Description
技术领域
本发明属于生物与新医药技术领域,具体属于一种Ndufs1基因在治疗心梗后心衰中的应用和相关产品。
背景技术
在全球范围内,心血管疾病是最常见的死亡原因。心力衰竭是大多数心血管疾病的终末期表现,其长期预后较差,其5年死亡率超过一些常见癌症。在过去的20年中,心肌梗死一直是心力衰竭的最常见原因。在心梗发生期间,血液供应的突然中断或减少导致心肌细胞死亡或使剩余存活心肌细胞功能障碍。心梗后细胞凋亡和心肌纤维化是不良心肌重构的重要病理特征。虽然目前介入和药物策略的进步已经为心梗患者带来了较好的临床结果,但心梗后心力衰竭的发病率和死亡率仍然很高。因此,寻找并确定新的治疗靶点非常重要。
心脏收缩和舒张需要持续供应ATP,其中大部分来自线粒体中的氧化磷酸化。线粒体复合物I是线粒体呼吸链的起始酶和最大的酶,负责从NADH到辅酶Q10的电子转移,并与质子从基质转运到膜间隙的过程相耦合。哺乳动物复合体I由45个亚基组成;14个核心亚基中有7个由核基因编码。Ndufs1是由核基因编码的最大核心亚基,是八个铁硫链的一部分,负责NADH的氧化。质子跨线粒体内膜易位产生电化学梯度,驱动复合体V中的ATP产生。作为同时产生ATP的副产品,活性氧也会在几个线粒体复合体中产生,主要是复合体I。之前的一项研究表明,神经元中的Ndufs1超低导致耗氧量受损,线粒体活性氧增加;星形胶质细胞中上调的Ndufs1也减少了活性氧的产生。在从患有Ndufs1突变的患者身上获得的皮肤成纤维细胞中,发现了高水平的氧化应激,伴随着复合物I活性的降低、耗氧量的降低和糖酵解的增加。作为线粒体电子传递链(ETC)的起点,Ndufs1是ATP和活性氧产生的双重“引擎”,并在多种疾病的代谢重编程、氧化应激和细胞凋亡中发挥重要作用。心脏是一个高耗能、富含线粒体的器官。Ndufs1在人类心脏中高度表达。然而,Ndufs1在心脏病中的作用及其潜在机制尚不清楚。
腺相关病毒(AAV)是一种线性单链的DNA病毒,是基因治疗的重要工具,具有表达时间持久、安全性高、免疫原性低等优势,已有大量的临床前研究和临床研究正在开展。不同血清型的AAV具有不同的组织特异性,可以实现组织特异性的基因递送,逐渐成为一种理想的基因治疗载体。

3)开头和结尾单下划线部分为酶切位点DNA碱基序列(均为6个碱基)。
6.质粒抽提
将测序正确的菌液转接于10ml含相应抗生素的LB液体培养基中,37℃培养过夜,用天根无内毒素质粒小提中量试剂盒进行质粒抽提,抽提合格的质粒进入下游流程。详细操作步骤如下:
(1).收集过夜培养的菌液于标记好的5ml离心管,12000rpm,离心2min收菌;
(2).弃上清,加入250μl细胞重悬液,充分振荡,使菌块悬浮均匀;
(3).加入250μl细胞裂解液,再加入10μl蛋白酶K,上下颠倒5-6次,轻轻混匀;静置1-2min,致使菌体裂解澄清;
(4).加入350μl中和液,上下颠倒混匀,使蛋白完全析出,冰浴静置5min;
(5).10000rpm离心10min,弃蛋白,收集上清于另一干净无菌的1.5ml EP管;
(6).12000rpm离心5min,同时准备标记好的回收柱,将上清转移至回收柱中,12000rpm离心1min,弃下层废液;
(7).加入600μl预先配置好的漂洗液,12000rpm离心1min,弃下层废液,重复一次,12000rpm空离2min,进一步除去残留的漂洗液;
(8).在超净台中将回收柱转移至新的1.5ml EP管中,静置10-20min,自然晾干;
(9).往回收柱中加入95μl Nuclease-Free Water,静置2min,12000rpm离心2min,收集样品做好编号,电泳、测定浓度,筛选出符合要求的纯度较高的质粒。
7.AAV病毒包装(因为本研究主要针对的是心肌细胞,建议使用AAV9型病毒)
