has-miR-100-5p 靶向含7A 的锌指和BTB 结构域是绝经后骨质疏松的潜在靶标.

BACKGROUND: miRNAs play an important role in the pathogenesis of osteoporosis, which therefore can be important therapeutic targets. Among them, targeting the miR-100-5p regulatory axis to promote osteoblast differentiation is a potential therapeutic target for osteoporosis. OBJECTIVE: To explore the targeted regulatory roles of has-miR-100-5p and has-miR-101-3p in postmenopausal osteoporosis. METHODS: Differentially expressed genes between high and low bone mineral density in the GSE56814 and GSE56815 datasets were identified and subjected to enrichment analyses. Target genes of has-miR-100-5p and has-miR-101-3p among the differentially expressed genes were predicted. Peripheral blood samples from 40 patients with postmenopausal osteoporosis and 40 healthy controls were selected and qRT-PCR experiments were performed to detect the differential expression of has-miR-100-5p and has-miR-101-3p as well as target genes. Dual luciferase reporter assay was used to measure the targeting effect of miRNAs to the 3'UTR of target genes. RESULTS AND CONCLUSION: A total of 81 common differentially expressed genes were identified between high and low bone mineral density, mainly significantly enriched in immunity, nuclear factor-κB compound, and tumor necrosis factor signaling pathway. Has-miR-100-5p and has-miR-101-3p were targeted to regulate zinc finger and BTB domain containing 7A (ZBTB7A) based on miRTargetbase database and miRTarget database predictions. Has-miR-100- 5p was up-regulated (P < 0.001) and has-miR-101-3p and ZBTB7A were down-regulated (P < 0.001) in postmenopausal osteoporosis patients compared with the healthy controls. The fluorescence activity of 293T cells was down-regulated after co-transfection of has-miR-100-5p with wild-type ZBTB7A-3’UTR. To conclude, has-miR-100-5p targeting ZBTB7A may be a potential target for postmenopausal osteoporosis. [ABSTRACT FROM AUTHOR]
