mRN药物简介

基于mRNA的治疗,简单来讲就是利用化学修饰后的mRNA分子进入细胞质中,利用细胞质内的自有核苷酸进行转录表达,生成机体所需要的蛋白质。上世纪90年代,mRNA药效被初步证实,之后大量的精力投入到了mRNA药物的研发中。

mRNA药物开发的主要技术门槛在于稳定性和递送,若相关难点能够得以解决,mRNA药物就可作为蛋白质补充或替代疗法治疗相关疾病。尤其是随着癌症基因测序和抗原表位发现等技术的发展,mRNA药物也可用于针对肿瘤患者的个性化治疗,并具有巨大的应用潜力。目前在mRNA肿瘤药物开发领域进展较快的企业主要是Moderna、BioNTech和CureVac。

二、mRNA合成过程所需原料

(一)国内外mRNA X冠疫苗的合成工艺

BioNTech/辉瑞、Moderna和艾博生物mRNA疫苗的合成工艺如下:

1BNT162b2–BioNTech/辉瑞

三核苷酸cap1类似物((m27,3′-OGpppm2'-OApG)(TriLink)和N1-甲基假尿苷-5′-三磷酸(m1ψTP)(ThermoFisherScientific)取代尿苷-5′-三磷酸(UTP)的存在下,通过T7RNA聚合酶对DNA进行纯化和体外转录。

总结:转录采用一步法,帽子类似物作引物;甲基假尿苷取代尿苷。

2mRNA-1273–Moderna

利用优化的T7RNA聚合酶介导的转录反应在体外合成了编码序列优化的mRNA,尿苷被N1-甲基假尿苷*取代。转录后,使用牛痘苗封盖酶(新英格兰生物实验室)和痘苗2′O-甲基转移酶(新英格兰生物实验室)将Cap1结构添加到5’端。通过oligodT亲和纯化纯化mRNA,通过切向流过滤将缓冲液交换到pH5.0的醋酸钠中,无菌过滤,并在-20°C下冷冻,直到进一步使用。

总结:转录采用两步法,需要加帽酶的参与,甲基假尿苷取代尿苷。

3ARCoV-艾博生物

mRNA在体外使用T7RNA聚合酶介导的转录从质粒ABOP-028GENEWIZ)的线性化DNA模板中产生,该质粒编码SARS-CoV-2的密码子优化RBD区域,并包含5’3‘的未翻译区域(UTR)和一条poly-a尾巴,以未修饰的NTP作为原料和T7聚合酶体外进行mRNA的合成,使用了牛痘加帽系统(VacciniaCappingSystem(Novoprotein)进行加帽。

总结:转录采用两步法,需要加帽酶的参与。

(二)mRNA制备过程原料

mRNA制备过程需要用到的主要原料包括质粒DNA模板、一系列酶(主要为7种酶)以及底物核苷酸等;

1、模板DNA所需原料:质粒

DNA模板生产,主要是质粒的生产。编码抗原的DNA模板,通过质粒转染到大肠杆菌大规模体内表达,最后提取和纯化携带目的序列的质粒,即得到DNA模板。目前质粒的生产提取和纯化工艺很成熟,可以自建生产线或者外包出去,例如辉瑞自建质粒生产工厂,大部分mRNA企业外包,Moderna和国内企业目前是外包。

制备mRNA质粒的要求:质粒用于制备mRNA,这类DNA本身不属于APIDNA需要按照GMP规范进行,GMP质粒要求生产设备必须是专用的、符合GMP规范且配备洁净间

2mRNA体外转录所需原料:一系列酶+核苷酸底物

mRNA疫苗的研发与生产需要一系列酶的参与:mRNAT7聚合酶、无机焦磷酸酶、RnaseInhibitor、加帽酶以及2′O-甲基转移酶、Poly(A)聚合酶和DNAase等主要7种酶。

2.1转录过程所需要的酶

RNA聚合酶体系RNA聚合酶是体外转录mRNA的关键酶。

T3T7SP6RNA聚合酶分别对T3T7SP6噬菌体启动子具有高度的特异性。将目的基因序列克隆到T7SP6启动子下游的多克隆位点中,以克隆的DNA为模板体外合成相应的RNA

T7RNAPolymeraseT7RNA聚合酶)【78MRNA-1104】高度特异识别T7启动子序列,以含有T7启动子序列的单链或双链DNA为模板,以核甘酸(NTP)为底物,合成与启动子下游的单链DNA互补的RNA

