摘要:

文题释义:
骨关节炎:是一种与慢性、低度炎症相关的退行性关节疾病,好发于中老年人群,常伴有关节疼痛、活动困难等症状,甚至会引起残疾而导致劳动力丧失。
坏死性凋亡:是一种由死亡受体介导、具有广泛炎症特性并受RIPK1-RIPK3-MLKL复合物严格调控的新型细胞死亡途径,可引发疼痛、细胞外基质受损及软骨破坏等典型骨关节炎表现。

背景:骨关节炎与慢性、低度炎症密切相关。坏死性凋亡是一种具有广泛炎症特性的新型细胞死亡途径,可影响骨关节炎进展,但目前尚未发现骨关节炎坏死性凋亡的相关靶点。
目的:基于生物信息学挖掘骨关节炎坏死性凋亡关键基因,并利用动物实验加以验证,为从坏死性凋亡角度防治骨关节炎提供新的靶点。
方法:分别从GEO数据库与GeneCards数据库筛选出骨关节炎相关基因和坏死性凋亡相关基因,继而对两者取交集获得骨关节炎坏死性凋亡基因,进一步进行GO及KEGG富集分析,构建PPI网络,通过Cytoscape软件的5种计算方法获得骨关节炎坏死性凋亡关键基因(Hub基因),最后选用雄性SD大鼠建立膝关节骨关节炎中期模型,通过RT-PCR检测Hub基因在SD大鼠骨关节炎中期模型中的表达情况。
结果与结论:①共筛选出38个骨关节炎坏死性凋亡基因,GO及KEGG分析发现其主要在白细胞活性、T细胞受体及白细胞介素17信号通路等方面显著富集;通过Cytoscape的5种不同算法筛选出CYBB、FADD、IL1B、MYC及EGFR 5个Hub基因;②RT-PCR检测结果显示,与正常对照组比较,雄性SD大鼠骨关节炎中期模型软骨中EGFR、IL1B基因呈高表达(P < 0.05),CYBB、MYC基因呈低表达(P < 0.05),FADD基因表达无明显变化(P > 0.05);③结果显示,CYBB、IL1B、MYC及EGFR可作为骨关节炎坏死性凋亡的关键基因,有望成为防治骨关节炎的新靶点。

Abstract: BACKGROUND: Osteoarthritis is closely related to chronic and low-grade inflammation. Necroptosis is a new cell death pathway with extensive inflammatory characteristics, which can affect the progression of osteoarthritis, but the related targets of necroptosis in osteoarthritis have not been found.
OBJECTIVE: To explore the key genes of necroptosis in osteoarthritis based on bioinformatics and verify them with animal experiments, so as to provide new targets for the prevention and treatment of osteoarthritis from the perspective of necroptosis. 
METHODS: Osteoarthritis- and necroptosis-related genes were screened from GEO database and GeneCard database respectively, and then the intersection of them was taken to obtain osteoarthritic necroptosis genes. Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were further carried out to construct a protein-protein interaction network. The key genes of osteoarthritic necroptosis (Hub genes) were identified through five calculation methods using Cytoscape software. Finally, male  Sprague-Dawley rats were selected to metaphase models of osteoarthritis. The expression of Hub genes in the metaphase models of osteoarthritis of male Sprague-Dawley rats detected by RT-PCR. 
RESULTS AND CONCLUSION: A total of 38 osteoarthritic necroptosis genes were identified. Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses showed that they were significantly enriched in leukocyte activity, T cell receptor and interleukin-17 signal pathway. Five Hub genes, CYBB, FADD, IL1B, MYC and EGFR, were screened by the five different algorithms of Cytoscape. RT-PCR showed that EGFR and IL1B were highly expressed in the metaphase models of osteoarthritis of male  Sprague-Dawley rats (P < 0.05), while CYBB and MYC were lowly expressed (P < 0.05), but FADD had no significant changes (P > 0.05). To conclude, CYBB, IL1B, MYC, and EGFR, as the key genes of osteoarthritic necroptosis, are expected to become new targets for the prevention and treatment of osteoarthritis.
