Webb28 juni 2024 · Chen et al. (2002) defined how, in the same context, SMAD3 can mediate transcriptional repression of the growth-promoting gene MYC (190080). A complex containing SMAD3, the transcription factors E2F4 (600659), E2F5 (600967), and DP1 (189902), and the corepressor p107 (116957) preexists in the cytoplasm. Webb4 apr. 2024 · both Smad3 and SREBP-1a activation cooperatively regulate TGFbeta transcriptional responses. Angiotensin II-induced activation of SREBP-1 required signaling through the angiotensin II type I receptor and activation of PI3K/Akt in addition to the chaperone SCAP and protease S1P.
