甘氨酸,简单逆转衰老相关线粒体缺陷
衰老过程可以延迟甚至逆转?日本筑波大学的Jun-Ichi Hayash教授领导的研究团队最近发现至少在人类细胞系中确有如此可能。他们还确认了两种特殊的,能够调节最小和结构最简单的氨基酸—甘氨酸生成的基因部分参与了衰老的过程。这篇研究发表在最近的ScientificR eports上。 在许多物种(包括人类)中,线粒体功能异常是衰老的标志之一。这种理论来源于线粒体在细胞中扮演的能源站角色,它通过细胞呼吸过程产生的能量,为细胞供能。线粒体DNA损伤会使线粒体DNA改变或者突变。而这些变化的积累与寿命的降低[查看]

技术iBOLT,特异定位控制蛋白功能
一种新的技术可以更容易地定位和抑制细胞中特定的酶和其他蛋白质,并能通过光来任意开启和关闭这一调节。该方法为研究人员提供在天然细胞环境下研究蛋白质的功能的另一种工具。这篇研究在线发表在最近的Nature Chemistry。 在这项研究中,英国剑桥大学医学研究分子生物学实验室的Jason W. Chin和他的同事通过有选择地束缚小分子抑制剂到靶蛋白使得酶的活性被抑制。他们在这过程中使用到了他们之前发表的一种技术,应用了在细胞中发现的含有紧密烯烃和炔基非天然氨基酸的特殊基因编码蛋白。因此研究人员能够迅速和明确使用与嗪[查看]

铁蛋白和老年痴呆有关系?!
近日,一篇发表于国际杂志Nature Communications上的研究论文中,来自墨尔本大学的一项研究表明,高水平的铁蛋白或许和个体轻度认知损伤向阿尔兹海默氏症过渡直接相关。 文章中研究人员对91名认知正常的个体、144有轻度认知损伤的个体及67名阿尔兹海默氏症个体进行了长达7年的研究,研究结果显示,在那些轻度认知损伤个体的脑脊髓液中较高水平的铁蛋白或许和其向阿尔兹海默氏症转换直接相关,而铁蛋白和ApoE4基因的存在存在强相关性,ApoE4基因是熟知的阿尔兹海默氏症风险基因。 James Pickett博[查看]

DNA环状分子的自主复制
生物系统中存在很多的自主复制的例子。然而,人工制造这样的生物系统的自主复制系统却是相当困难,这是因为生物系统很复杂。在其他领域,人类可以创造某些自我复制系统,比如磁场系统以及模块化机器人等等。我们很少将这些人造的自我复制系统和生物系统中的自我复制系统进行比较。因而,如果能从理论上将人工的自主复制系统和生物细胞系统中的复制进行比较,这对于设计新型自主复制系统具有很大意义。其中,细胞中的DNA分子就是一个很好的切入点。基于其可以进行相互识别的特性,即DNA分子可以完成自组装和复制。 最近,韩国科学家们的研究证明,[查看]

老年痴呆靶向性疗法新希望
近日,一项发表于国际著名杂志Nature Structural and Molecular Biology上的研究论文中,来自伊利诺伊大学的科学家们通过研究确定了一种存在于大脑斑块细纤维中的特殊分子结构,该分子结构或是阿尔兹海默氏症发病的标志,这种分子名为β淀粉样蛋白-42,其对神经细胞具有毒性,而且被认为可以刺激疾病的级联反应。 理解纤维中β淀粉样蛋白-42的氨基酸长链形式的物质结构,对于揭示β淀粉样蛋白如何进行不正确地折叠以及在大脑中积聚形成毒性斑块非常重要。研究者Yoshita[查看]

