Nat Genet:基因可显示你首次做爱的时间

2016-04-26 佚名 生物谷

关于DNA双螺旋结构的四个基本(A、T、C、G)分别用粉色、橙色、紫色和黄色等颜色来编码。 超过380,000人的DNA研究发现了一个相当惊人的人类基因的作用:有助于确定你第一次做爱的年龄。 如家庭稳定,青少年压力和人格类型等因素是所有已知影响青少年是否选择性行为的原因。 根据剑桥大学Ken Ong称,“基因有实质性的影响,遗传因素可以解释人们开始做爱的时代有大约25%的差异。” 例如

关于DNA双螺旋结构的四个基本(A、T、C、G)分别用粉色、橙色、紫色和黄色等颜色来编码。

超过380,000人的DNA研究发现了一个相当惊人的人类基因的作用:有助于确定你第一次做爱的年龄。

如家庭稳定,青少年压力和人格类型等因素是所有已知影响青少年是否选择性行为的原因。

根据剑桥大学Ken Ong称,“基因有实质性的影响,遗传因素可以解释人们开始做爱的时代有大约25%的差异。”

例如基因可能影响一些因素如青春期的到来,以及你是否拥有一个冒险的个性。据该研究的作者称,两性性成熟的平均年龄从1880年的18岁下降至1980年的12.5岁。

科学家们指出当代儿童营养和较大的个体的变化同接触干扰荷尔蒙的化学物质有关。

Ong和研究人员在英国健康研究中分析了125,000多名参与者,并指出38号基因变异与他们第一次发生性行为的年龄有关。

他们反复核对冰岛241,000名和美国20,000名参与者,总样本量超过380000人的基因数据集。

“我们发现,从1950年代到1980年代,遗传因素影响的大小在几十年的成长中保持不变,这表明遗传因素与广泛的文化和社会态度相关。”Ong说。

他们发现,许多基因变异也与其他生殖特征相关,如出生第一个孩子时的年龄,以及生育子女的数量。

这项研究发表在《自然遗传学》杂志上。以前的研究已经表明,开始做爱的人在年轻的时候更有可能在学校表现不佳,身体和心理等方面处于亚健康状态。

性早熟与患糖尿病,心脏病和某些癌症密切相关。但迄今为止,大多数研究集中在青少年性行为的社会文化原因层面上。研究小组表示,希望研究结果将有助于识别和帮助孩子倾向于遗传因素,否则,他们就会误入歧途。

CRISPR彩虹:同步实时追踪细胞内七个基因组位点

在一项新的研究中,来自美国马萨诸塞大学医学院的研究人员利用CRISPR/Cas9开发出一种新的被称作CRISPRainbow(CRISPR彩虹)的技术,这一技术允许科学家们标记和追踪活细胞中多达7个不同的基因组位点。这一标记系统将是一种宝贵的工具用于实时研究基因组结构。相关研究结果于2016年4月18日在线发表在Nature Biotechnology期刊上,论文标题为“Multiplexed l

Circulation:爱吃咸,是基因作祟?

为什么有人口重,饭菜少放盐就吃不下去?这可能与基因有关。英国一项最新研究发现,如果实验鼠缺失一个基因,就会表现得特别爱吃咸,并随之出现高血压症状。 爱丁堡大学研究人员在美国《循环》杂志上报告说,对实验鼠进行基因修改,去除部分鼠脑细胞中一个名为Hsd11b2的基因(指的是11βHSD2基因在大脑条件性敲除t (Hsd11b2.BKO)),这些实验鼠变得非常爱吃咸。11β-羟基类固醇脱氢酶2(1

PLOS Genetics:唇腭裂发生的新基因被发现

PLOS Genetics:科学家发现唇腭裂发生的新基因 非综合征性唇腭裂是一种常见的出生缺陷,病因较多且复杂。其最常见的类型是唇裂(nsCLP),伴或不伴有腭裂(nsCLO)。虽然遗传因素在人类唇腭裂的发生中起着重要作用,但是遗传因素在腭裂发生过程中的重要性却并不清楚。本研究中,研究人员从三个大型队列研究中提取了遗传和临床数据进行荟萃分析,并确定了染色体15q13上的一个区域与唇腭裂的发生之间密

AHA:你知道QT间期延长综合征么?

许多幼儿和青年人患有遗传性心脏疾病,表面看起来没有疾病,但是有时却会为他们打来突发性致命性的打击,因此研究人员试图寻找一种方法以检测没有症状但是却可能突然发生致命性疾病的民众。肯塔基州大学生理学副教授Brian Delisle博士指出,每年至少有数千名儿童和年轻人死于长QT综合症(LQTS)。LONG-QT综合症(LQTS)通常是一种常规染色体显性遗传疾病,定位于染色体11上的LQT1发生突变,导

JMCB:基因编辑猪可分泌人胰岛素

中国科学院广州生物医药与健康研究院赖良学课题组,利用精确基因编辑技术对猪胰岛素基因进行了无痕定点修饰,使猪胰岛素基因编码生产人胰岛素,建立了完全分泌人胰岛素的基因编辑猪。相关成果日前在线发表于《分子细胞生物学杂志》。 目前,对糖尿病的治疗包括胰岛素注射和胰岛移植。利用猪胰岛进行异种移植治疗糖尿病已取得良好进展。但猪与人相比,胰岛素蛋白存在一个氨基酸的差异,这使猪胰岛素在人体中的降血糖效价较
