    Molecular cloning of complementary DNA encoding the avian receptor for vitamin D (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-03-06
    Description: Vitamin D3 receptors are intracellular proteins that mediate the nuclear action of the active metabolite 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]. Two receptor-specific monoclonal antibodies were used to recover the complementary DNA (cDNA) of this regulatory protein from a chicken intestinal lambda gt11 cDNA expression library. The amino acid sequences that were deduced from this cDNA revealed a highly conserved cysteine-rich region that displayed homology with a domain characteristic of other steroid receptors and with the gag-erbA oncogene product of avian erythroblastosis virus. RNA selected via hybridization with this DNA sequence directed the cell-free synthesis of immunoprecipitable vitamin D3 receptor. Northern blot analysis of polyadenylated RNA with these cDNA probes revealed two vitamin D receptor messenger RNAs (mRNAs) of 2.6 and 3.2 kilobases in receptor-containing chicken tissues and a major cross-hybridizing receptor mRNA species of 4.2 kilobases in mouse 3T6 fibroblasts. The 4.2-kilobase species was substantially increased by prior exposure of 3T6 cells to 1,25(OH)2D3. This cDNA represents perhaps the rarest mRNA cloned to date in eukaryotes, as well as the first receptor sequence described for an authentic vitamin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDonnell, D P -- Mangelsdorf, D J -- Pike, J W -- Haussler, M R -- O'Malley, B W -- New York, N.Y. -- Science. 1987 Mar 6;235(4793):1214-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3029866" target="_blank"〉PubMed〈/a〉

    Point mutations in the human vitamin D receptor gene associated with hypocalcemic rickets (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-23
    Description: Hypocalcemic vitamin D-resistant rickets is a human genetic disease resulting from target organ resistance to the action of 1,25-dihydroxyvitamin D3. Two families with affected children homozygous for this autosomal recessive disorder were studied for abnormalities in the intracellular vitamin D receptor (VDR) and its gene. Although the receptor displays normal binding of 1,25-dihydroxyvitamin D3 hormone, VDR from affected family members has a decreased affinity for DNA. Genomic DNA isolated from these families was subjected to oligonucleotide-primed DNA amplification, and each of the nine exons encoding the receptor protein was sequenced for a genetic mutation. In each family, a different single nucleotide mutation was found in the DNA binding domain of the protein; one family near the tip of the first zinc finger (Gly----Asp) and one at the tip of the second zinc finger (Arg----Gly). The mutant residues were created in vitro by oligonucleotide directed point mutagenesis of wild-type VDR complementary DNA and this cDNA was transfected into COS-1 cells. The produced protein is biochemically indistinguishable from the receptor isolated from patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughes, M R -- Malloy, P J -- Kieback, D G -- Kesterson, R A -- Pike, J W -- Feldman, D -- O'Malley, B W -- New York, N.Y. -- Science. 1988 Dec 23;242(4886):1702-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2849209" target="_blank"〉PubMed〈/a〉

    Estrogen binding, receptor mRNA, and biologic response in osteoblast-like osteosarcoma cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-01
    Description: High specific activity estradiol labeled with iodine-125 was used to detect approximately 200 saturable, high-affinity (dissociation constant approximately equal to 1.0 nM) nuclear binding sites in rat (ROS 17/2.8) and human (HOS TE85) clonal osteoblast-like osteosarcoma cells. Of the steroids tested, only testosterone exhibited significant cross-reactivity with estrogen binding. RNA blot analysis with a complementary DNA probe to the human estrogen receptor revealed putative receptor transcripts of 6 to 6.2 kilobases in both rat and human osteosarcoma cells. Type I procollagen and transforming growth factor-beta messenger RNA levels were enhanced in cultured human osteoblast-like cells treated with 1 nM estradiol. Thus, estrogen can act directly on osteoblasts by a receptor-mediated mechanism and thereby modulate the extracellular matrix and other proteins involved in the maintenance of skeletal mineralization and remodeling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Komm, B S -- Terpening, C M -- Benz, D J -- Graeme, K A -- Gallegos, A -- Korc, M -- Greene, G L -- O'Malley, B W -- Haussler, M R -- New York, N.Y. -- Science. 1988 Jul 1;241(4861):81-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Arizona College of Medicine, Tucson 85724.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3164526" target="_blank"〉PubMed〈/a〉

    Molecular cloning of the chicken progesterone receptor (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-15
    Description: To define the functional domains of the progesterone receptor required for gene regulation, complementary DNA (cDNA) clones encoding the chicken progesterone receptor have been isolated from a chicken oviduct lambda gt11 cDNA expression library. Positive clones expressed antigenic determinants that cross-reacted with six monospecific antibodies derived from two independent sources. A 36-amino acid peptide sequence obtained by microsequencing of purified progesterone receptor was encoded by nucleotide sequences in the longest cDNA clone. Analysis of the amino acid sequence of the progesterone receptor deduced from the cDNA clones revealed a cysteine-rich region that was homologous to a region found in the estrogen and glucocorticoid receptors and to the avian erythroblastosis virus gag-erb-A fusion protein. Northern blot analysis with chicken progesterone receptor cDNA's indicated the existence of at least three messenger RNA species. These messages were found only in oviduct and could be induced by estrogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conneely, O M -- Sullivan, W P -- Toft, D O -- Birnbaumer, M -- Cook, R G -- Maxwell, B L -- Zarucki-Schulz, T -- Greene, G L -- Schrader, W T -- O'Malley, B W -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):767-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2426779" target="_blank"〉PubMed〈/a〉