老年痴呆的早期生物标记物:嗅觉障碍
嗅球处神经纤维缠结是阿尔茨海默病(AD)的早期病理表现。为明确嗅觉障碍在预测未来认知功能下降与AD痴呆中的实用性,来自哥伦比亚大学的Devanand教授开展了一项前瞻性观察研究,证实嗅觉损害不仅可预测“健康”人群的认知受损,还能早期预测轻度认知功能下降(MCI)发展为AD痴呆的可能性,该研究发表在近期的Neurology杂志。 该研究在纽约北麦哈顿的一个多民族社区人群中进行,共纳入1037例认知功能正常的受试者。研究者采用宾夕法尼亚大学嗅觉鉴定试验(UPSIT)对受试者进行嗅觉测试,UPS[查看]

中国科学家发现抗击H7N9禽流感病毒新抗体
近日,国际学术期刊nature communication在线发表了中国医学科学院和北京协和医学院研究人员关于应用单克隆抗体治疗H7N9禽流感病毒的最新研究进展,这项研究对于H7N9禽流感病毒预防和治疗,预防H7N9禽流感病毒大流行具有重要意义。 2013年2月,H7N9禽流感病毒亚型在中国华东地区出现,随后不久出现人感染H7N9病毒的情况,人感染H7N9禽流感会引起发热,咳嗽,有痰等急性呼吸道传染病症状,并造成重症肺炎,严重者可导致死亡。H7N9禽流感病毒的爆发严重威胁公众健康,但目前预防和控制人感染H7N9禽[查看]

干细胞如何记住自己的身份?
干细胞具有强烈的身份认同感。例如,从毛囊住所处取出干细胞,将它们置于培养基中培养,这些细胞仍然会保持真实的自我。在过渡状态下等待一段时间后,一旦将它们移植回皮肤,这些培养细胞能够再生出毛囊以及其他的皮肤结构。然而人们并不清楚这些干细胞(以及身体其他部位的干细胞)是如何在特殊的环境中保持生成新组织及愈合伤口的能力的。 来自洛克菲勒大学的一项新研究发现一个蛋白Sox9主导控制了细胞的可塑性。在发表于3月10日《自然》(Nature)杂志上的一篇研究论文中,该研究小组将Sox9描述为是一个“先锋因子&rdq[查看]

如何选择NGS自动化系统?
大规模NGS应用带来不仅仅是技术上的革新,相对传统更加复杂和精细操作,注定了这一技术将会更多地依赖自动化设备来完成。作为临检机构和近期崛起的众多第三方检测公司,在将NGS设备收入囊中之后,必然要考虑开始自动化样品制备系统的投入。只有将整个样品准备流程通过可靠的系统来完成,才能真正配得上是高质量的NGS检测流程。 ★ 那么问题来了,什么才是一套称职的自动化系统? 作为一套符合标准的NGS样品制备系统,最基本的要求就是能够提供符合标准的文库DNA,以浓度和片段大小作为考核的标准。 而决定这一切的是试[查看]

中国科大发现新型非编码RNA
最近,中国科学技术大学单革教授实验室在国际知名杂志《自然-结构和分子生物学》(Nature Structural & Molecular Biology)发表研究性论文,报导了其实验室发现的一类新型非编码RNA以及此类非编码RNA的功能和功能机理。 非编码RNA是一大类不编码蛋白质而在细胞中起着调控作用的RNA分子。单革教授实验室发现了一类新型的环状非编码RNA,在这类环状RNA中,内含子没有被除去、而是被保留在环形RNA当中,因此这类RNA被作者命名为外显子-内含子环形RNA(EIciRNA)。该文研究[查看]

投过论文的朋友应该都知道,一般情况下审稿人的名字是保密的,但论文作者的名字审稿人是知晓的。如今,Nature打算推行双盲审稿,这样审稿人便不会知道论文的作者,也会减少很多偏见。 从2015年3月份开始,Nature(《自然》)与自然旗下月刊,将提供一个替代传统的同行评议,即双盲审稿。作者可以在审稿时要求隐瞒名字和所属单位,通过双盲形式的同行评议,可能有助于审稿的客观与公平。目前,这个过程是单盲:评审是匿名的,但他们知道作者的身份。 替代传统的同行评议过程中经常提出。有人建议全面开放的评论,其中既有作者和审稿人的[查看]
