(A) qRT-PCR of EZH2, JMJD3, and RUNX2 following differentiation of hMSCs treated with either JMJD3 inhibitor GSK-J4 or 0.02% DMSO. The fold change in transcript levels following GSK-J4 treatment is shown relative to vehicle treatment. (B) Promoter regions of SP7, RUNX2, BMP2, and GAPDH were examined by ChIP using either anti-H3K27me3 antibody or anti-IgG control antibody. Enrichment is presented as percent of chromatin input. All graphs exhibit the mean value ± SEM of 3 biological replicates. *P<0.05, **P<0.01, ***P<0.001; statistical differences were calculated by Student’s t test.
