阿尔茨海默病(Alzheimer′s disease,AD)是一种神经退行疾病,近年来其发病率不

断增高。现有许多证据支持淀粉样蛋白(amyloid beta,Aβ)的沉积是AD主要致病

机制之一[1]。因此,减少Aβ沉积成为治疗AD的一条重要途径。β位点裂解酶-

1(BACE1)是体内主要的β-分泌酶,是裂解淀粉样前体蛋白(APP)产生Aβ的限速

酶。Aβ具有神经毒性,可引起神经突触功能障碍、神经元丢失,进而导致认知功

能受损[2]。研究表明,在小鼠脑内注射BACE1的小干扰RNA可减轻APP转基因

小鼠的Aβ沉积和提高认知功能[3-6],这说明抑制BACE1表达会改善Aβ相关的

认知功能障碍,因此β-分泌酶BACE1被作为开发AD药物的潜在靶点。

目前,BACE1基因单核苷酸多态性与AD发病是否相互作用尚未定论[7-8],而针

对BACE1分子的靶向治疗有望为治疗AD提供新思路,但对于BACE1分子的上

游调控机制仍不清楚。为此本试验通过克隆人BACE1基因核心启动子区,构建荧

光素酶报告系统并筛选其稳定表达细胞株,为进一步研究BACE1基因转录调控、

多态性分析及其高通量药物筛选提供有力工具。

1.2.3 BACE1基因启动子荧光素酶报告载体的构建 PCR产物和pGL4.21载体经

NheI和XhoI双酶切后,在T4 DNA连接酶作用下16 ℃连接过夜并转化入

DH5α感受态细胞,挑取2个氨苄青霉素筛选的阳性克隆。再经NheI和XhoI双

酶切鉴定后送上海英骏公司测序,测序正确的命名为pGL4.21-BACE1,提取质粒

后-20 ℃保存备用。

1.2.4 细胞培养及稳定表达株的筛选 HEK293细胞培养于含有10%胎牛血清,100

U/mL青霉素和 100 μg/mL链霉素的 DMEM培养基,置于37 ℃、5%CO2的培

养箱中培养。将汇合度约80%的HEK293细胞以4×105接种6孔板,待细胞贴

壁生长至约70%~80%汇合度时进行转染。用Opti-MEM培养基分别稀释载体

pGL4.21-BACE1(每孔5 μg)和脂质体(每孔5 μL)(单独转染pGL4.21作为阴性对

照组),室温孵育5 min,载体和脂质体混合后室温孵育20 min,加入HEK293

细胞中,37 ℃、5%CO2的培养箱中培养。转染后48 h采用1 μg/mL浓度的嘌

呤霉素筛选,筛选第14天时采用96孔板有限稀释法克隆化,待单细胞长满后转

至24孔板继续培养,然后依次转至12孔板、6孔板及10 cm培养皿继续扩大培

养(此过程2~3个月)。得到来自6株单克隆扩大培养的稳定表达细胞株,用化学

发光仪检测其转录活性。选取荧光强度最高的进行后续试验并命名为

HEK293/pGL4.21-BACE1(阴性对照组命名为HEK293/pGL4.21)。

1.2.5 荧光素酶活性测定 荧光素酶活性测定按照荧光素酶活性检测试剂盒说明书进

行操作。简单来说,将HEK293/pGL4.21-BACE1和HEK293/pGL4.21(阴性对照

组)细胞以2×104接种96孔板(各3个重复孔),培养24 h后每孔加与培养基等体

积的Luciferase Reagent,轻轻混匀。室温裂解10 min后在化学发光仪Glomax

96(Promega)中测量萤火虫荧光素酶活性。

1.3 统计学处理 采用SAS14.0的统计软件进行统计分析,计量资料用表示,采用

Excel student′s t检验分析,检验水准α=0.05,以P<0.05为差异有统计学意义。

2.1 BACE1基因启动子扩增产物的鉴定 提取HEK293细胞基因组DNA,以其为

模板进行PCR扩增BACE1基因上游长度758 bp的核心启动子(-691~+67),

PCR产物经1%琼脂糖电泳可见大小约758 bp的条带,与目的片段大小相符,见

图1。

2.2 荧光素酶报告载体pGL4.21-BACE1的构建与鉴定 758 bp的PCR产物与携带

萤火虫荧光素酶基因的pGL4.21分别以NheI和XhoI双酶切,连接并转化DH5α

后挑取2个阳性克隆子。经NheI和XhoI双酶切后可见大小约5 532

bp(pGL4.21)与758 bp(BACE1启动子)的2个片段出现(图2A)。测序验证也正确,

这说明本研究成功构建携带BACE1启动子的荧光素酶报告载体,见图2B。

2.3 构建稳定表达BACE1启动子的细胞系 pGL4.21-BACE1和阴性对照pGL4.21

转染HEK293细胞(6孔板)后48 h,培养基中加入嘌呤霉素进行稳定筛选。培养

第14天时采用有限稀释法克隆化,最后筛选得到6株单克隆稳定表达细胞株

HEK293/pGL4.21-BACE1(克隆子1~6)。

2.4 稳定表达细胞株具有转录活性 本研究对筛选到的6株稳定表达细胞株进行荧

光素酶活性检测(把阴性对照组HEK293/pGL4.21的荧光值看作1)。结果表明,

克隆子1~6均具有较强的荧光活性,其荧光值分别为对照组(HEK293/pGL4.21)

