Nature提出细胞自毁新学说

我们染色体末端的特殊结构——端粒决定了细胞可以在多长的时间里继续复制自身。长期以来人们一直在研究它与衰老过程和癌症的关联。现在来自Salk研究所的一个研究发现表明,在细胞阻止肿瘤的自毁程序中端粒有可能比以往认为的要更加重要,有可能可以利用这一功能来改善癌症治疗。这项研究发布在《自然》(Nature)杂志上。

当细胞在有丝分裂过程中进行复制时,它们的端粒每次都会缩短一点点。最终,在多次的细胞分裂后,端粒会变为极短,由此向细胞发出停止分裂的信号。这一正常的过程充当了抵御癌症的屏障。这一信号通路存在缺陷的细胞,会继续越过这一阶段进行自毁。

这一细胞毁灭过程通常可以阻止遗传不稳定或受损的细胞进行复制。但许多的癌细胞可通过保护端粒来阻止这一自毁信号绕过这一危机,使得细胞可以继续增殖。

论文的资深作者、Salk分子和细胞生物学实验室教授Jan Karlseder说:“我们着手去了解危机中的细胞死亡机制,发现端粒作为肿瘤形成的障碍,发挥了比以往认为的更加主动的一种作用。一切是这样开始的,我们看到了一些逼近危机的细胞有丝分裂时间更长。”

通常有丝分裂大约需要30-45分钟,而即将陷入危机的细胞有丝分裂时间则要持续2-20个小时以上的时间。观察到这一现象让研究人员想起了2012年的一个研究发现,当时他们认为地延长了有丝分裂过程。通常,端粒有一个蛋白保护它们避免被细胞识别为受损DNA,由此可以阻止它们执行细胞死亡。然而在人为延长有丝分裂的过程中,端粒丢失了这一蛋白,激发了一种DNA损失信号,推动细胞进行自毁。

让科学家们惊讶地是,他们发现在自然危机状态下发生了几乎完全一样的事情。在新研究工作中,研究人员对细胞皿中的细胞进行了实时成像,追踪了通过一个或多个有丝分裂周期的细胞的命运。他们发现一种叫做端粒融合的细胞压力可引起有丝分裂时间延长,并最终导致危机。这种状态下的细胞会丧失它们的端粒保护蛋白,激活自毁程序。

Karlseder说:“一个长期存在的假说被证实是错误的:细胞只是一开始融合和断裂染色体,就造成了不稳定和细胞死亡。我们证实,它是一个更有针对性的通路,只需一个细胞周期就可以引起危机——它与缓慢和稳定地累积基因组不稳定性无关。”

澳大利亚儿童医学研究所基因组完整性研究小组Anthony Cesare说,这一研究发现令人感到非常兴奋,并意外地看到了细胞周期早期的事件:端粒融合是如何传递至细胞周期的后期有丝分裂阶段的。“这为了解端粒控制细胞生长的机制以及端粒生物学对化疗的意义打开了新的途经。”

几种化疗药物,例如治疗乳腺癌的紫杉醇都是通过破坏有丝分裂,使得癌细胞无法继续分裂来阻止癌症。研究人员猜测它们可以通过首先去掉端粒的保护来使得细胞对药物更加敏感从而增强这些有丝分裂抑制剂的疗效。也有可能可以看到,如果来自一种特定肿瘤的细胞具有更短或去保护的端粒,可以预计这种肿瘤对有丝分裂抑制剂更加的敏感。

论文的第一作者、京都大学研究人员Makoto Hayashi说:“我们发现的这一信号通路挑战了长期以来有关肿瘤形成早期过程中细胞行为的假说。全面了解这一信号通路将有望为我们提供一种新方法来进行早期肿瘤诊断,并为极早期的癌症提供治疗机会。”

这一实验室目前正与加州大学圣地亚哥分校的Deborah Kado博士合作,在新确诊乳腺癌的患者中测试这些理论。

Lancet oncol:良好生活方式确能延缓衰老

人们都知道健康饮食、适量运动对身体有好处。一项最新研究从细胞老化角度进一步证实,保持良好的生活方式,的确能延缓衰老。 据介绍,人体细胞内的染色体上有称作端粒的结构,它好比鞋带两头防止磨损的“保护帽”。人出生时,染色体端粒都有一定长度。随着细胞不断分裂和老化,端粒会慢慢变短。因此,端粒长度被用作判断衰老程度的重要标志。 英国新一期《柳叶刀—肿瘤》杂志刊登美国研究人员的论文说,一项有35名前列腺癌

诺贝尔医学奖专家揭开人类长寿“开关”

保护端粒,人类长寿的“开关”———访诺贝尔生理学或医学奖获得者伊丽莎白·H·布莱克本博士长寿是从古到今无数人追求的目标。其实,前沿科学早已揭开了人类衰老的密码,这个密码就是存在于染色体上的“端粒”。近日,《生命时报》记者专访了端粒和端粒酶研究领域的先驱、2009年诺贝尔生理学或医学奖获得者伊丽莎白·H·布莱克本博士,请她揭开端粒———这个关系人类健康与寿命的神秘物质的面纱。生命时报:尊敬的伊丽莎白

JNCI:预测寿命?要看端粒长度!

端粒(Telomeres)是存在于真核细胞线状染色体末端的一小段DNA-蛋白质复合体,它与端粒结合蛋白一起构成了特殊的“帽子”结构,作用是保持染色体的完整性和控制细胞分裂周期。端粒、着丝粒和复制原点是染色体保持完整和稳定的三大要素。端粒DNA是由简单的DNA高度重复序列组成,端粒酶可用于给端粒DNA加尾,DNA分子每次分裂复制,端粒就缩短一点,一旦端粒消耗殆尽,细胞将会立即激活凋亡机制,即细胞走向

Nat Genet:研究发现端粒更长增患脑癌风险

据美国加州大学旧金山分校(UCSF)科学家领导的最新基因组研究揭示,两个普通的基因变异会使染色体端粒变得更长,但也会大大增加患神经胶质瘤脑癌的风险。此前许多科学家认为,端粒的功能只是防止细胞老化,保持细胞健康。相关论文在线发表于最近的《自然—遗传学》网站上。据物理学家组织网6月8日报道,这两个基因变异是TERT(端粒逆转录酶)和TERC(端粒酶),51%的人携带TERT变异,72%的人携带TERC

Cell Stem Cell:为何从古至今女人都长寿?

人类中的超级百岁老人(即年龄超过110岁的人)至少都会有一个共同点,即超过95%的百岁老人都是女性,科学家们通过长期研究观察当人们衰老时不同性别之间个体的差异,但研究者目前并不清楚为何女性会活的更久一些。近日,刊登在国际杂志Cell Stem Cell上的一篇研究报道中,来自斯坦福大学的研究人员通过对干细胞的行为和性别差异进行研究,揭示了男性和女性随着机体老化而表现出的再生能力下降的差异,相关研究

英媒:新检测法可早十年准确“预报”癌症

英媒称,科学家发明了一种新检测方法,能够100%准确地预测一个人在今后13年内是否会患癌症。据英国《每日邮报》网站5月1日报道,哈佛大学和西北大学发现,在癌症被诊断出的10多年前,人体已经在发生细微但重要的变化。他们发现,在后来患癌症的人体内,染色体末端防止DNA受损的保护帽明显磨损更严重。事实上,它们看起来像是属于年长15岁的人。保护帽称为“端粒”。这些人体内的端粒比应有长度更短,而且持续变短,
