美国德州大学MD安德森癌症中心的研究人员发现ZEB1蛋白质可帮助乳腺肿瘤细胞修复因辐射疗法带来的DNA损伤,进而可促使乳腺癌对放射疗法产生耐受性。该研究成果于2014年8月3日在线发表在《自然·细胞生物学》(Nature Cell Biology)杂志上。

放射疗法可导致癌细胞DNA断裂死亡,且癌细胞DNA不能修复自身损伤,癌干细胞可通过激活细胞自身的DNA损伤反应系统来促进癌细胞对放疗的耐受性,但机制不明。而在治疗乳腺癌的过程中,克服肿瘤细胞对放疗产生耐受性,揭示耐受的机制十分重要。

该研究发现ZEB1蛋白可诱发癌细胞上皮细胞间质转化(epithelial-mesenchymaltransition,EMT)过程,使其具有包括对放疗的耐受性在内的癌症干细胞的特性。EMT过程是机体对伤口愈合的一种反应,也是癌症细胞进行恶化扩散的一种方法。ZEB1蛋白可通过一系列复杂的反应使ATM基因促进蛋白质Chk1稳定表达,Chk1在DNA的损伤反应过程中扮演着重要角色,进而通过促进USP7酶的表达来提高肿瘤对放疗产生耐受性。

Cancer Res:近期使用口服避孕药或增乳腺癌发病风险

《癌症研究》杂志8月1日发表的一项巢式病例对照研究显示,近期使用口服避孕药的女性发生乳腺癌的风险,比以前曾使用或从不使用口服避孕药的女性增加50%(Cancer Res. 2014;74:4078-89)。 研究者比较了1990~2009年期间1102例年龄20~49岁、曾被诊断为浸润性乳腺癌的女性患者和21755名来自相同医疗系统且年龄、年份、入组时间长度和医疗情况匹配的对照者。

Cancer Res:NSAIDs降低乳腺癌肥胖患者癌症复发风险

近日,一项新研究确定,接受激素治疗作为治疗方案一部分的绝经后体重超重或肥胖的乳腺癌患者,使用非甾体抗炎药(NSAIDs)如阿司匹林或布洛芬,乳腺癌复发率显著降低和癌复发时间大大延迟。这项研究结果发表在8月14日的Cancer Research杂志上,新研究提示了一种减少超重和肥胖绝经后妇女(这些女性复发的相对风险较高)乳腺癌复发率的新可能性。对人体临床研究和细胞培养实验研究进行回顾性分析,研究人员

CEBP:体能锻炼或可降低非裔美国女性罹患乳腺癌的风险

对于非洲裔美国女性来讲,正常的锻炼,包括健步走,和乳腺癌发生率下降直接相关;近日,刊登在国际杂志Cancer Epidemiology,Biomarkers & Prevention上的一篇研究论文中,来自波士顿大学医学中心的研究者通过研究表明,在非洲裔美国女性群体中体能锻炼或会降低乳腺癌的发病风险。这项研究中,研究人员对4.4万名非洲裔美国女性进行了长达16年的跟踪调查研究,收集了其锻炼

Cancer Res:昼夜节律紊乱可致乳腺癌他莫昔芬耐药

美国一项研究显示,夜间微弱光照(dLEN)引起的褪黑激素产生失调可导致乳腺癌对他莫昔芬治疗不敏感。论文7月25日在线发表于《癌症研究》(Cancer Res)。 研究人员使用人乳腺癌细胞系MCF-7[雌激素受体(ER)阳性]建立大鼠异种移植肿瘤模型,在正常昼夜光照节律或dLEN以及dLEN条件下补充或未补充褪黑激素条件下,观察肿瘤的生长转移情况和对他莫昔芬的敏感性。结果发现,dLEN条件

NEJM:乳腺癌3号致癌基因

很多人都知道女性的BRCA1和BRCA2基因发生突变,可增加女性患乳腺癌的风险。这两种基因分别于1991和1993年被发现,最近来自英国剑桥大学的研究者发现可致乳腺癌的第三种基因,该基因为PALB2,位于人体第16号常染色体上。携带PALB2基因突变,通常会在年龄较大时会出现乳腺癌(70岁),而携带BRCA1/2突变基因的患者, 通常发生在年轻女性身上。PALB2基因也是目前被确认与乳腺癌有关的第

Mol Endocri:科学家发现治疗乳腺癌新型疗法的靶点

近日,来自昆士兰大学的研究人员通过研究发现了一种新型的乳腺癌靶向疗法,研究者George Muscat表示,携带特殊遗传标签的的乳腺癌患者在癌症不扩散的前提下或许更易于存活,相关研究成果刊登于国际杂志Molecular Endocrinology上。文章中,研究者发现了一种可以被癌症药物靶向作用的蛋白质,Muscat教授表示,我们对来自100位乳腺癌患者的组织样本进行了检测,发现机体酶类PRMT2
