Description
技术领域
本发明一般涉及采用宿主细胞产生人α-半乳糖苷酶A(rhα-Gal A)的方法,并且涉及从包含污染宿主细胞蛋白质的材料中纯化由此产生的所述rhα-Gal A的方法。更具体地,本发明涉及通过在无血清培养基中培养产生rhα-Gal A的哺乳动物细胞来产生rhα-Gal A的方法,以及,采用柱色谱(包括染料-亲和柱色谱)从培养物上清液纯化由此产生的rhα-Gal A的方法,所述方法实现高产量,并且达到高纯度以允许该纯化的蛋白质作为医药药物直接使用。
背景技术
α-半乳糖苷酶A(α-Gal A)是一种溶酶体酶,其具有水解糖脂和糖蛋白的末端α-半乳糖基键的活性。三己糖神经酰胺,其包含三个己糖部分,是α-半乳糖苷酶A的底物之一,并且接受该酶在其末端己糖部分处水解。人α-Gal A表达为包含429个氨基酸的前体肽,其中N末端的31个氨基酸构成信号肽。该前体经加工成成熟肽,其在移除该信号肽之后剩下的部分由398个氨基酸组成,并且,一对成熟肽分子容易形成同二聚体,只要条件允许,其即为人α-Gal A的酶活形式。人α-Gal A具有包含甘露糖-6-磷酸残基的寡糖链,并且能通过甘露糖-6-磷酸受体被靶向至溶酶体。
法布瑞氏病是X连锁的遗传性溶酶体贮积病,其由编码α-Gal A的基因的遗传异常所致。该酶活性的缺乏造成三己糖神经酰胺在多种组织中的累积,导致肾损伤、血管扩张性疣和心血管异常,包括心室扩大和二尖瓣闭锁不全。
在上世纪60年代已知晓,在患有法布瑞氏病(Fabry's disease)的患者的组织中几乎检测不到或仅能微弱地检测到α-半乳糖苷酶A的酶活。因此,已推测编码α-Gal A的基因的一些遗传异常应是法布瑞氏病的病因。基于该推测,已通过如下方式进行了针对法布瑞氏病的α-Gal A替代治疗(replacement therapy):将从人血浆或脾提取并纯化的α-GalA输注给所述患者,获得如下证实结果:α-Gal A替代治疗可降低患有法布瑞氏病的患者血液中三己糖神经酰胺的水平(见NPL 1、NPL 2、NPL 3)。因此,人们认定了α-Gal A酶替代治疗对于法布瑞氏病而言一定是具有前景的。然而,α-Gal A替代治疗的实践应用受到该酶供应缺乏的高度限制。
在1986年,分离了编码人α-Gal A的基因(见NPL 4),进一步地,在1988年,报到了通过采用转化有人α-Gal A表达载体的CHO细胞来表达并产生rhα-Gal A的方法(见NPL 5)。利用重组技术,这些发现使得以大规模产生人α-Gal A并利用该酶作为用于法布瑞氏病的酶替代治疗的药物成为可能。还在昆虫细胞中表达了rhα-Gal A(PTL 1)。
此外,报道了一些用于纯化rhα-Gal A的方法,其包括采用疏水柱色谱、肝素琼脂糖柱色谱、羟基磷灰石柱色谱、阴离子-交换柱色谱,和凝胶过滤柱色谱(PTL 2、PTL 3)。尽管已显示PTL 2或PTL 3中所描述的用于纯化的方法获得的rhα-Gal A的纯度充分地高,并不认为其能完全适用于人类应用。原因在于,待输注给患者的任何药物均必须不含污染物,具体而言,例如,源自所用宿主细胞的蛋白质,无论PTL 2还是PTL 3均没有显示纯化的rhα-Gal中是否余留有这样的污染物。此外,据报道,用于纯化rhα-Gal A的方法包括,按顺序使用阴离子-交换柱色谱、疏水柱色谱、采用对磷酸基团具有亲和性的材料作为固相的柱色谱、阳离子-交换柱色谱,和凝胶过滤柱色谱(PTL 4)。然而PTL没有提及rhα-Gal A的宿主细胞蛋白质污染。
目前,包含rhα-Gal A作为活性成分的法布瑞氏病的医药药物已在市场上以商品名例如ReplagalTM和FabrazymeTM出售。

