Fig. 6: MiR-181a accelerated the osteoclastogenesis in vitro.

A TRAP staining was carried out to explore the function of miR-181a during the osteoclastogenesis. B Quantitative analysis was established. C BMMs were transfected with NC inhibitor and miR-181a inhibitor. DUSP6 expression was silenced using RNAi. TRAP staining were carried out to evaluate the osteoclast differentiation in the indicated groups. Original scale bars: 200 μm. D Quantitative analysis were carried out to confirm the TRAP staining analysis. E The effect of miR-181a on osteoclast apoptosis was calculated using Annexin V-FITC/PI kit by a flow cytometer. F The expression of DUSP6 in the indicated groups was analyzed using real-time PCR in RNAKL-induced osteoclastogenesis. Data in all bar graphs are expressed as mean ± SD (n = 3). *P < 0.05, #P < 0.01.
