摘要:

文题释义:
滑膜炎:是指滑膜受到刺激产生炎症,造成分泌液失调形成积液的一种关节病变。常见的滑膜炎有两种:非特异性滑膜炎和特异性滑膜炎等。膝关节是全身关节中滑膜最多的关节,故滑膜炎以膝关节较为多见。
血管内皮生长因子A:是骨发育过程中的重要调因子,骨关节炎晚期的关节软骨和滑膜中血管内皮生长因子表达明显增加。它参与了骨关节炎的软骨变性、骨赘形成、软骨下骨囊肿和硬化、滑膜炎等特异性病变过程,在白细胞介素1β的协同下,血管内皮生长因子能够显著降低聚集蛋白聚糖和Ⅱ型胶原蛋白的基因表达和蛋白质水平,而抑制血管内皮生长因子A信号传导可延缓骨关节炎进展。

背景:研究发现超过90%的骨关节炎患者被证实存在滑膜病变,滑膜炎的发生还可能促进软骨退变。寻找滑膜病变的产生机制有助于找到精确的治疗靶点,获得良好预后。
目的:通过生物信息学途径,探究骨关节炎发生发展过程中滑膜组织的关键基因,为骨关节炎的研究提供新的思路。 
方法:从公共数据库GEO下载骨关节炎滑膜相关芯片数据集GSE82107、GSE12021、GSE55457、GSE55235,纳入骨关节炎滑膜组织40例,正常滑膜组织36例。利用R软件筛选差异表达基因、GO功能富集以及KEGG通路富集分析,STRING在线分析工具及Cytoscape软件进一步筛选关键基因。
结果与结论:①共筛选出骨关节炎与健康对照之间的差异表达基因447个,其中上调201个,下调246个;这些基因主要富集在炎症反应、细胞外基质、胶原蛋白、血管发育的调控等功能以及MAPK信号通路、肿瘤坏死因子信号通路、花生四烯酸代谢等方面;分析蛋白质相互作用后筛选出基质金属蛋白酶9、白细胞介素6、血管内皮生长因子A、JUN、前列腺素内过氧化物合酶2、CXCL8、MYC、表皮生长因子受体8个关键基因;②利用生物信息学分析所筛选出来的关键基因血管内皮生长因子A、基质金属蛋白酶9、JUN、前列腺素内过氧化物合酶2可能成为骨关节炎诊断的生物学标志物以及治疗的潜在靶点。

Abstract: BACKGROUND: Over 90% of patients with osteoarthritis suffer from synovial lesions, and the occurrence of synovitis may also promote cartilage degeneration. To explore the potential mechanisms of synovial lesions is beneficial to find precise treatment targets and achieve good long-term prognosis.
OBJECTIVE: To identify candidate hub genes in the synovial tissues during the development of osteoarthritis by bioinformatics analysis, and to further provide new insights for osteoarthritis study.
METHODS: The osteoarthritis synovial-associated chip data sets GSE82107, GSE12021, GSE55457, and GSE55235 were downloaded from the public database GEO, including 40 cases of osteoarthritic synovial tissue and 36 cases of normal synovial tissue. R software was used to screen differentially expressed genes  using Gene ontology function enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and hub genes are selected by STRING online analysis tool and Cytoscape software.
RESULTS AND CONCLUSION: Total 447 differentially expressed genes were selected between osteoarthritis and healthy control, including 201 up-regulated and 246 down-regulated genes. These differentially expressed genes were mainly enriched in inflammatory response, regulations of extracellular matrix, collagen, blood vessel development, as well as MAPK signaling pathway, tumor necrosis factor signaling pathway, arachidonic acid metabolism. Eight hub genes were screened by analyzing the protein interactions, which included matrix metalloproteinase 9, interleukin 6, vascular endothelial growth factor A, JUN, prostaglandin peroxide enzyme 2, CXCL8, MYC, epidermal growth factor receptor. The hub genes selected by bioinformatics analysis such as vascular endothelial growth factor A, matrix metalloproteinase 9, JUN, and prostaglandin peroxidase 2 may be biomarkers for the diagnosis of osteoarthritis and potential targets for treatment.
