Chromatin Immunoprecipitation (ChIP) assays of OVX and Sham mouse BMMSCs. (a) Dimethylation level of histone H3 at lysine 4 (H3K4) at the promoter region of Runx2 of Sham BMMSCs at 7 days after adding pargyline. (b) Dimethylation level of H3K4 at the promoter region of Runx2 of OVX BMMSCs at 7 days after adding pargyline. (c) Dimethylation level of H3K4 at the promoter region of OC of Sham BMMSCs at 7 days after adding pargyline. (d) Dimethylation level of H3K4 at the promoter region of OC of OVX BMMSCs at 7 days after adding pargyline. *P<0.05. n=6. OM, osteogenic medium; OP, OM with 1.5 mmol·L−1 pargyline; PM, proliferation medium; PP, PM with 1.5 mmol·L−1 pargyline.
