    Description: Tumor necrosis factor-alpha (TNF-alpha) is an important mediator of insulin resistance in obesity and diabetes through its ability to decrease the tyrosine kinase activity of the insulin receptor (IR). Treatment of cultured murine adipocytes with TNF-alpha was shown to induce serine phosphorylation of insulin receptor substrate 1 (IRS-1) and convert IRS-1 into an inhibitor of the IR tyrosine kinase activity in vitro. Myeloid 32D cells, which lack endogenous IRS-1, were resistant to TNF-alpha-mediated inhibition of IR signaling, whereas transfected 32D cells that express IRS-1 were very sensitive to this effect of TNF-alpha. An inhibitory form of IRS-1 was observed in muscle and fat tissues from obese rats. These results indicate that TNF-alpha induces insulin resistance through an unexpected action of IRS-1 to attenuate insulin receptor signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hotamisligil, G S -- Peraldi, P -- Budavari, A -- Ellis, R -- White, M F -- Spiegelman, B M -- DK 42539/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1996 Feb 2;271(5249):665-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Biology, Dana-Farber Cancer Institute, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8571133" target="_blank"〉PubMed〈/a〉

    Description: A 13.1-kilodalton protein, cysteine-rich neurotrophic factor (CRNF), was purified from the mollusk Lymnaea stagnalis by use of a binding assay on the p75 neurotrophin receptor. CRNF bound to p75 with nanomolar affinity but was not similar in sequence to neurotrophins or any other known gene product. CRNF messenger RNA expression was highest in adult foot subepithelial cells; in the central nervous system, expression was regulated by lesion. The factor evoked neurite outgrowth and modulated calcium currents in pedal motor neurons. Thus, CRNF may be involved in target-derived trophic support for motor neurons and could represent the prototype of another family of p75 ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fainzilber, M -- Smit, A B -- Syed, N I -- Wildering, W C -- Hermann -- van der Schors, R C -- Jimenez, C -- Li, K W -- van Minnen, J -- Bulloch, A G -- Ibanez, C F -- Geraerts, W P -- New York, N.Y. -- Science. 1996 Nov 29;274(5292):1540-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Neurobiology, Department of Neuroscience, Karolinska Institute, Berzelius Laboratories Building, Doktorsringen 12A, S-17177 Stockholm, Sweden. michael@cajal.mbb.ki.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8929417" target="_blank"〉PubMed〈/a〉

    Description: Magnetic source imaging revealed that the cortical representation of the digits of the left hand of string players was larger than that in controls. The effect was smallest for the left thumb, and no such differences were observed for the representations of the right hand digits. The amount of cortical reorganization in the representation of the fingering digits was correlated with the age at which the person had begun to play. These results suggest that the representation of different parts of the body in the primary somatosensory cortex of humans depends on use and changes to conform to the current needs and experiences of the individual.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elbert, T -- Pantev, C -- Wienbruch, C -- Rockstroh, B -- Taub, E -- New York, N.Y. -- Science. 1995 Oct 13;270(5234):305-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Konstanz, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569982" target="_blank"〉PubMed〈/a〉

    Description: DCoH, the dimerization cofactor of hepatocyte nuclear factor-1, stimulates gene expression by associating with specific DNA binding proteins and also catalyzes the dehydration of the biopterin cofactor of phenylalanine hydroxylase. The x-ray crystal structure determined at 3 angstrom resolution reveals that DCoH forms a tetramer containing two saddle-shaped grooves that comprise likely macromolecule binding sites. Two equivalent enzyme active sites flank each saddle, suggesting that there is a spatial connection between the catalytic and binding activities. Structural similarities between the DCoH fold and nucleic acid-binding proteins argue that the saddle motif has evolved to bind diverse ligands or that DCoH unexpectedly may bind nucleic acids.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Endrizzi, J A -- Cronk, J D -- Wang, W -- Crabtree, G R -- Alber, T -- New York, N.Y. -- Science. 1995 Apr 28;268(5210):556-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720-3206, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7725101" target="_blank"〉PubMed〈/a〉

