Description

一种重组人源化III型胶原蛋白、制备方法及应用
技术领域
本发明属于基因工程技术领域，具体涉及一种重组人源化III型胶原蛋白、制备方法及应用。
背景技术
胶原蛋白是人体内含量最丰富的一个蛋白质家族，是细胞外基质的主要组成成分。Ⅲ型胶原蛋白是一种成纤维胶原蛋白，它由3条α1(Ⅲ)肽链组成。III型胶原蛋白是血管、子宫和肠等中空器官的主要结构蛋白，它还经常与Ⅰ型胶原蛋白共生，广泛存在于皮肤、筋膜、肌腱等组织中。III型胶原蛋白为许多器官提供抗张强度和结构完整性，并参与调控细胞的黏附、增殖、迁移、分化等基本活动。III型胶原蛋白在伤口愈合、组织修复等过程中发挥关键作用，它被作为一种主要功能成分，被广泛应用于皮肤修复敷料中。
III型胶原蛋白因为与其他类型胶原蛋白共生，含量较低，因此，从动物组织提取III胶原蛋白存在难度大、纯度低、成本高等严峻问题。重组表达制备的胶原蛋白具有分子量单一、纯度高、无病毒传播隐患等优点，因此开始被用来替代动物胶原蛋白用于护肤品、敷料等领域。转基因植物、哺乳动物细胞等表达体系被用来制备重组胶原蛋白，但是它们存在培养条件严苛、生产周期长、成本高、表达量低等缺陷。大肠杆菌表达系统具有培养周期短、成本低等优点，在重组III型胶原蛋白的表达制备方面越来越受关注。
中国专利CN103122027A公开了一种以大肠杆菌为表达载体制备重组人源胶原蛋白的方法，该方法制备的重组胶原蛋白包括8或16次重复的III型胶原蛋白肽段和部分II型胶原蛋白肽段，并不是100％完全的III型胶原蛋白序列，同时该序列缺乏III型胶原蛋白与其他蛋白质相互作用的功能基序；中国专利CN110194795A制备包括8次重复的III型胶原蛋白肽段GERGGPGGPGPQGPPGKNGETGPQGPPGPT，该序列同样缺乏III型胶原蛋白与其他蛋白质相互作用的功能基序。中国专利CN111087463A和CN111087464A制备包括III型胶原蛋白N-端和C-端的肽段，但是该序列破坏了胶原蛋白特征性的Gly-X-Y重复序列；人体内的III型胶原蛋白要求100％严格遵守Gly-X-Y重复序列，即使单个破坏Gly-X-Y重复序列的突变也会导致疾病。
针对上述技术问题，本发明首先获得一种人III型胶原蛋白片段，所述生物活性高；其次，本发明提供了一种重组人源化III型胶原蛋白，所述重组人源化III型胶原蛋白包括人III型胶原蛋白片段，且与人III型胶原蛋白具有100％相同序列的肽段，同源性高；同时，所述重组人源化III型胶原蛋白100％严格遵守Gly-X-Y重复序列，不存在突变导致的疾病风险；而且，所述重组人源化III型胶原蛋白具有多个人III型胶原蛋白的重要功能位点，生物活性高；最后，本发明构建了一种重组人源化III型胶原蛋白的大肠杆菌表达体系，表达量高，易于纯化，制备的重组人源化III型胶原蛋白水溶性好，质量稳定，可广泛应用于护肤品、皮肤修复敷料、医学美容、保健食品等领域。

具体实施方式
以下具体结合实施例进一步描述本发明的技术方案，但本发明的保护范围不局限于以下所述。
本本发明提供了一种重组人源化III型胶原蛋白，所述重组人源化III型胶原蛋白包括至少一个氨基酸序列如SEQ ID NO.1所示的氨基酸单体；优选地，所述氨基酸单体为1-10个，优选地，所述重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.2-7等序列所示，由100％同源的人源III型胶原蛋白片段组成。本发明所述人源III型胶原蛋白片段来自人的天然氨基酸序列，生物相容性高，且每个单体序列中含有3个多个人III型胶原蛋白的重要功能位点，可供细胞表面受体识别，保证了胶原蛋白的良好生物学性能。
同时，依据本领域公知常识可以推论出：本申请所述重组人源化III型胶原蛋白中SEQ ID NO.1所示的氨基酸序列的重复次数越多，则序列中功能序列越多，可被受体识别的功能位点越多，则该序列的生物学活性越好。其中，当所述重组人源化III型胶原蛋白由1段SEQ ID NO.1所示的氨基酸序列组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ IDNO.2所示；当所述重组人源化III型胶原蛋白由2段SEQ ID NO.1所示的氨基酸序列重复组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.3所示；当所述重组人源化III型胶原蛋白由4段SEQ ID NO.1所示的氨基酸序列重复组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.4所示；当所述重组人源化III型胶原蛋白由6段SEQ ID NO.1所示的氨基酸序列重复组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.5所示；当所述重组人源化III型胶原蛋白由8段SEQ ID NO.1所示的氨基酸序列重复组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.6所示；当所述重组人源化III型胶原蛋白由10段SEQ ID NO.1所示的氨基酸序列重复组成时，重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.7所示；以下实施例以2段SEQ ID NO.1所示的氨基酸序列重复组成的重组人源化III型胶原蛋白(SEQ ID NO.3)为例，具体阐述蛋白制备、生物学评价和应用的内容，其他由不同SEQ ID NO.1所示的氨基酸序列重复组成的重组人源化III型胶原蛋白对应的结果可由此推论。
实施例1重组人源化III型胶原蛋白的制备过程
以SEQ ID NO.1所示的氨基酸为单体，确定单体个数n＝2的重组人源化III型胶原蛋白的氨基酸序列如SEQ ID NO.3所示。
构建重组人源化III型胶原蛋白的表达菌株：合成编码重组人源化III型胶原蛋白的核酸序列(SEQ ID NO.9所示)，构建导入上述核酸的质粒，通过DNA测序确认质粒成功合成；将质粒转化至大肠杆菌BL21-DE3菌株，获得重组人源化III型胶原蛋白表达菌株，将转化成功的菌株加入甘油后，保存于-80度冰箱。
重组人源化III型胶原蛋白的制备与纯化：取微量冻存的重组人源化III型胶原蛋白表达菌株，加入50ml LB培养基(含有抗生素)，在37℃培养过夜；将其转移到1L LB培养基(含有抗生素)，在37℃继续培养，待OD值达到0.5-2.0时，加入IPTG诱导,在25℃、20℃、15℃共培养8hrs-36hrs；离心收集菌体，加入缓冲溶液分散菌体，细胞破碎后，收集上清；通过盐析和离子交换层析纯化得到重组人源化III型胶原蛋白。

