    NF-AT-Driven interleukin-4 transcription potentiated by NIP45 (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-12-13
    Description: The induction of cytokine gene transcription is mediated in part by the nuclear factor of activated T cells (NF-AT). Factors involved in the mechanisms of NF-AT-mediated transcription are not well understood. A nuclear factor that interacted with the Rel homology domain (RHD) of NF-ATp was identified with the use of a two-hybrid interaction trap. Designated NIP45 (NF-AT interacting protein), it has minimal similarity to any known genes. Transcripts encoding this factor were enriched in lymphoid tissues and testes. NIP45 synergized with NF-ATp and the proto-oncogene c-Maf to activate the interleukin-4 (IL-4) cytokine promoter; transient overexpression of NIP45 with NF-ATp and c-maf in B lymphoma cells induced measurable endogenous IL-4 protein production. The identification of NIP45 advances our understanding of gene activation of cytokines, critical mediators of the immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodge, M R -- Chun, H J -- Rengarajan, J -- Alt, A -- Lieberson, R -- Glimcher, L H -- AI37833/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1996 Dec 13;274(5294):1903-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology, Harvard School of Public Health and Department of Medicine, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8943202" target="_blank"〉PubMed〈/a〉

    Rational design of potent, bioavailable, nonpeptide cyclic ureas as HIV protease inhibitors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-21
    Description: Mechanistic information and structure-based design methods have been used to design a series of nonpeptide cyclic ureas that are potent inhibitors of human immunodeficiency virus (HIV) protease and HIV replication. A fundamental feature of these inhibitors is the cyclic urea carbonyl oxygen that mimics the hydrogen-bonding features of a key structural water molecule. The success of the design in both displacing and mimicking the structural water molecule was confirmed by x-ray crystallographic studies. Highly selective, preorganized inhibitors with relatively low molecular weight and high oral bioavailability were synthesized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, P Y -- Jadhav, P K -- Eyermann, C J -- Hodge, C N -- Ru, Y -- Bacheler, L T -- Meek, J L -- Otto, M J -- Rayner, M M -- Wong, Y N -- New York, N.Y. -- Science. 1994 Jan 21;263(5145):380-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology Research, DuPont Merck Pharmaceutical Company, Wilmington, DE 19880.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8278812" target="_blank"〉PubMed〈/a〉
