Description

血清中用于肝脏损伤疾病早期诊断的分子标记物
技术领域
本发明涉及生物医学技术领域,具体涉及一种血清中用于肝脏损伤疾病早期诊断的分子标记物。
背景技术
各种原因导致的肝病是目前影响我国人民健康的主要因素之一,包括病毒性肝炎、脂肪肝、自身免疫性肝炎、药物性肝炎和遗传性肝病等。近年来,随着生活水平的提高,人们的酒精和食物(糖)摄入量呈升高趋势,酒精性肝病/脂肪肝已成为不可忽视的公共健康问题。初期通常表现为脂肪肝,进而可发展成酒精性肝炎、肝纤维化和肝硬化。随着近年来各种先进医疗诊断技术的发展和疾病认识的提高,使得过去难于诊断的自身免疫性肝炎和遗传性肝病等临床上也不再罕见。各种病毒性肝炎、脂肪肝、自身免疫性肝炎和遗传性肝病等愈来愈成为严重影响人民健康的因素,这些肝病终末期可导致肝硬化或肝癌。虽然近年来针对这些肝病的发病机理和药物研究等有了巨大进步,病毒性肝炎的抗病毒治疗药物有了突破性的发展,但是对这些肝病的发生发展和再生修复的机制仍然尚不完全清楚,判断肝病病情发展的生物标志物严重缺乏,成为临床判断肝病严重程度的难题之一。目前临床常用的血清肝功能检测标志物或方法包括:肝功能检测:谷丙转氨酶(alanineaminotransferase,ALT),谷草转氨酶(aspertate Aminotransferase,AST),碱性磷酸酶(alkaline phosphatase,ALP),谷氨酰转肽酶(glutamyl transpeptidase,GGT),总蛋白(total protein,TP),白蛋白(albumin,Alb);球蛋白(glubulin,G);A/G:白球蛋白比例(ALB/globulin ratio),总胆红素(total bilirubin,TBIL),间接胆红素(indirectbilirubin,IB),直接胆红素(direct bilirubin,DBIL),甲胎蛋白(alpha fetalprotein,AFP),甘胆酸(cholyglycine,CG),铁蛋白(serum ferritin,SF),前白蛋白(prealbumin,PA),转铁蛋白(transferrin,TF),总胆汁酸(total bile acid,TBA)。肝纤六项:透明质酸(hyaluronic acid,HA),层粘连蛋白(laminin,LN),IV型胶原(collagen Type IV,IV-C),Ⅲ型前胶原N端肽(type precollagenⅢN peptide,PⅢNP),甘胆酸、纤维连接蛋白(fibronectin,FN);高尔基体蛋白73(golgi protein73),异常凝血酶原(protein inducedby vitamin K absence or antagonist-II,PIVKA-II)等。

从第三军医大学西南医院感染病科门诊和住院部收集的患者血清,住院患者中采集了313名慢性乙型肝炎(chronic hepatitis B,CHB)患者、153名其他肝病患者和33名健康对照者的血清,健康对照者的血清收集自健康管理中心,使用了ELISA方法对血清中的SIX1蛋白用ELISA方法进行了检测。对上述患者血清进行ELISA检测,包括以下试验步骤:
将含有包被抗体的96孔板放置在4℃过夜,第二天开始实验前去除上清液,每个适当的孔中加入适当稀释的标准品SIX1/EYA1蛋白或样品50μl,然后加入辣根过氧化物酶(Horseradish Peroxidase,HRP)标记的检测抗体100μl并在37℃,60分钟。
然后对96孔板进行4次清洗,然后分别加入底物50μl TMB显色液(3,3',5,5'-四甲基联苯胺),在37℃放置15分钟,避光。
最后每个孔中加入50μl 1M盐酸终止液,在15分钟内用酶标仪(Multiskan,ThermoScientific,Waltham,MA,美国)测量每个孔在450nm的光密度(optical density,O.D),然后根据标准曲线计算出每个样本的蛋白浓度,检测结果如表1至表3所示。

表3.动态观察35个慢乙肝患者血清中SIX1和EYA1的变化
Figure BDA0002911843480000081
血清检测结果如表1至表3所示,结果显示313例慢性乙型肝炎患者血清SIX1和EYA1水平分别为7.24±0.11ng/ml和25.21±0.51ng/ml,显著高于33例健康对照者(2.84±0.15ng/ml和13.11±1.01ng/ml;P<0.05)。肝纤维化、脂肪肝、酒精性肝病、暴发性肝衰竭、自身免疫性肝病和丙型肝炎患者血清SIX1也比健康对照组血清SIX1显著升高(P<0.05)。动态观察35例慢性乙型肝炎患者中SIX1和EYA1血清水平在34至193天的间隔内增加,而丙氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST)水平均低于100IU/L。
实施例2、SIX1、EYA1、人血清白蛋和胶质纤维酸性蛋白的免疫荧光检测
本实施中,人或者转基因小鼠肝脏组织切片中SIX1、EYA1、人血清白蛋白HSA和胶质纤维酸性蛋白(glial fibrillary acidic protein,GFAP)的免疫荧光染色包括以下步骤:
将慢性肝炎患者的人或者转基因小鼠肝脏组织冰冻切片用100%乙醇固定15分钟,用0.05%吐温20通透化细胞两次,每次处理2分钟。然后在常温下用3%牛血清白蛋白阻断30分钟。用PBS洗涤后,用兔抗人SIX1一级抗体(1:100稀释度)(HPA001893,Sigma,St.Louis,MO USA)或兔抗人EYA1一级抗体(1:100稀释度)(ab85009,abcam,Cambridge,MA,美国)和小鼠抗人HSA一级抗体(1:1000稀释度)(MAB1455,R&D Systems,Minneapolis MN,USA)或小鼠抗人GFAP一级抗体(1:100稀释度)(MA5-12023,ThermoFisher,Waltham,MA,USA)在4℃过夜。
然后将切片与Alexa

驴抗鼠IgG和Alexa
Figure BDA0002911843480000092
驴抗兔IgG(1:1000稀释度)(A21202,A10042,ThermoFisher,Waltham,MA,USA)在常温下孵育1小时。
用PBS洗涤后,用4',6-二氨基-2-苯基吲哚(4’,6-diamidino-2-phenylindole,DAPI)对切片进行反染色。最后,用抗褪色介质贴上盖玻片,用奥林匹斯Olympus DP72显微镜和cellSens Standard 1.5软件观察并记录免疫荧光信号。
如图1至图3所示,慢性乙型肝炎患者肝脏组织免疫荧光染色显示SIX1和EYA1仅在肝星状细胞中表达,而且在慢性乙型肝炎组织中表达明显,但在正常肝组织中不明显。
本发明实施例在人Eya1LacZ转基因小鼠和Six1LacZ转基因小鼠上的研究发现Eya1和Six1基因主要在肝脏的卫星细胞中表达,Six1/Eya1基因与肝细胞的再生有关研究提示SIX1和EYA1都是慢性乙型肝炎和其他肝脏疾病肝损伤的新的生物标志物,具有潜在的临床应用价值。
虽然,上文中已经用一般性说明及具体实施例对本发明作了详尽的描述,但在本发明基础上,可以对之作一些修改或改进,这对本领域技术人员而言是显而易见的。因此,在不偏离本发明精神的基础上所做的这些修改或改进,均属于本发明要求保护的范围。