实施例2重组人源化III型胶原蛋白的生物学评价
1.细胞毒性实验
取生长至培养瓶底面积70％-80％的HeLa细胞，0.25％胰酶消化，用完全培养液制成细胞密度为1×105个/mL的细胞悬液。取100μL细胞悬液接种于96孔培养板中并置于37℃，5％CO2饱和湿度的培养箱中培养。细胞培养24hrs后，吸出完全培养液。在实验组中加入高糖DMEM培养基稀释的不同浓度的重组人源化III型胶原蛋白溶液(0.001-0.1mg/ml，每个浓度设置4个复孔)，对照组为DMEM培养基培养的细胞，空白组为不含细胞的DMEM培养基，继续于37℃、5％CO2饱和湿度的培养箱中培养24hrs。向各组加入CCK-8试剂10μL，细胞培养箱内孵育1-4hrs，使用酶联免疫检测仪在450nm波长下测各孔吸光度值(OD值)。根据各组的吸光度均值按照如下公式计算细胞存活率：
实验结果如图2所示，各浓度实验组的细胞活力都在95％以上，表明本发明制备的不同浓度的重组人源化III型胶原蛋白均无细胞毒性，安全性良好。
2.细胞增殖实验
取生长至培养皿面积70％-80％的人皮肤成纤维细胞(HFF-1)，0.25％胰酶消化,用完全培养液制成细胞密度为1×105个/mL的细胞悬液。取100μL细胞悬液接种于96孔培养板中并置于37℃，5％CO2饱和湿度的培养箱中培养。细胞培养24h后，吸出完全培养液。在实验组中加入高糖DMEM培养基稀释的0.1mg/ml的重组人源化III型胶原蛋白(设置4个复孔)，对照组为DMEM培养基培养的细胞，空白组为不含细胞的DMEM培养基，继续于37℃，5％CO2饱和湿度的培养箱中分别培养24h、48h、72h和96h。每隔一段时间，向各组加入CCK-8试剂10μL，细胞培养箱内孵育1-4h，使用酶联免疫检测仪在450nm波长下测各孔吸光度值(OD值)。根据各组的吸光度均值按照如下公式计算细胞的相对增殖率(RGR)：
实验结果如图3所示，与空白对照组(100％)相比，本发明制备的重组人源化III型胶原蛋白实验组在第2天、第4天的细胞相对增殖率均大于100％，且随着时间的增加而呈增加的趋势，表明本发明制备的重组人源化III型胶原蛋白可以促进人皮肤成纤维细胞的增殖。
3.细胞黏附实验
用PBS将重组人源化III型胶原蛋白稀释至0.1mg/mL，选用未TC处理的24孔细胞培养板，用0.1mg/mL重组人源化III型胶原蛋白处理孔板，每孔500μL样品，并于4℃冰箱中孵育24h。将生长至培养皿面积70％-80％的人成纤维细胞(HFF-1)用高糖DMEM培养基制成细胞密度为3×105个/mL的细胞悬液。将24孔板中的液体吸出，每孔加入500μL细胞悬液。5h后通过倒置显微镜观察细胞黏附效果。
实验结果如图4所示，在牛血清白蛋白(图4中A所示)中生长的成纤维细胞呈圆形、未铺展的状态，而在重组人源化III型胶原蛋白(图4中B所示)中生长的成纤维细胞大多呈铺展、黏附的状态，表明本发明实施例1制备的重组人源化III型胶原蛋白具有良好的细胞黏附性能。
4.细胞迁移实验
取生长至培养皿面积70％-80％的人皮肤成纤维细胞(HFF-1)，0.25％胰酶消化，用完全培养液制成细胞密度为5×105个/mL的细胞悬液。用马克笔比着直尺在孔板底部画3条横线，取500μL细胞悬液接种于6孔培养板中并置于37℃，5％CO2饱和湿度的培养箱中培养。细胞培养24h后，用10μl枪头比着直尺垂直对准孔板，向下轻推纵向形成划痕，吸出完全培养液，用PBS漂洗3次，去掉划掉的细胞。在实验组中加入高糖DMEM培养基稀释的0.5mg/ml的实施例1制备的重组人源化III型胶原蛋白溶液(设置3个复孔)；对照组为向细胞中加入等量未添加重组人源化III型胶原蛋白的高糖DMEM培养基。在37℃，5％CO2饱和湿度的培养箱中分别培养0h、24h，以横向和纵向划线的交点为核心，在40倍显微镜下拍照，获得9个部位的照片，每组合计27个数据。
结果如图5所示，在0h时(图5中A所示)中央划痕区无细胞，在重组人源化III型胶原蛋白溶液中培养24h(图5中B所示)，HFF-1迁移至中央划痕区，表明重组人源化III型胶原蛋白具有促进细胞迁移的能力。
