J Cell Biol:驱动癌症转移的新机制

2015-03-05 佚名 生物谷

根据蒙特利尔神经学研究所和麦吉尔大学研究员完成的一项新的研究发现:一种在人类细胞中普遍存在的蛋白质可能是一个重要开关,能激活癌细胞转移。到目前为止,这一重要的发现在很大程度上被忽略。这一蛋白质作用的发现,显著扩展了我们对上皮癌如乳腺癌和肺癌的认识。 该研究发现了DENND2B蛋白质的功能。在儿童发育过程中,DENND2B可能对细胞的正常迁移有作用。在成人中,细胞迁移大大降低,但在癌症的情况下

根据蒙特利尔神经学研究所和麦吉尔大学研究员完成的一项新的研究发现:一种在人类细胞中普遍存在的蛋白质可能是一个重要开关,能激活癌细胞转移。到目前为止,这一重要的发现在很大程度上被忽略。这一蛋白质作用的发现,显著扩展了我们对上皮癌如乳腺癌和肺癌的认识。

该研究发现了DENND2B蛋白质的功能。在儿童发育过程中,DENND2B可能对细胞的正常迁移有作用。在成人中,细胞迁移大大降低,但在癌症的情况下,发生了不必要的细胞迁移,能促进肿瘤细胞转移到新部位。
 
DENND2B激活另一种蛋白质Rab13,Rab13是促进细胞迁移酶。到现在为止,我们还不知道Rab13如何激活启动细胞的迁移。
 
研究人员发现Rab13在许多类型的癌症特别是经常​​转移至脑部的上皮癌中异常高程度的表达。重要的是要弄清楚Rab13在细胞中哪里被开启,搞清楚它在哪里激活对于它是如何发挥作用是很重要的。研究看到DENND2B蛋白在细胞的前缘激活Rab13。
 
主要研究者McPherson博士认为Rab13或许是未来研究癌症疗法的重点。研究者将含有高水平Rab13蛋白质的乳腺癌细胞以及Rab13被人为地剔除的侵袭性​​乳腺癌细胞注入到小鼠体内。
 
在具有较低Rab13水平的乳腺癌细胞情况下,鼠体内癌症压根不生长或只能形成一个更小的肿瘤。此外,所形成的更小的肿瘤没有转移到其他组织。在这项研究之前,没有人认为, Rab13在癌症中的重要作用,McPherson博士补充说,新的研究发现将推动临床试验的开展.

Nat Cell Biol:发现促进癌症转移的关键蛋白质

想知道癌细胞如何转移嘛?近日,刊登在国际杂志Nature Cell Biology上的一篇研究论文中,来自德克萨斯大学癌症研究中心的研究人员通过研究表示,癌细胞可以适应一定的能量需求来进行扩散转移,癌症发生转移是引发癌症相关死亡的主要原因,揭示癌症转移的机理对于开发新型抗癌疗法非常关键。 研究者发现,癌细胞可以通过其“定居”的部位获取不同的能量来继续其转移活动,在研究过程中研究人员发现了一种

JCI:可促癌症转移的特殊胶原交联结构

当摩天大楼基本架构形成之后承包商们就会依据大楼结构来添加钢梁和支架,然而癌细胞也可以利用这种方式来生长,其会利用一种生物学基质来实现繁殖和扩散;近日一篇发表在国际杂志Journal of Clinical Investigation上的研究论文中,来自得克萨斯大学MD癌症研究中心的研究人员通过研究发现一种名为胶原交联结构的人类细胞支架,其可以决定肿瘤的生长及扩散能力,这种蛋白复合物的交联结构可

Nature:癌细胞的“糖衣炮弹”信号

细胞的细胞膜是细胞与外界环境交换信息的一个信号界面,这一结构由脂质和蛋白组成,后者包含有跨膜蛋白和脂质蛋白,通过共价键进一步修饰,添加糖能形成糖蛋白。癌细胞比健康细胞糖蛋白的水平更高,如mucin-1,个别糖蛋白还可以传递环境信号,直接促进恶性肿瘤发生。糖蛋白也能相互组织,形成糖萼(glycocalyx)。近期在这一方面,来自康奈尔大学的研究人员发现了这种包被在细胞膜上的蛋白的物理特征是如何调控细

Nat Cell Biol:新型蛋白ASPP2可控制上皮细胞可塑性且抑制癌症转移

近日,来自牛津大学的科学家通过研究,揭示了控制机体上皮细胞形状和运动状态发生转变的关键机制,相关研究刊登于国际杂志Nature Cell Biology上;文章中研究者表示,名为ASPP2的肿瘤抑制蛋白的功能就好比是一种分子开关,其可以控制并且逆转机体上皮细胞的形状及运动状态的改变,这对于解释一系列生化现象,比如伤口愈合、胚胎发育及癌症转移都非常关键。 研究者Xin Lu表示,目前我们尽力去

抗疟疾药物氯奎宁或可有效抑制癌症的侵袭转移

近日,来自法兰德斯大学联办生物技术研究院的研究人员在对实验动物进行研究时发现,抗疟疾药物氯奎宁或具有明显的抗癌效应,截至目前,研究者们推测氯喹可以增加癌细胞对化疗的敏感性。研究者表示,氯奎宁同样可以使得肿瘤组织的异常血管正常化,结果从一方面来讲会增加癌细胞的屏障功能,进而阻断癌细胞的扩散和转移;从另一方面将则会增强肿瘤的灌注,使得其对化疗作用更为敏感。 氯奎宁是一种常见的用于治疗疟疾及

Scientific Reports:**软件可预测癌症转移

西部大学研究人员在实验室中开发出尖端的基因突变分析软件,来解释肿瘤基因组的突变,其可以帮助确定哪些乳腺癌更可能扩散到身体的其他部位,哪些肿瘤不会。 他们的结果发表在Scientific Reports杂志上。主要作者Stephanie Dorman表示:我们正在利用我们实验室的一个独特的软件方案,着眼于一种称为剪接突变类型的突变。 她说,以前遗传研究发现在445肿瘤中,这些剪接突变数目为4
