目的:分析维吾尔族与汉族假性剥脱综合征性白内障(PXEC)患者房水蛋白质表达差异。方法:分别收取2020年6月至2021年1月在和田地区人民医院拟手术治疗的新疆维吾尔族PXEC患者(U组)与天津医科大学眼科医院拟手术治疗的汉族PXEC患者(H组)房水样本各6例,采用非标记定量蛋白质组学技术对两组房水中的蛋白进行鉴定和定量分析,筛选出差异蛋白并通过基因本体(GO)功能分析、京都基因与基因组百科全书(KEGG)信号通路分析两组患者房水中差异蛋白的功能及调控的信号通路。利用STRING数据库建立蛋白-蛋白互作(PPI)网络,使用Cytoscape软件中MCODE插件识别PPI中的枢纽蛋白。结果:本次研究共鉴定出629个蛋白。以差异倍数>2且P<0.05为标准共筛选出123种差异表达蛋白,与H组相比,U组下调蛋白92种,上调蛋白31 种。GO分析和KEGG分析发现,这些差异蛋白主要集中在补体及凝血级联通路、细胞外基质受体相互作用通路、系统性红斑狼疮通路、焦点黏附通路、阿米巴病通路、血小板激活通路、溶酶体通路、胆固醇代谢通路和多种类型的N-聚糖生物合成等通路。通过PPI筛选出17种枢纽蛋白,其中包括纤维连接蛋白(FN1)、载脂蛋白E(ApoE)、淀粉样β蛋白前体(APP)、玻连蛋白(VTN)、簇集蛋白(CLU)、载脂蛋白A-Ⅳ(ApoA4)、补体C4A(C4A)、补体C4B(C4B)、凝血因子12(F12)、纤维蛋白原α链(FGA)、纤维蛋白原β链(FGB)、纤维蛋白原γ链(FGG)、激肽原-1(KING1)、富组氨酸糖蛋白(HRG)、补体C8A(C8A)、视黄醇结合蛋白4(RBP4)与肝素辅因子2(SERPIND1),MCODE 分数为12.375。结论:ApoA4、FGA、FGB、FGG等17种枢纽蛋白主要涉及补体及凝血级联通路与胆固醇代谢通路,提示两民族在胆固醇代谢与炎症调节方面存在生物学差异 。

Objective: To analyze the difference of aqueous humor protein expression in pseudoexfoliation syndrome cataract (PXEC) between Uygur and Han patients. Methods: Six aqueous humor samples were collected from Xinjiang Uygur PXEC patients undergoing surgical treatment in Hotan Regional People′s Hospital(group U) and Han PXEC patients(group H) undergoing surgical treatment in the Eye Hospital of Tianjin Medical University from June 2020 to January 2021, respectively. Non-label quantitative proteomics was used to identify and quantitatively analyze the proteins in aqueous humor of the two groups, the differential proteins were screened out, and the functions and regulatory signaling pathways of the differential proteins in aqueous humor of the two groups were analyzed by gene ontology(GO) function analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) signaling pathway. The protein-protein interaction (PPI) network was established using STRING database, and MCODE plug-in in Cytoscape software was used to identify the hub proteins in PPI network. Results: In this study, a total of 629 proteins were identified. A total of 123 differentially expressed proteins were screened with the difference ratio>2 and P<0.05. Compared with group H, 92 proteins were down-regulated and 31 proteins were up-regulated in group U. Gene Ontology(GO) analysis and the Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis of these di-fferential proteins focused on the complement and coagulation grade pathway, extracellular matrix receptor interaction pathway, systemic lupus erythematosus pathway, focal adhesion pathway, amoebiasis pathway, platelet activation pathway, lysosomal pathway, cholesterol metabolism pathway, and various types of N-Chitosan biosynthesis and other pathways. 17 hub proteins were screened through PPI network, including fibronectin(FN1), apolipoprotein E(ApoE), amyloid beta protein precursor(APP), vitronectin(VTN), cluster(CLU), apolipoprotein A-Ⅳ(ApoA4), complement C4A(C4A), complement C4B(C4B), Coagulation factor XII(F12), fibrinogen alpha chain(FGA), fibrinogen beta chain(FGB),fibrinogen gamma chain(FGG), kininogen 1(KING1), histidine-rich glycoprotein(HRG), com-
plement C8A(C8A), retinol-binding protein 4(RBP4), andHeparin cofactor 2(SERPIND1), with an MCODE Score of 12.375. Conclusion: The 17 hub proteins, including ApoA4, FGA, FGB and FGG, are mainly involved in complement and clotting pathway and cholesterol metabolism pathway, suggesting that there are biological differences in cholesterol metabolism and inflammation regulation between the two ethnic groups.
