Description
技术领域
本发明涉及治疗肝癌方法的技术领域,特别是一种丹参酮IIA诱导癌细胞HepG2凋亡的实验方法。
背景技术
在过去几十年中,全球肝癌的发病率持续增加。仅2008–2010年间,全球因肝癌而死亡的病例从695900例增加到745500例,其中约一半发生在中国。近年来,研究表明肝癌的发生及发展涉及多个生物学信号传导途径。但由于肝癌发病机制复杂,寻求有效治疗药物一直是备受关注的热点问题。因此,关注多靶点药物的研究是药理学家研究肝癌治疗的关键。
中药以其多药理学作用机制,有效干预多种疾病而闻名,这为我们治疗病因复杂的肝癌提供了研究思路。丹参酮IIA是唇形科植物丹参干燥根的提取物,是一种心脏保护剂,肝脏保护剂。目前有文献报道丹参酮IIA主要是通过p53依赖性线粒体凋亡途径诱导肝癌细胞凋亡。然而,丹参酮IIA干预肝癌、诱导肝癌细胞凋亡的其它分子机制仍需进一步研究。
MicroRNA是一组通过控制mRNA降解和翻译来调节转录后基因表达的非编码单链RNA小分子。研究表明miRNA在生物学行为中起着关键作用。迄今为止,约一半的miRNA被估计位于癌症相关基因区域。此外,miRNA已经被证明是各种类型癌症中的癌基因和肿瘤抑制基因。在数百种miRNA中,miR30被认为是miRNA致癌信号通路的核心,特别是在实体瘤中p53分子是miR30的一个靶点。然而丹参酮IIA是否通过调节miR30而调控P53,目前尚不清楚。
生物信息学(Bioinformatics)是研究生物信息的采集、处理、存储、传播,分析和解释等各方面的学科,是生命科学的一个新兴领域。生物信息学的发展,在整合来自不同研究结果的基础上,帮助了人们快速分析建立药物(如丹参酮IIA)活性机制的复杂生物学网络。利用生物信息学相关工具提取和分析的信息可以有效地指示隐藏在生物数据库背后的基础信息,有助于揭示生物大分子间的相互作用。它虽然不能用来替代生物实验,但其操作方便、省时,可以用以快速筛选中药药物活性机制。

如图1所示,图1A:HepG2细胞的增殖情况(与对照组相比**P<0.01);图1B:HepG2细胞培养基中LDH水平检测(与对照组相比**P<0.01);图1:Hochest染色观察凋亡细胞的形态学变化;图1D:流式细胞术检测HepG2细胞凋亡情况;图1E:流式细胞术检测HepG2细胞周期停滞情况。可以得出以下的结果:
丹参酮IIA诱导HepG2细胞凋亡及细胞周期阻滞:
为研究丹参酮IIA对HepG2细胞的作用,我们检测细胞活性,并进一步分析细胞凋亡和细胞周期。从图1A可以看出,HepG2细胞的增殖以剂量依赖性方式在丹参酮IIA 40μM及以上降低。在80μM的丹参酮IIA作用下,细胞活力被抑制至接近53%。同样的,随着丹参酮IIA在培养基中浓度的升高其LDH水平也持续地升高(图1B)。丹参酮IIA还诱导Hep3B细胞中LDH的产生,在80μM时是对照组的1.6倍(图S1),表明其对肝癌细胞具有明显的的细胞毒性。
细胞凋亡和细胞周期阻滞是细胞生长抑制的两个主要途径。我们采用流式细胞术和荧光染色检测细胞凋亡。Hochest 33324是一种常用的DNA蓝色荧光染料,目前被广泛用于检测细胞活性。如图1C所示,丹参酮IIA处理组可观察到细胞形态学发生改变。在对照组中,细胞核呈椭圆型并被染成蓝色。而在加入丹参酮IIA后,细胞核皱缩,荧光强度变大,这表明细胞发生了凋亡。流式细胞仪显示40μM和80μM 处理组分别诱导9.2%和18.5%的HepG2细胞凋亡(图1D)。在丹参酮IIA作用下,细胞周期中G0 / G1的占比增大,并具有剂量效应关系(图1E)。在用40μM丹参酮IIA处理后,约25%的细胞在G1/G0周期停滞。当加药剂量达到80μM时,该比率增加至58%。这些结果均表明丹参酮IIA可以抑制HepG2细胞生长,包括细胞凋亡和细胞周期停滞。
如图2所示,图2A: miR30家族的转录热点图;图2B:HepG2细胞培养基中LDH水平检测;图2C:HepG2细胞Tp53的表达情况;(与对照组相比*P<0.05,**P<0.01;丹参酮IIA组与丹参酮IIA+ miR30b抑制剂组相比# P<0.05);其中miR30b-N: miR30b对照序列;miR30b-I:miR30b抑制序列。可以得出以下的结果:
丹参酮IIA对miR-30b-p53的调节
已知p53蛋白与线粒体途径介导的细胞凋亡和G0周期停滞相关。我们检测了丹参酮IIA对p53信号的传导。其中丹参酮IIA在大于等于40μM浓度时显著诱导Tp53基因。最大诱导约为对照组的两倍。miR30家族是p53的上游。如热点图(图2)和表1所示,丹参酮IIA没有显著改变miR30c和miR30d的表达,对两者转录水平的影响仅较对照组降低了10%。而丹参酮IIA对miR30b具有显著的调控作用。当用40μM和80μM丹参酮IIA处理时,miR30b的水平分别降低至对照组的80%和70%。同时,结合上述结果,我们运用miR30b抑制剂,对细胞毒性及Tp53的表达进行了检测。研究结果表明,丹参酮对HepG2细胞LDH的诱导被miR30b抑制剂所抑制。且丹参酮组Tp53基因的显著上调也受到抑制。因此,我们推测miR30b-p53在丹参酮IIA介导的细胞凋亡中起关键作用。
