Nat Genet:与东亚女性乳腺癌有关的3种基因

2014-09-10 张笑 中国科学报

在线发表于《自然—遗传学》上的一项研究报告了影响东亚女性乳腺癌的3种遗传变化。这项研究结果为这类人群的乳腺癌遗传学研究提供了新见解。 大多数乳腺癌研究聚焦的研究对象是具有欧洲血统的女性。Qiuyin Cai等人研究了超过22000位患有乳腺癌的东亚女性,确定了数个可导致乳腺癌发生的针对亚洲的特定遗传变化。 他们找到靠近3种基因——ARRDC3、 PRC1和ZC3H11A的D

在线发表于《自然—遗传学》上的一项研究报告了影响东亚女性乳腺癌的3种遗传变化。这项研究结果为这类人群的乳腺癌遗传学研究提供了新见解。

大多数乳腺癌研究聚焦的研究对象是具有欧洲血统的女性。Qiuyin Cai等人研究了超过22000位患有乳腺癌的东亚女性,确定了数个可导致乳腺癌发生的针对亚洲的特定遗传变化。

他们找到靠近3种基因——ARRDC3、 PRC1和ZC3H11A的DNA序列变化。其中两种序列变化的确认位置在负责调控其他周围基因表达的部分基因组中。

ARRDC3和PRC1突变分别与乳腺癌生长和乳腺癌患者存活率有关联。而ZC3H11A在乳腺癌中的作用仍未知。

CANCER EPIDEM BIOMAR:佩戴胸罩并非导致乳癌发病率增加的原因

据发表在Cancer Epidemiology, Biomarkers & Prevention杂志的一项研究证实,女性佩戴胸罩并不增加乳腺癌的患病风险。为明确胸罩与乳腺癌之间的联系,研究人员对不同款式的胸罩、首次佩戴胸罩的时间,以及每日佩戴时间进行了数据采集。结果显示,二者并无显著的联系。本研究的作者,来自华盛顿大学公共卫生学院的博士研究生Lu Chen说:“williamhill asia 并未发现胸罩与乳腺癌有关

PNAS:美发现一种可控制乳腺癌转移的酶

近日,美国加州大学圣地亚哥医学院的研究人员发现并确定了一种酶,这种酶能控制乳腺癌的转移。研究结果发表在最新一期的《美国国家科学院院刊》上,这为全球乳腺癌死亡的主要原因提供新依据。据美国癌症协会估计2014年在美国估计约有40000名妇女将死于乳腺癌。 “这项研究的关键信息是williamhill asia 发现了一种通过酶调整途径来靶向治疗乳腺癌的方法。”第一作者吴雪峰说,他是加州大学圣地亚哥分校的博士后研究员。这种

JAMA:双侧乳腺切除术可能没有必要

双侧乳腺切除术是否有利于乳腺癌患者的长期生存?存在巨大争议。以往随机对照研究显示,早期乳腺癌采用保乳术加放疗或乳腺切除术,长期生存是相似的。但是,大量资料显示,乳腺切除术,尤其是双侧乳腺切除术逐年增加。双侧乳腺切除术有两个目的,一是为了治疗乳腺癌,二是为了预防对侧乳腺癌。为什么双侧乳腺切除术如此风迷,尚没有合理的解释,有一个重要理由是基因层面的因素。因为BRCA1和BRCA2基因可能与乳腺癌高发有

镜头下的乳腺癌患者

近日,纽约摄影师大卫?杰伊(David Jay)发布了一组震撼人心的图片,图片记录了乳腺癌患者术后重生的影像,同时向人们展示了她们与疾病抗争的勇敢与自信。全球乳腺癌发病率自上世纪70年代末一直呈上升趋势,中国虽不是乳癌高发国,但近年发病率增长速度高过高发国。 乳腺癌的发病原因尚未完全清楚,但研究发现乳腺癌发病有一定规律。 1、中国肿瘤登记年报显示:女性乳腺癌年龄别发病率0~24岁年龄段

Genome Biology:英开发IntClust系统改善乳腺癌治疗

最近,英国科学家们开发出一种新的工具,可以将乳腺癌分为十种不同的亚型,有望改善这种疾病的治疗效果。相关研究结果发表在2014年8月28日的Genome Biology杂志。 癌症的发生,是因为遗传变化使正常细胞发展为肿瘤。随着对乳腺癌了解的增多,williamhill asia 知道,这不是一种单一的疾病——引起不同类型癌症的基因突变是不一样的,这就是为什么肿瘤对治疗的反应有差异,为什么它们会以不同的速度生

谭先杰:遗传性乳腺癌和卵巢癌是否要预防性切除

1990年,研究者发现了一种直接与遗传性乳腺癌有关的基因,命名为乳腺癌1号基因,由于说的是乳腺癌(Breast Cancer),于是英文简称BRCA1,它位于人体细胞核的第17号染色体上。1994年,研究者们在第13号染色体上又发现另外一种与乳腺癌有关的基因,称为BRCA2。在此之后,很多情况下都会把两种基因统称BRCA1/2一起讨论。 实际上,BRCA 1/2是两种具有抑制
