Abstract
本发明提供了一种可诱导肿瘤细胞程序性坏死的蛋白及其制备方法和应用。蛋白的制备方法：将黍子籽粒或黍糠粉碎，加入蛋白提取液低温提取，随后加入硫酸铵沉淀蛋白，再经过脱盐，阳离子交换层析和凝胶层析等步骤获得纯的蛋白。经实验这种蛋白可以诱导结直肠癌、肝癌等多种肿瘤细胞发生程序性坏死，其可以在制备抗肿瘤药物和保健食品中应用。
Description
技术领域
本发明涉及植物功能蛋白制备和应用，具体属于一种来源于黍子籽粒或黍糠的可以诱导肿瘤细胞程序性坏死的蛋白及其制备方法，以及该蛋白在制备抗肿瘤药物中的应用。
背景技术
黍子(Panicum miliaceum L.)属禾本科黍属，一年生草本植物，主要生长在北方。籽实也叫黍子，糜子，淡黄色，去皮后俗称黄米，常用于制作年糕，酿酒的原料，是重要的粮食作物之一。
黍子种子中含有17种氨基酸，含量较高，特别是必需氨基酸含量为4.76mg/100g，含量明显高于小麦，且与标准食谱相近，易于人体吸收，可以作为人体营养的补充食物。黍子籽粒中的钙、镁、磷及微量元素铁、铜、锌含量是水稻的3.4倍、小麦的2.3倍、玉米的1.05倍，并且含有一定量的硒。这些微量元素对于活化人体免疫性和正常的生理功能，抗衰老、预防心血管病等方面有着重要的作用。此外，黍子具有一定的药用价值，是我国传统的中草药之一。黍子性味甘、平、微寒、无毒。据《名医别录》记载：稷米“入脾、胃经”，功能“和中益气、凉血解暑”。煮熟和研末食，主治气虚乏力、中暑、头晕、口渴等症。黍米“入脾、胃、大肠、肺经”，功能“补中益气、健脾益肺、除热愈疮”。主治脾胃虚弱、肺虚咳嗽、呃逆烦渴、泄泻、胃痛、小儿鹅口疮、烫伤等症。
目前国内外关于黍子中活性物质的研究还较少，仅仅集中在其化学成分(植物多酚)和营养价值方面。黍糠是黍子加工过程中脱壳而得到的皮壳，也含有多种生物活性成分，是一种廉价而潜在的资源。本发明发现的来源于黍子，可诱导肿瘤细胞程序性坏死的蛋白具有较高的抗肿瘤活性，可在制备抗肿瘤药物中应用。另外，这一发现将为进一步研究开发黍子高附加值产品以及黍子资源的综合利用提供思路和依据，从而有利于推动黍子产业的规模化和持续化发展，带动我国半干旱、高海拔地区的经济发展。
发明内容
本发明的目的在于提供一种可诱导肿瘤细胞程序性坏死的蛋白及其制备方法，以及将该蛋白在制备抗肿瘤药物中得到应用。
本发明提供的一种可诱导肿瘤细胞程序性坏死的蛋白，来源于黍子(PanicummiliaceumL.)籽粒或黍糠，其分子量为37kD，氨基酸序列为SEQ ID No.1。
本发明提供的一种可诱导肿瘤细胞程序性坏死的蛋白，可以通过如下步骤的方法制得：
第一步：取干燥的黍子籽粒或黍糠，进一步粉碎后，然后按每克粉末加入10-15mL预冷的酸性蛋白提取液，4℃下搅拌4-8小时，8000-12000rpm离心10-20分钟除去沉淀，收集上清，得到蛋白粗提液；所述的酸性蛋白提取液为20mmol/L醋酸铵缓冲液，pH4.5；
第二步：在蛋白粗提液中加入硫酸铵，至60％-80％的饱和度，在4℃搅拌3-5小时；8000-12000rpm离心20-30分钟，收集沉淀；
第三步：用少量pH7.0的磷酸盐缓冲液溶解沉淀，上样于脱盐柱，除去硫酸铵，收集蛋白峰得到蛋白粗品；
第四步：将蛋白粗品上样于HiTrapTM SP弱阳离子交换进行分离纯化，收集洗脱峰，将收集的洗脱峰蛋白上样于凝胶层析柱，收集活性蛋白峰，真空冷冻干燥，得到可以诱导肿瘤细胞程序性坏死的蛋白。采用SDS-PAGE分析，该蛋白的分子量约为37kD。经胰蛋白酶和胰凝乳蛋白酶水解及肽质量指纹图谱鉴定，并结合Edman降解法测定其N端序列，确定氨基酸序列为SEQ ID No.1。
