Abstract
本发明涉及含有编码p185neu癌蛋白质的不同片段的序列的质粒,其能够诱导抗表达ErbB家族癌基因的肿瘤的免疫应答,及其药物组合物。
Description
本发明涉及含有p15neu-编码序列的质粒载体及其在抗肿瘤的DNA疫苗接种中的用途。根据本发明的质粒含有编码人类或大鼠癌蛋白质p185neu不同片段的序列,并且能够诱导抗表达ErbB家族癌基因的肿瘤的体液或细胞介导的免疫应答。
本发明还涉及含有所述质粒的药物组合物以及它们用于预防或治疗表达p185neu的肿瘤的用途。
发明背景
蛋白质p185neu是研究最多的肿瘤抗原之一,由于它存在于一些最常见的人类癌细胞膜上,所以它作为抗癌免疫治疗的靶标引起了人们极大的兴趣。
p185neu是在大鼠体内由原癌基因Her2/neu编码的膜受体,并且属于I类酪氨酸激酶受体(RTKs)家族,此家族还包括表皮生长因子受体EGF-R(ErbB-1)和其它相关受体(ErbB-3、ErbB-4)。这些受体与细胞增殖和分化有关(Hynes和Stern,1994BBA 1198:165),因此引起极大的生物学及临床兴趣。此受体由三个明确区分的结构域:胞外结构域、跨膜结构域和胞浆内结构域组成。p185neu与细胞内信号转导和细胞内通讯的机制的复杂网络有关,此所述机制调节增殖与分化过程(Boyle 1992Curr.Op.Oncol.4:156)。癌基因neu是按化学诱导的大鼠神经胶质胚细胞瘤(neuroglioblastoma)命名,从神经胶质胚细胞瘤首次分离癌基因neu。此活化的neu形式有一个点突变,导致“T”代替“A”,结果谷氨酸残基取代p185neu 644位的缬氨酸残基(Val644Glu)(Bargmann等人,Cell 45:649)。
人类neu同源基因ErbB-2也已经被分离鉴定,并证明大鼠HER2/neu受体和人类ErbB2都与EGFR有显著同源性(Coussens等人,1985,Science230:1132;Yamamoto等人,1986,Nature 319:230)。虽然大鼠序列中遗传突变导致组成型受体通过二聚化激活,但是在ErbB-2阳性人肿瘤中,观测到癌基因的异常表达(Di Marco等人,1990,Mol.Cell.Biol.10:3247;Klapper等人,2000,Adv Cancer Res,77:25),即使在极少数情况中,已经发现了激活点突变和异常剪接机制(Kwong等人,1998,Mol Carcinog 23:62;Xie等人,2000,J Natl Cancer Inst,92:412)。总体效应是相似的:基因扩增和转录水平的增加决定了过量的p185neu膜受体,结果活性二聚体增加,其在细胞内以配体独立的方式转导生长信号。最近报导的关于人类和大鼠p185neu细胞外区域的晶体结构显示此蛋白的特征在于具有刚性构象,其允许与其它的ErbB受体相互作用,不直接结合任何配体,并引发增殖信号转导(Cho HS等人,2003,Nature 421:756)。
正常情况下,人p185neu与器官发生和上皮生长有关;在胎盘形成和胎儿发育期间以高水平表达,而它在成人组织中则以非常低的水平存在(Press等人,1990,Oncogene 5:953)。
一些研究证明,人类p185neu过量表达与肿瘤性转化过程和肿瘤侵占的水平有关。已经描述了p185neu在肺(Kern等人,1986,CancerRes.50:5184)、结肠(Cohen等人,1989,Oncogene 4:81)、卵巢(Slamon等人,1989,Science 244:707)、腺癌以及在多种人乳腺癌(Slamon等人,1989,Science 244:707;Jardines等人,1993,Pathobiology 61:268)中的过量表达。
