Nat Commun:科学家解开恶性脑瘤难以治愈的难题

2014-07-11 佚名 生物谷

近日,刊登在国际杂志Nature Communications上的一篇研究论文中,来自蒙特利尔神经学研究所和麦基尔大学等处的研究人员通过研究揭示,一种名为SUMO(泛素样小蛋白)的蛋白质或许是肿瘤细胞无限增殖的关键,尤其是针对胶质母细胞瘤。SUMO家族蛋白可以修饰其它蛋白质,而且蛋白质经SUMO修饰后就会变得对许多细胞过程非常重要,鉴别出SUMO在癌细胞生长过程中的角色对于开发治疗胶质母细胞瘤

近日,刊登在国际杂志Nature Communications上的一篇研究论文中,来自蒙特利尔神经学研究所和麦基尔大学等处的研究人员通过研究揭示,一种名为SUMO(泛素样小蛋白)的蛋白质或许是肿瘤细胞无限增殖的关键,尤其是针对胶质母细胞瘤。SUMO家族蛋白可以修饰其它蛋白质,而且蛋白质经SUMO修饰后就会变得对许多细胞过程非常重要,鉴别出SUMO在癌细胞生长过程中的角色对于开发治疗胶质母细胞瘤的新型策略非常关键。

胶质母细胞瘤是一种常见的致死性脑癌,当前的标准化疗法包括外科手术、辅助化学疗法以及放疗方法,尽管如此患者往往生存期在一年半左右;癌症的持续增殖部分是因为癌症干细胞的存在,其对于理解癌症增殖的路径非常重要,因此以癌症干细胞为靶点的靶向疗法或许就可以帮助科学家们开发治疗胶质母细胞瘤的疗法。

通过细胞周期来控制癌症生长的分子机制,设计一系列的宿主蛋白以及许多复杂过程,这一机制尚不清楚,一组名为细胞周期素依赖的蛋白激酶(CDKs)可以驱动细胞周期,然而为何癌细胞中会维持高水平的CDK蛋白质也尚不清楚。

研究者Anita Bellail说道,在对人类胶质母细胞瘤细胞周期的调查研究过程中,我们发现CDK6可以被SUMO1修饰,CDK6被SUMO1修饰后可以抑制自身降解,从而可以稳定癌细胞中的CDK6蛋白质。CDK6的修饰需要胶质母细胞瘤癌症干细胞的自我更新及生长,而SUMO1的抑制则可消除癌症干细胞并且抑制癌症的恶化。

这项研究增加了SUMO修饰路径在人类癌症发生和发展过程中的证据,伴随着揭示SUMO影响癌症干细胞细胞周期的机制,科学家们就会寻找靶向作用SUMO1的药物,来开发治疗人类胶质母细胞瘤的新型疗法。

PNAS:质谱分析可能帮助指导脑瘤手术

使用一种基于质谱分析的技术探测肿瘤的代谢物,科研人员报告称,实时诊断可能有助于外科医生在手术室跟踪人类大脑肿瘤的范围。外科切除肿瘤常常需要诊断信息,目前是通过病理学家辛苦而耗费时间的活检显微检查获得的。 Nathalie Agar及其同事使用一种称为电喷雾解吸电离质谱(DESI-MS)的技术,用最少的样本处理在手术室迅速执行,从而检测2-HG,这是一种见于IDH-1 和IDH-2基因突变的人类

NAT GENET :揭示儿童脑癌根源

由德国癌症研究中心领导的一个科学家小组证实,一个过度活跃的信号通路是最常见的儿童脑癌——毛细胞型星形细胞瘤(pilocytic astrocytoma)的致病原因。通过研究96个病例,研究人员发现一些基因缺陷与一条特殊信号通路有关联。因此,可以利用药物来阻断这一信号级联反应的组成元件,帮助治疗疾病儿童。研究结果发布在最新一期的《自然遗传学》(Nature Genetic

Nature Genet:儿童侵袭性神经母细胞瘤致病基因被发现

  来自约翰霍普金斯大学Kimmel癌症中心和费城儿童医院(CHOP)的科学家们发表在12月2日的《自然·遗传学》(Nature Genetics)杂志上的一项研究结果表明:在对74个儿童神经母细胞瘤进行全基因组测序后,ARID1A和ARID1B两个基因发生改变的患儿相比无此基因改变的患儿生存期缩短了四分之三。这一发现有可能最终导致早期确认患有侵袭性神经母细胞瘤的儿童,他们或许需要接受其他的治疗。

MOL CANCER THER:CFAK-Y15可治疗神经胶质瘤

Vita M. Golubovskaya, PhD   美国罗斯维尔帕克癌症研究所(RPCI)近日发表报告称,他们在前临床研究中对一种被称为CFAK-Y15的小分子抑制剂治疗某些脑瘤的有效性进行了评估。这项被发表在《肿瘤分子治疗学》杂志上的研究首次证实,利用CFAK-Y15来抑制黏着斑激酶(FAK)的功能可有效控制胶质母细胞瘤的生长,尤其是当与标准化疗药物替莫唑胺(Temodar)联合使用

PLoS ONE:禁食让脑瘤对化疗更加敏感

在一项新研究中,来自美国南加州大学的研究人员首次证实控制性禁食(controlled fasting)改善在癌症治疗中的化疗疗效,延长患有侵袭性脑瘤的小鼠的预期寿命。 在这项刊登在PLoS ONE期刊上的最新研究中,研究人员首次证实禁食时间似乎提高化疗在治疗神经胶质瘤上的疗效。神经胶质瘤是一种最为常见被诊断出来的脑瘤。患有神经胶质瘤的病人平均存活期限小于两年。 论文通信作者Valter Lon

手机或增脑癌风险

    频繁长时间使用手机、喜欢把手机放在枕头边上等可能增加患脑肿瘤风险。在举行的第六届上海国际神经外科大会上,中国工程院院士、复旦大学附属华山医院神经外科主任周良辅教授披露,我国每年因为脑胶质瘤死亡人数达到十万人。   第六届上海国际神经外科大会上,来自国内外200多名脑神经外科专家汇聚一堂,就中国首部《中国中枢神经系统胶质瘤诊断和治疗指南》进行了深入探讨。