    Description: Apoptosis plays an important role during neuronal development, and defects in apoptosis may underlie various neurodegenerative disorders. To characterize molecular mechanisms that regulate neuronal apoptosis, the contributions to cell death of mitogen-activated protein (MAP) kinase family members, including ERK (extracellular signal-regulated kinase), JNK (c-JUN NH2-terminal protein kinase), and p38, were examined after withdrawal of nerve growth factor (NGF) from rat PC-12 pheochromocytoma cells. NGF withdrawal led to sustained activation of the JNK and p38 enzymes and inhibition of ERKs. The effects of dominant-interfering or constitutively activated forms of various components of the JNK-p38 and ERK signaling pathways demonstrated that activation of JNK and p38 and concurrent inhibition of ERK are critical for induction of apoptosis in these cells. Therefore, the dynamic balance between growth factor-activated ERK and stress-activated JNK-p38 pathways may be important in determining whether a cell survives or undergoes apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xia, Z -- Dickens, M -- Raingeaud, J -- Davis, R J -- Greenberg, M E -- CA43855/CA/NCI NIH HHS/ -- CA65861/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 24;270(5240):1326-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481820" target="_blank"〉PubMed〈/a〉

    Description: Human T cell lymphotropic virus I (HTLV-I) is the etiological agent for adult T cell leukemia and tropical spastic paraparesis (also termed HTLV-I-associated myelopathy). HTLV-I-infected peripheral blood T cells exhibit an initial phase of interleukin-2 (IL-2)-dependent growth; over time, by an unknown mechanism, the cells become IL-2-independent. Whereas the Jak kinases Jak1 and Jak3 and the signal transducer and activator of transcription proteins Stat3 and Stat5 are activated in normal T cells in response to IL-2, this signaling pathway was constitutively activated in HTLV-I-transformed cells. In HTLV-I-infected cord blood lymphocytes, the transition from IL-2-dependent to IL-2-independent growth correlated with the acquisition of a constitutively activated Jak-STAT pathway, which suggests that this pathway participates in HTLV-I-mediated T cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Migone, T S -- Lin, J X -- Cereseto, A -- Mulloy, J C -- O'Shea, J J -- Franchini, G -- Leonard, W J -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604283" target="_blank"〉PubMed〈/a〉

    Description: The control of calcium release from intracellular stores (the sarcoplasmic reticulum) in cardiac muscle was examined with the use of a confocal microscope and voltage clamp techniques. Depolarization evoked graded calcium release by altering the extent of spatial and temporal summation of elementary calcium release events called "calcium sparks." These evoked sparks were triggered by local L-type calcium channel currents in a stochastic manner, were similar at different potentials, and resembled spontaneous calcium sparks. Once triggered, the calcium release from the sarcoplasmic reticulum during a calcium spark was independent of the duration of the triggering calcium influx. These results were used to develop a unifying model for cardiac excitation-contraction coupling that explains the large (but paradoxically stable) amplification of the trigger calcium influx by a combination of digital and analog behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cannell, M B -- Cheng, H -- Lederer, W J -- HL25675/HL/NHLBI NIH HHS/ -- HL36974/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 May 19;268(5213):1045-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Clinical Pharmacology, St. George's Hospital Medical School, London, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754384" target="_blank"〉PubMed〈/a〉

    Description: Three archaeological sites at Katanda on the Upper Semliki River in the Western Rift Valley of Zaire have provided evidence for a well-developed bone industry in a Middle Stone Age context. Artifacts include both barbed and unbarbed points as well as a daggerlike object. Dating by both direct and indirect means indicate an age of approximately 90,000 years or older. Together with abundant fish (primarily catfish) remains, the bone technology indicates that a complex subsistence specialization had developed in Africa by this time. The level of behavioral competence required is consistent with that of upper Paleolithic Homo sapiens sapiens.

