摘要:


文题释义:

绝经后骨质疏松:是一种与衰老有关的常见病,主要发生在绝经后妇女,由于雌激素缺乏导致骨量减少及骨组织结构变化,使骨脆性增多,易于骨折。
抗体芯片:蛋白芯片的一种,具有微型化、集成化、高通量化的特点,可以用于检测某一特定的生理或病理过程相关蛋白的表达丰度,主要用于信号转导、蛋白质组学、肿瘤及其他疾病的相关研究。


背景:近年来,绝经后骨质疏松症骨骼与免疫系统之间相互作用机制的研究已成为热点,但关键免疫相关因子表达改变对绝经后骨质疏松症的影响尚不明确,仍需进一步探索。

目的:通过生物信息学方法探讨绝经后骨质疏松症小鼠骨髓间充质干细胞免疫相关因子差异化表达情况。
方法:通过卵巢切除手术构建绝经后骨质疏松症小鼠模型,采用全骨髓贴壁法获取骨髓间充质干细胞并稳定传代至第2代,使用RayBio L-Series Mouse Antibody Array 308 Glass Slide Kit免疫相关因子抗体芯片检测卵巢切除组及假手术组小鼠骨髓间充质干细胞中存在差异表达的蛋白,对检测结果进行GO、KEGG富集分析及PPI网络分析,通过MCC、EPC及MNC算法所得值筛选共同的Hub基因。

结果与结论:共获得68个差异表达基因。GO分析发现差异表达基因富集于免疫系统过程、胞外区、信号受体结合等条目。KEGG分析发现差异基因主要富集于细胞因子-细胞因子受体的相互作用、肿瘤坏死因子信号通路和趋化因子信号通路等条目。通过对68个差异表达基因构建PPI网络分析进一步筛选得到了8个Hub基因,绘制小提琴图和相关性矩阵发现8个Hub基因的表达水平在卵巢切除组均较假手术组显著下调。结果显示,绝经后骨质疏松症小鼠骨髓间充质干细胞存在差异性表达的免疫相关因子,筛选得到其中的关键基因主要涉及细胞因子-细胞因子受体的相互作用、免疫系统相关过程等具有潜在靶向的信号通路及细胞生物学过程,为绝经后骨质疏松症的诊治和预防提供新的靶点。

Abstract: BACKGROUND: In recent years, research on the interaction mechanism between the immune system and the skeleton in postmenopausal osteoporosis has become a hot topic. However, the impact of changes in key immune-related cytokine expression on postmenopausal osteoporosis remains unclear and requires further exploration. 
OBJECTIVE: To investigate the differential expression of immune-related cytokines in bone marrow mesenchymal stem cells of mice with postmenopausal osteoporosis by bioinformatics methods. 
METHODS: Postmenopausal osteoporosis mouse model was established through ovariectomy. Bone marrow mesenchymal stem cells were obtained by the whole bone marrow adherence method and passaged to passage 2. RayBio L-Series Mouse Antibody Array 308 Glass Slide Kit immune-related factor antibody chip was used to detect the differentially expressed proteins in bone marrow mesenchymal stem cells from ovariectomy and sham-operation mice. Gene ontology, Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and protein-protein interaction network analysis were performed to screen common Hub genes by MCC, EPC, and MNC algorithms.
RESULTS AND CONCLUSION: This study identified a total of 68 differentially expressed genes. Gene ontology analysis revealed that the differentially expressed genes were enriched in terms including “immune system processes”, “extracellular regions”, and “signal receptor binding”. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that the differentially expressed genes were mainly enriched in “cytokine-cytokine receptor interactions”, “tumor necrosis factor signaling pathways”, and “chemokine signaling pathways”. Further screening was performed by constructing a protein-protein interaction network analysis of these 68 differentially expressed genes to identify 8 Hub genes. The violin plot and correlation matrix showed that the expression levels of these 8 Hub genes were significantly down-regulated in the ovariectomy group compared to the sham-operation group. These results demonstrated that there was differential expression of immune-related factors in bone marrow mesenchymal stem cells of postmenopausal osteoporosis mice, and key genes involved in cytokine-cytokine receptor interactions, immune system-related processes, and potential targeted signaling pathways and cellular biological processes were identified, providing new promising targets for the diagnosis, treatment, and prevention of postmenopausal osteoporosis.