使得p185neu成为质粒疫苗接种的最佳靶标的基本特性是:a)它直接与细胞生长和癌发生有关,因此克隆变体由于肿瘤遗传不稳定性而失去了此抗原的表达,也失去了它们的致瘤力;b)它表达在细胞质膜上,这使它即使是在失去了主要组织相容性体系的表达的肿瘤细胞中也可以被抗体识别(Lollini P.和Forni G.2003,Trends Immunol,24:62)。
对活化的大鼠癌基因Her-2/neu转基因的小鼠(其自发产生p185neu阳性乳腺肿瘤)以及使用p185neu阳性可移植肿瘤系对鼠类模型进行的研究证明了预防和治疗癌变前损伤的可能性。具体关于大鼠活化的Her-2/neu基因转基因小鼠中乳腺肿瘤的预防,我们证明了与编码全长大鼠p185neu的质粒或者只编码胞外结构域的质粒(分泌抗原)相比,编码p185neu胞外结构域和跨膜结构域的质粒可以更有效地诱导体内保护(Amici A.等人,2000,Gene Ther.,7:703;Rovero S.等,2000,J.of Immunol.,165:5133)。Chen等人报道了相似的结果(1998,Cancer Res 58:1965)。其他作者证明不管是编码未改变的p185neu的质粒还是编码突变p185neu以除去它的酪氨酸激酶活性的质粒,在预防p185neu阳性细胞接种物引起的肿瘤发生中都是有效的(Wei WZ等人,1999,Int J.Cancer 81:748)。而且,缺乏负责通过内质网加工的信号(前导区,其决定p185neu抗原在细胞质中的定位)的质粒经证明同样有效。由不同质粒诱导的保护作用主要对于p185neu的膜表达的情况由体液免疫应答介导,对于细胞质定位的情况由T淋巴细胞介导的免疫应答介导(Pilon SA等人2001,J.of Immunol.167:3367)。然而,用诱导在细胞质和细胞膜中p185neu都过表达的质粒联合疫苗接种在对抗肿瘤生长的保护中更加有效(Piechocki MP等人,2001,J.Immunol.167:3367)。
因此,不同免疫应答机制之间的平衡可能尤其重要(Reilly等人,2001,Cancer Res.61:880)。而且,观察到用编码大鼠p185neu的胞外结构域和跨膜结构域的质粒接种,当细胞接种物过表达p185neu时,能够消灭直径为2mm的肿瘤块,这是免疫系统的许多不同的效应机制(T辅助细胞和T杀伤细胞、抗体、巨噬细胞、嗜中性粒细胞、自然杀伤细胞、Fc受体、γ干扰素和穿孔蛋白)实现的,所述效应机制协力排斥肿瘤(Curcio C.等人,2003,J.Clin.Invest.111:1161)。
发明描述
已经将编码人或人/大鼠嵌合p185蛋白质的多种构建体插入质粒载体并用于旨在防止肿瘤发展的免疫实验中。为了质粒构建,由ErbB2癌基因序列制备出人p185neu蛋白质的片段,其含有跨膜结构域和长度减少的胞外结构域的部分,或者其部分用大鼠Her-2/neu cDNA同源序列代替以构建嵌合质粒。
在接种过表达人p185neu的肿瘤细胞的小鼠中通过疫苗接种实验评估所得质粒。含有p185neu的截短形式的质粒诱导杀伤性T淋巴细胞和辅助T淋巴细胞介导的抗肿瘤反应性,而嵌合质粒诱导针对人和大鼠p185neu的抗体应答。