    Description: Nerve growth factor (NGF) induces both differentiation and survival of neurons by binding to the Trk receptor protein tyrosine kinase. Although Ras is required for differentiation, it was not required for NGF-mediated survival of rat pheochromocytoma PC-12 cells in serum-free medium. However, the ability of NGF to prevent apoptosis (programmed cell death) was inhibited by wortmannin or LY294002, two specific inhibitors of phosphatidylinositol (Pl)-3 kinase. Moreover, platelet-derived growth factor (PDGF) prevented apoptosis of PC-12 cells expressing the wild-type PDGF receptor, but not of cells expressing a mutant receptor that failed to activate Pl-3 kinase. Cell survival thus appears to be mediated by a Pl-3 kinase signaling pathway distinct from the pathway that mediates differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yao, R -- Cooper, G M -- R01 CA 18689/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 31;267(5206):2003-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Dana-Farber Cancer Institute, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7701324" target="_blank"〉PubMed〈/a〉

    Description: In the news article "Can risky mergers save hospital-based research?" by Wade Roush (19 May, p. 968), the statement that University Hospitals of Cleveland rose from 20th in the rankings of teaching hospitals funded by the National Institutes of Health (NIH) in 1991 to 12th at present was incorrect. In fact, it was Case Western Reserve University (CWRU), with which University Hospitals of Cleveland is affiliated, that received $69 million in NIH grants in 1993, making it the 20th largest recipient of such grants among medical centers; the university then received $97 million in 1994, raising its rank to 12th. About $15 million of the increase, or 53%, was attributable to CWRU's 1992 affiliation with Henry Ford Hospital in Detroit. Other hospitals affiliated with Case Western include MetroHealth Medical Center, Mount Sinai Medical Center, St. Luke's Medical Center, and Cleveland Veterans' Affairs Medical Center.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cardon, L R -- Smith, S D -- Fulker, D W -- Kimberling, W J -- Pennington, B F -- DeFries, J C -- New York, N.Y. -- Science. 1995 Jun 16;268(5217):1553.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7777847" target="_blank"〉PubMed〈/a〉

    Description: Furosemide, a chloride cotransport inhibitor, reversibly blocked synchronized burst discharges in hippocampal slices without reducing the pyramidal cell response to single electrical stimuli. Images of the intrinsic optical signal acquired during these slice experiments indicated that furosemide coincidentally blocked changes in extracellular space. In urethane-anesthetized rats, systemically injected furosemide blocked kainic acid-induced electrical discharges recorded from cortex. These results suggest that (i) neuronal synchronization involved in epileptiform activity can be dissociated from synaptic excitability; (ii) nonsynaptic mechanisms, possibly associated with furosemide-sensitive cell volume regulation, may be critical for synchronization of neuronal activity; and (iii) agents that affect extracellular volume may have clinical utility as antiepileptic drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hochman, D W -- Baraban, S C -- Owens, J W -- Schwartzkroin, P A -- NS07144/NS/NINDS NIH HHS/ -- NS15317/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Oct 6;270(5233):99-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurological Surgery, University of Washington, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569957" target="_blank"〉PubMed〈/a〉

    Description: Fas (also known as Apo1 and CD95) is a cell surface receptor involved in apoptotic cell death. Fas expression and function were analyzed in three children (including two siblings) with a lymphoproliferative syndrome, two of whom also had autoimmune disorders. A large deletion in the gene encoding Fas and no detectable cell surface expression characterized the most affected patient. Clinical manifestations in the two related patients were less severe: Fas-mediated apoptosis was impaired and a deletion within the intracytoplasmic domain was detected. These findings illustrate the crucial regulatory role of Fas and may provide a molecular basis for some autoimmune diseases in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rieux-Laucat, F -- Le Deist, F -- Hivroz, C -- Roberts, I A -- Debatin, K M -- Fischer, A -- de Villartay, J P -- New York, N.Y. -- Science. 1995 Jun 2;268(5215):1347-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale (INSERM) U 429, Hopital Necker-Enfants Malades, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7539157" target="_blank"〉PubMed〈/a〉

