Transforming Growth Factor-β Inhibits Pulmonary Surfactant Protein B Gene Transcription through SMAD3 Interactions with NKX2.1 and HNF-3 Transcription Factors
1 Oct 2002
Abstract excerpt
Transforming growth factor-beta (TGF-beta) represses surfactant protein B (Sp-B) gene transcription through a mechanism that remains unknown. A homeodomain and a forkhead transcription factor, NKX2.1 and HNF-3, respectively, are known activators of Sp-B transcription. Because SMADs are the effectors of TGF-beta-induced gene activation, we examined the possibility that gene repression by TGF-beta may also occur...
