Biomechanical stimulation of osteoblast gene expression requires phosphorylation of the RUNX2 transcription factor

Abstract excerpt

Bone can adapt its structure in response to mechanical stimuli. At the cellular level, this involves changes in chromatin organization, gene expression, and differentiation, but the underlying mechanisms are poorly understood. Here we report on the involvement of RUNX2, a bone-related transcription factor, in this process. Fluid flow shear stress loading of preosteoblasts stimulated translocation of extracellular...