    Description: Telomeres are the protein-DNA structures at the ends of eukaryotic chromosomes. In yeast, and probably most other eukaryotes, telomeres are essential. They allow the cell to distinguish intact from broken chromosomes, protect chromosomes from degradation, and are substrates for novel replication mechanisms. Telomeres are usually replicated by telomerase, a telomere-specific reverse transcriptase, although telomerase-independent mechanisms of telomere maintenance exist. Telomere replication is both cell cycle- and developmentally regulated, and its control is likely to be complex. Because telomere loss causes the kinds of chromosomal changes associated with cancer and aging, an understanding of telomere biology has medical relevance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zakian, V A -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1601-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Princeton University, NJ 08544, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502069" target="_blank"〉PubMed〈/a〉

    Description: Analysis of differences between siblings (sib pair analysis) is a standard method of genetic linkage analysis for mapping quantitative trait loci, such as those contributing to hypertension and obesity, in humans. In traditional designs, pairs are selected at random or with one sib having an extreme trait value. The majority of such pairs provide little power to detect linkage; only pairs that are concordant for high values, low values, or extremely discordant pairs (for example, one in the top 10 percent and the other in the bottom 10 percent of the distribution) provide substantial power. Focus on discordant pairs can reduce the amount of genotyping necessary over conventional designs by 10- to 40-fold.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Risch, N -- Zhang, H -- HD30712/HD/NICHD NIH HHS/ -- HG00348/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 16;268(5217):1584-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Epidemiology and Public Health, Yale University School of Medicine, New Haven, CT 06520-8034, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7777857" target="_blank"〉PubMed〈/a〉

    Description: A fundamental question in signal transduction is how stimulation of a specific protein kinase leads to phosphorylation of particular protein substrates throughout the cell. Recent studies indicate that specific anchoring proteins located at various sites in the cell compartmentalize the kinases to their sites of action. Inhibitors of the interactions between kinases and their anchoring proteins inhibit the functions mediated by the kinases. These data indicate that the location of these anchoring proteins provides some of the specificity of the responses mediated by each kinase and suggest that inhibitors of the interaction between the kinases and their anchoring proteins may be useful as therapeutic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mochly-Rosen, D -- R01 HL-43380/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Apr 14;268(5208):247-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Pharmacology, School of Medicine, Stanford University, CA 94305-5332, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7716516" target="_blank"〉PubMed〈/a〉

    Description: Eukaryotic chromosomes are capped with repetitive telomere sequences that protect the ends from damage and rearrangements. Telomere repeats are synthesized by telomerase, a ribonucleic acid (RNA)-protein complex. Here, the cloning of the RNA component of human telomerase, termed hTR, is described. The template region of hTR encompasses 11 nucleotides (5'-CUAACCCUAAC) complementary to the human telomere sequence (TTAGGG)n. Germline tissues and tumor cell lines expressed more hTR than normal somatic cells and tissues, which have no detectable telomerase activity. Human cell lines that expressed hTR mutated in the template region generated the predicted mutant telomerase activity. HeLa cells transfected with an antisense hTR lost telomeric DNA and began to die after 23 to 26 doublings. Thus, human telomerase is a critical enzyme for the long-term proliferation of immortal tumor cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, J -- Funk, W D -- Wang, S S -- Weinrich, S L -- Avilion, A A -- Chiu, C P -- Adams, R R -- Chang, E -- Allsopp, R C -- Yu, J -- AG09383/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geron Corporation, Menlo Park, CA 94025, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7544491" target="_blank"〉PubMed〈/a〉