以体内实验结果为基础,挑选能够诱导细胞型和体液型强免疫反应的含p185neu序列的质粒。这些本发明的目的质粒含有编码p185neu片段的序列,此序列选自SEQ ID NO.1-14(人和大鼠p185neu参考序列可以分别以Gene Bank检索号M11730和X03362得到)。
根据本发明,p185neu编码序列可以插入适合人施用的任意质粒。除了编码序列,质粒还可以含有用于转录控制的功能元件,特别是置于编码序列上游的启动子,优选CMV启动子、起始和终止转录元件、选择标记,如氨苄青霉素或卡那霉素抗性基因;CpG基序、聚腺苷酸化位点或转录激活因子。转录控制元件应与载体在人体中的使用相容。在优选实施方案中,本发明的质粒含有至少4个CpG基序,优选地,至少8个CpG基序,最多80个CpG基序。细菌来源的CpG基序(ATAATCGACGTTCAA)诱导巨噬细胞分泌IL-2,其又诱导自然杀伤细胞分泌IFN-γ,从而激活T辅助淋巴细胞介导的应答(Chu R.S.等人,1997,J.Exp.Med.,186:1623)。因此,质粒序列中CpG基序的插入增强免疫应答。
在另一实施方案中,本发明提供了药物组合物,它含有一种或多种不同的如上定义的质粒及与之联合使用的可药用载体(vehicle)和赋形剂。此药物组合物为适合肠胃外施用的形式,优选地,为可注射溶液剂的形式,方便地用于DNA疫苗接种。DNA疫苗接种的原理和方法是技术人员已知的并且公开在例如,Liu MA 2003,J Int Med 253:402。
在另一个实施方案中,本发明提供了组合制剂,其含有至少两种,优选地,至少四种,更优选地,至少八种不同的质粒,用于同时、顺序或者单独施用于个体或患者。
根据本发明的质粒、组合物和制剂用于预防性或治疗性治疗处于患p15neu-阳性肿瘤危险中的个体,或者患有p15neu-阳性肿瘤的原发肿瘤、转移瘤或复发的患者。预防可以是主要的,此时肿瘤还没有表现出来,预防可以是次要的,此时肿瘤处在初始阶段作为癌前病变,预防可以是第三位的,此时肿瘤处于复发或转移过程。能从用本发明的质粒治疗中受益的肿瘤是那些上皮来源肿瘤的,特别是肺、卵巢和乳腺腺癌,更一般地,表达p18neu蛋白质的肿瘤。
发明详述
pCMV3.1质粒骨架的构建
为了构建编码人p185neu片段的质粒和嵌合质粒,使用pCMV3.1质粒骨架。将得自人类原癌基因ErbB2 cDNA的片段和得自大鼠原癌基因Her-2/neu cDNA的片段插入由限制酶DraIII(nt1531)和BsmI(nt189)除去1658bp片段的pCMV3.1(Invitrogen,米兰,意大利)中,所述1658bp片段含有复制起点f1、复制起点和早期SV40启动子、编码新霉素抗性的基因和SV40多腺苷酸化信号。与天然pCMV3.1相比,所得改造后的质粒(pCMV3.1)呈现出某些优势。实际上,质粒大小减小到3900bp和无关序列的除去有助于提高体内转染功效。
质粒pCMV3.1erbB2的构建
从质粒pSVerB2获得的人ErbB2 cDNA已经插入pCMV3.1的多克隆位点中限制位点HindIII和XbaI中。此质粒用于构建表达截短的p185neu的质粒和嵌合质粒。
含有序列4XCpG的质粒:pCMV3.1hECD-TM-4CpG和pCMV3.1hECD-TM-4noCpG的构建
从质粒pCMV3.1-erbB除去编码细胞质内结构域的序列后,制备编码原癌基因ErbB2胞外区和跨膜区的两种质粒。此过程包括首先进行限制性分析,用以鉴定存在于ErbB2 cDNA核苷酸序列中的独特位点。鉴定了酶AccIII(nt2195)所识别的一个独特位点,其位于跨膜结构域末端下游大约20bp处。
