“一物降一物”,肿瘤细胞也不例外。中科院上海生化细胞所前天宣布:科研人员发展出一个针对原癌蛋白质YAP的抑制剂,为以胃癌为代表的肿瘤治疗提供了新策略和新途径。10日晚,国际肿瘤学顶尖学术期刊《癌细胞》在线发表了这项合作研究成果。

胃癌是世界范围内死亡率仅次于肺癌的恶性肿瘤,但目前国际上对胃癌的治疗手段非常有限。

近年来,人们找到一条重要的抑癌通路——Hippo信号通路。作为体内生化因子的传导路径,它在肿瘤发生发展及治疗方面的作用备受关注。原癌蛋白质YAP就是这条信号通路最下游的效应分子,大量临床分析发现,YAP在多种恶性肿瘤中的表达量上调明显,诱导癌细胞生长。因此,参与研究的沪上科学家认为,研发以YAP为靶点的抑制剂,可能更有效、更直接地纠正失调的Hippo信号通路,达到治疗肿瘤目的。

来自中科院生化细胞所及 “国家蛋白质科学中心·上海(筹)”的周兆才与张雷研、季红斌3个研究组合作,通过对胃癌病人样本的分析发现,YAP其实是有“克星”的。人体内存在一个天然拮抗剂蛋白——VGLL4,在胃癌组织中呈现明显下调趋势,且与肿瘤发展及恶化程度明显“负相关”。但由于这个天然“克星”VGLL4被打压,造成它与YAP之间的生理平衡被打破,因此癌细胞中的YAP处于过度激活状态,导致肿瘤生长失控。

可见,抗癌还需要一个“新克星”来“增援”。研究人员在蛋白质晶体三维结构解析的基础上,“瞄准”YAP设计并发展了一个多肽类抑制剂,可以模拟天然拮抗剂蛋白VGLL4的功能,进行治疗性干预。随后,他们采用多种技术手段,利用多个小鼠动物模型,确认这一多肽类抑制剂可有效抑制肿瘤生长。进一步的药理及毒理评估过程,也验证了带有失衡特征的癌细胞对这种抑制剂的特异敏感性。

周兆才研究员等认为,这项研究为胃癌治疗提供了一个新的选择方案,也可能为其它相似特征的恶性肿瘤提供个性化治疗策略。目前,相关研究成果已申请专利。

第八届中国老年肿瘤学大会会议通知

尊敬的肿瘤领域的同仁们:你们好!《中国老年学学会老年肿瘤专业委员会年会暨第八届中国老年肿瘤学大会》定于2014年4月11-13日在北京召开。“ 重视转化医学, 开展协作创新” 是第八届CGOS学术年会的年会主题,将在以下方面为重点:(1)老年肿瘤多学科、多领域的学术扩展;(2)以分子靶向为代表的老年肿瘤学深度研究;(3)老年肿瘤的临床多学科协作研究。会议将突出老年肿瘤学与分子肿瘤学的结合,针对

Cancer Res:驱动肿瘤转移的关键蛋白

在许多情况下,肿瘤细胞的扩散才是最致命的威胁。人们一直试图阻断肿瘤细胞的转移途径,但目前的治疗方式并没有取得理想的效果。 日前,Wistar研究所的科学家们发现,LIMD2是驱动肿瘤转移的关键蛋白,这项研究发表在三月份的Cancer Research杂志上。 研究人员指出,LIMD2蛋白与转移性的膀胱瘤、黑素瘤、乳腺瘤和甲状腺瘤有关。他们对这种蛋白进行了结构和功

Cancer cell:基底样乳腺癌新近进展

由美国肯塔基大学Markey癌症中心的研究员周斌华(Binhua P. Zhou)带领的一项最新研究表明,靶定人类细胞中EMT(上皮间质转化,epithelial-mesenchymal transition)的关键转录激活因子——Twist,可为治疗三阴性乳腺癌(triple-negative breast cancer)提供一种有效的方法。 三阴性乳腺癌(TNBC

Nature Methods:科学家发布肿瘤综合检测新技术

许多原因导致了研究人员在尖端医学时代却仍难以治愈癌症。 例如,肿瘤有可能是由不同的肿瘤细胞亚群所构成,每个细胞亚群具有自身的特性,对治疗产生差异性的反应。并且,体内的癌细胞和健康细胞彼此通讯及互作。而随后肿瘤如何形成以及是否形成转移灶则取决于肿瘤细胞从环境中接收到的信号。日前,来自苏黎世大学与苏黎世联邦理工学院的研究人员在《自然-方法》Nature Methods杂志上报告称,他们开发出了一