发明内容
技术问题
针对上述背景,本发明的一个目的在于:提供以在无血清培养基中培养产生rhα-Gal A的哺乳动物细胞开始的,产生和纯化重组人α-半乳糖苷酶A(rhα-Gal A)的方法。
本发明的另一个目的在于,提供用于从包含污染物宿主细胞蛋白质的培养物上清液纯化rhα-Gal A的方法,通过包括染料-亲和柱色谱的柱色谱,以实现高产量,并且达到高纯度以允许该纯化的蛋白质作为医药药物直接使用。

本发明的发明人发现,在无血清培养基中培养产生rhα-Gal A的细胞的上清液中所含的rhα-Gal A,可从包含污染宿主细胞蛋白质的该上清液纯化至极高纯度,并且同时获得极高的产量,通过使rhα-Gal A经过包括阴离子-交换柱色谱、疏水柱色谱、采用对磷酸基团具有亲和性的柱的色谱、阳离子-交换柱色谱、染料-亲和柱色谱,和凝胶过滤柱色谱的组合的纯化方法来实现。本发明通过基于该发现做出进一步研究而完成。
因此,本发明提供如下内容:
1.用于产生重组人α-Gal A的方法,其包括如下步骤:
(a)在无血清培养基中培养产生重组人α-Gal A的哺乳动物细胞,以让其在该培养基中分泌重组人α-Gal A,
(b)通过从在上述步骤(a)中获得的培养物去除细胞来收集培养物上清液,
(c)使在上述步骤(b)中收集的培养物上清液经过阴离子-交换柱色谱,以收集重组人α-Gal A-活性分级分离部分,
(d)使在上述步骤(c)中收集的该分级分离部分经过疏水柱色谱,以收集重组人α-Gal A-活性分级分离部分,
(e)使在上述步骤(d)中收集的该分级分离部分经过采用对磷酸基团具有亲和性的材料作为固相的柱色谱,以收集重组人α-Gal A-活性分级分离部分,
(f)使在上述步骤(e)中收集的该分级分离部分经过阳离子-交换柱色谱,以收集重组人α-Gal A-活性分级分离部分,
(g)使在上述步骤(f)中收集的该分级分离部分经过染料-亲和柱色谱,以收集重组人α-Gal A-活性分级分离部分,和

2.如上述(1)所述的方法,其中,阳离子-交换柱色谱中所用的阳离子交换器是弱阳离子交换器。
3.如上述(2)所述的方法,其中,所述弱阳离子交换器具有基于疏水相互作用和氢键形成的选择性。
4.如上述(2)或(3)所述的方法,其中,弱阳离子交换器具有苯基基团、酰胺键和羧基基团。
5.如上述(1)-(4)之一所述的方法,其中,所述染料-亲和柱色谱中所用的染料是蓝色三嗪染料。
6.如上述(1)-(5)之一所述的方法,其中,所述对磷酸基团具有亲和性的材料选自下组:羟基磷灰石和氟磷灰石。
7.如上述(6)所述的方法,其中,所述对磷酸基团具有亲和性的材料是羟基磷灰石。
8.如所述(1)-(7)之一所述的方法,其中,所述哺乳动物细胞是转染有表达载体的CHO细胞,所述表达载体经设计以在EF-1(α)启动子的调控下表达重组人α-Gal A。

发明效果
本发明允许从包含污染宿主细胞蛋白质的材料纯化rhα-Gal A。由此纯化的重组人α-Gal A适合作为药物用于法布瑞氏病的酶替代治疗(ERT)。在该治疗中,rhα-Gal A必须定期地给予患有法布瑞氏病的患者。因此,如果α-Gal A药物包含宿主细胞蛋白质,则采用该药物的ERT可能会具有诱导患者中针对宿主细胞蛋白质的严重抗原-抗体反应(即过敏性反应)的潜在风险。该风险可通过采用根据本发明纯化作为药物的rhα-Gal A而被最小化。此外,因为已允许以细胞的无血清培养作为起始来产生rhα-Gal A,本发明提供这样的rhα-Gal A,其不含任何血清源性的污染物,包括病原体例如病毒或朊病毒。因此,根据本发明获得的rhα-Gal A可作为安全药物给予人体,其基本不具有接触此类病原体的任何风险。此外,因为已允许以基本避免应用任何有机溶剂的方式纯化rhα-Gal A,本发明消除了rhα-Gal A变性的风险,否则,可能因与所用的有机溶剂接触而导致该风险。此外,本发明是环境有益的,因为在根据本发明的纯化方法进行之后剩下的废液不含有机溶剂,并且从经济角度考虑也是如此,因为本发明的方法不需要用于处理(在其它情况下将会包含在废液中的)有机溶剂的设备。
此外,本发明允许对在其寡糖链中有甘露糖-6-磷酸残基的rhα-Gal A的高度选择性纯化。为了在给予人体之后发挥其酶活,rhα-Gal A必需被相关细胞通过在其表面上表达的甘露糖-6-磷酸受体摄取。因此,本发明实现的高度选择性纯化将获得这样的rhα-Gal A产物,其作为药物具有显著增加的功效。

