本发明涉及生物技术领域,更具体地涉及尿液中进展期白癜风蛋白标志物在激素治疗疗效评估中的用途。
背景技术
白癜风是一种常见的获得性色素脱失性疾病,临床上以境界清楚的皮肤色素脱失斑为主要表现。根据白癜风病情发展情况,分为进展期和稳定期,患者常出现不可预测的稳定期和进展期的反复交替。由于其具有影响美观、病程较长、治疗抵抗的特点,严重影响了患者的身心健康和生活质量。目前系统性应用糖皮质激素广泛应用于抑制白癜风的快速进展并刺激皮肤复色。临床上,常根据进展期白癜风患者的治疗反应,决定糖皮质激素的应用疗程。长期使用糖皮质激素将影响内源性激素正常功能,并导致严重的副作用;而糖皮质激素用量不足,将会贻误病情,造成白斑进一步进展。目前,评估白癜风激素疗效以临床表现为主,缺乏能客观、准确评估白癜风激素治疗疗效的生物标志物。此标志物能够用来辅助判断激素使用疗程,制定个性化治疗方案,及时停药减少副作用,或及时调整药物干预方案避免贻误病情,具有重要的临床价值。
基于质谱技术的蛋白质组分析是大规模筛选各种体液中疾病相关蛋白质生物标记物的有力生物学方法。尿液是鉴定潜在生物标志物的理想标本,具有取材方便、简单、无创、快速、能够连续监测等优势。尿蛋白质组学已被广泛用于肿瘤、自身免疫性病等疾病的生物标记物的筛选。既往研究中,尿蛋白质组学的方法也被用于预测药物治疗的疗效。目前尚无利用尿蛋白组学生物标志物评估活动性白癜风激素治疗疗效的研究报道。
发明内容
为了解决上述技术问题,本发明的目的是在于提供与进展期白癜风激素治疗疗效评估相关的生物标志物,利用定量蛋白质组学技术手段,通过检测差异蛋白表达水平,可以判断患者经过激素治疗后疾病是否得到控制,从而为个体化治疗提供一种新的手段。

在本发明中,收集了非节段型进展期白癜风患者经激素治疗前后的尿液,采用液相色谱-高分辨质谱方法。通过PCA、OPLS-DA监督聚类分析,差异倍数分析和T检验分析,筛选出潜在的生物标志物,并通过酶联免疫吸附试验法进一步验证差异蛋白对疾病抵抗组和有效组之间治疗疗效预测有很好的区分,具有良好的临床应用前景。
本发明首次发现了能够评估进展期白癜风激素治疗疗效的蛋白标志物,通过检测蛋白标志物的含量,可以判断受试者经过激素治疗后疾病是否得到控制,制定个性化治疗方案,提高治疗疗效、减少不良反应、避免延误病情。

二、试验方法
1.1人尿液样品的收集
收集空腹晨尿,尿液样本5000g/min离心30min,去掉尿沉渣。
1.2尿液蛋白质提取
取离心后的尿液上清,上清液加入3倍体积的乙醇,经4℃沉淀2小时,10000g/min离心30min得到尿蛋白沉淀。沉淀加入裂解液溶解(7M尿素,2M硫脲,0.1M二硫苏糖醇和5mM三氨基甲烷(Tris)),37℃静置1小时,加入1mol/L的碘乙酰胺至终浓度0.05mol/L,室温避光45min。样本转移到10KD超滤膜上用缓冲液(7M尿素和50mM Tris)清洗两次之后,用25mM碳酸氢铵溶液再清洗两次。处理后的样品在25mM碳酸氢铵溶液中用胰蛋白酶消化。消化后的肽段从10KD的过滤器中洗脱,在C18柱上脱盐纯化。
1.3液相分析
样本及混合的质控样本肽段首先用高效液相色谱柱(4.6mm×250mm,3μm)进行预分离,多肽的洗脱液梯度为5%~35%B液(90%乙腈),流速为1mL/min,洗脱时间为30min。每分钟收集一个组分,抽干后溶解于0.1%甲酸水溶液,按照6~7,8~9,10~11,12~13,14~16,17~19,20~22和23~26将收集的组分合并为8个组分。

1.5质谱数据分析
质谱数据应用Spectronaut(Biognosys公司,版本14.3)软件进行数据库检索,数据库为SwissProt人类蛋白质组学数据库(www.uniprot.org,20121条序列)。搜索参数为:胰蛋白酶酶切,误切位点为2个,母离子和子离子的质量精确度分别为10ppm和0.02Da,固定修饰为半胱氨酸的脲基甲基化,可变修饰为甲硫氨酸氧化(+43.00Kn)。
三、结果
非监督PCA得分图(图1)显示激素治疗有效组和激素治疗抵抗组呈现出一定的区分度。进一步采用监督OPLS-DA构建模型(图2),两组区分度更加明显。将p<0.05确定为差异蛋白,共筛选出差异蛋白341个。经验证组进行验证后筛选出54个差异蛋白。结果显示治疗前抵抗组及有效组间人耐扭蛋白A相互作用蛋白-1(FC=0.35787),人蛋白二硫化物异构酶A4(FC=0.26298)具有统计学差异。
采用ROC曲线评估差异蛋白对激素治疗疗效的预测效果,结果显示人耐扭蛋白A相互作用蛋白-1,人蛋白二硫化物异构酶A4具有较好的预测价值,AUC值分别为0.7738和0.9524,预测效果良好,进一步使用随机森林模型评估人耐扭蛋白A相互作用蛋白-1和人蛋白二硫化物异构酶A4联合预测能力,AUC值为0.899(图3)。

1.3实验步骤
1)设置标准品孔,标准品孔各加入不同浓度的标准品50μl。
2)分别设空白孔(空白对照孔不加样品及酶标试剂,其余各步操作相同)、待测样品孔。在酶标包被板上待测样品孔中加样品50μl。将样品加于酶标板孔底部,尽量不触及孔壁,轻轻晃动混匀。每孔加入酶标试剂100μl。用封板膜封板后置37℃温育60分钟。

三、结果
ELISA结果显示,人耐扭蛋白A相互作用蛋白-1在治疗后抵抗组和有效组间均有统计学差异,和质谱的数据一致。在治疗有效组中,与治疗前相比,人耐扭蛋白A相互作用蛋白-1经过治疗后水平升高;在治疗抵抗组中,与治疗前相比,人耐扭蛋白A相互作用蛋白-1治疗后水平降低,与治疗有效组趋势相反(图4)。
人蛋白二硫化物异构酶A4在治疗后抵抗组和有效组间有统计学差异,和质谱的数据一致。在治疗有效组中,与治疗前相比,人蛋白二硫化物异构酶A4经过治疗后水平升高;在治疗抵抗组中,与治疗前相比,治疗后水平进一步降低,与治疗有效组趋势相反(图5)。