    Description: Fragile X syndrome is the result of the unstable expansion of a trinucleotide repeat in the 5'-untranslated region of the FMR1 gene. Fibroblast subclones from a mildly affected patient, each containing stable FMR1 alleles with 57 to 285 CGG repeats, were shown to exhibit normal steady-state levels of FMR1 messenger RNA. However, FMR protein was markedly diminished from transcript with more than 200 repeats. Such transcripts were associated with stalled 40S ribosomal subunits. These results suggest that a structural RNA transition beyond 200 repeats impedes the linear 40S migration along the 5'-untranslated region. This results in translational inhibition by trinucleotide repeat expansion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, Y -- Zhang, F -- Lokey, L K -- Chastain, J L -- Lakkis, L -- Eberhart, D -- Warren, S T -- HD20521/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 May 5;268(5211):731-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732383" target="_blank"〉PubMed〈/a〉

    Description: The human beta-globin locus control region (LCR) controls the transcription, chromatin structure, and replication timing of the entire locus. DNA replication was found to initiate in a transcription-independent manner within a region located 50 kilobases downstream of the LCR in human, mouse, and chicken cells containing the entire human beta-globin locus. However, DNA replication did not initiate within a deletion mutant locus lacking the sequences that encompass the LCR. This mutant locus replicated in the 3' to 5' direction. Thus, interactions between distantly separated sequences can be required for replication initiation, and factors mediating this interaction appear to be conserved in evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aladjem, M I -- Groudine, M -- Brody, L L -- Dieken, E S -- Fournier, R E -- Wahl, G M -- Epner, E M -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, Salk Institute, San Diego, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481774" target="_blank"〉PubMed〈/a〉

    Description: The crystal structure of the tungsten-containing aldehyde ferredoxin oxidoreductase (AOR) from Pyrococcus furiosus, a hyperthermophilic archaeon (formerly archaebacterium) that grows optimally at 100 degrees C, has been determined at 2.3 angstrom resolution by means of multiple isomorphous replacement and multiple crystal form averaging. AOR consists of two identical subunits, each containing an Fe4S4 cluster and a molybdopterin-based tungsten cofactor that is analogous to the molybdenum cofactor found in a large class of oxotransferases. Whereas the general features of the tungsten coordination in this cofactor were consistent with a previously proposed structure, each AOR subunit unexpectedly contained two molybdopterin molecules that coordinate a tungsten by a total of four sulfur ligands, and the pterin system was modified by an intramolecular cyclization that generated a three-ringed structure. In comparison to other proteins, the hyperthermophilic enzyme AOR has a relatively small solvent-exposed surface area, and a relatively large number of both ion pairs and buried atoms. These properties may contribute to the extreme thermostability of this enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, M K -- Mukund, S -- Kletzin, A -- Adams, M W -- Rees, D C -- 1F32 GM15006/GM/NIGMS NIH HHS/ -- GM50775/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 10;267(5203):1463-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Chemistry and Chemical Engineering, Pasadena, CA 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7878465" target="_blank"〉PubMed〈/a〉

    Description: The three-dimensional structure of the complex formed by two plasma proteins, transthyretin and retinol-binding protein, was determined from x-ray diffraction data to a nominal resolution of 3.1 angstroms. One tetramer of transthyretin was bound to two molecules of retinol-binding protein. The two retinol-binding protein molecules established molecular interactions with the same transthyretin dimer, and each also made contacts with one of the other two monomers. Thus, the other two potential binding sites in a transthyretin tetramer were blocked. The amino acid residues of the retinol-binding protein that were involved in the contacts were close to the retinol-binding site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Monaco, H L -- Rizzi, M -- Coda, A -- New York, N.Y. -- Science. 1995 May 19;268(5213):1039-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, University of Pavia, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754382" target="_blank"〉PubMed〈/a〉

    Description: Epstein-Barr virus (EBV) nuclear antigen 2 (EBNA2) is a transcriptional activator that is essential for EBV-driven B cell immortalization. EBNA2 is targeted to responsive promoters through interaction with a cellular DNA binding protein, C promoter binding factor 1 (CBF1). A transcriptional repression domain has been identified within CBF1. This domain also interacts with EBNA2, and repression is masked by EBNA2 binding. Thus, EBNA2 acts by countering transcriptional repression. Mutation at amino acid 233 of CBF1 abolishes repression and correlates with a loss-of-function mutation in the Drosophila homolog Su(H).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hsieh, J J -- Hayward, S D -- CA42245/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Apr 28;268(5210):560-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Molecular Sciences, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7725102" target="_blank"〉PubMed〈/a〉

