Post-translational modifications of histone N-terminal tail domains affect the local chromatin conformation and serve as a dynamic regulatory layer for controlling gene transcription during cell differentiation. However, the role of epigenetic modifications in the regulation of osteoblast differentiation is still not fully understood. Recently, we identified RCOR2 as a novel regulator of osteoblast differentiation in a genome-wide transcription profiling of mouse MC3T3-E1 cell...

Epigenetic mechanisms regulating osteoblast differentiation are still inadequately described. In a genome wide transcriptional profiling of MC3T3-E1 osteoblastic cell line, we identified RCOR2 as a significantly upregulated gene during a differentiation time-course from proliferative to mature osteoblasts. Similar expression profile of RCOR2 was found in mouse calvarial osteoblasts. RCOR2 belongs to CoREST/RCOR family of proteins that regulate action of lysine-specific histone...
