Abstract
本发明公开了用于构建TARDBP基因突变的ALS模型猪核移植供体细胞的基因编辑系统及其应用。该基因编辑系统包含按照本发明所述方法制备的Cas9蛋白,针对TARDBP基因的gRNA以及含有TARDBP突变位点的单链Donor DNA。采用本发明构建并表达的Cas9高效蛋白联合体外转录的gRNA进行基因编辑,并对Cas9和gRNA的最佳用量配比进行了优化,配合合成的ssODN作为Donor DNA,最终获得靶标位点精确点突变的单细胞克隆比率高达22.5%,远高于常规的点突变效率(<5%)。所构建的TARDBP基因突变猪细胞可用于进行体细胞克隆,生产肌萎缩侧索硬化症模型猪。
Description
技术领域
本发明属于基因编辑技术领域,具体涉及CRISPR/Cas9系统及ssODN同源重组技术在构建TARDBP基因突变的肌萎缩侧索硬化症模型猪核移植供体细胞中的应用。
背景技术:
肌萎缩性脊髓侧索硬化症,又名肌萎缩侧索硬化症(Amyotrophic LateralSclerosis,ALS),是运动神经元疾病(Motor Neuron Disease,MND)的主要类型,俗称“渐冻人症”,其特征是脑和脊髓中的运动神经细胞(神经元)进行性退化。运动神经元控制着人体运动、说话、吞咽和呼吸时的肌肉活动,若其功能发生障碍,肌肉将逐渐萎缩退化,表现为肌肉逐渐无力以至瘫痪,说话、吞咽和呼吸功能减退,直至呼吸衰竭死亡。此病症未侵犯人体的感觉神经,所以并不影响患者的智力、记忆或感觉。病情的发展一般较迅速,从出现症状开始,平均寿命为3-5年,但因个体异质性波动较大。“渐冻人症”被世界卫生组织列为与艾滋病、癌症等并列的5大绝症之一,发病率大约为十万分之三,属于世界罕见病。
“渐冻人”协会国际联盟在2000年于丹麦举行的国际病友大会上确定每年的6月21日为“世界渐冻人日”,各地在这一天举行各类认识运动神经元疾病的相关活动,希望通过这种活动,引起人们对患有这种可怕疾病患者的重视和社会关爱。目前,ALS的病理生理机制尚不完全清楚,国内也尚无准确的ALS发病率的流行病学报道,但有关ALS的遗传因素影响已经得到广泛认可。约90%以上的ALS病例为散发性(sporadic ALS,SALS),余下病例为家族遗传性(familial ALS,FALS),已经确定超过30种基因和FALS有关。其中,最常见和研究最多的基因为ALS1(SOD1)、ALS10(TARDBP)、ALS6(FUS)、FTDALS1(C9orf72)等,它们和ALS的某些特定临床特征包括起病年龄、部位及生存期有关。
TDP-43是一个多功能的DNA和RNA结合蛋白,由TARDBP基因编码,在细胞内的RNA转录、选择性剪接及mRNA稳定性调节等过程中发挥功能。正常情况下,TDP-43在细胞应激环境下能参与形成应激颗粒,以应对细胞环境变化。应激颗粒是通过可逆的液液相分离聚集成的无膜结构,但是错误的聚集会导致不可逆的淀粉样蛋白沉淀。TDP-43蛋白在ALS和FTLD(frontotemporal lobar degeneration,额颞叶变性运动神经元疾病)患者细胞如神经元和神经胶质细胞内以淀粉样形式存在,已成为此两种疾病的主要病理标志性蛋白之一,另外在20-50%的阿尔茨海默病(Alzheimer’s disease,AD)患者中也发现了该蛋白的异常变化。已有研究发现在ALS病例中,约4%的FALS和1.5%的SALS是由TARDBP基因突变引起的,已鉴定出40多个TARDBP基因的突变,它们多集中于该蛋白C端的甘氨酸富集区,然而关于TDP-43蛋白如何造成神经元细胞死亡及其引起神经退行性疾病的细胞和分子机制尚不清楚。
研究由TARDBP突变导致ALS或其他神经退行性疾病发生发展的细胞和分子机制及研发相应的药物均需要在动物模型的基础上进行,目前常用的动物模型为小鼠模型,然而小鼠不论从体型、器官大小、生理、病理等方面都与人相差巨大,不能真实地模拟人类正常的生理、病理状态。而猪作为大动物,是人类长期以来主要的肉食供应动物,其体型大小和生理功能与人类近似,易于大规模繁殖饲养,而且在伦理道德及动物保护等方面要求较低,是理想的人类疾病模型动物。