    Description: Members of the interleukin-6 family of cytokines bind to and activate receptors that contain a common subunit, gp130. This leads to the activation of Stat3 and Stat1, two cytoplasmic signal transducers and activators of transcription (STATs), by tyrosine phosphorylation. Serine phosphorylation of Stat3 was constitutive and was enhanced by signaling through gp130. In cells of lymphoid and neuronal origins, inhibition of serine phosphorylation prevented the formation of complexes of DNA with Stat3-Stat3 but not with Stat3-Stat1 or Stat1-Stat1 dimers. In vitro serine dephosphorylation of Stat3 also inhibited DNA binding of Stat3-Stat3. The requirement of serine phosphorylation for Stat3-Stat3.DNA complex formation was inversely correlated with the affinity of Stat3-Stat3 for the binding site.

    Description: Vascular smooth muscle cell (SMC) proliferation in response to injury is an important etiologic factor in vascular proliferative disorders such as atherosclerosis and restenosis after balloon angioplasty. The retinoblastoma gene product (Rb) is present in the unphosphorylated and active form in quiescent primary arterial SMCs, but is rapidly inactivated by phosphorylation in response to growth factor stimulation in vitro. A replication-defective adenovirus encoding a nonphosphorylatable, constitutively active form of Rb was constructed. Infection of cultured primary rat aortic SMCs with this virus inhibited growth factor-stimulated cell proliferation in vitro. Localized arterial infection with the virus at the time of balloon angioplasty significantly reduced SMC proliferation and neointima formation in both the rat carotid and porcine femoral artery models of restenosis. These results demonstrate the role of Rb in regulating vascular SMC proliferation and suggest a gene therapy approach for vascular proliferative disorders associated with arterial injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, M W -- Barr, E -- Seltzer, J -- Jiang, Y Q -- Nabel, G J -- Nabel, E G -- Parmacek, M S -- Leiden, J M -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):518-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824950" target="_blank"〉PubMed〈/a〉

    Description: The crystal structure of the V alpha domain of a T cell antigen receptor (TCR) was determined at a resolution of 2.2 angstroms. This structure represents an immunoglobulin topology set different from those previously described. A switch in a polypeptide strand from one beta sheet to the other enables a pair of V alpha homodimers to pack together to form a tetramer, such that the homodimers are parallel to each other and all hypervariable loops face in one direction. On the basis of the observed mode of V alpha association, a model of an (alpha beta)2 TCR tetramer can be positioned relative to the major histocompatibility complex class II (alpha beta)2 tetramer with the third hypervariable loop of V alpha over the amino-terminal portion of the antigenic peptide and the corresponding loop of V beta over its carboxyl-terminal residues. TCR dimerization that is mediated by the alpha chain may contribute to the coupling of antigen recognition to signal transduction during T cell activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fields, B A -- Ober, B -- Malchiodi, E L -- Lebedeva, M I -- Braden, B C -- Ysern, X -- Kim, J K -- Shao, X -- Ward, E S -- Mariuzza, R A -- AI31592/AI/NIAID NIH HHS/ -- GM52801/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1821-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Advanced Research in Biotechnology, University of Maryland Biotechnology Institute, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525376" target="_blank"〉PubMed〈/a〉

    Description: Analysis of data collected on 131 species of primates, bats, and insectivores showed that the sizes of brain components, from medulla to forebrain, are highly predictable from absolute brain size by a nonlinear function. The order of neurogenesis was found to be highly conserved across a wide range of mammals and to correlate with the relative enlargement of structures as brain size increases, with disproportionately large growth occurring in late-generated structures. Because the order of neurogenesis is conserved, the most likely brain alteration resulting from selection for any behavioral ability may be a coordinated enlargement of the entire nonolfactory brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finlay, B L -- Darlington, R B -- NS19245/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 16;268(5217):1578-84.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Uris Hall, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7777856" target="_blank"〉PubMed〈/a〉

