文摘目的:制备针对白血病干细胞(LSC)表面标志蛋白IL1RAP(IL-1 receptor accessory protein)的特异性单克隆抗体并对其进行鉴定。方法:杂交瘤细胞3H6E10、10D8A7种植BALB/c小鼠腹腔,收获腹水,纯化后得到特异性抗人IL1RAP的单克隆抗体。分别应用非变性聚丙烯酰胺凝胶电泳(Nondenaturing-PAGE)、ELISA和Western blot法对纯化单克隆抗体分别进行抗体纯度、效价和敏感性检测。结果:获得了两种IL1RAP纯化单克隆抗体,命名为3H6E10 Mc Ab和10D8A7 Mc Ab,其纯度分别为95%和94%;两种纯化的单克隆抗体效价为1∶81000,且能特异性识别IL1RAP纯化蛋白、正常人及白血病病人的细胞内源性蛋白。结论:本研究成功制备了能特异性结合人IL1RAP的纯化单克隆抗体,为将来有效清除体内LSC提供了新途径。
文摘IL1B(Interleukin 1 beta)是一种对抗感染的前炎症因子,在肿瘤的发生发展中起着重要的作用。IL1B基因启动子区-31C/T多态性位点通过影响IL1B的转录参与癌症的发生。针对已有的研究存在结论不一致的现状,为了阐明两者之间的关系,我们对47篇发表的病例对照研究进行meta分析,其中包括11125病例和14415例对照。比值比(Odds Ratio,OR)和95%可信区间(CI)用来评估多态性位点与癌症风险的关联程度。在所有的对比中没有发现此多态性位点与所有癌症相关联。通过分层分析发现,携带C等位基因的个体比不带C等位基因的个体患肝癌的风险低(CCVS TT:OR=0.87,95%CI:0.77—0.98,Phetermgrenty=0.103;TC vs TT:OR=0.77,95%CI:0.62-0.95,Phetermgrenty=0.734;TC+CC vs TT:OR=0.74,95%CI:0.61~0.91,Phetermgrenty=0.472)。同样,C/C基因型个体相比T,T基因型个体患胃癌风险低(OR=0.87,95%CI:0.77-0.98,Rhetermgrenty=0.103)。运用隐性模型,患胃癌的风险显著下降(OR=0.88,95%CI:0.80~0.97,Phetermgrenty=0.158),在欧洲人群(OR=0.84,95%CI:0.73-0.97,Phetermgrenty=0.070)和感染-配埘研究(OR=0.75,95%CI:0.60~0.94,Phetermgrenty=0.220)中都发现有显著下降的风险;在乳腺癌中有显著增加的风险(OR=1.34,95%CI:1.18~1.61,Phetermgrenty=0.116)。虽然一些适度偏倚不能消除,此meta分析显示IL1B-3IC基因型是癌症发生的保护因素,特别是在感染人群中。