表1 miR30家族受丹参酮IIA的系列浓度下调
注:与对照组相比* P<0.05,** P<0.01;N表示与对照组无显著差异。
如图3所示,图3A:丹参酮IIA调节凋亡相关基因的表达(与对照组相比*P<0.05,**P<0.01);图3B:丹参酮IIA调节凋亡相关蛋白质水平;图3C:丹参酮IIA调节细胞周期相关蛋白质水平。可以得出以下的结果:
丹参酮IIA对凋亡相关基因和蛋白的调节
丹参酮IIA显著影响了Bcl2家族,包括Bcl2(抗细胞凋亡)和Bax(促凋亡)的转录,Bax /Bcl2的比例从在40μM组的1.6倍增加到在80μM组的4.3倍(图3A)。 Western Blot数据(图3B)结果与PCR结果一致,在80μM组中Bcl2的强度降低了1.4倍。随着药物剂量的增加,Bax的蛋白质水平从对照组的1.3倍增加到2.0倍。80μM处理组p53的基因和蛋白质水平都增加到对照组的1.9倍。我们在Hep3B中也观察到同样的作用(图3A)。Caspase 3是凋亡执行分子,在40μM和80μM的丹参酮IIA作用下,Caspase3分别上调了2.5和2.7倍。p21蛋白作为G1和S期细胞周期进程的调节蛋白,其表达受p53控制,并参与p53依赖性的G1期阻滞。当用不同浓度的丹参酮IIA处理时,p21的转录从1.6倍增加到2.3倍(图3A)。CyclinD1是细胞周期蛋白依赖性激酶(CDK),它是细胞从G1期到S期的重要调控蛋白。在80μM 组中,CCND1基因的编码CyclinD1下降至对照组的0.43倍。此外,40μM和80μM的丹参酮显著降低了CDK6的基因表达水平,分别降低至对照组0.82和0.49倍(图3A)。图3C显示80μM处理组的CyclinD1的蛋白表达水平相比于对照组降低了20%。另外,CDK6的蛋白质水平也受到了明显的抑制,在80μM作用下,降低了30%。
本实验方法还可以得出以下的结果:
PTPN11 / SHP2可能为丹参酮IIA抗癌药理学机制的关键分子。
通过生物信息学筛选丹参酮IIA的潜在靶点分子。结合文献检索,我们对丹参酮IIA调控的61个不同基因进行GO积累分析以揭示这些基因的可能的生物学功能。结果显示这些基因Go Item主要集中于细胞生长,细胞周期,细胞分化,抗/凋亡和线粒体等相关的GoTerm。此外,我们使用更先进的GeneCodis进行信号通路注释,共得到49个KEGG信号通路。
丹参酮IIA对PTPN11 / SHP2的调控
根据生物信息学所得结果,我们检测了丹参酮IIA对HepG2细胞中PTPN11和PTPN6 mRNA水平。丹参酮IIA对PTPN6没有显著影响。但在80μM时,它可引起PTPN11的上调。在Hep3B中,80μM丹参酮IIA也能诱导PTPN11,其最大诱导达到对照组的1.2倍。同样的,由PTPN11编码的SHP2蛋白水平在丹参酮IIA作用后也有所上升,80μM处理组是对照组的1.7倍。该结果表明丹参酮IIA的抗肝癌作用可能通过PTPN11 / SHP2信号通路。
转录因子筛选PTPN11和动力学结合
在本节中,我们试图寻找miR30b-p53与PTPN11这两种主要信号途径之间是否存在联系。考虑到p53是一个重要的转录因子,我们利用LASAGNA进行了PTPN家族转录因子的搜索。结果表明,p53是PTPN的潜在转录因子。搜索结果中所包括的特定序列,位置,得分,p值和E值的结合参数列于表2中。LASAGNA-搜索结果显示,p53和PTPN 6(PTPN6 NM_080549,NM_080548)的最大结合评分为65.01和63.9(P<0.004)。p53和PTPN11(PTPN NM_002834)的结合评分为67.14(P<0.002)(表2)。
为了进一步确认p53蛋白质与PTPN的相互作用,我们进行了基于SPR成像的分子互作测定(由于丹参酮IIA对HepG2细胞中PTPN6的诱导表达不明显,此部分研究结果仅在PTPN11中进行)。我们应用3D技术来制造包含上述PTPN11的28个序列的小分子微阵列。阳性对照的RU值达到160,阴性对照的信号几乎与背景重叠,表明该分析方法的可靠性。SPRi系统筛选可以得到了8个能与p53蛋白相互作用的PTPN11 DNA序列。动力学结合信号随注入的p53浓度的上升而增加。结合参数RU在注射300nM p53 200分钟后达到峰值。这表明p53和PTPN11之间的显着亲和力。根据上述研究结果,我们进一步利用miR30b抑制剂对丹参酮IIA对 PTPN11的调控进行了研究。结果表明,miR30b抑制剂通过对p53的抑制作用,间接抑制了丹参酮对PTPN11的诱导作用。因此,本研究推测丹参酮IIA对HepG2凋亡的诱导是通过miR30b-p53-PTPN11途径。
表2 从LASAGNA-搜索提取的p53和PTPN之间的结合参数和序列
本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
