    Identification of a nuclear receptor for bile acids (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-05-21
    Description: Bile acids are essential for the solubilization and transport of dietary lipids and are the major products of cholesterol catabolism. Results presented here show that bile acids are physiological ligands for the farnesoid X receptor (FXR), an orphan nuclear receptor. When bound to bile acids, FXR repressed transcription of the gene encoding cholesterol 7alpha-hydroxylase, which is the rate-limiting enzyme in bile acid synthesis, and activated the gene encoding intestinal bile acid-binding protein, which is a candidate bile acid transporter. These results demonstrate a mechanism by which bile acids transcriptionally regulate their biosynthesis and enterohepatic transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makishima, M -- Okamoto, A Y -- Repa, J J -- Tu, H -- Learned, R M -- Luk, A -- Hull, M V -- Lustig, K D -- Mangelsdorf, D J -- Shan, B -- New York, N.Y. -- Science. 1999 May 21;284(5418):1362-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75235-9050, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334992" target="_blank"〉PubMed〈/a〉

    Vitamin D receptor as an intestinal bile acid sensor (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-23
    Description: The vitamin D receptor (VDR) mediates the effects of the calcemic hormone 1alpha,25-dihydroxyvitamin D3 [1,25(OH)2D3]. We show that VDR also functions as a receptor for the secondary bile acid lithocholic acid (LCA), which is hepatotoxic and a potential enteric carcinogen. VDR is an order of magnitude more sensitive to LCA and its metabolites than are other nuclear receptors. Activation of VDR by LCA or vitamin D induced expression in vivo of CYP3A, a cytochrome P450 enzyme that detoxifies LCA in the liver and intestine. These studies offer a mechanism that may explain the proposed protective effects of vitamin D and its receptor against colon cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makishima, Makoto -- Lu, Timothy T -- Xie, Wen -- Whitfield, G Kerr -- Domoto, Hideharu -- Evans, Ronald M -- Haussler, Mark R -- Mangelsdorf, David J -- New York, N.Y. -- Science. 2002 May 17;296(5571):1313-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9050, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12016314" target="_blank"〉PubMed〈/a〉

    Visfatin: a protein secreted by visceral fat that mimics the effects of insulin (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Fat tissue produces a variety of secreted proteins (adipocytokines) with important roles in metabolism. We isolated a newly identified adipocytokine, visfatin, that is highly enriched in the visceral fat of both humans and mice and whose expression level in plasma increases during the development of obesity. Visfatin corresponds to a protein identified previously as pre-B cell colony-enhancing factor (PBEF), a 52-kilodalton cytokine expressed in lymphocytes. Visfatin exerted insulin-mimetic effects in cultured cells and lowered plasma glucose levels in mice. Mice heterozygous for a targeted mutation in the visfatin gene had modestly higher levels of plasma glucose relative to wild-type littermates. Surprisingly, visfatin binds to and activates the insulin receptor. Further study of visfatin's physiological role may lead to new insights into glucose homeostasis and/or new therapies for metabolic disorders such as diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fukuhara, Atsunori -- Matsuda, Morihiro -- Nishizawa, Masako -- Segawa, Katsumori -- Tanaka, Masaki -- Kishimoto, Kae -- Matsuki, Yasushi -- Murakami, Mirei -- Ichisaka, Tomoko -- Murakami, Hiroko -- Watanabe, Eijiro -- Takagi, Toshiyuki -- Akiyoshi, Megumi -- Ohtsubo, Tsuguteru -- Kihara, Shinji -- Yamashita, Shizuya -- Makishima, Makoto -- Funahashi, Tohru -- Yamanaka, Shinya -- Hiramatsu, Ryuji -- Matsuzawa, Yuji -- Shimomura, Iichiro -- New York, N.Y. -- Science. 2005 Jan 21;307(5708):426-30.

    Enhancement of activity of 1alpha, 25-dihydroxyvitamin D3 for growth inhibition and differentiation induction of human myelomonocytic leukemia cells by tretinoin tocoferil, an alpha-tocopherol ester of all- trans retinoic acid (1996)
    American Society of Hematology
    Details
    Publication Date: 1996-04-15
    Description: Tretinoin tocoferil is an alpha-tocopherol ester of all-trans retinoic acid (RA) and safely used in the treatment of skin ulcer. Tretinoin tocoferil inhibited proliferation of human promyelocytic leukemia HL-60 cells and induced granulocytic differentiation of the cells, but less than RA. alpha-Tocopherol did not affect differentiation of HL-60 cells, but at high concentrations enhanced its nitroblue tetrazolium (NBT)-reducing activity and expression of surface antigen CD11b, which are markers of myelomonocytic differentiation induced by RA. Tretinoin tocoferil increased NBT reduction in HL-60 cells treated with RA. It also enhanced the differentiation of HL-60 cells induced by dimethyl sulfoxide, phorbol-12-myristate 13-acetate or 1alpha,25- dihydroxyvitamin D3 (VD3). In combination with a low concentration of VD3, it induced the NBT-reducing activity of human monoblastic U937 cells very effectively. Moreover, it enhanced the differentiation of human myelomonocytic ML-1, THP-1, P39/TSU, and P31/FUJ cells induced by VD3. In combination with VD3, it synergistically inhibited the proliferation of HL-60, U937, ML-1, THP-1, P39/TSU, and P31/FUJ cells and decreased the effective concentration of VD3 to a 10(-10) mol/L level. Because tretinoin tocoferil was reported to induce neither retinoid-related toxicity nor teratogenicity, the therapeutic advantage of the use of it in treatment of myelomonocytic leukemia is suggested.