    Description: The widely used antitumor drug cis-diamminedichloroplatinum(II) (cisplatin or cis-DDP) reacts with DNA, cross-linking two purine residues through the N7 atoms, which reside in the major groove in B-form DNA. The solution structure of the short duplex [d(CAT-AGCTATG)]2 cross-linked at the GC:GC site was determined by nuclear magnetic resonance (NMR). The deoxyguanosine-bridging cis-diammineplatinum(II) lies in the minor groove, and the complementary deoxycytidines are extrahelical. The double helix is locally reversed to a left-handed form, and the helix is unwound and bent toward the minor groove. These findings were independently confirmed by results from a phase-sensitive gel electrophoresis bending assay. The NMR structure differs markedly from previously proposed models but accounts for the chemical reactivity, the unwinding, and the bending of cis-DDP interstrand cross-linked DNA and may be important in the formation and repair of these cross-links in chromatin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, H -- Zhu, L -- Reid, B R -- Drobny, G P -- Hopkins, P B -- GM32681/GM/NIGMS NIH HHS/ -- GM45804/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1842-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Washington, Seattle 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525382" target="_blank"〉PubMed〈/a〉

    Description: Phosphoinositide-3 kinase activity is implicated in diverse cellular responses triggered by mammalian cell surface receptors and in the regulation of protein sorting in yeast. Receptors with intrinsic and associated tyrosine kinase activity recruit heterodimeric phosphoinositide-3 kinases that consist of p110 catalytic subunits and p85 adaptor molecules containing Src homology 2 (SH2) domains. A phosphoinositide-3 kinase isotype, p110 gamma, was cloned and characterized. The p110 gamma enzyme was activated in vitro by both the alpha and beta gamma subunits of heterotrimeric guanosine triphosphate (GTP)-binding proteins (G proteins) and did not interact with p85. A potential pleckstrin homology domain is located near its amino terminus. The p110 gamma isotype may link signaling through G protein-coupled receptors to the generation of phosphoinositide second messengers phosphorylated in the D-3 position.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoyanov, B -- Volinia, S -- Hanck, T -- Rubio, I -- Loubtchenkov, M -- Malek, D -- Stoyanova, S -- Vanhaesebroeck, B -- Dhand, R -- Nurnberg, B -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):690-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Research Unit in Growth Factor Signal Transduction, Medical Faculty, University of Jena, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624799" target="_blank"〉PubMed〈/a〉

    Description: Kidney bean purple acid phosphatase (KBPAP) is an Fe(III)-Zn(II) metalloenzyme resembling the mammalian Fe(III)-Fe(II) purple acid phosphatases. The structure of the homodimeric 111-kilodalton KBPAP was determined at a resolution of 2.9 angstroms. The enzyme contains two domains in each subunit. The active site is located in the carboxyl-terminal domain at the carboxy end of two sandwiched beta alpha beta alpha beta motifs. The two metal ions are 3.1 angstroms apart and bridged monodentately by Asp164. The iron is further coordinated by Tyr167, His325, and Asp135, and the zinc by His286, His323, and Asn201. The active-site structure is consistent with previous proposals regarding the mechanism of phosphate ester hydrolysis involving nucleophilic attack on the phosphate group by an Fe(III)-coordinated hydroxide ion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strater, N -- Klabunde, T -- Tucker, P -- Witzel, H -- Krebs, B -- New York, N.Y. -- Science. 1995 Jun 9;268(5216):1489-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Anorganisch-Chemisches Institut, Universitat Munster, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7770774" target="_blank"〉PubMed〈/a〉

