siRNA knockdown of EZH2 promotes expression of ZBTB16, MX1, and FHL1 in OB. MSC were treated with negative control siRNA, EZH2 siRNA #1, and EZH2 siRNA #2. MSC were cultured for 14 days with osteogenic differentiation media. (A) Knockdown of EZH2 by siRNA was confirmed by RT-PCR. (B) RT-PCR reveals a significant increase in RUNX2 expression compared with negative control-treated OB. (C)
ZBTB16, MX1, and FHL1 gene expression was upregulated in EZH2 siRNA-treated OB compared with negative control-treated OB. Mean values ± SEM, n = 3 independent MSC donors (*P < 0.05, 1-way ANOVA with Dunnett's multiple comparison test).
