Description
技术领域
本发明涉及生物医药领域,具体涉及PRIMA1基因在制备椎间盘退行性疾病诊断试剂中的应用。
背景技术
椎间盘退行性疾病是指椎间盘组织在多种原因综合作用下发生细胞介导的生物化学变化,引起老化加速、椎间盘力学特性改变,使临近骨关节、韧带发生相应变化,造成脊柱不稳,压迫脊髓、神经根、动脉,引起相应临床症状和体征的综合征。它包括椎间盘源性腰痛、椎间盘突出症、退行性脊椎不稳症、退行性椎管狭窄症、退行性滑脱症等,是临床上常见疾病之一。其病因尚不清楚,目前普遍认为椎间盘退行性疾病的发生是遗传和环境因素共同作用的结果。随着基因检测技术的发展,近年来,人们逐渐意识到遗传易感性即遗传因素对于揭示椎间盘退行性疾病发病的重要作用。
目前椎间盘退行性疾病一般采取保守治疗,即从保守治疗依次到微创、常规手术治疗、非融合固定治疗、融合固定治疗的阶梯。越是高级阶梯的治疗,创伤越大,对机体自然解剖状态的干预越大,每一高级阶梯的治疗可作为对相对低级阶梯治疗的补救措施。对患者采取的治疗方案要根据患者病情所处的阶段,同时也要考虑到患者个体因素,如创伤、风险、费用以及患者的意愿。但是无论哪种手术方式,均不能在椎间盘退变的早期进行有效地干预,不能延缓或逆转疾病的发展。开放手术(椎间盘切除融合内固定术)虽能较为彻底的切除退变椎间盘,但手术创伤大,费用高,内固定限制了脊柱的活动度,加速邻近节段椎间盘的退变。微创手术不能彻底切除退变椎间盘组织,术后症状可能不能完全缓解,术后复发的可能性较大。

具体实施方式
以下实施例用于说明本发明,但不用来限制本发明的范围。若未特别指明,实施例中所用的技术手段为本领域技术人员所熟知的常规手段。
实施例中未注明具体条件的实验方法,通常为本领域常规方法,如按照常规条件如Sambrook等人,分子克隆,实验手册(第三版)(科学出版社,2002)中的所述条件,或按照试剂制造厂家所建议的条件。
本发明的发明人对10例椎间盘退行性疾病患者的髓核组织样本及4例对照样本进行高通量测序,结果发现,椎间盘退行性疾病患者的髓核组织中PRIMA1基因的水平与对照相比显著下调。进一步地,发明人采用TaqMan实时荧光定量PCR方法验证了PRIMA1基因在椎间盘退行性疾病患者髓核组织中表达下调,其相关制剂可用于椎间盘退行性疾病。
PRIMA1(proline rich membrane anchor 1,脯氨酸丰富的膜锚1)位于14号染色体上,是蛋白编码基因,能将乙酰胆碱酯酶组装成四聚体,并将其锚定在神经细胞膜上。
实施例1筛选与椎间盘退行性疾病相关的基因标志物
1、样本收集
取2012年10月到2015年12月期间在北京协和医院骨科收集10例椎间盘退行性疾病患者作为实验组,对照组来源于同时期骨科住院的其他疾病患者,共收集4例。上述所有标本的取得均通过组织伦理委员会的同意。获取所有研究对象椎间盘髓核组织,编号后置-80℃低温冰箱保存。
2、对髓核组织进行总RNA提取
收集样本后冻存于液氮,取出后把髓核组织放入已预冷的研钵中进行研磨,待组织样本成粉末状后:
①加入Trizol,室温保存5分钟;
②加氯仿0.2mL,用力振荡离心管,充分混匀,室温下放置5分钟-10分钟;
③12000rpm高速离心15分钟后吸取上层水相(吸70%)到另一新离心管管中,注意不要吸到两层水相之间的蛋白物质。移入新管,加入等体积的-20℃预冷异丙醇,充分颠倒混匀,置于冰上10分钟;
④12000rpm高速离15分钟后小心弃掉上清液,按1mL/mL Trizol的比例加入75%DEPC乙醇洗漆沉淀(4℃保存),洗漆沉淀物,振荡混合,4℃下12000rpm高速离心5分钟;
⑤弃去乙醇液体,室温下放置5分钟以充分晾干沉淀,加入DEPC处理过的水溶解沉淀;
⑥用Nanodrop2000紫外分光光度计测量RNA纯度及浓度,冻存于-80℃。RNA质量判定标准:RNA样本的OD260/OD280值为1.7-2.2之间;总RNA电泳图谱有清晰的28S、18S条带;70℃水浴保温1小时后的电泳图谱与水浴保温前的图谱无明显差异。
3、RNA样品的质量分析
RNA提取后琼脂糖凝胶电泳,从电泳结果可以初步判定提取的RNA样品质量合格与否,是否可以用于进一步的转录组分析。进而通过NanoDrop1000分光光度计检测RNA样品的提取情况,RNA-seq测序的样品要求:OD260/OD280为1.8-2.2。
4、高通量测序
测序平台为Illumina公司的HiSeq 2500高通量测序平台,进行高通量转录组深度测序,测序后我们运用Fast-QC(http://www.bioinformatics.babraham.ac.uk/projects/fastqc/)软件对测序数据的质量进行整体评估,包括碱基的质量值分布,质量值的位置分布,GC含量,PCR duplication含量,kmer的frequency等。在差异基因表达分析时,根据得到的FPKM值,采用国际公认算法EBSeq进行差异筛选。其中,筛选时,LOG2FC>1或<-1,FDR<0.05。为了更好的理解差异表达基因的功能,我们对差异表达基因进行了Gene Ontology和信号通路分析,并对差异表达基因进行功能注释和蛋白质互相作用网络分析,鉴于以上数据分析的结果,结合文献我们筛选了差异表达基因PRIMA1,该基因在髓核组织样本中表达下调。
实施例2TaqMan实时荧光定量PCR验证椎间盘退行性疾病患者PRIMA1基因的表达情况
1、材料

3、统计学分析
实时定量PCR扩增曲线拐点清楚,扩增曲线整体平行性好,表明各反应管的扩增效率相近,基线平而无上扬现在,曲线指数期斜率较大,说明扩增效率较高;采用2-ΔΔCt法分析结果,根据qRT-PCR的相对定量公式:2-ΔΔCt×100%,比较PRIMA1基因在椎间盘退行性疾病患者髓核组织和对照组髓核组织中的表达水平。结果显示:qRT-PCR扩增结果稳定,其中PRIMA1基因在椎间盘退行性疾病组织表达水平明显低于对照组,约是对照组的35%,具体见图1,以上结果验证了高通量测序分析的结果。

结果显示,pcDNA3.1-PRIMA1组细胞生长速度明显高于pcDNA3.1空载体组和空白对照组细胞生长速度,差异具有统计学意义(P<0.05),上述结果表明PRIMA1基因过表达能促进椎间盘髓核细胞的生长,具体情况见图3。