用以独特限制性酶切位点存在的酶AccIII和酶XbaI除去细胞质结构域。为了将识别为翻译终止信号的核苷酸三联体TAA重新插入ErbB2ECD-TM DNA的3’末端,我们使用两条合成序列,这两条序列由两条有义寡核苷酸(寡核苷酸#1、#3)和两条反义寡核苷酸(寡核苷酸#2、#4)组成,所述寡核苷酸它们的末端有限制性位点AccIII和XbaI。在这些合成的序列中,还存在着四个重复序列CpG和noCpG,后者用做阴性对照。将这两种新质粒命名为pCMV3.1hECD-TM-4CpG和pCMV3.1hECD-TM-4noCpG。
含在序列8XCpG的质粒:pCMV3.1H/NhECD-TM-8CpG和pCMV3.1H/NhECD-TM-8noCpG的构建
为了增加其他的无特异性免疫刺激,我们构建了含有4个免疫刺激性CpG序列的新的质粒骨架,命名为pCMV3.1H/N-4CpG。为达到这个目的,我们改进了pCMV3.1以便除去酶PmeI的两个限制性位点中的一个,并通过由两条有义(寡核苷酸#5)和反义(寡核苷酸#6)寡核苷酸组成的合成序列颠倒多克隆位点上存在的HindIII和NneI限制性位点。在此命名为pCMV3.1H/N的新质粒中,插入了两条合成的序列,此两序列由两条有义(寡核苷酸#7,#9)和反义核苷酸(寡核苷酸#8,#10)组成,并在唯一限制性位点XbaI和PmeI中含有CpG和noCpG序列的四个重复,从而获得了pCMV3.1H/N-4CpG和4noCpG质粒。此后,将DNA片段hECD-TM-4CpG和hECD-TM-4noCpG分别插入pCMV3.1H/N-4CpG和pCMV3.1H/N-4noCpG中,由此得到两种新的质粒,命名为pCMV3.1H/NhECD-TM-8CpG和pCMV3.1H/NhECD-TM-8noCpG。
含有人p185neu的第二个半胱氨酸结构域和跨膜结构域的质粒:pCMV3.1H/Nh2°cysECD-TM-8CpG的构建
人p185neu胞外结构域的特征是两个富含半胱氨酸的区域,称作第一和第二个半胱氨酸亚结构域(1st cys和2nd cys)。不像大鼠cDNA序列,其只含有胞外结构域中的一个位点BstEII(nt1250),该胞外结构域位于分隔1stcys和2nd cys的核苷酸区域中,ErbB2的胞外结构域的cDNA序列有两个BstEII限制性位点:除了与大鼠相同位置的位点(nt1372)外,另一个BstEII位点(nt963)存在于编码胞外结构域的1st cys部分中。用HindIII和BstEII消化质粒pCMV3.1H/NhECD-TM-8CpG,得到由来自胞外结构域的2ndcys、跨膜结构域、序列8CpG和质粒pCMV3.1H/N组成的DNA片段。然后使用有义寡核苷酸和反义寡核苷酸,通过酶促DNA扩增(PCR反应)将大鼠p185neu经内质网分泌的信号插入,所述有义寡核苷酸由识别T7RNA聚合酶的引物T7(寡核苷酸#11)(存在于pCMV3.1H/N多克隆位点的开始处)组成,所述反义寡核苷酸(寡核苷酸#12)在其末端具有BstEII位点。经纯化后,扩增的片段用限制酶HindIII和BstEII酶促消化,随后克隆,得到pCMV3.1H/Nh2°cysECD-TM-8CpG(图.1)。此质粒用于疫苗接种实验,将它与pCMV3.1H/NhECD-TM-8CpG比较。此后,制备了编码融合蛋白质的嵌合cDNA,此融合蛋白质是人序列的2nd cys和跨膜结构域(nt1372-nt2204)与大鼠序列的1st cys(nt1-nt1250)之间的融合蛋白质。通过分别来自大鼠和人cDNA的部分的融合重构完整蛋白质允许增强免疫应答。