基因编辑是近年来不断取得重大发展的一种生物技术,其包括从基于同源重组的基因编辑到基于核酸酶的ZFN、TALEN、CRISPR/Cas9等编辑技术,其中CRISPR/Cas9技术是当前最先进的基因编辑技术。目前,基因编辑技术被越来越多地应用到动物模型的制作上。
同源重组(HDR)是通过序列同源性交换DNA序列信息:即修复模板中包含所需插入片段,修复模板的两端则是与插入位点附近具有序列同源性的重组臂。过去通常使用双链DNA(dsDNA)作为修复模板,但最近的研究揭示了单链寡核苷酸脱氧核苷酸(ssODN)作为HDR供体模板的优越性。首先,ssODN作为供体模板比dsDNA模板的插入位点特异性高,dsDNA模板容易产生随机插入。其次,ssODN对同源重组臂的长度要求比dsDNA模板更短,单侧30~60个碱基的重组臂设计可以获得高效且稳定的HDR,相比类似的dsDNA模板,其提供的插入效率更高。第三,dsDNA容易被NHEJ修复途径合并,从而导致同源臂的复制或者dsDNA模板的部分整合,而ssODN就不易产生这种现象。另外,dsDNAs对培养的细胞是有害的,线型或者质粒dsDNAs的转染效率较低,并使细胞产生不良反应,而ssODN模板在这些方面就更有优势。
因此,本发明采用CRISPR/Cas9技术联合ssODN同源重组技术进行了TARDBP基因的点突变基因编辑,模拟ALS的自然发病遗传特征,并获得了TARDBP基因精确点突变的单细胞克隆,为后期通过体细胞核移植动物克隆技术培育ALS疾病模型猪奠定了基础。该模型猪将为研究ALS的发病机制及药物研发提供有力的实验工具。

本发明所述的基因编辑系统、所述的重组细胞在构建TARDBP基因突变的肌萎缩侧索硬化症模型猪中的应用。
与现有技术相比,本发明至少具有如下有益效果:
(1)本发明研究对象(猪)比其他动物(大小鼠、灵长类)具有更好的应用性。
大小鼠等啮齿类动物不论从体型、器官大小、生理、病理等方面都与人相差巨大,无法真实地模拟人类正常的生理、病理状态。研究表明,95%以上在大小鼠中验证有效的药物在人类临床试验中是无效的。就大动物而言,灵长类是与人亲缘关系最近的动物,但其体型小、性成熟晚(6-7岁开始交配),且为单胎动物,群体扩繁速度极慢,饲养成本很高。另外,灵长类动物克隆效率低、难度大、成本高。
而猪作为模型动物就没有上述缺点,猪是除灵长类外与人亲缘关系最近的动物,其体型、体重、器官大小等与人相近,在解剖学、生理学、免疫学、营养代谢、疾病发病机制等方面与人类极为相似。同时,猪的性成熟早(4-6个月),繁殖力高,一胎多仔,在2-3年内即可形成一个较大群体。另外,猪的克隆技术非常成熟,克隆及饲养成本也较灵长类低得多。因此猪是非常适合作为人类疾病模型的动物。
(2)本发明所构建的pET32a-T7lac-phoA:SP-TrxA-His-EK-NLS-spCas9-NLS-T7ter(简称pKG-GE4)载体,使用了能够高效表达目的蛋白的强启动子T7lac来进行目的蛋白的表达,用细菌周质蛋白碱性磷酸酶(phoA)的信号肽来引导目的蛋白分泌表达至细菌周质腔中,从而与细菌胞内蛋白分离,且分泌到细菌周质腔中的目的蛋白为可溶性表达。同时还采用硫氧还原蛋白TrxA与Cas9蛋白融合表达,TrxA能帮助所共表达的目的蛋白形成二硫键,提高蛋白的稳定性、折叠的正确性,增加目的蛋白的溶解性及活性。为了方便目的蛋白的纯化,设计了His标签,可以通过一步法Ni柱亲和层析纯化目的蛋白,极大地简化了目的蛋白的纯化流程。同时在His标签后设计了一个肠激酶酶切位点,便于切除所融合的TrxA-His多肽片段,得到天然形式的Cas9蛋白。利用带His标签的肠激酶酶切融合蛋白后,可通过一次亲和层析除去TrxA-His多肽片段及带His标签的肠激酶,得到天然形式的Cas9蛋白,避免了多次纯化透析对目的蛋白的伤害和损耗。同时,本发明也在Cas9的N端及C端分别设计了一个NLS位点,使Cas9能更有效地进入细胞核进行基因编辑。另外,本发明选择了E.coliBL21(DE3)菌株为目的蛋白表达菌株,该菌株可高效表达克隆于含有噬菌体T7启动子的表达载体(如pET-32a)的外源基因。同时,对于Cas9蛋白的密码子,本发明进行了密码子优化,使之完全适应表达菌株的密码子偏好,从而提高目的蛋白的表达水平。另外,本发明在细菌生长至一定数量后,再用IPTG在低温下诱导目的蛋白的表达,可避免目的蛋白过早表达对宿主菌生长的影响,低温下诱导表达也显著提高所表达的目的蛋白的可溶性。经过上述各项优化设计及实验实施,所得到的Cas9蛋白活性比商品Cas9蛋白有了极显著的提高。