无机焦磷酸酶78MRNA-1109加入无机焦磷酸酶,增加RNA产量。无机焦磷酸酶(PPase)可催化无机焦磷酸盐水解生成正磷酸盐,可以为蛋白、RNADNA的生物合成反应提供动力,促进产物的生成。在工业化生产mRNA疫苗的时候会产生大量的无机焦磷酸盐,为了保证mRNA疫苗高效生产,可以添加无机焦磷酸酶,可解除生成的无机焦磷酸盐对反应体系的抑制。

RNase抑制剂【78MRNA-1103/78DA10001】:防止RNA的降解。少量RNaseRNA制备过程中引入,会导致RNA的降解,污染可能通过实验过程中使用的枪头、试管(离心管)和其他试剂引入。通常使用RNase抑制剂作为减少和控制此类污染物的预防措施。

RNase抑制剂能与RNaseA形成1:1复合体,抑制RNase活性,在mRNA疫苗研发和生产过程需要保持mRNA的稳定性以保证疫苗高质量的生产。

2、转录所需材料核苷酸和修饰核苷酸

mRNA疫苗研发中常进行假尿嘧啶化修饰,尿嘧啶修饰是丰富RNA修饰,一般由尿苷的异构化产生,mRNA的假尿嘧啶化修饰主要有三个功能:改变密码子、增强转录本稳定性和应激反应应答。

3、加帽和加尾:共转录加帽/模板加尾,转录后加帽/加尾

真核生物体内会对转录形成的mRNA进行加帽,即在mRNA5’端添加一个甲基化的鸟苷酸帽子(m7GPPPN结构),从而保护mRNA免遭核酸外切酶的攻击以增加mRNA的稳定性,并且协助mRNA与核糖体的结合以促进翻译起始。生物体内的帽子结构有cap0cap1cap2三种形式,牛痘病毒加帽酶能够在mRNA5’端添加cap0帽子,再使用甲基转移酶处理即可得到cap1帽子。

此外,5'帽子还参加mRNA前体的剪接,参与mRNA3'末端多聚腺苷酸化,保证mRNA在细胞质中的稳定运输。

加帽需要的酶:牛痘病毒加帽酶

可以将7-甲基鸟苷帽结构(m7GpppCap0)加到RNA5末端,大幅提高mRNA的稳定性和启动mRNA的翻译。牛痘病毒加帽酶能够在一小时之内对mRNA进行加帽,效率接近100%

mRNA疫苗研发生产过程中,mRNA加帽效率和加帽mRNA稳定表达的效率对疫苗的工业化生产有重大的影响。牛痘病毒加帽酶体系加帽的mRNA在细胞内的表达效率大于帽子类似物mRNA的表达效率。

加尾酶:Poly(A)聚合酶

Poly(A)聚合酶可以催化ATPAMP的形式依次掺入到RNA3末端,即在RNA3末端加多聚A尾。Poly(A)尾巴能够增强mRNA的稳定性、提高翻译起始效率、引导mRNA出核。

主要用到的酶:

1)牛痘病毒加帽酶【78MRNA-1105】:

2)痘苗2′O-甲基转移酶【78MRNA-1106

3Poly(A)聚合酶

加帽酶非常昂贵,如何替代加帽酶?

一步法合成mRNA疫苗产品的加帽可以在mRNA的体外转录过程中通过掺入帽子序列实现,这种加帽技术会将加帽序列反向加在mRNA上,在反应体系中加入5’帽类似物,可以省一个加帽酶,以及减少纯化步骤,一定程度上降低成本(尤其是节省了昂贵的加帽酶成本),但相对应地,产量较之两步法(加帽酶参与)减少,因为加帽酶的加帽效率更高。

4、消除DNA模板:需要DNA酶【78MRNA-1110

合成后的产物可能会有DNA残留,在疫苗开发阶段,残留的去除是关键的步骤,以减少下游纯化难度并增加产品的纯度。需要用DNA酶(DNAase将残留的DNA模板进行消除,在mRNA疫苗生产的过程中对DNA的残留控制非常严格格。