含有大鼠p185neu的第一半胱氨酸结构域和人第二个半胱氨酸结构域及跨膜结构域(nt1-nt1250)的序列的嵌合质粒:
pCMV3.1H/N-r1°cys-h2°cysTM-8CpG的构建
不像大鼠cDNA序列,其只含有胞外结构域中的一个BstEII位点(nt1250),该胞外结构域位于分隔富含半胱氨酸的第一个和第二个区的核苷酸区域中,Erb2的胞外结构域的cDNA序列有两个BstEII限制性位点:一个在1372(nt)位,和大鼠序列中位置相同;另一个在963(nt)位上,即位于编码胞外结构域的1st cys的序列部分中。BstEII位点存在于大鼠cDNA结构域(1250nt)和人类cDNA(1372nt)中同一个位置上使得可以构建能够编码大鼠1st cys与人2nd cys之间的融合产物。事实上,用限制酶HindIII和BstEII消化pCMV3.1H/N-h2°cysTM-8CpG使得可以将编码大鼠p185neu分泌信号的DNA片段用编码大鼠1st cys的核苷酸序列替换,所述编码大鼠1st cys的核苷酸序列用同样的酶消化pCMV3.1rECD-TM-4CpG获得的。质粒pCMV3.1H/N-r1°cys-h2°cysTM-8CpG(图2)的产物由大鼠p18neu的422个氨基酸的部分和人p185neu的274个氨基酸的部分组成。此新质粒pCMV.1H/N-r1°cys-h2°cysTM-8CpG已用于免疫接种实验,实验中用pCMV3.1H/N-hECD-TM-8CpG做为比较项。令人惊奇地,编码嵌合蛋白的质粒在小鼠体内诱导针对表达人p185neu的肿瘤的完全保护作用(表)。此保护作用与pCMV3.1H/N-hECD-TM-8CpG诱导的保护作用相似。而且,对用两种质粒接种的小鼠血清的分析证明对人p185neu具有相似的抗体效价。
能够编码人p185neu胞外结构域和跨膜结构域的减短片段的质粒
构建编码人p185neu胞外结构域和跨膜结构域的减短片段的7种质粒,即:pCMV3.1H/NhECD1-TM-8CpG(-70个氨基酸);pCMV3.1H/NhECD2-TM-8CpG(-150个氨基酸);pCMV3.1H/NhECD3-TM-8CpG(-230个氨基酸);pCMV3.1H/NhECD4-TM-8CpG(-310个氨基酸);pCMV3.1H/NhECD5-TM-8CpG(-390个氨基酸);pCMV3.1H/NhECD6-TM-8CpG(-470个氨基酸)和pCMV3.1H/NhECD7-TM-8CpG(-550个氨基酸)。
这些片段中第一个片段编码的片段缩短70个氨基酸(缺失360bp)。所有其它的则逐个缩短80个氨基酸(缺失240bp)。
这些片段已经经DNA酶促扩增得到,该扩增使用末端具有NheI限制性位点的七条不同的有义寡核苷酸(寡核苷酸#13-#19),和能够识别存在于pCMV3.1的3’末端的多接头处名为“pCMV3.1/BGH反向引发位点”(830-850nt)的反义寡核苷酸(寡核苷酸#20)。用限制性酶NheI和PmeI酶促消化后,扩增产物克隆入先前获得的pCMV3.1H/N-neu前导区,将大鼠p185neu的内质网分泌信号插入限制性位点中。大鼠p185neu分泌信号的DNA片段是用引物T7(寡核苷酸#11)作为有义核苷酸,和在末端具有NheI位点的反义核苷酸(寡核苷酸#21)经酶促DNA扩增得到的。