Osteoporosis (OP) is a disease characterized by bone loss, imbalance of bone metabolism and destruction of trabecular microstructure, and associated with menopause. Studies have shown that immune related lymphocytes are involved in bone metabolism. However, the molecular mechanisms hidden in the interaction of lymphocytes with OP need to be further studied. In the present study, we investigated the expression profiles and differences of lncRNAs, mRNAs, circRNAs and miRNAs in peripheral blood lymphocytes of patients with postmenopausal OP using Illumina-based complementary DNA (cDNA) deep sequencing (RNA-seq). 70 lncRNAs, 475 mRNAs, 260 circRNAs and 13 miRNAs were differentially expressed in patients with postmenopausal osteoporosis (OP group) compared with healthy controls (NC group). The functions of differentially expressed lncRNAs, circRNA, miRNA and potential targeting genes were predicted by Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Complex lncRNA-miRNA-mRNA and circRNA-miRNA-mRNA regulatory networks were constructed based on differentially expressed RNAs. Taken together, our study indicated that lncRNAs, mRNA, circRNAs and miRNA could associate with the occurrence of postmenopausal OP and may be as possible biomarkers and target genes in lymphocytes for OP.
骨质疏松症(OP)是一种以骨质流失、骨代谢失衡和小梁微结构破坏为特征,并与绝经相关的疾病。研究表明,免疫相关淋巴细胞参与骨代谢。然而,淋巴细胞与OP相互作用中隐藏的分子机制有待进一步研究。在本研究中,我们使用基于Illumina的互补DNA(cDNA)深度测序(RNA测序)研究绝经后OP患者外周血淋巴细胞中lncRNA、mRNA、circRNA和miRNA的表达谱及差异。与健康对照(NC组)相比,绝经后骨质疏松症患者(OP组)中有70种lncRNA、475种mRNA、260种circRNA和13种miRNA差异表达。通过基因本体论(GO)和京都基因与基因组百科全书(KEGG)分析预测差异表达的lncRNA、circRNA、miRNA及其潜在靶向基因的功能。基于差异表达的RNA构建了复杂的lncRNA-miRNA-mRNA和circRNA-miRNA-mRNA调控网络。综上所述,我们的研究表明lncRNA、mRNA、circRNA和miRNA可能与绝经后OP的发生有关,并且可能作为OP淋巴细胞中的潜在生物标志物和靶基因。
