1 Activation of the second promoter of the transforming growth factor-beta 1 gene by transforming growth factor-beta 1 and phorbol ester occurs through the same target sequences. Phorbol Esters transforming growth factor beta 1 Homo sapiens
2 Two distinct regions of the transforming growth factor-beta 1 (TGF-beta 1) promoter are responsive to autoregulation and activation by phorbol ester (12-O-tetradecanoylphorbol-13-acetate): sequences located between nucleotides -454 to -323 (first promoter) and between the two transcriptional start sites. Phorbol Esters transforming growth factor beta 1 Homo sapiens
3 Two distinct regions of the transforming growth factor-beta 1 (TGF-beta 1) promoter are responsive to autoregulation and activation by phorbol ester (12-O-tetradecanoylphorbol-13-acetate): sequences located between nucleotides -454 to -323 (first promoter) and between the two transcriptional start sites. Phorbol Esters transforming growth factor beta 1 Homo sapiens
4 We have now characterized in detail the induction of the second promoter (sequences between nucleotides + 1 to +271) of the TGF-beta 1 gene by both TGF-beta 1 and phorbol ester. Phorbol Esters transforming growth factor beta 1 Homo sapiens
5 These results suggest that AP-1, which is capable of conferring phorbol ester or TGF-beta 1 responsiveness, is the major transcription factor involved in the second promoter-derived transcription of the TGF-beta 1 gene. Phorbol Esters transforming growth factor beta 1 Homo sapiens
