Fig. 6From: DNMT and HDAC inhibitors modulate MMP-9-dependent H3 N-terminal tail proteolysis and osteoclastogenesisEffects of TSA and 5-Aza-CdR co-treatment on osteoclastogenesis. a OCP-induced cells were treated with the combination of 5-Aza-CdR and TSA (lower panel) or DMSO control (upper panel) for 0, 1, 3 and 5 days and stained for TRAP. b OCP-induced cells were treated as in a, and changes in MMP-9 expression were analyzed by RT-qPCR (left panel) and Western blot (right panel). Chromatin was also isolated and analyzed by Western blotting to assess the effects of the combined treatment on H3NT proteolysis (right panel)Back to article page
