Nature Genetics:全球研究揭示基因作为炎性疾病的主要原因

2016-03-21 佚名 生物谷

一项50家不同研究中心参与的全球研究发现了数百个导致5种常见、难治炎性疾病的基因,为开发这些疾病的新疗法铺平了道路。 这项研究由澳大利亚昆士兰科技大学(QUT)和德国基尔大学(Christian-Albrechts-University)领导,最新发表于国际期刊《Nature Genetics》。 该研究共同资深作者、QUT健康和生物医学创新研究所教授Matthew Brown说,他们研究了强

一项50家不同研究中心参与的全球研究发现了数百个导致5种常见、难治炎性疾病的基因,为开发这些疾病的新疗法铺平了道路。

这项研究由澳大利亚昆士兰科技大学(QUT)和德国基尔大学(Christian-Albrechts-University)领导,最新发表于国际期刊《Nature Genetics》。

该研究共同资深作者、QUT健康和生物医学创新研究所教授Matthew Brown说,他们研究了强直性脊柱炎、克罗恩病和溃疡性结肠炎(统称为炎性肠病)、牛皮癣和原发性硬化性胆管炎。

"这些疾病影响大约3%的世界人口,通常一同发生于家族和个人中。最大的问题是,这是否是由共同的环境风险因素或共同的基因导致,现在我们相信我们有了答案"Brown教授说道。

"新的研究最终证明,这些疾病伴发的原因主要是因为它们共享相似的遗传背景。"

"在对来自26个国家近86000名对象的研究中,我们的研究人员识别出244个控制人们是否罹患这些疾病的遗传变异体,其中大部分是全新的发现。

"他们发现,这些疾病经常伴发于个人的原因是因为这些不同的疾病共享遗传危险因素,而不是一种疾病引起其他的疾病。"

"对某些疾病,比如常见形式的脊柱关节炎,强直性脊柱炎,研究将所涉及基因的数量增加了大约两倍。"

Brown教授说,新基因的发现指向一些潜在的新疗法,包括已经用于其他疾病的疗法,现在这些疗法可以非常迅速地试用于这些疾病。

"新发现揭示了这些疾病的原因,比如识别最有可能被肠道细菌影响的遗传风险变异体,导致关节、肝脏或肠道本身的炎症"Brown教授说道。

"在我们理解这些常见但难治性疾病的过程中,这些研究结果是一个重大飞跃。"

"我们知道这些疾病频繁伴发于个人和家族中已经有50多年了。我们现在知道这主要是因为所涉及的基因影响了许多疾病的风险,因此,尽管这些疾病以如此不同的方式出现,但却拥有非常相似的根本原因。"

"这项研究为我们指出这些疾病的数个不同的潜在疗法靶点,全球范围内,对这些疾病更好的疗法的需要是巨大的。"

清华施一公院士PNAS发表乙肝新成果

来自清华大学的研究人员对抗凋亡蛋白Bcl-2与乙肝病毒蛋白HBx之间的互作进行了结构与生物化学分析,研究结果发布在2月8日的《美国国家科学院院刊》(PNAS)上。

“好”胆固醇未必有益健康

“好”胆固醇有益健康?这个说法已有几十年,但一项最新研究显示并不一定是这样。 高密度脂蛋白胆固醇被认为可降低心脏病风险,因而被称为“好”胆固醇。但美国宾夕法尼亚大学等机构研究人员在新一期美国《科学》杂志上发表论文说,“好”胆固醇增多也可能由某种罕见的基因突变引起,在这种情况下心脏病风险反而升高。 胆固醇不能溶解于血液中。通常认为,它须依附在脂蛋白上才能从周边组织进入肝脏,在这里被分解代谢、

Ther Clin Risk Manag:根面平整联合米诺环素局部应用可降低主要牙周致病菌的水平改善患者的症状本研究旨在通过评估慢性牙周炎患者治疗后的各临床参数和四种主要的牙周致病菌的荷载量来评估分别单独应用或局部应用2%的米诺环素(MO)联合根面平整(SRP)的治疗效果。研究共纳入70名慢性牙周炎患者,随机分为三组:1)单独使用SRP;2)单独使用MO;3)SRP联合MO使用(SRP + MO)

Neuron:睡不着?说明你缺钙

最近一项研究指出,多食富含钙的食品有助于睡眠。 日本东京大学的研究人员指出,钙对保持机体的骨骼和牙齿健康及自身强壮具有重要作用,对存在睡眠剥夺的民众而言也有一定的好处。通过深入探究民众睡眠的完整过程后,研究人员发现,慢波睡眠的质量取决于机体大脑细胞或神经元内钙的活性。 东京大学的Hiroki Ueda教授指出,虽然睡眠是人类的基本生理功能,但我们对其机制仍然知之甚少。通过使用各种科学技术、计算机模

Thyroid:与分化型甲状腺癌转移相关的突变基因

虽然分化型甲状腺癌(DTC)的远处转移率很低,但转移是该疾病的常见致死原因。DTC患者中转移性肿瘤的基因改变,以及它们和原发肿瘤的关系仍知之甚少。因此研究者对DTC患者进行了一项研究,探究基因改变与原发性肿瘤远处转移的关系。该研究纳入了17对DTC患者原发肿瘤和远处转移病灶配对的标本,还纳入了另外2名患者的3份未配对转移性肿瘤标本。对样本进行测序分析,主要探究已知的与甲状腺癌相关的体细胞突变热点。

Neuron:新研究识别促进神经系统修复的特定基因网络

神经细胞损伤后能否再生取决于它们在体内的位置。周围神经系统中的神经细胞,比如胳膊和腿部的神经,损伤后至少在某种程度上可以恢复和再生。但中枢神经系统(大脑和脊髓)中的神经细胞,则完全无法恢复。 在最新在线发表于《Neuron》的研究中,加州大学洛杉矶分校(UCLA)领导的研究团队识别出一种能够促进小鼠模型中周围神经系统修复的特定基因网络和基因表达模式。研究人员发现,中枢神经系统没有这种网络。研