(3)采用本发明构建并表达的Cas9高效蛋白联合体外转录的gRNA进行基因编辑,并对Cas9和gRNA的最佳用量配比进行了优化,配合合成的ssODN作为Donor DNA,最终获得靶标位点精确点突变的单细胞克隆比率高达22.5%,远高于常规的点突变效率(<5%)。
(4)利用本发明所得到的靶基因点突变单细胞克隆株进行体细胞核移植动物克隆可直接得到含靶标基因点突变的克隆猪,并且该突变可稳定遗传。
在小鼠模型制作中采用的受精卵显微注射基因编辑材料后再进行胚胎移植的方法,因其直接获得点突变后代的概率非常低(低于1%),需要进行后代的杂交选育,这不太适用于妊娠期较长的大动物(如猪)模型制作。因此,本发明采用技术难度大、挑战性高的原代细胞体外编辑并筛选阳性编辑单细胞克隆的方法,后期再通过体细胞核移植动物克隆技术直接获得相应疾病模型猪,可大大缩短模型猪制作周期并节省人力、物力、财力。
本发明为通过基因编辑手段获得类似人ALS疾病发展进程的TARDBP点突变模型猪奠定了坚实的基础,将有助于研究并揭示由TARDBP突变导致ALS的发病机制,并可用于进行药物筛选、药效检测、基因及细胞治疗等研究,能够为进一步的临床应用提供有效的实验数据,进而为预防和治疗人类ALS提供有力的实验手段。本发明对人类ALS疾病治疗药物的研发及临床前实验具有重大应用价值。

具体实施方式
实施例1原核Ca9高效表达载体(简称pKG-GE4)的构建
质粒pET32a-T7lac-phoA:SP-TrxA-His-EK-NLS-spCas9-NLS-T7ter(简称pKG-GE4,质粒图谱如图2)是以质粒pET-32a(结构示意图见图1)作为骨架进行改造而来,主要改造如下:①保留了TrxA蛋白的编码区域,可以帮助所表达的目的蛋白形成二硫键,增加目的蛋白溶解性及活性,但是在此序列之前加入碱性磷酸酶(phoA)的信号肽(SP)序列,该SP可以引导所表达的目的蛋白分泌至细菌的膜周质腔中,并可被原核周质信号肽酶酶切;②在TrxA蛋白编码序列之后增加His-Tag标签基团,可用于所表达的目的蛋白的富集;③在His-Tag标签下游增加肠激酶(EK)酶切位点DDDDK(Asp-Asp-Asp-Asp-Lys),纯化出的蛋白将在肠激酶作用下去除His-Tag标签和上游所融合的TrxA蛋白。④插入密码子优化后的适宜大肠杆菌BL21(DE3)菌株表达的Cas9蛋白的编码序列,同时在该基因的上游和下游均增加核定位信号编码序列(NLS),增加后期纯化出的Cas9蛋白的核定位能力。
pKG-GE4载体构建方法如下:

(3)全基因合成片段与骨架载体连接
将步骤(1)回收的骨架载体和步骤(2)全基因合成的序列重组得到质粒pKG-GE4,核苷酸序列见SEQ ID NO.1。SEQ ID NO.1中,第5121-5139位核苷酸组成T7启动子,第5140-5164位核苷酸编码Lac操纵子(lac operator),第5178-5201位核苷酸编码核糖体结合位点(RBS),第5209-5271位核苷酸编码phoA(碱性磷酸酶)信号肽(signal peptide,SP),第5272-5598位核苷酸编码TrxA蛋白,第5620-5637位核苷酸编码His-Tag标签,第5638-5652位核苷酸编码肠激酶酶切位点,第5656-5670位核苷酸编码SV40核定位信号(NLS),第5701-9801位核苷酸编码spCas9蛋白(其密码子已优化为适宜在大肠杆菌BL21(DE3)菌株中进行表达),第9802-9849位核苷酸编码nucleoplasmin核定位信号(NLS),第9902-9949位核苷酸编码T7终止子。