扩增得到的片段经过纯化和用HindIII和NheI限制性消化后,被克隆到用同样的酶消化的质粒pCMV3.1H/N中,得到pCMV3.1H/N-neu前导区。由于存在大鼠p185neu的内质网分泌信号,所以预计人p185neu不同截短形式的膜表达。编码截短形式的质粒pCMV3.1H/NhECD1-TM-8CpG(图3)、pCMV3.1H/NhECD2-TM-8CpG(图4)、pCMV3.1H/NhECD3-TM-8CpG(图5)、pCMV3.1H/NhECD4-TM-8CpG(图6)和对照质粒pCMV3.1H/NhECD-TM-8CpG都保护100%接种的小鼠对抗表达人p185neu的肿瘤细胞的致死性接种物(表)。质粒pCMV3.1H/N-hECD5-TM-8CpG(图7)保护60%动物,而质粒pCMV3.1H/NhECD6-TM-8CpG和pCMV3.1H/NhECD7-TM-8CpG(图8、9)对于表达人类P185neu的肿瘤细胞的致死性接种物没有保护作用(表)。不同的质粒表达的蛋白质产物没有通过内质网分泌。糖基化和内质网加工所必需的共有序列的缺乏,或-NH2末端氨基酸的缺失导致的构象改变可以解释膜中蛋白质产物的缺乏。因此,为了进一步验证不同截短形式的人p185neu胞外和跨膜结构域是否被正确表达,产生了编码以-NH2末端表位myc为特征的融合蛋白的新质粒。这些重组蛋白质被抗myc单克隆抗体所识别,因此,就可能用共焦显微术分析它们的表达和定位。
首先,已经产生了编码大鼠内质网分泌信号(neu前导区)和myc表位的新质粒。使用合成序列实施克隆,此序列由两端都具有NheI位点的有义(寡核苷酸#22)和反义(寡核苷酸#23)寡核苷酸组成。突变5’位中的NheI位点,从而一旦正确连接,此位点不被所述酶识别。我们因此得到了pCMV3.1H/Nneuleader-myc表位。用此质粒,在限制性位点NheI和PmeI中克隆了编码人p185neu截短形式的序列。随后用lipofectamine2000(Invitrogen,米兰,意大利)将质粒体外转染3T3 NIH成纤维细胞。48小时后,使用FITC缀合的抗myc单克隆抗体(Sigma-Aldrich Srl,米兰,意大利),用共焦显微术分析经转染的细胞。由此,证明了所有质粒编码的截短形式均定位在细胞质中。3T3 NIH成纤维细胞用质粒pCMV3.1H/NhECD-TM-8CpG平行转染,使用c-erbB2/c-neu Ab-3单克隆抗体(Oncogene,波士顿,美国)作为一级抗体,和FITC缀合的抗小鼠二级抗体(PharMigen,San Diego,CA),用共焦显微术进行分析。观察到人ECD-TM表达在膜上。用前述质粒的前四种质粒(pCMV3.1H/NhECD1-TM-8CpG、pCMV3.1H/NhECD2-TM-8CpG、pCMV3.1H/NhECD3-TM-8CpG、pCMV3.1H/NhECD4-TM-8CpG)所得到的结果证明细胞应答足够用于抗肿瘤防御。然而,已知细胞和体液应答的同时活化对于更有效的治疗是必要的(Rielly等人,2001,Cancer Res61:880)。正如前面段落已经陈述的那样,质粒pCMV3.1H/N-r1°cys-h2°cys-TM-8CpG编码的嵌合蛋白质可以100%的保护接种过的动物,并能在小鼠体内诱导强的体液应答。
嵌合质粒能够编码五种不同的人-大鼠嵌合p185neu
