近日,一项刊登在国际杂志Scientific Reports上的研究报告中,来自北海道大学的研究人员通过研究发现,关键的性别决定基因或许能在缺失Y染色体的哺乳动物机体中继续发挥作用,该研究对于理解性别分化的分子机制或将提供新的思路。

在很多胎盘哺乳动物(placental mammals)机体发育过程中,Y染色体能够诱导雄性分化,性别决定基因SRY存在于Y染色体中,而且其能够诱导其它调节性基因来抑制雌性的分化,而奄美刺鼠(Tokudaia osimensis)却是个例外,其机体中缺少Y染色体,当然SRY基因也就不存在了,但研究者比较好奇的是为何在奄美刺鼠中雄性的分化依然会继续发生呢?

研究人员通过进行基因图谱绘制从而确定了奄美刺鼠基因组中性别相关基因的染色体位点,随后他们将奄美刺鼠的核苷酸和氨基酸序列同其它小鼠、大鼠进行对比,利用培养细胞进行研究,研究人员检测了这些性别相关基因被调节的分子机制。

此前研究中,研究人员对SRY基因进行了分析研究,该基因能够开启一系列调节性基因的表达,比如Sox9和AMH基因,这些基因在雄性分化过程中都扮演着重要的角色,本文中研究者通过研究发现,尽管奄美刺鼠机体中没有SRY基因,但这些调节性基因依然能够被正常开启正常发挥作用,同时在其它胎盘哺乳动物中也能发挥相应的作用。

研究者Kuroiwa教授指出,我们推测在奄美刺鼠机体中有一种未知的基因替代了SRY基因扮演着类似该基因的角色,在整个进化过程中,哺乳动物机体的Y染色体能够通过减少携带基因的数量来明显缩小自己的体积,有些科学家认为,在未来某个时间点Y染色体会彻底消失,而研究者说道,我们希望基于当前的研究结果,能够帮助我们理解不依赖Y染色体及其进化方向的机体性别进化发生的机制和原理。

Science得出惊悚结论:抽烟会让男性丢失Y染色体

来自瑞典乌普萨拉大学等处的研究人员发表了题为“Smoking Is Associated with Mosaic Loss of Chromosome Y”的文章,指出有抽烟习惯的男性比非烟民的男性,Y染色体丢失的几率要高三倍。这一发现也许解释了对于大部分癌症来说,为何男性比女性患癌和癌症死亡率几率都要大,而且抽烟为何对男性的影响,要比对女性的影响大。这一研究成果公布在12月5日Science杂志

10年临床积累,欧洲Y微缺指南再度跟新

日益恶化的环境和快速的都市生活让无精、少精、弱精、精子畸形导致不育的年轻男性越来越多。Y染色体微缺失的分子诊断是少精子症和无精子症男性不育患者的常规基因检测项目。自1999年以来,欧洲男科学协会和欧洲分子遗传实验质控作网(EMQN/EAA)一直致力于提高Y染色体微缺失分子诊断质量,并出版了Y染色体微缺失分子诊断指南,提供了一套客观的检测质量评价实验方法。经过10年不断地临床积累,2013年9月19

Human Genetics:Y染色体损失影响阿尔茨海默氏症风险

一项新的研究表明,随着年龄的增长,男性血液细胞中的Y染色体会逐渐损失,这可能会增加老年痴呆症的患病风险。在该项研究中,研究者们对3,200多人的相关信息进行了研究,研究发现,阿尔茨海默氏症患者的血细胞中Y染色体损失量是正常人群的近三倍。更重要的是,“Y染色体损失”的老年男性在未来八年内,将会面临更高的阿尔茨海默氏症患病风险。专家表示,该项研究并不能证明:Y染色体损失直接引起了阿尔茨海默氏症,只能说

白银连环杀人案告破, Y染色体检测功不可没!

据公安部刑事侦查局官方微博消息,8月26日,自1988年起连续在14年间强奸、杀害多名女性的犯罪嫌疑人高某在甘肃省白银市落网。高某对犯罪事实供认不讳,甘蒙“8·05”系列强奸杀人残害女性案成功告破。 1988年至2002年,甘肃省白银市白银区先后发生多起强奸残害女性的系列杀人案件,首案距今已有28年之久。期间,内蒙古自治区包头市昆都仑区也发生过类似案件。犯罪分子作案手段十分残忍,不仅强奸

AGHG:缺乏Y染色体更易得阿尔茨海默症

本周有研究人员在欧洲人类遗传学会议提出,男性红细胞缺乏Y染色体更容易患阿尔茨海默症。研究人员希望,在未来这些发现可能有助于帮助筛查阿尔茨海默症患者并及早采取预防和治疗措施。约有500万名美国人患有阿尔茨海默症,相当于65岁以上的民众中有1/9的老人患有该病。预计到2050年,共有1400万名美国人患有该病。 尽管阿尔茨海默症患者数目众多,但研究人员尚未能了解其背后的分子机制,对相关风险因素也知之甚

Nat Genet:Y染色体丢失使男性患癌风险升高

根据瑞典乌普萨拉大学遗传学家Lars Forsberg博士领导的研究团队开展的一项新研究发现,血细胞发生Y染色体丢失的男性更可能罹患癌症和早逝,该研究发现可能有助新的筛查机制产生。相关研究结果公布于2014年美国人类遗传学学会 (ASHG) 年会,并完善了该团队此前的相关研究。 Y染色体丢失和癌症之间的这种关联性,可能有助于解释,男性为什么比女性寿命短,同时罹患性别非特异性肿瘤的比例更高。