标准溶液如下制备:在稀释缓冲液(26.7mM柠檬酸盐-44.8mM磷酸盐缓冲液,pH4.6,包含0.1mg/mL BSA)中以0-200微摩尔/L的浓度溶解4-甲基伞形酮。底物溶液如下制备:在稀释缓冲液中以5mM的终浓度溶解4-甲基伞形基-α-D-半乳糖苷(SIGMA)。将10微升的各个标准品溶液或测试样品(用稀释缓冲液稀释)添加至96孔微滴定板(FluoroNunc板,Nunc)的各孔。将75微升的底物溶液添加至包含稀释的测试样品或任何标准品溶液的各孔,然后该板在不受影响的条件下37℃避光放置1小时。在该孵育之后,将200微升的停止缓冲液(0.2M甘氨酸-NaOH,pH 10.6)添加至各孔。然后各孔中溶液的荧光强度通过96孔板酶标仪以335nm波长的发射光和460nm波长的荧光检测。
标准曲线通过用标准品溶液测得的荧光强度绘点,并且在各绘制的数据点之间内插来产生。采用标准曲线,将各样品的荧光强度对应于释放的4-MUF的浓度。人α-Gal A的特定活性计算为单位/mg,其中一单位活性等于37℃每分钟产生的一微摩尔的4-MUF。参考公开的美国专利申请(公开号2004-0229250)来进行关于rhα-Gal A活性的上述检测。通过上述方法纯化的rhα-Gal A的特定活性显示为约50U/mg(48.3-53.7U/mg)。

此外,上述纯化的rhα-Gal A通过尺寸消除(Size-elimination)HPLC(SE-HPLC)进行分析。HPLC采用LC-20A系统,SPD-20AV UV/VIS检测器(Shimazu公司)进行。对于SE-HPLC分析,将包含2mg/mL的上述纯化的rhα-GalA的10微升的样品溶液施加至TSKgel G3000SWXL柱(7.8mm I.D.x30cm,TOSOH)上,该柱用25mM磷酸盐缓冲盐水(PBS)以0.5ml/分钟的流速平衡。通过监测215nm处的吸光度产生洗脱概况。
上述纯化的rhα-Gal A的SE-HPLC分析仅显示单一峰(图5)。结果显示上述获得的rhα-Gal A是高度纯化的且不含任何检测得到的污染物。该结果显示上述纯化的rhα-Gal A具有如此高的纯度以至于可以直接用作医药药物。

纯化步骤1-6中各自收集的rhα-Gal A-活性分级分离部分的汇集物中存在的污染宿主细胞蛋白质(HCP)通过ELISA以常规方式定量,并与该汇集物中所含的rhα-Gal A的量做比较。结果于表1中示为"HCP/rhα-Gal A(ppm)",其为HCP的与rhα-Gal A之质量比。如表1中所示,该比例,在最终的纯化步骤之后,低至20ppm,该水平足够低以允许因此纯化的rhα-Gal A用作通过注射重复给予人的药物。
在所述纯化方法的步骤中,第五,染料-亲和性色谱,最为有效地从被HCP污染的rhα-Gal A移除HCP。即,该步骤中,几乎97%的HCP被移除,并且HCP/rhα-Gal A比率从8.6x103ppm降至2.5x102ppm。结果显示染料-亲和性色谱是从rhα-Gal A制备物移除HCP的显著有效的方式。
