Progress in Cbf?1 gene and its regulation / 中国药理学通报

ABSTRACT

Cbf?1 gene encodes an osteoblast specific transcription factor that regulates osteoblast differentiation and bone formation. The Cbf?1 gene contains 9 exons, however, the alternative splicing of its exons leads to genesis of multiple Cbf?1 isoforms with differences in transactivation potentials. Several signal transduction pathways, such as Ras MAPK pathway, cAMP pathway, or Smads DPC4 pathway, are involved in regulating Cbf?1 activity or its expression. These studies open new doors in pharmacological control of bone formation and gene or cell therapy of slowing the progression of osteoporosis.
