目的

探讨高度近视眼(HM)与糖尿病视网膜病变(DR)发生风险呈负相关的分子机制。

方法

选取2019年3月至10月于同济大学附属杨浦医院眼科就诊的18例患者作为研究对象。其中,男性10例,女性8例;年龄64~77岁,平均年龄(70.1±4.3)岁。收集HM患者6例、增殖性糖尿病视网膜病变(PDR)患者6例及对照受试者6例血液样本,提取并鉴定血浆细胞外囊泡,采用蛋白定量和非标记液相色谱串联质谱分析,得到差异表达蛋白。使用基因注释功能富集、京都基因及基因组百科全书通路富集等生物信息学分析方法分析差异表达蛋白的功能。构建形觉剥夺性近视小鼠模型及DR小鼠模型,并用蛋白质免疫印迹法对关键差异蛋白进行组间验证。

结果

HM者、增殖性糖尿病视网膜病变(PDR)者及对照受试者共检测到血浆细胞外囊泡蛋白质852种。相对对照受试者,HM和PDR者血浆细胞外囊泡标本中分别发现16种特异性蛋白和6种特异性蛋白,共有蛋白700种。差异表达蛋白25项。HM者相对对照受试者有75种差异表达蛋白,包括20种上调蛋白和55种下调蛋白。差异蛋白主要富集在免疫应答及细胞外基质相关通路。其中,关键蛋白E3泛素蛋白连接酶Itchy同源物(ITCH)在HM组中表达上调,PDR者中表达下调。HM者相对对照组受试者和PDR者差异蛋白的蛋白质-蛋白质相互作用网络中分别有46个节点和69个节点,320个边界和676个边界。该趋势与动物模型的巩膜组织表达相一致。

结论

HM者对于DR的发生与发展具有潜在抑制作用,ITCH可能通过调控炎症通路和视网膜血管生成参与此过程。ITCH在两种疾病中的差异性表达及潜在机制路径解释了HM伴糖尿病患者发生DR程度轻和风险低的临床现象。

Objective

The aim of this study is to investigate the specific molecular mechanism of high myopia (HM) is correlated with a lower risk of diabetic retinopathy (DR).

Methods

A total of 18 patients who visited the Department of Ophthalmology, Yangpu Hospital Affiliated to Tongji University from March to October 2019 were enrolled as study subjects, including 10 males and 8 females with a mean age of (70.1±4.3) years (ranging from 64 to 77 years). Blood samples were collected from 6 patients with HM, 6 patients with proliferative diabetic retinopathy (PDR), and 6 control subjects. Extracellular vesicles were isolated and characterized, then proteomic analysis was performed using liquid chromatography-tandem mass spectrometry with label-free quantification. Bioinformatics methods, including Gene Ontology functional enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment, were applied to analyze the functions of the differentially expressed proteins. Additionally, a form-deprivation myopia mouse model and a DR mouse model were established, and key proteins were validated by Western blot.

Results

A total of 852 proteins of extracellular vesicles were identified in the proteomic data. Compared with control subjects, 16 specific proteins were identified in plasma extracellular vesicle specimens from HM patients and 6 specific proteins from PDR patients, with 700 common proteins. A total of 25 differentially expressed proteins were found. Compared with control subjects, HM patients had 75 differentially expressed proteins, including 20 up-regulated proteins and 55 down-regulated proteins. These proteins were mainly enriched in immune response and extracellular matrix-related pathways. Among them, the key protein E3 ubiquitin-protein ligase Itchy homolog (ITCH) was up-regulated in the HM group and down-regulated in the PDR group. The protein-protein interaction network of differential proteins in HM patients compared with control subjects contained 46 nodes and 320 edges. The differential proteins in HM patients compared with PDR patients contained 69 nodes and 676 edges in the protein-protein interaction network. A consistent expression trend occurred in scleral tissues of animal models.

Conclusions

HM may potentially inhibit the occurrence and progression of DR, and ITCH is likely involved in this process by regulating inflammatory pathways and retinal angiogenesis. The differential expression of ITCH in the two diseases and its underlying mechanistic pathways provide a new perspective for explaining the clinical observation that diabetic patients with HM tend to have milder DR and a lower risk of its progression.