(1)上述重组表达质粒同pHelper(携带腺病毒来源的基因)和pAAV-RC(携带AAV复制和衣壳基因)共转染AAV-293细胞(购自上海吉凯基因公司)(提供AAV复制和包装所需的反式作用因子)。转染2到3天后重组AAV在AAV-293细胞中组装完成,该细胞中会产生基于AAV的Ndufs1过表达载体。
(2)从被感染AAV-293细胞中收集AAV病毒颗粒,一般AAV颗粒会富集在AAV-293细胞中,所以收集上述细胞而后裂解,使其释放AAV颗粒到上清液中可以回收大部分的AAV颗粒。这一步得到的病毒上清液的随后用于感染各种哺乳动物类细胞系的感染实验。同时上清中的病毒也可以浓缩保留。
8.病毒滴度检测
采用定量PCR法检测病毒滴度,病毒滴度为:1.16×1013v.g./ml。
二.将含有Ndufs1过表达载体的病毒通过胸腔注射的方法导入小鼠心脏
选取4周龄雄性C57小鼠,实验前将小鼠胸前毛发脱去,在2%异氟烷麻醉作用下,将小鼠固定在操作台上。按照每只小鼠注射病毒总量为1x1011vg。病毒用生理盐水稀释,每只小鼠注射体积为50ul。剪开胸前皮肤约1cm,用微量注射器插入小鼠胸腔缓慢注射,注意不要扎入心脏。
本发明也可通过尾静脉注射或者心肌多点原位注射将含有Ndufs1过表达载体的病毒小鼠导入体内。
三.功能学及组织学实验验证:基于AAV9的Ndufs1过表达载体在改善心梗后心脏功能方面的作用
1.小鼠心梗(MI)模型
将小鼠分为4组,包括假手术组、心梗组、心梗+对照病毒组和心梗+Ndufs1过表达组,AAV9病毒注射一个月后进行心梗手术。小鼠用异氟醚(1%-2%)麻醉。通过左胸切口将小鼠心脏快速挤出胸腔。为了诱发心梗,用丝线缝合左前降支(LAD)冠状动脉(6-0)。缺血区的变白和心电图的变化是手术成功的重要参考。假手术对照小鼠接受相同的外科手术,无需结扎冠状动脉。
2.超声心动图
使用Vevo 2100超声系统在M模式下进行经胸超声心动图检查。
实验前用脱毛膏去除小鼠胸毛。然后用2%异氟醚麻醉小鼠并放置在温暖的加热垫上。在M模式下测量心脏功能,并在长轴和短轴视图中对每只小鼠的心脏进行成像。左心室收缩内部尺寸(LVID)和左心室舒张内部尺寸(LVIDd)是使用Vevo 2100软件通过间接测量获得的。通过进一步分析获得射血分数(EF)、左轴缩短率(FS)和其他超声心动图参数。
如图4所示,纵坐标射血分数和左轴缩短率都代表心脏收缩功能,分为4组,假手术组和心梗组比较表示心梗后心功能下降,心梗+对照病毒组和心梗+Ndufs1过表达病毒组比较后说明Ndufs1过表达后提高了心脏功能,证实心脏特异性过表达Ndufs1可显著缓解心梗后(4周)心脏功能障碍。
3.组织学染色
小鼠心脏样本用4%多聚甲醛固定过夜,石蜡包埋,切成5μm厚的切片。进行Masson三色染色以评估心脏胶原蛋白含量并确定梗死面积。梗塞面积被评估为总梗塞周长除以总左心室周长。使用ImageJ软件进行分析。
如图5所示,心梗后会出现纤维组织增多,与对照病毒组相比,Ndufs1过表达组明显纤维组织减少,心梗面积减少,证实心脏特异性过表达Ndufs1可显著减少心梗后(4周)的梗死面积和心肌纤维化。
4.蛋白质印迹
将结扎线下方的心脏组织用RIPA缓冲液裂解。蛋白质(25μg)在SDS-PAGE凝胶上分离,转移到聚偏二氟乙烯(PVDF)膜上,用5%牛奶封闭,并在4℃下与一抗孵育过夜。在室温下将膜与HRP偶联的二抗孵育1小时后,在化学发光系统上检测条带。使用LabImage软件分析和量化免疫印迹条带强度。GAPDH用作内参对照。
如图6所示,将GAPDH抗体用作内参对照,说明所有组蛋白上样量是基本一致的;Ndufs1过表达病毒带有Flag标签,用Flag抗体检测,第一行黑色条带中只有AAV-Ndufs1组能检测到蛋白条带,证实基于AAV9的过表达Ndufs1的病毒载体效果显著。
如图7所示,cleaved caspase3是细胞凋亡的关键标志物,与对照病毒组相比,Ndufs1过表达组明显减少了改蛋白的表达,证实过表达Ndufs1可显著减少心梗引起的细胞凋亡。
