Impaired cell cycle regulation of the osteoblast-related heterodimeric transcription factor Runx2-Cbfbeta in osteosarcoma cells.

29 Nov 2009 Bone formation and osteoblast differentiation require the functional expression of the Runx2/Cbfbeta heterodimeric transcription factor complex. Runx2 is also a suppressor of proliferation in osteoblasts by attenuating cell cycle progression in ... Read more...

Osteoblast differentiation is functionally associated with decreased AMP kinase activity.

29 Nov 2009 Osteoblasts, originating from mesenchymal stem cells, play a pivotal role in bone formation and mineralization. Several transcription factors including runt-related transcription factor 2 (Runx2) have been reported to be essential for osteoblast ... Read more...

Effect of ibuprofen on osteoblast differentiation of porcine bone marrow-derived progenitor cells.

30 Oct 2009 PURPOSE: Nonsteroidal anti-inflammatory drugs are commonly prescribed to reduce inflammation and pain. However, little is known about the direct effect of these drugs on the differentiation of bone marrow-derived progenitor cells into osteoblasts. ... Read more...