为构建编码嵌合蛋白质的质粒,我们选用了质粒pCMV3.1H/NhECD1-TM-8CpG、pCMV3.1H/NhECD2-TM-8CpG、pCMV3.1H/NhECD3-TM-8CpG和pCMV3.1H/NhECD4-TM-8CpG。这四种质粒可以100%保护被接种的小鼠对抗表达人p185neu的肿瘤细胞的致死接种物。质粒pCMV3.1H/NhECD5-TM-8CpG也被选用,即使它仅保护60%的经接种小鼠,因为所编码的蛋白质与质粒pCMV3.1H/Nh2°cysECD-TM-8CpG编码的蛋白质相比只有17个氨基酸不同,后者保护60%的经接种小鼠。我们可以假设,这17个氨基酸的肽序列对应于诱导有效免疫应答的重要表位。
DNA酶促扩增获得了编码大鼠p185neu部分的DNA片段。为扩增这些cDNA片段,使用都具有相同定位,即T7引物(寡核苷酸#11)的定位的6种寡核苷酸,而设计了识别适当位置的大鼠cDNA并且在它们的末端具有NheI限制性位点的5种反义寡核苷酸(寡核苷酸#24-#28)。扩增得到的片段经纯化和限制酶HindIII和NheI消化后,插入到经同样限制酶消化的相应质粒(pCMV3.1H/NhECD1-TM-8CpG、pCMV3.1H/NhECD2-TM-8CpG、pCMV3.1H/NhECD3-TM-8CpG、pCMV3.1H/NhECD4-TM-8CpG和pCMV3.1H/NhECD5-TM-8CpG)中。通过这种方法,我们得到了五种新质粒,其可以编码689个氨基酸的嵌合蛋白质,其中2个(Val-Ser)属于用来连接大鼠和人DNA的限制性位点NheI。这两个氨基酸的存在使得人和大鼠部分都是异种溶解的。
嵌合蛋白质不同于人p185neu缩短部分和大鼠p18neu增加部分。质粒pCMV3.1H/Nr73-hECD1-TM-8CpG(图10)编码大鼠p185neu胞外结构域的73个氨基酸和人p185neu的614个氨基酸。质粒pCMV3.1H/Nr73-hECD2-TM-8CpG(图11)编码大鼠p185neu胞外结构域的153个氨基酸和人p185neu的534个氨基酸。质粒pCMV3.1H/Nr233-hECD3-TM-8CpG(图12)编码大鼠p185neu胞外结构域的233个氨基酸和人p185neu的454个氨基酸。质粒pCMV3.1H/Nr313-hECD4-TM-8CpG(图13)编码大鼠p18neu胞外结构域的313个氨基酸和人p185neu的374个氨基酸。质粒pCMV3.1H/Nr393-hECD5-TM-8CpG(图14)编码大鼠p185neu胞外结构域的393个氨基酸和人类p185neu的294个氨基酸。用这五种新的质粒和作为阳性对照的质粒pCMV3.1H/N-r1°cys-h2°cys-TM-8CpG免疫小鼠得到了这些质粒编码的人/大鼠嵌合p185neu的膜表达的间接证据。所有接种的小鼠血清都含有抗人p185neu的特异抗体。而且,用编码五种不同嵌合蛋白质的质粒接种的动物也受到保护免于表达人p185neu的肿瘤细胞致死性接种物的影响。
实施例
实施例1-质粒pCMV3.1H/N-r1°cys-h2°cys-TM-8CpG的构建
为构建嵌合质粒pCMV3.1H/N-r1°cys-h2°cys-TM-8CpG,我们从质粒pCMV-ECD-TM开始,该质粒表达大鼠p185neu胞外结构域和跨膜结构域(Amici等人,2000,Gen Ther.,7:703)。质粒pCMV-ECD-TM用限制酶HindIII和XbaI(BioLabs,Beverly,MA)消化以从质粒骨架分离插入片段。

将与插入片段相应的带除去,用QiaQuick凝胶提取试剂盒(Qiagen,意大利)从凝胶洗脱DNA。
平行的,将其中DNA片段对应于大鼠p185ECD-TM的新质粒骨架(pCMV3.1H/N-4CpG)用相同的限制性酶消化并在琼脂糖凝胶上洗脱。