摘要化学修饰使mRNAs的制备具有更高的稳定性和翻译活性。在本研究中,我们探索了mRNA体和聚(A)尾中5′、3′磷酸二酯键的化学修饰如何影响真核mRNA的生物学特性。为了获得修饰和未修饰的体外转录mRNAs,我们使用ATP和
在α-磷酸(包含O-to-S或O-to-BH3替换)和三种不同的RNA聚合酶-SP6、T7和聚(A)聚合酶处修饰的ATP类似物。为了验证ATP类似物在ATP存在下的掺入效率,我们开发了一种液相色谱-串联质谱(LC-MS/MS)方法,用于基于转录物*降解为5′-单核苷酸的定量评估修饰频率。该方法还估计了平均聚(A)尾长度,因此为建立mRNA的结构-生物学特性关系提供了一个通用工具。我们发现,与未修饰的mRNA相比,在聚(A)尾中含有硫代磷酸基团的mRNA更不易被3′-dedenylase降解,并在培养细胞中有效表达,这使它们成为有用的研究工具和未来基于mRNA的疗法发展的潜在候选。

由于应用分析方法的分辨率差,导致ITE长度增加,这又因多聚(A)尾异质性而变得复杂(Jalkanen等人,2014年)。最高分辨率测序方法,如TAIL-seq(Chang等人。
PAlso-seq(Subtelny等人2014年;Liu等人2019年)和FLAM-seq(Legnini等人2019年)提供了关于核苷酸序列、聚(A)尾长度和腺嘌呤修饰存在的信息。质谱分析
通过直接注入分析或结合色谱技术成功地用于RNA(包括mRNA)分析(Kowalak等人,1993年;
Gong和McCullagh 2014;Rose等人,2015年;韦策尔和林巴赫2016;Studzinska等人,2017年;Beverly等人,2018年;Lobue等人,2019年;Calderisi等人,2020年)。这种强有力的技术提供了有关RNA结构和功能的信息
组成,包括聚(A)尾长。尽管这是一种高分辨率和敏感的方法,但由于多电荷态和相关光谱的复杂性,长mRNA的分析可能很困难(Muddiman)
等人,1996年)。
在这项研究中,为了能够分析P-mod mRNA,我们开发了一种新的液相色谱-串联质谱(LC-MS/MS)方法,该方法能够同时量化修饰的磷酸化核糖核酸的数量-
双酯键和mRNA中聚(A)尾平均长度的估计(图1)。随后,我们应用该方法对携带硫代磷酸或磷酸硼砂修饰的IVT P-mod RNA进行了表征-
三种不同的RNA聚合酶可以使细胞大小不同。最后,对LC–MS/MS表征的P-mod mRNA进行了体外研究,以评估其对酶促脱烯基化的敏感性,并在培养细胞中评估磷酸二酯修饰对蛋白质表达的影响。我们瞥见了P-mod RNA的合成孔径雷达,并确定了与高效蛋白质表达兼容的修饰模式。

ozbiosciences mRNA产品简介

ozbiosciences mRNA产品简介


mRNA HIGH QUALITY PRODUCTS CUSTOM SERVICE 

优点#1:它不需要核摄取来表达,因为mRNA的翻译发生在细胞质中。事实上,核递送(通过核膜)是转染慢细胞或非分裂细胞的主要途径之一,因此,mRNA转染对这一目的特别有吸引力。

优点2:这种方法不是综合性的。与pDNA相反,mRNA不能导致遗传

优点#3:非常适合难以转染的细胞。mRNA比DNA有几个优点,可以更容易地对原代和难以转染的细胞进行基因修饰。除了mRNA没有整合到宿主基因组中的风险之外,mRNA转染是细胞周期独立的,特别适合于缓慢分裂的细胞,如内皮细胞或树突状细胞1。

mRNA的益处

-无需核摄取-蛋白质直接在细胞质中表达

比DNA转染更快的蛋白质表达

-无基因组整合

Dye-labeled mRNA

Synthetic mRNA is at the cutting-edge of nucleic acid-based therapeutics. Unlike DNA plasmids and viral vectors, mRNA does not require a nuclear localization signal and it carries negligible risk for genomic integration. However, delivery methods are still evolving and little is known about how they affect mRNA localization and trafficking, which ultimay influence translation and function. To aid in this discovery, TriLink has expanded its offerings to include fluorescent dye-labeled mRNA. This allows for the direct visualization of the mRNA through the incorporation of labeled NTPs. 

Cyanines are fluorescent dyes that are commonly used for life science applications. Cyanine-labeled NTPs incorporate efficiently into RNA transcripts via T7 polymerase. Importantly, cyanine5-labeled mRNA has also been shown to translate.

