    Description: Concentrations of plasma homovanillic acid before treatment were highly correlated with global severity of illness in schizophrenic patients, both before and after treatment. In contrast, a fixed dose of haloperidol did not affect those concentrations. Thus, in patients with a diagnosis of schizophrenia, plasma homovanillic acid may reflect the severity of illness, but not be influenced by short-term pharmacological perturbations by neuroleptics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, K L -- Davidson, M -- Mohs, R C -- Kendler, K S -- Davis, B M -- Johns, C A -- DeNigris, Y -- Horvath, T B -- MH37922/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 29;227(4694):1601-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3975630" target="_blank"〉PubMed〈/a〉

    Description: Analysis of the 1,042,519-base pair Chlamydia trachomatis genome revealed unexpected features related to the complex biology of chlamydiae. Although chlamydiae lack many biosynthetic capabilities, they retain functions for performing key steps and interconversions of metabolites obtained from their mammalian host cells. Numerous potential virulence-associated proteins also were characterized. Several eukaryotic chromatin-associated domain proteins were identified, suggesting a eukaryotic-like mechanism for chlamydial nucleoid condensation and decondensation. The phylogenetic mosaic of chlamydial genes, including a large number of genes with phylogenetic origins from eukaryotes, implies a complex evolution for adaptation to obligate intracellular parasitism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, R S -- Kalman, S -- Lammel, C -- Fan, J -- Marathe, R -- Aravind, L -- Mitchell, W -- Olinger, L -- Tatusov, R L -- Zhao, Q -- Koonin, E V -- Davis, R W -- AI 39258/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1998 Oct 23;282(5389):754-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Infectious Diseases, University of California, Berkeley, CA 94720, USA. ctgenome@socrates.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9784136" target="_blank"〉PubMed〈/a〉

    Description: In many organisms, master control genes coordinately regulate sex-specific aspects of development. SDC-2 was shown to induce hermaphrodite sexual differentiation and activate X chromosome dosage compensation in Caenorhabditis elegans. To control these distinct processes, SDC-2 acts as a strong gene-specific repressor and a weaker chromosome-wide repressor. To initiate hermaphrodite development, SDC-2 associates with the promoter of the male sex-determining gene her-1 to repress its transcription. To activate dosage compensation, SDC-2 triggers assembly of a specialized protein complex exclusively on hermaphrodite X chromosomes to reduce gene expression by half. SDC-2 can localize to X chromosomes without other components of the dosage compensation complex, suggesting that SDC-2 targets dosage compensation machinery to X chromosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawes, H E -- Berlin, D S -- Lapidus, D M -- Nusbaum, C -- Davis, T L -- Meyer, B J -- GM30702/GM/NIGMS NIH HHS/ -- T32 GM07127/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jun 11;284(5421):1800-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720-3204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10364546" target="_blank"〉PubMed〈/a〉

    Description: The nuclear factor of activated T cells (NFAT) group of transcription factors is retained in the cytoplasm of quiescent cells. NFAT activation is mediated in part by induced nuclear import. This process requires calcium-dependent dephosphorylation of NFAT caused by the phosphatase calcineurin. The c-Jun amino-terminal kinase (JNK) phosphorylates NFAT4 on two sites. Mutational removal of the JNK phosphorylation sites caused constitutive nuclear localization of NFAT4. In contrast, JNK activation in calcineurin-stimulated cells caused nuclear exclusion of NFAT4. These findings show that the nuclear accumulation of NFAT4 promoted by calcineurin is opposed by the JNK signal transduction pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chow, C W -- Rincon, M -- Cavanagh, J -- Dickens, M -- Davis, R J -- CA58396/CA/NCI NIH HHS/ -- CA65831/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1638-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Program in Molecular Medicine, Department of Biochemistry and Molecular Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374467" target="_blank"〉PubMed〈/a〉

    Description: Angiogenesis is thought to depend on a precise balance of positive and negative regulation. Angiopoietin-1 (Ang1) is an angiogenic factor that signals through the endothelial cell-specific Tie2 receptor tyrosine kinase. Like vascular endothelial growth factor, Ang1 is essential for normal vascular development in the mouse. An Ang1 relative, termed angiopoietin-2 (Ang2), was identified by homology screening and shown to be a naturally occurring antagonist for Ang1 and Tie2. Transgenic overexpression of Ang2 disrupts blood vessel formation in the mouse embryo. In adult mice and humans, Ang2 is expressed only at sites of vascular remodeling. Natural antagonists for vertebrate receptor tyrosine kinases are atypical; thus, the discovery of a negative regulator acting on Tie2 emphasizes the need for exquisite regulation of this angiogenic receptor system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maisonpierre, P C -- Suri, C -- Jones, P F -- Bartunkova, S -- Wiegand, S J -- Radziejewski, C -- Compton, D -- McClain, J -- Aldrich, T H -- Papadopoulos, N -- Daly, T J -- Davis, S -- Sato, T N -- Yancopoulos, G D -- New York, N.Y. -- Science. 1997 Jul 4;277(5322):55-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals Inc., 777 Old Saw Mill River Road, Tarrytown, NY 10591, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9204896" target="_blank"〉PubMed〈/a〉