的(134.7±22.3)、(634.0±13.9)、(437.6±6.1)、(805.5±5.5)、(492.8±59.1)、(1

021.1±46.6)倍(P=0.001)。其中,6号克隆子荧光活性最强,作为后续试验使用。

BACE1是人体内唯一的β分泌酶,它能剪切APP生成Aβ,且在AD患者脑中,

Aβ是淀粉样炎症斑的主要组成成分,Aβ沉积在AD的发生、发展中起着关键作

用。抑制BACE1活性以降低Aβ生成成为治疗AD的靶点。目前对AD治疗的研

究均致力于开发β-和γ-分泌酶抑制剂,以抑制Aβ的产生[10-13],但是APP还

可以被α-和γ-分泌酶裂解产生可溶性且具有神经营养和神经保护作用的sAPPα

片段。所以非特异性地抑制γ-分泌酶会导致生理功能紊乱[14]。有报道称在AD

发病过程中,Aβ随着BACE1的上调而增多,并与AD发病呈正相关[15];用

BACE1 siRNA处理神经干细胞后Aβ产生明显减少[6]。BACE1过表达或活性增

强可能导致Aβ过度产生,最终诱导认知功能损伤。因此,针对BACE1的靶向治

疗可能成为治疗AD的一种新途径[10-12]。因此,构建携带BACE1基因的荧光

素酶报告载体来研究BACE1基因的调控和功能具有重要意义。

利用荧光素酶报告载体研究启动子对下游基因的调控,可以避免下游基因表达产物

对启动子的干扰,能较好地反映外在因素对调控序列的影响。近年来,利用荧光素

酶报告基因载体的药物筛选方法得到广泛应用。本试验通过克隆人BACE1基因核

心启动子,构建萤火虫荧光素酶报告载体pGL4.21-BACE1,并成功筛选到6株稳

定表达该启动子的HEK293细胞株。本研究构建的HEK293/pGL4.21-BACE1细

胞株具有较强的转录活性,虽然比瞬时转染时的转录活性低1~2个数量级,但是

稳定表达更利于药物的高通量筛选,减少了组间差异。

综上所述,本试验成功构建BACE1启动子驱动的荧光素酶报告载体,并筛选到了

稳定表达细胞株,将为高通量药物筛选及进一步研究BACE1基因的转录调控提供

重要的细胞学研究手段。

第14天时采用有限稀释法克隆化,最后筛选得到6株单克隆稳定表达细胞株

HEK293/pGL4.21-BACE1(克隆子1~6)。

2.4 稳定表达细胞株具有转录活性 本研究对筛选到的6株稳定表达细胞株进行荧

光素酶活性检测(把阴性对照组HEK293/pGL4.21的荧光值看作1)。结果表明,

克隆子1~6均具有较强的荧光活性,其荧光值分别为对照组(HEK293/pGL4.21)

的(134.7±22.3)、(634.0±13.9)、(437.6±6.1)、(805.5±5.5)、(492.8±59.1)、(1

021.1±46.6)倍(P=0.001)。其中,6号克隆子荧光活性最强,作为后续试验使用。

BACE1是人体内唯一的β分泌酶,它能剪切APP生成Aβ,且在AD患者脑中,

Aβ是淀粉样炎症斑的主要组成成分,Aβ沉积在AD的发生、发展中起着关键作

用。抑制BACE1活性以降低Aβ生成成为治疗AD的靶点。目前对AD治疗的研

究均致力于开发β-和γ-分泌酶抑制剂,以抑制Aβ的产生[10-13],但是APP还

可以被α-和γ-分泌酶裂解产生可溶性且具有神经营养和神经保护作用的sAPPα

片段。所以非特异性地抑制γ-分泌酶会导致生理功能紊乱[14]。有报道称在AD

发病过程中,Aβ随着BACE1的上调而增多,并与AD发病呈正相关[15];用

BACE1 siRNA处理神经干细胞后Aβ产生明显减少[6]。BACE1过表达或活性增

强可能导致Aβ过度产生,最终诱导认知功能损伤。因此,针对BACE1的靶向治

疗可能成为治疗AD的一种新途径[10-12]。因此,构建携带BACE1基因的荧光

素酶报告载体来研究BACE1基因的调控和功能具有重要意义。

利用荧光素酶报告载体研究启动子对下游基因的调控,可以避免下游基因表达产物

对启动子的干扰,能较好地反映外在因素对调控序列的影响。近年来,利用荧光素

酶报告基因载体的药物筛选方法得到广泛应用。本试验通过克隆人BACE1基因核

心启动子,构建萤火虫荧光素酶报告载体pGL4.21-BACE1,并成功筛选到6株稳

定表达该启动子的HEK293细胞株。本研究构建的HEK293/pGL4.21-BACE1细

胞株具有较强的转录活性,虽然比瞬时转染时的转录活性低1~2个数量级,但是

稳定表达更利于药物的高通量筛选,减少了组间差异。

综上所述,本试验成功构建BACE1启动子驱动的荧光素酶报告载体,并筛选到了

稳定表达细胞株,将为高通量药物筛选及进一步研究BACE1基因的转录调控提供

重要的细胞学研究手段。
