Postmenopausal osteoporosis (PMO) is acknowledged as a principal category of osteoporosis (OP). The aim of this study was to investigate the level of miR-370-3p in PMO patients and its predictive effect on osteoporosis in postmenopausal women, and to explore the molecular mechanism of miR-370-3p on PMO.
The expression of miR-370-3p was assessed using RT-qPCR. Cell proliferation of MC3T3-E1 cells was evaluated through CCK-8 assays. Cell apoptosis was detected by flow cytometry. The direct interaction between miR-370-3p and INO80 was confirmed via dual-luciferase reporter assays.
The level of miR-370-3p was found to be upregulated in osteoporosis patients, and miR-370-3p played a significant role in regulating the proliferation, apoptosis and differentiation of osteoblasts. In addition, miR-370-3p targeted INO80 and affected the disease progression of PMO.
miR-370-3p/INO80 may serve as a promising biomarker for both the diagnosis and therapeutic management of PMO.
绝经后骨质疏松症(PMO)被认为是骨质疏松症(OP)的主要类型。本研究旨在调查PMO患者中miR-370-3p的水平及其对绝经后女性骨质疏松症的预测作用,并探讨miR-370-3p对PMO的分子机制。
采用RT-qPCR评估miR-370-3p的表达。通过CCK-8试验评估MC3T3-E1细胞的细胞增殖。通过流式细胞术检测细胞凋亡。通过双荧光素酶报告试验证实miR-370-3p与INO80之间的直接相互作用。
发现骨质疏松症患者中miR-370-3p水平上调,并且miR-370-3p在调节成骨细胞的增殖、凋亡和分化中起重要作用。此外,miR-370-3p靶向INO80并影响PMO的疾病进展。
miR-370-3p/INO80可能作为PMO诊断和治疗管理的有前景的生物标志物。
