a, b The hUC-MSCs were cultured in normal growth medium (Undiff) or in osteogenic differentiation medium (Diff) for 10 days. The antibodies H2AK119ub, H2BK120ub, H3K4me3, and IgG were incubated with cell lysates, respectively, and the enrichment of those three histone markers on OSX or RUNX2 promoter was analyzed by ChIP-qPCR. c, d The hUC-MSCs were transfected with NC and ODIR1 siRNAs. The antibodies H2AK119ub, H2BK120ub, H3K4me3, and IgG were incubated with cell lysates, respectively, and the enrichment of those three histone markers on OSX or RUNX2 was analyzed by ChIP-qPCR. e The pMIR-OSX-luc (containing OSX promoter region) or pMIR-RUNX2-luc (containing RUNX2 promoter region) plasmids were co-transfected with pCDH-ODIR1 or pCDH plasmids into 293 cells, respectively, and the cell lysates were analyzed by luciferase assay. f The pMIR-OSX-luc plasmid was co-transfected with NC and ODIR1 siRNAs into 293 cells, respectively, and the cell lysates were analyzed by luciferase assay. g The pMIR-OSX-luc plasmids were co-transfected with different amounts (0.1, 0.2, 0.5, 1.0 μg) of pCDH-ODIR1 plasmids into 293 cells, respectively, and analyzed by luciferase assay.
