日前,加拿大多伦多大学等机构的研究人员揭开了一种与疾病有关的重要蛋白的神秘面纱,这一发现将有助于研发治疗癌症,囊肿性纤维化以及其它疾病的新方法。

在这项刊登在《Nature Chemical Biology》杂志上的研究中,科学家们首次揭示了ATP结合盒式转运蛋白(ATP-binding cassette (ABC) transporter proteins,也称为ABC转运蛋白)的作用路线图。

这类蛋白对于每个细胞来说都是重要组件,是一类能利用ATP水解能量,逆浓度方向将一系列化合物转运通过膜结构的膜蛋白。这一类蛋白能转运离子,糖,氨基酸,维生素,多肽,多糖,激素,脂类及生物异源物质。近年来,许多研究涉及到如何逆转由ABC转运蛋白引起的肿瘤多药耐药性。近年来,许多研究都涉及到如何逆转由ABC转运蛋白引起的肿瘤多药耐药性。

科学家们一直致力于解析这种蛋白如何完成功能,以及与其他蛋白相互交流的,研究人员利用酵母双杂交(MYTH)技术解答了这一难题,他们发现了这些转运蛋白如何与细胞中其他关键组件如何相互作用的机制。

研究人员表示,细胞系统十分复杂,要了解某些疾病如何发生的,以及最好的治疗方案,我们需要切实掌握单个成分如何结合在一起的。

ABC转运蛋白作为细胞的看门人,能为细胞保存养分,并排出毒素。如果这些蛋白不能正常工作,那么就会导致疾病发生,如囊性纤维化,年龄相关性的黄斑变性,Tangier病,Dubin-Johnson 综合征等。 而且ABC转运蛋白也会导致癌细胞对化疗药物产生抗性,治疗效果差。

研究人员总结道,发现ABC转运蛋白如何影响癌症和其他疾病的作用机制,这将有助于研发更好的,更有针对性的药物。这是这项研究真正的重大意义。

癌症干细胞标志蛋白被发现

  治疗癌症如果不把癌症干细胞彻底清除,癌症很容易复发和转移。日本京都大学的研究人员说,他们找到了癌症干细胞含有的一种标志蛋白,有望对癌细胞做到“斩草除根”。   京都大学消化内科教授千叶勉领导的研究小组在研究中注意到消化道中的一种蛋白质Dclk1,他们分析了罹患大肠癌的实验鼠,发现含这种蛋白质的细胞会在较长一段时间内持续产生癌细胞。他们通过基因操作成功地有选择地清除了含Dclk1蛋白质的细胞,

Cell Immunity:一种蛋白质有助控制免疫系统功能

日本一个研究团队报告说,他们发现一种蛋白质与调节细胞内钙浓度相关,是抑制性T细胞成熟所必需的,如实现对这种蛋白质分子的人工控制,就有可能治疗干燥综合征、多发性硬化症等自体免疫疾病。 健康人体免疫系统能区别自体与外来物质,在攻击入侵的细菌、病毒等病原体的同时,避免攻击自身组织。但是如果免疫反应过度,免疫系统就会攻击正常的细胞和组织,导致过敏和自体免疫疾病等。因此,何时激活或抑制免疫系统非常重要。
