Abstract:
Objective:To investigate the clinical significance and regulatory molecular mechanism of the circular RNA(circRNA)hsa_circ_0001445 in postmenopausal osteoporosis(PMOP).Methods:RNA was extracted from clinically collected blood samples, and the expression of circRNA hsa_circ_0001445 was detected by quantitative real-time PCR(qRT-PCR). Luciferase reporter gene analysis and RNA pull-down experiments were performed to investigate the interaction between two genes.Results:Compared with healthy controls, the plasma circRNA hsa_circ_0001445 in PMOP patients was down regulated( P<0.001). The circRNA hsa_circ_0001445 distinguished PMOP patients from healthy controls with high sensitivity and specificity.The area under the ROC curve(AUC)was 0.9654(95% CI: 0.9361-0.9947, P<0.001), and the sensitivity was 94.0%, while the specificity was 88.0%.The circRNA hsa_circ_0001445 promoted the osteogenic differentiation and inhibited the adipogenic differentiation of hBMSCs.The circRNA hsa_circ_0001445 can directly bind to miR-127-5p. Conclusions:Plasma level of the circRNA hsa_circ_0001445 is a potential diagnostic biomarker of PMOP and regulates the balance between osteogenesis and adipogenesis in hBMSCs by sponging miR-127-5p.
