c-Myc is one of the most potent regulators of cell cycle progression in higher eukaryotes. Down-regulation of c-Myc is a critical event for growth inhibition induced by transforming growth factor-beta (TGF-beta) and is frequently impaired in cancer cells. We determined a Smad-responsive element in the c-myc promoter. This element is a complex of the TGF-beta1 inhibitory element (TIE) originally identified in the transin/stromelysin promoter and an E2F site responsible for transcriptional… CONTINUE READING