与大鼠ECD-TM相应的DNA片段和线性化质粒pCMV3.1H/N-4CpG用于通过连接反应获得pCMV3.1H/N-rECD-TM-4CpG。

菌株DH5α的转化:
感受态细菌细胞 100μl
连接产物 5μl
为了使质粒DNA穿透感受态细胞,将转化体系放置冰上40分钟,然后将其进行热休克(42℃1.5分钟,之后放置冰上2分钟)。
加入1ml LB生长培养基后,转化后的细菌细胞在37℃孵育1小时以恢复其生理状态。
细胞悬浮液以6000转/分钟离心1分钟,沉淀物重悬浮于100μlLB中。
细胞接种在含有选择性固体培养基(含有琼脂的LB+100μg/ml氨苄青霉素)的培养皿上,并在37℃生长一夜。氨苄青霉素允许含有质粒pCMV3.1H/N-rECD-TM-4CpG的细胞生长,所述质粒赋予了氨苄青霉素抗性。
所得克隆用碱裂解分析以挑选出含有重组质粒pCMV3.1H/N-rECD-TM-4CpG的那些克隆。
为了获得嵌合质粒pCMV3.1H/N-r1°cys-h2°cys-TM-8CpG,质粒pCMV3.1H/N-rECD-TM-4CpG用限制酶BstEII和XbaI消化以除去大鼠p185neu的第二个半胱氨酸结构域和跨膜结构域。同时,质粒pCMV3.1hECD-TM-4CpG用相同的酶消化以分离相应于人基因的第二个半胱氨酸亚结构域和跨膜结构域的DNA片段。

实施例2-体内试验
动物
约7周龄的Balb/cAnCr(H-2d)雌性小鼠用于所有实验中。
这些动物由Charles River Laboratories(Calco,MI,意大利)提供,生长在无菌条件中并按照欧洲共同体(European Community)的准则。
肌内施用后体内电穿孔
为避免胫骨肌肉不必要的收缩,每只小鼠都用腹膜内接种300μl的阿佛丁(avertine)麻醉,阿佛丁由将0.58g三溴乙醇(Sigma-Aldrich)和310μl叔戊醇(Aldrich)溶于39.5ml去离子水中制备。随后,所有小鼠在胫骨肌相应处剃毛以便接种。
用含有50μg DNA的40μl溶液在相应于两个胫前肌处接种动物。
在临用前制备含有DNA的混合液,按照F.Pericle博士(Valentis,Inc.The woodlands,德克萨斯,美国)的指示配制。此溶液含有1.25mg/ml质粒DNA,6mg/ml聚-L-谷氨酸钠盐(Sigma-Aldrich,S.r.l.,Milano,意大利),150mM氯化钠(Fluka,BioChemika,Buchs,瑞典)和不含内毒素的蒸馏水(Nucleare Free Water,Promega公司),最终体积为1mL。
在接种后约5分钟,所处理的区域用电穿孔仪Electro SquarePorator(T820,BTX,San Diego,CA,USA)进行电穿孔,应用两次电脉冲,强度为375V/cm2,每次持续25ms。通过使用彼此相隔3mm放置于每个爪子边上的两个方形钢电极应用经皮电脉冲。在接种肿瘤细胞前21天和7天,对每只动物用电穿孔进行2次基因免疫。
肿瘤细胞的接种
用含有2×105个D2F2/E2细胞的悬浮液接种小鼠。这些细胞来源于在BALB/C小鼠的增生泡状结中自发产生的乳腺肿瘤,并表达高水平的人p185。
肿瘤生长的体内评估
每周通过触诊评估肿瘤生长,用卡尺沿着两个垂直的直径测量肿瘤的尺寸。测定大于3毫米的瘤块即认为是肿瘤。
肿瘤生长从肿瘤接种后到100天,或者直到肿瘤生长到直径大于10mm,然后处死动物。
