日前,一项发表在国际杂志Genome Research上的研究报告中,来自韦恩州立大学医学中心的研究人员通过研究首次揭示了环境暴露和遗传突变之间的相互作用如何对机体健康和诸如糖尿病等多种疾病产生明显的影响,该研究或将加速未来精准医学的研究步伐。

这项研究非常重要,因为具有不同血统的群体都共享着相同的环境风险因子,一般来讲,人们往往会共享相同的遗传风险因子,但人们患上疾病的风险和机会往往会因特殊的环境暴露而增加,科学家们往往很难对环境进行测定,尤其是当我们尽力想去研究这些复杂的相互作用时,举个例子,研究者们往往很难对个体一生中所经历的压力水平来定量测定,或者很难测定个体饮食中的咖啡因或维生素的含量。

研究者Francesca Luca博士指出,基因和环境条件都会对机体健康带来重大影响,比如,压力是诱发心血管疾病的风险因子,然而实际上个体心脏病发作的风险不仅依赖于其一生中所经历的压力水平,还依赖于其从父母辈遗传的特殊DNA序列—遗传突变。在人类进化历史过程中遗传突变和环境因子之间的相互作用能够为我们提供驱动力来塑造基因组,过去能够帮助我们储存脂肪能量的遗传适应性如今或许会让我们更容易患上某些疾病,比如糖尿病或肥胖等。

从有机体的水平上来讲,研究遗传突变和环境之间的相互作用或许还是一项需要解决的复杂问题,研究者在分子水平上揭示了250种不同的细胞环境中基因表达所发生的改变情况,其中包括咖啡、维生素、金属离子、激素、污染物和常见的药物等。Luca说道,我们的细胞系统能够简化环境的复杂性,并且能够让我们开发出强大的统计学检测技术检测出215个活性能够被调节的基因,而这些基因的活性能够被同我们所控制的环境发生相互作用的遗传突变所调节。更让研究者惊讶的是,50%的在基因中发生的相互作用对于人类疾病的发生都非常重要,比如在GIPR基因中发生的一种相互作用就表明,在遗传性保护因子存在的情况下咖啡因的摄入就能够降低个体患肥胖的风险,类似地,当LAMP3基因中遗传风险因子存在的情况下,较低水平的硒摄入或许就会增加个体后期患帕金森疾病的风险。

本文研究是研究者首次进行的一项大规模的基因组研究,他们通过研究发现,个体所处的环境和机体遗传组成或许会直接影响机体的健康;目前研究小组正在调查环境暴露和遗传突变之间发生相互作用的精确分子机制,从而为深入探索额外的环境暴露(比如人类微生物组),并且在更多非洲裔美国人群体中进行类似地研究来寻找更多新型的遗传突变提供新的线索和希望。

Nat Genet:关键遗传突变或可帮助预测癌症患者进行放疗引发的副作用风险

2014年7月10日 讯 /生物谷BIOON/ --近日,刊登在国际杂志Nature Genetics上的一篇研究论文中,来自西奈山医学院的研究人员通过研究揭示,关键的遗传突变或许会影响癌症病人对放射疗法的反应,研究者表示,在前列腺癌患者中,基因TANC1的突变和放疗诱发的副作用风险增加直接相关,这些副作用包括机体失禁、性无能及腹泻等。 基于全基因组关联性研究,研究人员检测了大量的遗传突变来

科学家在中国人群中发现新型的乳腺癌遗传突变

近日,来自香港大学的研究人员通过研究鉴别出了一种新型的遗传突变和高风险的乳腺癌直接相关,该研究或可帮助进行个体的遗传筛查来寻找中国乳腺癌家族史的发病起源。携带BRCA1和BRCA2遗传突变的个体往往是高风险的乳腺癌发病个体,但这些突变通常仅出现在10%至15%的遗传性乳腺癌中,目前还有许多其它许多突变需要被研究阐明。 在3月10日举办的欧洲乳腺癌会议上,研究者Ava Kwong就描述了和中国少数

PLoS ONE:遗传突变PlA1/A2或可增加个体卒中及心脏病的发病风险

近日,来自伦敦国王大学的研究人员通过研究鉴别出了和中风及心脏病发病风险增加相关的遗传突变,相关研究成果刊登于国际杂志PLoS ONE上。 当动脉被形成的脂质产生的血块完全堵住后就会引发中风或者心脏病发作,引发中风、心脏病发作的风险因素包括吸烟、高血压以及高胆固醇症;研究者St Thomas' Charity说道,这项研究中我们发现了一种名为糖蛋白llla的突变,这种遗传突变往往发生于血小板中

HMG:罕见的遗传突变或可引发个体患严重的脊柱侧凸

科学家们研究发现机体两个基因发生罕见突变的儿童发生严重脊柱侧凸的风险是正常个体的四倍,近日,刊登在国际杂志Human Molecular Genetics上的一篇研究报道中,来自华盛顿大学医学院的研究人员通过研究鉴别出了引发儿童患脊椎S形曲折的遗传风险因子,这种疾病往往需要通过手术来进行治疗。 文章中,研究者Christina A. Gurnett博士表示,长期以来我们一直在寻找

Nat Commun:遗传突变会影响他汀类药物效应

近日,刊登在国际杂志Nature Communications上的一篇研究报告中,来自伦敦女王大学的科学家们通过对4万名进行他汀类药物治疗的患者的大型分析研究后鉴别出了两种新型的遗传突变,这两种遗传突变可以影响机体坏胆固醇对他汀类疗法的反应。 他汀类药物是临床中广泛使用的用于降低坏胆固醇的药物,其可将坏胆固醇水平降低至55%,从而可以有效减少心脏病的风险,尽管如此,不同病人对他汀类药物的

Mol Autism:常见遗传突变或增加自闭症风险

诱发自闭症及自闭症谱系障碍(ASD)的原因非常复杂,这些原因中包含有基因诱发的或者环境所导致的自闭症。一项刊登在国际杂志Molecular Autism上的研究报道揭示了常见的遗传多态性即遗传突变,可以增加自闭症谱系障碍的风险。 曾有研究报道,影响自闭症谱系障碍的遗传因素并不清楚,因为当罕见的遗传突变影响ASD风险表现出较为明显症状的时候,常见的突变,比如单核苷酸多态性对其影响就会变得不能容易分
