    Description: Cell proliferation and differentiation are regulated by growth regulatory factors such as transforming growth factor-beta (TGF-beta) and the liphophilic hormone vitamin D. TGF-beta causes activation of SMAD proteins acting as coactivators or transcription factors in the nucleus. Vitamin D controls transcription of target genes through the vitamin D receptor (VDR). Smad3, one of the SMAD proteins downstream in the TGF-beta signaling pathway, was found in mammalian cells to act as a coactivator specific for ligand-induced transactivation of VDR by forming a complex with a member of the steroid receptor coactivator-1 protein family in the nucleus. Thus, Smad3 may mediate cross-talk between vitamin D and TGF-beta signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yanagisawa, J -- Yanagi, Y -- Masuhiro, Y -- Suzawa, M -- Watanabe, M -- Kashiwagi, K -- Toriyabe, T -- Kawabata, M -- Miyazono, K -- Kato, S -- New York, N.Y. -- Science. 1999 Feb 26;283(5406):1317-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular and Cellular Biosciences, University of Tokyo, Yayoi, Bunkyo-ku, Tokyo 113-0032, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10037600" target="_blank"〉PubMed〈/a〉

    Description: The cytokines LIF (leukemia inhibitory factor) and BMP2 (bone morphogenetic protein-2) signal through different receptors and transcription factors, namely STATs (signal transducers and activators of transcription) and Smads. LIF and BMP2 were found to act in synergy on primary fetal neural progenitor cells to induce astrocytes. The transcriptional coactivator p300 interacts physically with STAT3 at its amino terminus in a cytokine stimulation-independent manner, and with Smad1 at its carboxyl terminus in a cytokine stimulation-dependent manner. The formation of a complex between STAT3 and Smad1, bridged by p300, is involved in the cooperative signaling of LIF and BMP2 and the subsequent induction of astrocytes from neural progenitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakashima, K -- Yanagisawa, M -- Arakawa, H -- Kimura, N -- Hisatsune, T -- Kawabata, M -- Miyazono, K -- Taga, T -- New York, N.Y. -- Science. 1999 Apr 16;284(5413):479-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Cell Biology, Cell Fate Modulation Research Unit, Medical Research Institute, Tokyo Medical and Dental University, Tokyo 101-0062, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10205054" target="_blank"〉PubMed〈/a〉