CleanCap™ Cyanine 5 FLuc mRNA is designed for the analysis of mRNA delivery and translation efficiency. The FLuc mRNA will express a luciferase protein, originally isolated from the firefly, Photinus pyralis. FLuc is commonly used in mammalian cell culture to measure both gene expression and cell viability. It emits bioluminescence in the presence of the substrate, luciferin. When labeled with cyanine 5, FLuc mRNA can be directly visualized. CleanCap™ Cyanine 5 FLuc mRNA is an ideal molecule to determine mRNA delivery and localization independent of translation.

Cyanine 5 is a synthetic fluorescent dye with maximum excitation and emission wavelengths of 650 nm and 670 nm respectively. TriLink’s CleanCap™ Cyanine 5 FLuc mRNA is transcribed with Cyanine 5-UTP:5-Methoxy-UTP at a ratio of 1:3. Substitution in this ratio results in mRNA that is easily visualized and can still be translated in cell culture. Translation efficiency correlates inversely with Cyanine 5-UTP substitution. 

This mRNA is capped using CleanCap™, TriLink's proprietary co-transciptional capping method, which results in the naturally occuring Cap 1 structure with high capping efficiency. It is polyadenylated, modified with 5-methoxyuridine and optimized for mammalian systems. It mimics a fully processed mature mRNA.

Antigen mRNA for Vaccines and Immunotherapy

mRNA offers several advantages over traditional plasmid and viral-based approaches:

  • mRNA boasts a superior safety profile. As a transient carrier of genetic information, it is metabolized naturally and poses little to no risk of genomic integration. Additionally, no inactivated viruses or pathogens are needed.
  • mRNA serves the dual purpose of expressing the desired antigen as well as acting as an adjuvant.
  • mRNA triggers a more diverse immune response. Because the mRNA encoded epitopes are intracellular, they are recognized by the immune system in an MHC class-independent manner.
  • mRNA can more readily transfect difficult-to-transfect cell types because it functions in the cytoplasm. DNA vaccines can be limited by lack of access to the nucleus.
  • mRNA manufacturing is easily scalable. Because mRNA transcription is carried out compley in vitro, to hundreds of millions of vaccine doses with a lead time of as little as a few weeks. This allows for rapid deployment of a new antigen during pandemics.
  • mRNA is easily customizable. The ease of manufacturing makes it a viable option for personalized treatments.

Genome Editing mRNA

Plasmids and viral vectors have traditionally been used in genome editing to express the required proteins inside cells or an organism. However, editing DNA carries a risk. Double stranded DNA breaks catalyze insertion of DNA at the cut site. At some substantial frequency, the protein expression vectors can integrate, which can lead to continuous expression of the nuclease or a previously silent sequence.

Now mRNA is being used in genome editing to transiently express the required proteins. With no risk of insertional mutagenesis, it is a powerful tool. Additionally synthetic mRNA, which mimics fully processed, capped and polyadenylated mRNA, can be produced in large quantities by in vitro transcription and modified to reduce innate immune stimulation.

Zinc-finger Nuclease mRNA (ZFN mRNA)

Zinc-finger nucleases (ZFNs) were the first widely applicable site specific genome editing tools. Recently, several studies have shown that ZFNs can have off-target effects at non-targeted chromosomal sites that are similar in sequence to the intended target site. For this reason, there is a move to transient ZFN expression using mRNA based vectors. TriLink’s custom mRNA transcription service includes ZFN mRNA. Request a quote today!

Cas9 mRNA expresses a version of the Streptococcus pyogenes SF370 Cas9 protein (CRISPR Associated Protein 9). Cas9 functions as part of the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) genome editing system. In the CRISPR system, an RNA guide sequence targets the site of interest and the Cas9 protein is employed to perform double stranded DNA cleavage.

Cas9 mRNA encodes the Cas9 protein with an N and C terminal nuclear localization signal (NLS). The incorporation of two NLS signals within the mRNA increases the frequency of delivery to the nucleus, thus increasing the rate of DNA cleavage. Additionally, a C terminal HA epitope tag aids detection, isolation, and purification of the Cas9 protein.

This mRNA is capped using CleanCap™, TriLink's proprietary co-transciptional capping method, which results in the naturally occuring Cap 1 structure with high capping efficiency. It is polyadenylated, substituted with a modified uridine and optimized for mammalian systems. It mimics a fully processed mature mRNA.
