实施例1
vRIC-seq文库的制备、SARS-CoV-2结构解析、基于RNA结构设计siRNA及功能验证
根据已发表文献(Zhaokui Cai,Changchang Cao,Lei Ji,etc(2020).RIC-seqfor global in situ profiling of RNA–RNA spatial interactions.Nature,582,432~437)中的RIC-seq实验方案,根据图1所示流程构建SARS-CoV-2病毒颗粒的vRIC-seq文库。对测序数据进行分析后推断出SARS-CoV2的高级结构(图2)、二级结构(图3),根据此结构设计特异靶定SARS-CoV-2单链RNA区的siRNA,发现这些siRNA能够有效抑制SARS-CoV-2感染Vero细胞,可对目前流行各种SARS-CoV-2突变株基因组RNA进行切割。具体步骤如下:
1.取两个eppendorf 1.5-ml离心管,分别加入150μl ConcanavalinA磁珠,将离心管放在磁力架上,待溶液澄清后,用移液枪吸去上清,加入500μl结合溶液(20mM HEPS-KOHpH 7.9,10mM KCl,1mM CaCl2,1mM MnCl2),用枪轻轻吹打混匀10次,将离心管放在磁力架上,待溶液澄清后,用移液枪吸去上清。重复上述洗涤过程1次。加入400μl结合溶液、100μl灭活病毒颗粒,重悬ConcanavalinA磁珠。室温孵育10分钟。
2.将离心管放在磁力架上,待溶液澄清后,用移液枪吸去上清,磁珠用结合溶液洗四次,每次用量为600μl,用600μl PBST溶液(1×PBS,0.1%Tween 20)洗一次。
3.磁珠用1ml PBST溶液重悬,加入27μl 37%(质量/体积)甲醛,用移液枪上下吹打10次混匀。将离心管放在旋转混匀仪上,以20rpm室温旋转混匀10分钟。加入50μl 2.5M甘氨酸,用移液枪上下吹打10次混匀。将离心管放在旋转混匀仪上,以20rpm室温旋转混匀5分钟。
4.透化处理、微球菌核酸酶处理、pCp-biotin标记步骤参考已发表文献(ZhaokuiCai,Changchang Cao,Lei Ji,etc(2020).RIC-seq for global in situ profiling ofRNA–RNA spatial interactions.Nature,582,432~437),其中1×PNK溶液、1×PNK+EGTA溶液和Hight-salt溶液中的NP-40替换为0.1%(体积/体积)Tween 20。
5.近端连接前的FastAP处理与PNK处理合并为一步PNK处理,其中反应缓冲液为50mM imidazole-HCl pH 6.4、10mM MgCl2、10mM DTT。根据已发表文献(Cameron,V.,andUhlenbeck,O.C.(1977).3’-Phosphatase activity in T4 polynucleotidekinase.Biochemistry 16,5120-5126.),T4 PNK在上述缓冲液中同时具有较高的磷酸酶和激酶活性。
6.经RNA纯化和文库构建后,使用Illumina HiSeq X Ten测序仪对文库进行PE150双端测序。
7.根据已发表文献(Zhaokui Cai,Changchang Cao,Lei Ji,etc(2020).RIC-seqfor global in situ profiling of RNA–RNA spatial interactions.Nature,582,432~437)中的数据分析流程,对测序得到的原始数据进行前处理,随后利用分析流程(https://github.com/caochch/RIC2Structure)重构出SARS-CoV-2的二级结构(图3)和三级结构(图2)。
8.根据图1中b结果所示,97.3%的测序数据比对到SARS-CoV-2的基因组。表明ConA磁珠成功捕获SARS-CoV-2病毒颗粒。证明本发明中使用的ConA磁珠能够有效捕获病毒颗粒。
9.根据SARS-CoV2二级结构,选取位于单链区的RNA片段作为靶标,基于已发表文献(Lagana,A.,Shasha,D.,and Croce,C.M.(2014).Synthetic RNAs for GeneRegulation:Design Principles and Computational Tools.Front Bioeng Biotechnol2,65.)中的原则设计siRNA,一共设计了120条siRNA,siRNA正义链的核苷酸序列如SEQ IDNO.1~SEQ ID NO.120所示,反义链序列如SEQ ID NO.121~SEQ ID NO.240所示。

