Silencing CircRNA124534 suppresses the osteogenic differentiation of DPSCs and overexpressing β-catenin reversed the inhibition. (A) The level of CircRNA124534 and β-catenin was determined by RT-PCR in DPSCs transfected with CircRNA124534 silencing vector (si-circ) or β-catenin overexpression vector (oe-β-catenin) for 48 h. (B) The level ofβ-catenin was determined by western blotting in DPSCs transfected with si-circ or oe-β-catenin for 48 h. (C,D) ARS mineralization assay on day 14 after osteogenic induction in PM or OM. Scale bars = 50 μm. (E,F) ALP activity on day 7 after osteogenic induction. Scale bars = 100 μm. (G,H) The levels of RUNX and OCN were determined by RT-PCR and western blotting in DPSCs on day 14 after osteogenic induction. Data indicate the mean ± SD, n = 3. **P < 0.01, ***P < 0.001 vs. control, ##P < 0.01, ###P < 0.001 vs. miR-496 inhibitor.