    Description: Two families of small peptides that bind to the human thrombopoietin receptor and compete with the binding of the natural ligand thrombopoietin (TPO) were identified from recombinant peptide libraries. The sequences of these peptides were not found in the primary sequence of TPO. Screening libraries of variants of one of these families under affinity-selective conditions yielded a 14-amino acid peptide (Ile-Glu-Gly-Pro-Thr-Leu-Arg-Gln-Trp-Leu-Ala-Ala-Arg-Ala) with high affinity (dissociation constant approximately 2 nanomolar) that stimulates the proliferation of a TPO-responsive Ba/F3 cell line with a median effective concentration (EC50) of 400 nanomolar. Dimerization of this peptide by a carboxyl-terminal linkage to a lysine branch produced a compound with an EC50 of 100 picomolar, which was equipotent to the 332-amino acid natural cytokine in cell-based assays. The peptide dimer also stimulated the in vitro proliferation and maturation of megakaryocytes from human bone marrow cells and promoted an increase in platelet count when administered to normal mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cwirla, S E -- Balasubramanian, P -- Duffin, D J -- Wagstrom, C R -- Gates, C M -- Singer, S C -- Davis, A M -- Tansik, R L -- Mattheakis, L C -- Boytos, C M -- Schatz, P J -- Baccanari, D P -- Wrighton, N C -- Barrett, R W -- Dower, W J -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1696-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Affymax Research Institute, 4001 Miranda Avenue, Palo Alto, CA 94304, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180079" target="_blank"〉PubMed〈/a〉

    Description: Unequal crossing-over within a head-to-tail tandem array of the homologous red and green visual pigment genes has been proposed to explain the observed variation in green-pigment gene number among individuals and the prevalence of red-green fusion genes among color-blind subjects. This model was tested by probing the structure of the red and green pigment loci with long-range physical mapping techniques. The loci were found to constitute a gene array with an approximately 39-kilobase repeat length. The position of the red pigment gene at the 5' edge of the array explains its lack of variation in copy number. Restriction maps of the array in four individuals who differ in gene number are consistent with a head-to-tail configuration of the genes. These results provide physical evidence in support of the model and help to explain the high incidence of color blindness in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vollrath, D -- Nathans, J -- Davis, R W -- GM21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 17;240(4859):1669-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2837827" target="_blank"〉PubMed〈/a〉

    Description: In the polymerase chain reaction (PCR), two specific oligonucleotide primers are used to amplify the sequences between them. However, this technique is not suitable for amplifying genes that encode molecules where the 5' portion of the sequences of interest is not known, such as the T cell receptor (TCR) or immunoglobulins. Because of this limitation, a novel technique, anchored polymerase chain reaction (A-PCR), was devised that requires sequence specificity only on the 3' end of the target fragment. It was used to analyze TCR delta chain mRNA's from human peripheral blood gamma delta T cells. Most of these cells had a V delta gene segment not previously described (V delta 3), and the delta chain junctional sequences formed a discrete subpopulation compared with those previously reported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loh, E Y -- Elliott, J F -- Cwirla, S -- Lanier, L L -- Davis, M M -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):217-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Medicine and Microbiology and Immunology, Stanford University School of Medicine, CA 94305-5402.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2463672" target="_blank"〉PubMed〈/a〉

    Description: BAX is a pro-apoptotic protein of the BCL-2 family that is stationed in the cytosol until activated by a diversity of stress stimuli to induce cell death. Anti-apoptotic proteins such as BCL-2 counteract BAX-mediated cell death. Although an interaction site that confers survival functionality has been defined for anti-apoptotic proteins, an activation site has not been identified for BAX, rendering its explicit trigger mechanism unknown. We previously developed stabilized alpha-helix of BCL-2 domains (SAHBs) that directly initiate BAX-mediated mitochondrial apoptosis. Here we demonstrate by NMR analysis that BIM SAHB binds BAX at an interaction site that is distinct from the canonical binding groove characterized for anti-apoptotic proteins. The specificity of the human BIM-SAHB-BAX interaction is highlighted by point mutagenesis that disrupts functional activity, confirming that BAX activation is initiated at this novel structural location. Thus, we have now defined a BAX interaction site for direct activation, establishing a new target for therapeutic modulation of apoptosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2597110/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2597110/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gavathiotis, Evripidis -- Suzuki, Motoshi -- Davis, Marguerite L -- Pitter, Kenneth -- Bird, Gregory H -- Katz, Samuel G -- Tu, Ho-Chou -- Kim, Hyungjin -- Cheng, Emily H-Y -- Tjandra, Nico -- Walensky, Loren D -- 5P01CA92625/CA/NCI NIH HHS/ -- 5R01CA125562/CA/NCI NIH HHS/ -- 5R01CA50239/CA/NCI NIH HHS/ -- K99 HL095929/HL/NHLBI NIH HHS/ -- K99 HL095929-01A1/HL/NHLBI NIH HHS/ -- K99 HL095929-02/HL/NHLBI NIH HHS/ -- R00 HL095929/HL/NHLBI NIH HHS/ -- R01 CA050239/CA/NCI NIH HHS/ -- R01 CA125562/CA/NCI NIH HHS/ -- R01 CA125562-02/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1076-81. doi: 10.1038/nature07396.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatric Oncology and the Program in Cancer Chemical Biology, Dana-Farber Cancer Institute, 44 Binney Street, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948948" target="_blank"〉PubMed〈/a〉
