我国科学家运用全基因组关联分析方法,首次在汉族人群中发现两个宫颈癌遗传易感变异位点,这一成果发表在国际顶级专业期刊《自然-遗传学》(Nature Genetics)杂志上。

华中科技大学同济医院 16 日举行新闻发布会,介绍了马丁教授带领的科研团队在宫颈疾病研究领域这一阶段性成果。宫颈癌是威胁妇女生命健康最严重的疾病之一,近年来呈现明显年轻化趋势,我国宫颈癌患者平均发病年龄比 10 年前年轻了 5 岁以上。高危型 HPV 病毒的持续感染是宫颈癌发病的主要风险因素,超过99%的病例均检测到HPV病毒感染。然而,临床研究发现,超过 70% 的女性一生中有过一次以上的一过性HPV感染,但只有极少数导致宫颈癌。

马丁说,这一现象表明,人作为宿主的遗传特征是导致宫颈癌发生的内在原因。但长期以来,人们对HPV感染导致宫颈癌的机制不明确,对导致宫颈癌发病的遗传易感基因知之甚少。过去3年多时间里,马丁带领的研究团队,检测了浙江、上海、江苏、广东、北京、湖南等地数十家医疗机构收集的 16484 个样本,开展了大规模研究论证,首次发现我国宫颈癌遗传易感变异位点 4q12 和 17q12,分别位于 4 号染色体和 17 号染色体上。

马丁说,遗传易感变异位点的发现,可用于宫颈癌风险预测,圈定高危人群后,将来的疫苗注射策略可从“全体适龄人群”缩小为“高危易感人群”,有利于探索符合我国国情的疫苗防治方案。成果还对早期临床诊断、个体化治疗、新药研发等具有重要意义。

宫颈癌筛查新改革

  没有什么能比一个名人的名字更能引起全球对一大健康问题的关注。因此,我们现在用“朱莉效应”来形容女星安吉丽娜·朱莉对人们乳腺癌检查的影响力,据报道该检查翻了一倍。这对全球女性最常见的癌症而言是一个好消息。   事实上,在发达国家本病占死亡人数的近四分之一。其实早期诊断也是可以预防的,但癌症的筛选技术仍然需要进一步改善。   AUTOCAST(基于实时PCR的自动癌筛查)已经能够解决得

CDC:接种疫苗后HPV感染减少56%

  美国疾病预防控制中心(CDC)的一项研究显示,在年龄14~19岁的女性中,由四价人乳头瘤病毒(HPV)疫苗中所含的HPV亚型引起的感染,在这种疫苗上市并被推荐为女性常规接种项目之后4年内减少了近60%。   CDC的医学流行病学家Lauri Markowitz博士指出,鉴于仅有大约1/3的年轻女性已接种了推荐的全部3剂HPV疫苗,上述结果好于预期。这篇报告发表在6月19日《感染病学杂志》在线

中国科学报:印度议会痛批美宫颈癌疫苗项目存缺陷

   印度两万多名少女参与了宫颈癌疫苗试验。   那些希望在印度进行临床试验的研究人员,又将面临一场风暴。 近日,印度议会的一个小组严厉批评了美国一家非营利机构及其印度合作伙伴。该小组声称它们在一种预防由人乳头状瘤病毒(HPV)引起的宫颈癌的疫苗试验中,违反了伦理要求。 新德里公共卫生基金会负责科研的副主席、流行病学家Ramanan Laxminarayan预测称,该

BJC:miR-375或为紫杉醇抗性宫颈癌的靶点

化疗耐药性是引起癌症患者死亡的关键因素,肿瘤化疗敏感性越低,癌细胞越难杀死。宫颈癌是妇女中最常见的恶性肿瘤,并且在临床上对化疗不敏感。越来越多的证据表明,microRNAs(miRNAs)在癌症化疗敏感性的调控中扮演着重要的角色。近日,浙江大学医学院谢幸教授,领衔其团队,对miRNA在宫颈癌的紫杉醇敏感性中的作用进行了系统研究*,研究结果发表在6月刊的British Journa

Lancet:人乳头瘤病毒早期筛查可有效筛查宫颈癌

宫颈癌是最常见的女性恶性肿瘤之一,宫颈涂片筛查是目前最常用的宫颈癌筛查方法。而欧洲一项最新研究发现,进行针对人乳头瘤病毒( HPV )的早期筛查可以更加高效地帮助筛查宫颈癌。 据英国国家医疗服务系统癌症筛查项目主管朱丽叶塔·帕特尼克介绍,英国已经有部分地区开始推行针对 HPV 的宫颈癌早期筛查,检测出 HPV 的女性再接受阴道镜等进一步检查,这一手段取得了良好效果。

JBC:宫颈癌细胞增殖机制获进展

近日在中科院广州生物医药与健康研究院获悉,该院科学家在抑制宫颈癌细胞增殖机理方面取得新进展。研究成果已在线发表于美国《生物化学杂志》(JBC)上。 据介绍,CCCTC结合因子(以下简称CTCF)是含有11个高度保守的锌指结构蛋白,具有多种生物学功能。已有研究发现CTCF可以抑制原癌基因c-Myc的表达,在细胞生长与增殖以及肿瘤发生等方面都起着非常重要的作用。 最近,广州生物院姚红杰博士和潘光锦
