摘要:

文题释义:
ceRNA 网络:目前指出引起骨软骨关节炎的可能的原因包括:软骨退变、自我吞噬、机械力学改变、软骨过度增生、内部免疫、氧化应激、疼痛等。
基因芯片:基因芯片的测序原理是杂交测序方法,即通过与一组已知序列的核酸探针杂交进行核酸序列测定的方法,在一块基片表面固定了序列已知的靶核苷酸的探针。

背景:目前指出引起骨软骨关节炎的可能的原因包括:软骨退变、自我吞噬、机械力学改变、软骨过度增生、内部免疫、氧化应激及疼痛等。
目的:骨性关节炎由多种因素导致关节软骨退行性疾病,实验旨在通过生物信息学方法探讨骨性关节炎的发病机制。
方法:检索GEO数据库中关于骨性关节炎的相关芯片数据集GSE51588和GSE19060,借助R语言分析差异基因,利用miRDB,miRTarbase和starBase数据库分别预测骨性关节炎相关mRNA的靶向miRNAs,构建miRNA-mRNA调控网络,采用GeneMANIA和FUNRICH对上述调控网络中的mRNA进行分析;检索LncRNADisease病数据库与骨性关节炎相关的lncRNA,利用Starbase数据库预测其miRNAs,构建lncRNA-miRNA-mRNA ceRNA调控网络。
结果与结论:①利用R语言分析共筛选出11个显著差异mRNA;②通过miRDB,miRTarbase和starBase和预测的靶向miRNA与上述11个差异mRNA交叉映射确定290个miRNAs参与骨性关节炎相关miRNA-mRNA调控网络的构建;③在LncRNADisease数据库中检索到15个与骨性关节炎发病相关的IncRNA;④利用Starbase数据库预测270个miRNAs,构建出5个IncRNA,106个miRNA和8个mRNA的lncRNA-miRNA-mRNA ceRNA调控网络,通过FUNRICH得出7个主要的生物学过程和2条主要的信号通路;⑤进一步分析显示,差异表达mRNA主要和蛋白代谢作用、细胞通讯、信号转导、免疫反应、新陈代谢、能量途径及细胞生长的生物学过程有关,通过而参与骨性关节炎的发病过程,为骨性关节炎治疗靶点的确定提供了思路。

Abstract: BACKGROUND: The possible causes of osteochondroarthritis have been identified as cartilage degeneration, autophagy, mechanical changes, cartilage hypertrophy, internal immunity, oxidative stress, and pain. 
OBJECTIVE: To explore the pathogenesis of osteoarthritis that is a degenerative disease of articular cartilage caused by a variety of factors.
METHODS: GSE51588 and GSE19060, the chip data sets related to osteoarthritis in GEO database, were retrieved, and differential genes were analyzed with the help of R language. miRDB, miRTarbase and starBase databases were used to predict the targeted miRNAs of osteoarthritis related mRNAs respectively, and miRNA-mRNA regulatory network was constructed. GeneMANIA and FUNRICH were used to analyze the mRNAs mentioned in the regulatory network. lncRNA-miRNA-mRNA ceRNA regulatory network was constructed by retrieving LncRNADisease database and osteoarthiritis related IncRNA, using Starbase database to predict their miRNAs. 
RESULTS AND CONCLUSION: A total of 11 significantly differentially expressed mRNAs were screened by R language analysis. Through the cross-mapping of miRDB, miRTarbase and starBase and the predicted targeted miRNAs and the above 11 differentially expressed mRNAs, 290 miRNAs were identified to be involved in the construction of the miRNA-mRNA regulatory network related to osteoarthritis. Fifteen incRNAs related to the pathogenesis of osteoarthritis were retrieved in the LncRNADisease database, 270 miRNAs were predicted using Starbase database, and the lncRNA-miRNA-mRNA ceRNA regulatory network consisting of 5 IncRNAs, 106 miRNAs and 8 mRNAs was constructed. Seven major biological processes and two major signaling pathways were obtained through FUNRICH. Finding from our further analysis indicate that differentially expressed mRNA is mainly related to the biological processes of protein metabolism, cell communication, signal transduction, immune response, metabolism, energy pathway and cell growth. By participating in the pathogenesis of osteoarthritis, it provides ideas for the determination of therapeutic targets for osteoarthritis.
