

肿瘤从他们所在的患者身体获得能量和生长生存所必需的营养。虽然这些营养素主要由循环血液供应,但我们对这些营养物质的了解以及肿瘤的使用方式是不完整的。识别肿瘤营养物质及其使用方法可能揭示了癌症治疗的新方法。新泽西州罗茨格癌症研究所和普林斯顿大学研究人员的研究令人惊奇地发现,循环乳酸而不是葡萄糖是肿瘤和大多数正常组织的代谢燃料来源。循环乳酸盐用于产生能量,释放葡萄糖以支持对肿瘤生长重要的代谢功能。
