摘要:


文题释义:
原发性骨质疏松症:骨质疏松是一种代谢性骨病变,以骨密度降低、骨组织微结构破坏为特征,会增加骨折的风险。根据病因可分为原发性和继发性,原发性骨质疏松症包括绝经后型、老年型、青少年型和特发性,继发性骨质疏松则由骨代谢相关的疾病或药物引起。
生物信息学:利用信息学、统计学和计算机科学等多学科的方式研究生物学的问题。研究方法包括利用生物算法与相关软件工具来进行生物学数据的搜索、数据的处理及计算结果。目前生物信息学在医学研究尤其是探究疾病的发生机制及转化中发挥着至关重要的作用。

背景:原发性骨质疏松症的发病率高,但发病机制尚不完全清楚,目前尚缺乏有效的早期筛查指标和治疗方案。
目的:通过综合生物信息学分析,进一步探索原发性骨质疏松症的发生机制。
方法:原发性骨质疏松症数据来自公共基因表达数据库,筛选差异基因分别进行GO功能和KEGG通路富集分析。此外,将差异基因进行蛋白质-蛋白质相互作用网络确定原发性骨质疏松症相关核心基因,并通过最小绝对收缩和选择运算算法来识别并验证原发性骨质疏松症相关的生物标志物,并分别进行免疫细胞相关分析、基因富集分析以及药物标靶网络分析。最后将生物标志物行qPCR实验验证。
结果与结论:①该研究中共获得126个差异基因以及前列腺素、表皮生长因子受体、丝裂原活化蛋白激酶3、转化生长因子B1和视网膜母细胞瘤基因1等5个生物标志物。②GO分析表明差异基因主要富集在细胞对氧化应激的反应以及自噬的调节等方面;KEGG分析显示主要集中在自噬以及细胞衰老等通路当中。③生物标志物的免疫分析发现,前列腺素,视网膜母细胞瘤基因1、丝裂原活化蛋白激酶3与免疫细胞密切相关。④基因富集分析表明,生物标志物与免疫相关途径有关。⑤药物标靶网络分析显示5个生物标志物与原发性骨质疏松症药物相关。⑥qPCR结果表明,前列腺素、表皮生长因子受体、丝裂原活化蛋白激酶3和转化生长因子B1在原发性骨质疏松症样本中,与对照样本相比表达显著上升(P < 0.001),而视网膜母细胞瘤基因1在原发性骨质疏松症样本中,与对照样本相比表达显著下降(P < 0.001)。⑦总之,该研究筛选并验证了5个原发性骨质疏松潜在生物标志物,为进一步深入探究原发性骨质疏松症的发病机制、早期筛查诊断及靶向治疗提供了参考依据。

Abstract: BACKGROUND: Primary osteoporosis has a high incidence, but the pathogenesis is not fully understood. Currently, there is a lack of effective early screening indicators and treatment programs.
OBJECTIVE: To further explore the mechanism of primary osteoporosis through comprehensive bioinformatics analysis.

METHODS: The primary osteoporosis data were obtained from the gene expression omnibus (GEO) database, and the differentially expressed genes were screened for Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. In addition, the differentially expressed genes were subjected to protein-protein interaction network to determine the core genes related to primary osteoporosis, and the least absolute shrinkage and selection operator algorithm was used to identify and verify the primary osteoporosis-related biomarkers. Immune cell correlation analysis, gene enrichment analysis and drug target network analysis were performed. Finally, the biomarkers were validated using qPCR assay.
RESULTS AND CONCLUSION: A total of 126 differentially expressed genes and 5 biomarkers including prostaglandins, epidermal growth factor receptor, mitogen-activated protein kinase 3, transforming growth factor B1, and retinoblastoma gene 1 were obtained in this study. GO analysis showed that differentially expressed genes were mainly concentrated in the cellular response to oxidative stress and the regulation of autophagy. KEGG analysis showed that autophagy and senescence pathways were mainly involved. Immunoassay of biomarkers showed that prostaglandins, retinoblastoma gene 1, and mitogen-activated protein kinase 3 were closely related to immune cells. Gene enrichment analysis showed that biomarkers were associated with immune-related pathways. Drug target network analysis showed that the five biomarkers were associated with primary osteoporosis drugs. The results of qPCR showed that the expression of prostaglandins, epidermal growth factor receptor, mitogen-activated protein kinase 3, and transforming growth factor B1 in the primary osteoporosis sample was significantly increased compared with the control sample (P < 0.001), while the expression of retinoblastoma gene 1 in the primary osteoporosis sample was significantly decreased compared with the control sample (P < 0.001). Overall, the study screened and validated five potential biomarkers of primary osteoporosis, providing a reference basis for further in-depth investigation of the pathogenesis, early screening and diagnosis, and targeted treatment of primary osteoporosis.