本发明提供的肿瘤细胞程序性坏死蛋白是一种热稳定性较好，经紫外-可见分光光度计检测，该蛋白在280nm和400nm处有吸收峰。
经体外抗肿瘤活性检测显示，该蛋白通过诱导多种肿瘤细胞发生程序性坏死，可以显著地抑制肿瘤细胞增殖。当用终浓度为100ug/mL的该蛋白处理结肠癌细胞HT29细胞24小时，对该细胞的增殖抑制率达到60％以上，而当作用时间为48小时时，增殖抑制率达到90％以上。
本发明获得的蛋白可以通过诱导肿瘤细胞坏死发挥抗增殖作用，因为程序性细胞坏死与经典的细胞凋亡在信号通路上存在较大的不同，当细胞凋亡通路被抑制时，在胞外信号刺激下可以诱导细胞发生程序性坏死。因此该蛋白对一些对常规药物表现出抗性的细胞已具有显著的增殖抑制作用。该蛋白可以在制备抗肿瘤药物中应用，也可以在保健食品的制备中应用。
本发明首次从黍子中分离纯化出一种可以诱导肿瘤细胞发生程序性坏死的蛋白，对多种肿瘤细胞具有显著的增殖抑制作用。这一蛋白的发现为糜子高附加值产品以及糜子资源的综合利用提供思路和依据，具有巨大的经济价值，同时也为抗肿瘤药物及保健食品的开发提供技术支持。

具体实施方式
实施例1：黍子籽粒型可诱导肿瘤细胞程序性坏死的蛋白的制备
将烘干的黍子籽粒，进行粉碎后，收集粉末；称取100g粉末，加入1000mL pH 4.5的20mM的醋酸盐缓冲液，4℃提取6小时，8000rpm离心20分钟除去沉淀，然后加入硫酸铵，至80％的饱和度；在4℃搅拌4小时，使蛋白充分沉淀，8000rpm离心30min，收集沉淀，用30mLpH7.0的PBS缓冲液将沉淀重新溶解；将溶解的沉淀上样于HiPrepTM26/10脱盐柱，除去硫酸铵，收集蛋白峰得到蛋白粗提物；将粗提物上样于HiTrapTM SP弱阳离子交换进行分离纯化，收集氯化钠洗脱峰，将收集的洗脱峰蛋白样品再次上样于HiPrepTM 26/10脱盐柱，收集蛋白峰，真空冷冻干燥，得到黍子籽粒中可诱导肿瘤细胞程序性坏死蛋白。采用Folin-酚法测定蛋白浓度，经计算采用该方法制得9.1mg可诱导肿瘤细胞程序性坏死的蛋白，经SDS-PAGE分析,分子量大小为37kD。
实施例2：黍糠型可诱导肿瘤细胞程序性坏死的蛋白的制备
将黍子加工过程中的副产物黍糠，进行进一步粉碎后，收集粉末；称取100g粉末，加入1000mL pH 4.0的20mM的醋酸盐缓冲液，4℃提取4小时，8000rpm离心20min除去沉淀，上清用纱布过滤，然后加入硫酸铵，至80％的饱和度；在4℃搅拌4小时，使蛋白充分沉淀，8000rpm离心30min，收集沉淀，用30mL pH7.0的PBS缓冲液将沉淀重新溶解；将溶解的沉淀上样于HiPrepTM 26/10脱盐柱，除去硫酸铵，收集蛋白峰得到蛋白粗提物；将粗提物上样于HiTrapTM SP弱阳离子交换柱进行分离纯化，收集洗脱峰，将收集的洗脱峰蛋白样品再次上样于HiPrepTM26/10脱盐柱，收集蛋白峰，真空冷冻干燥，得到黍糠中可诱导肿瘤细胞程序性坏死的蛋白。采用Folin-酚法测定蛋白浓度，经计算采用该方法制得16.5mg可诱导肿瘤细胞程序性坏死的蛋白。经SDS-PAGE分析,分子量大小为37kD(见图1)。经紫外-可见分光光度计检测，该蛋白在280nm和400nm两处有特征吸收峰(见图2)。
实施例3可诱导肿瘤细胞程序性坏死的蛋白氨基酸序列的测定