11.siRNA转染Vero细胞:利用Invitrogen公司Lipofectamine RNAiMAX试剂将siRNA转染至24孔板内的Vero细胞(8×104cells/孔)。转染siRNA的细胞在生物安全等级3(P3+)实验室中感染SARS-CoV-2(MOI=0.05),细胞由Opti-MEM培养基在37℃培养1小时后,移除含有病毒的培养基并用新鲜Opti-MEM培养基洗一次,然后在维持培养基(OPTI-MEM培养基含有1%(质量/体积)BSA和1%(体积/体积)青霉素/链霉素)中培养24小时。
12.RNA样品提取:为了检测上清中病毒含量,收集100μl含有病毒的培养基上清,病毒RNA利用TRIzol LS试剂(公司为:Invitrogen,货号为:10296028)进行提取并经过Direct-zolTM RNA MiniPrep试剂盒(公司为:ZYMO RESEARCH,货号为:R2050)纯化。为了检测细胞中病毒RNA丰度,利用Trizol试剂(公司为:Invitrogen,货号为:15596026)提取感染SARS-CoV-2病毒的Vero细胞总RNA。
13.荧光定量PCR检测上清和细胞中病毒含量:为了检测上清中病毒含量,利用TaqMan Fast Virus 1-Step MasterMix(Thermo Fisher Scientific,货号为:4444432)进行TaqMan RT-PCR分析,实验操作按照试剂盒说明书。选择的靶标基因SARS-CoV-2N蛋白。
所用的探针及引物序列为,探针(FAM-SEQ ID NO.243-BHQ):5’-FAM/CAGCGCTTCAGCGTTCTTCGGAATGTCGC/3’-BHQ,上游引物(SEQ ID NO.244)为:5’-AACACAAGCTTTCGGCAGAC-3’,下游引物(SEQ ID NO.245)为:5’-ACCTGTGTAGGTCAACCACG-3’。
为了检测细胞中病毒含量,感染病毒细胞总RNA经RQ1 RNase-free DNase(Promega,货号为:M6101)处理后,由MMLV反转录酶(Promega,货号为:M1701)利用oligo dT(20)引物反转录成cDNA;利用HieffqPCR SYBR Green MasterMix(YEASEN,货号为:11203ES08)进行qPCR分析,选取的靶标基因为SARS-CoV2 RdRp,上游引物(SEQ ID NO.246)为:5’-CAAATTCTATGGTGGTTGGCACA-3’,下游引物(SEQ ID NO.247)为:5’-GGCATGGCTCTATCACATTTAGG-3’,选取的内参基因为Vero GAPDH,上游引物(SEQ ID NO.248)为:5’-GTCTCCTCTGACTTCAACAGCG-3’,下游引物(SEQ ID NO.249)为:5’-ACCACCCTGTTGCTGTAGCCAA-3’。所用TanMan探针委托上海生工生物工程公司合成,所用引物委托华大基因公司合成。
结果如图4~5和表1所示,其中Mock为空白对照,未感染的细胞;TaqMan RT-PCR分析结果表明,相对于对照组siRNA,siRNA-1、siRNA-2、siRNA-3、siRNA-4、siRNA-5和siRNA-6对病毒拷贝数的抑制率为别为82%、99%、96%、98%、99%和95%。RT-qPCR分析结果表明相对于对照组siRNA,siRNA-1、siRNA-2、siRNA-3、siRNA-4、siRNA-5和siRNA-6对细胞中病毒丰度的抑制率为别为84%、99.6%、99.4%、99%、99.6%和64%。用靶向单链区域的siRNA转染后,上清液中的SARS-CoV-2拷贝降低至背景水平;且两条以上的siRNA组合可以切割目前流行的所有SARS-CoV-2突变株;SARS-CoV-2感染后,用靶向单链区域的siRNA处理的Vero细胞的存活率要高于靶向双链区域的siRNA处理的细胞,因此单链特异性siRNA可高效抑制SARS-CoV-2,促进细胞存活。
