摘要:

文题释义:
骨肉瘤:是一种好发于儿童和青少年的原发性恶性肿瘤,死亡率非常高。随着对骨肉瘤发病机制认识的不断深入和诊疗技术的发展,骨肉瘤患者5年生存率已由低于20%升高到50%-60%,但对于发生肺转移或局部复发者,预后仍极差。
miRNA:是长度约为22个核苷酸的非编码单链RNA分子,参与细胞发育、分化和细胞周期等生物过程,在肿瘤的发生机制中发挥重要作用。由于miRNA与肿瘤的发生、发展密切相关,因而阐明miRNA在骨肉瘤中的作用机制,有利于为治疗靶点提供一个新的方向。

背景:骨肉瘤是常见的原发性恶性肿瘤,其极易转移及预后较差;miRNA调控基因的表达参与骨肉瘤的发生与发展,但其潜在的miRNA-mRNA 调控网络尚未全面建立。
目的:通过生物学分析方法,构建骨肉瘤发病机制中潜在miRNA-mRNA调控网络,以便更全面地阐明骨肉瘤的发病机制。
方法:从GEO数据库获取miRNA微阵列数据集(GSE65071),利用GEO2R对20个骨肉瘤血浆样本和15个健康者血浆样本的数据进行差异表达分析,筛选出在骨中有靶向基因的差异表达miRNA,并预测差异表达miRNA潜在转录因子。同时,从GEO数据库获得GSE16088数据集并在线分析获取差异表达基因,将靶基因与差异表达基因交集获得目标基因。最后,对目标基因进行GO注释和KEGG通路富集分析,构建PPI网络和筛选出关键基因,进一步评估关键基因的表达。
结果与结论:共筛选出8个上调差异表达miRNA和14个下调差异表达miRNA,其主要转录因子有EGR1、POU2F1、SP1、SP4、NFIC、LHX3。22个差异表达miRNA靶基因与差异表达基因交集共获得110个目标基因。KEGG途径分析显示目标基因主要涉及细胞衰老、Apelin信号通路和癌症中的蛋白聚糖等途径。PPI网络分析显示CCNB1、AURKA、CD44较为重要。结果显示,通过构建骨肉瘤发病相关潜在miRNA-mRNA调控网络,为深入研究骨肉瘤分子机制提供理论基础,也为开发新的治疗靶标提供科学依据。

Abstract: BACKGROUND: Osteosarcoma is a common primary malignant tumor, which is easy to metastasize and has a poor prognosis. MicroRNA (miRNA) regulates gene expression to participate in the occurrence and development of osteosarcoma, but its potential miRNA-mRNA regulatory network has not been fully established.   
OBJECTIVE: To build a potential miRNA-mRNA regulatory network in the pathogenesis of osteosarcoma through bioinformatic analysis in order to comprehensively clarify the pathogenesis of osteosarcoma. 
METHODS: GEO2R tool was used to perform differential expression analysis on the data of 20 osteosarcoma plasma samples and 15 healthy plasma samples, based on the miRNA microarray dataset (GSE65071) from the GEO database. Differentially expressed miRNAs with targeted genes in bone were screened, and potential transcription factors for differentially expressed miRNAs were predicted. Simultaneously, the GSE16088 dataset was obtained from the GEO database and analyzed online to obtain differentially expressed genes, and the target genes were intersected with the differentially expressed genes to obtain the desired genes. Finally, gene oncology (GO) annotation and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway enrichment analysis were performed. Protein-protein interaction network was then established, and hub genes were screened. The expression of hub genes was further evaluated. 
RESULTS AND CONCLUSION: A total of 8 up-regulated and 14 down-regulated differentially expressed miRNAs were screened. The major transcription factors were EGR1, POU2F1, SP1, SP4, NFIC, and LHX3. In total, 110 desired genes were obtained by the intersection of 22 target genes with differentially expressed miRNA and differentially expressed genes. KEGG pathway analysis showed that the desired genes were mainly involved in cellular senescence, Apelin signaling pathway and proteoglycans in cancer. Protein-protein interaction network analysis showed that CCNB1, AURKA, and CD44 were more important. By constructing a potential miRNA-mRNA regulatory network related to osteosarcoma pathogenesis, it provides a theoretical basis for the in-depth study of osteosarcoma molecular mechanism and also provides a scientific basis for the development of new therapeutic targets.