经SDS-PAGE分离后，切下含有实施例2制备的蛋白的条带，经胰蛋白酶和胰凝乳蛋白酶水解后，进行肽质量指纹图谱鉴定。经胰蛋白酶水解后的样品然后进行MALDI-TOF/TOF-MS检测，测得肽质量指纹谱，在数据库中查询识别的方式鉴定实施例2制备的蛋白。经过BLAST分析，找出与鉴定的蛋白同源性较高的序列。经胰凝乳蛋白酶水解后的样品测得肽质量指纹图谱，在数据库中进行搜索比对，找出与数据库中相符的肽段。将两种酶水解后得到的肽段进行拼接，得到实施例2制备的蛋白的主体序列。将实施例2制备的蛋白应用Edman降解法测定N端20个氨基酸序列。该N端序列和肽质量指纹图谱得到的序列进行拼接，得到实施例2制备的蛋白完整的氨基酸序列，该序列如SEQ ID No.1所示。
实施例4：可诱导肿瘤细胞程序性坏死的蛋白对肿瘤细胞生长抑制实验(MTT法)
应用MTT法，检测实施例2制备的蛋白对肿瘤细胞株Hep G2，HT29，SW480，HCT116等的生长抑制作用。取对数生长期的细胞，以1-5×103个/孔传入96孔培养板，37℃含5％的CO2细胞培养箱中孵育24小时后，分别加入可诱导肿瘤细胞程序性坏死的蛋白，使其终浓度分别为25μg/mL,50μg/mL,75μg/mL,100μg/mL,每组浓度设5个复孔，并用等体积的pH 7.0的20mM/L PBS缓冲液作为对照，孵育48h后，每孔加入20μL MTT试剂(5mg/mL)，继续孵育4小时后，终止培养，弃去孔内培养上清，每孔加入150μL DMSO,振荡10分钟，使结晶物充分溶解，在酶标仪上490nm波长处测定其光吸收值。本发明所得黍糠肿瘤细胞程序性坏死蛋白对HepG2,SW480，HCT116和HT29具有显著的增殖抑制作用(见图3)。
实施例5：可诱导肿瘤细胞程序性坏死的蛋白对肿瘤细胞生长抑制实验(ATP法)
细胞内ATP快速降低是细胞发生坏死的一个显著特征，通过测定细胞内ATP含量，检测实施例2制备的蛋白对肿瘤细胞株Hep G2，HT29，SW480，HCT116等的生长抑制作用。取对数生长期的细胞，以1-5×103个/孔转入不透光的96孔板，用25μg/mL,50μg/mL,75μg/mL,100μg/mL可诱导肿瘤细胞程序性坏死蛋白，分别处理细胞48h，弃去培养液，加入100μLDMEM培养基室温平衡30min,添加100μL Cell Titer-Glo试剂，摇床混合2min,诱导细胞裂解,室温孵育10min，稳定发光信号,酶标仪检测发光信号。结果显示，本发明所得可诱导肿瘤细胞程序性坏死蛋白对Hep G2，SW480，HCT116和DLD1细胞中ATP的降低有非常显著的效果，具有显著的增殖抑制作用(见图3)。
实施例6：凋亡抑制剂z-VAD和坏死抑制剂Nec-1对本发明蛋白诱导HCT116细胞死亡的影响
当细胞内Caspase酶活性被抑制，细胞的活性进一步减弱，而细胞程序性坏死抑制剂necrostatin-1(Nec-1)可以特异性抑制细胞坏死，使细胞活力恢复。取对数生长期的细胞，以1-5×103个/孔转入96孔培养板，37℃含5％的CO2细胞培养箱中孵育24小时后，分别加入终浓度为50μg/mL可诱导肿瘤细胞程序性坏死蛋白，同时加入不同浓度的抑制剂z-VAD和Nec-1，每组浓度设5个复孔，并用等体积的pH 7.0的20mM/L PBS缓冲液作为对照，孵育48h后，每孔加入20μL MTT试剂(5mg/mL)，继续孵育4小时后，终止培养，弃去孔内培养上清，每孔加入150μL DMSO,振荡10分钟，使结晶物充分溶解，在酶标仪上490nm波长处测定其光吸收值。结果显示，当Caspase抑制剂z-VAD与可诱导肿瘤细胞程序性坏死蛋白共同作用时，显著加强了可诱导肿瘤细胞程序性坏死蛋白诱导的细胞死亡，而坏死抑制剂Nec-1显著减弱了可诱导肿瘤细胞程序性坏死蛋白诱导的细胞死亡(见图4)。结果表明,可诱导肿瘤细胞程序性坏死蛋白诱导的细胞死亡是程序性坏死，而不是细胞凋亡。
