Mechanism of o-aminophenol metabolism in human erythrocytes.

abstract：:Early B-cell factor 1 (Ebf1) is a transcription factor whose inactivation in all cells results in high bone mass because of an increase in bone formation. This observation suggests Ebf1 may be an inhibitor of osteoblast differentiation. To test this contention, we analyzed Ebf1 pattern of expression and function in os...
