Nature Genetics:多国科学家共同发现卵巢癌新易感位点

2015-02-02 佚名 生物谷

近日,来自英美法德等多个国家的研究人员共同在国际著名期刊Nature Genetics刊登了他们的最新发现,他们利用GWAS方法以及对大量临床病例和BRCA1/2突变基因携带者进行相关性分析,发现了6个新的侵袭性上皮卵巢癌(EOC)易感位点。这项研究对提高针对BRCA1/2突变基因携带者进行的临床风险预测准确率具有非常重要的意义。   研究人员指出,之前的研究发现携带BRCA1/2突

近日,来自英美法德等多个国家的研究人员共同在国际著名期刊Nature Genetics刊登了他们的最新发现,他们利用GWAS方法以及对大量临床病例和BRCA1/2突变基因携带者进行相关性分析,发现了6个新的侵袭性上皮卵巢癌(EOC)易感位点。这项研究对提高针对BRCA1/2突变基因携带者进行的临床风险预测准确率具有非常重要的意义。
 
研究人员指出,之前的研究发现携带BRCA1/2突变基因的人群具有发生上皮卵巢癌的高风险性,在基于人群的全基因组关联性分析(GWAS)中已经发现12个上皮卵巢癌易感等位基因,这些位点的关联模式与BRCA1/2突变基因携带者的关联模式呈现一致性。在对1000项基因组计划数据进行归责后,研究人员对大量临床样本和BRCA1/2突变基因携带者的基因进行了遗传变异与发生EOC风险的相关性分析,发现了6个新的EOC易感位点,都与EOC风险具有明显相关性。
 
综上所述,该文章通过对大量临床病例和BRCA1/2突变携带者进行相关性分析,发现了6个新的可能增加上皮卵巢癌发病风险的易感基因。这项研究对临床预测EOC风险,预防和治疗EOC都具有非常重大的意义。

Nat Commun:科学家确认卵巢癌一对重要致癌基因和抑癌基因

卵巢透明细胞癌(OCCC)是卵巢癌种类中恶性程度高的一种,对化疗不敏感,预后不良。近日,美国University of North Carolina医学院的一群研究人员找到了OCCC发生的两个重要基因ARID1A和PIK3CA,当这两种基因同时发生突变,OCCC的发生率是100%。这篇研究发表在最近一期的 根据以前的癌症基因组测序的结果,研究人员已经知道ARID1A是很多肿瘤,包括OCCC的

近日,维也纳医科大学综合癌症中心的Stefanie Aust等对上皮性卵巢癌(eoc)生物学研究的最新概况进行总结,并将其发表在Wien Med Wochenschr杂志上。研究人员重点关注了EOC的起源、复杂的异质性和最新治疗方法。另外,肿瘤微环境的作用、腹膜腔传播的高度可能性和新的分子生物学研究结果也在本文中进行了总结。 最新的分子生物学特性将上皮性卵巢癌(EOC)作为一种高度异

AJOG:卵巢癌终身风险能否降低?

卵巢癌位列妇女常患癌症的第八位,在2014年大约有二万二千名新病例被发现,同时有超过一万四千妇女的死亡估计与此相关。一名女性在一生中有1/70的机率会罹患卵巢癌。癌症早期通常不具有典型性症状,这也意味着卵巢癌通常发展到后期才会被诊断出。而在此期间,治疗效果会事倍功半,但预后较差。 关于卵巢癌的发病原因,很多理论被提出来。浆液型输卵管癌常伴发浆液性卵巢癌或原发性腹膜肿瘤。而很多人认为上述这些癌症中