    Description: Lamellar ichthyosis is a severe congenital skin disorder characterized by generalized large scales and variable redness. Affected individuals in three families exhibited drastically reduced keratinocyte transglutaminase (TGK) activity. In two of these families, expression of TGK transcripts was diminished or abnormal and no TGK protein was detected. Homozygous or compound heterozygous mutations of the TGK gene were identified in all families. These data suggest that defects in TGK cause lamellar ichthyosis and that intact cross-linkage of cornified cell envelopes is required for epidermal tissue homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, M -- Rettler, I -- Bernasconi, K -- Frenk, E -- Lavrijsen, S P -- Ponec, M -- Bon, A -- Lautenschlager, S -- Schorderet, D F -- Hohl, D -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Centre Hospitalier Universitaire Vandois (CHUV), Hopital de Beaumont, Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7824952" target="_blank"〉PubMed〈/a〉

    Description: A physical map has been constructed of the human genome containing 15,086 sequence-tagged sites (STSs), with an average spacing of 199 kilobases. The project involved assembly of a radiation hybrid map of the human genome containing 6193 loci and incorporated a genetic linkage map of the human genome containing 5264 loci. This information was combined with the results of STS-content screening of 10,850 loci against a yeast artificial chromosome library to produce an integrated map, anchored by the radiation hybrid and genetic maps. The map provides radiation hybrid coverage of 99 percent and physical coverage of 94 percent of the human genome. The map also represents an early step in an international project to generate a transcript map of the human genome, with more than 3235 expressed sequences localized. The STSs in the map provide a scaffold for initiating large-scale sequencing of the human genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hudson, T J -- Stein, L D -- Gerety, S S -- Ma, J -- Castle, A B -- Silva, J -- Slonim, D K -- Baptista, R -- Kruglyak, L -- Xu, S H -- Hu, X -- Colbert, A M -- Rosenberg, C -- Reeve-Daly, M P -- Rozen, S -- Hui, L -- Wu, X -- Vestergaard, C -- Wilson, K M -- Bae, J S -- Maitra, S -- Ganiatsas, S -- Evans, C A -- DeAngelis, M M -- Ingalls, K A -- Nahf, R W -- Horton, L T Jr -- Anderson, M O -- Collymore, A J -- Ye, W -- Kouyoumjian, V -- Zemsteva, I S -- Tam, J -- Devine, R -- Courtney, D F -- Renaud, M T -- Nguyen, H -- O'Connor, T J -- Fizames, C -- Faure, S -- Gyapay, G -- Dib, C -- Morissette, J -- Orlin, J B -- Birren, B W -- Goodman, N -- Weissenbach, J -- Hawkins, T L -- Foote, S -- Page, D C -- Lander, E S -- HG00017/HG/NHGRI NIH HHS/ -- HG00098/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):1945-54.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead-MIT Center for Genome Research, Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533086" target="_blank"〉PubMed〈/a〉

    Description: Receptor-mediated activation of heterotrimeric guanine nucleotide-binding proteins (G proteins) results in the dissociation of alpha from beta gamma subunits, thereby allowing both to regulate effectors. Little is known about the regions of effectors required for recognition of G beta gamma. A peptide encoding residues 956 to 982 of adenylyl cyclase 2 specifically blocked G beta gamma stimulation of adenylyl cyclase 2, phospholipase C-beta 3, potassium channels, and beta-adrenergic receptor kinase as well as inhibition of calmodulin-stimulated adenylyl cyclases, but had no effect on interactions between G beta gamma and G alpha o. Substitutions in this peptide identified a functionally important motif, Gln-X-X-Glu-Arg, that is also conserved in regions of potassium channels and beta-adrenergic receptor kinases that participate in G beta gamma interactions. Thus, the region defined by residues 956 to 982 of adenylyl cyclase 2 may contain determinants important for receiving signals from G beta gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J -- DeVivo, M -- Dingus, J -- Harry, A -- Li, J -- Sui, J -- Carty, D J -- Blank, J L -- Exton, J H -- Stoffel, R H -- CA-44998/CA/NCI NIH HHS/ -- DK-37219/DK/NIDDK NIH HHS/ -- DK-38761/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 May 26;268(5214):1166-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Mount Sinai School of Medicine, City University of New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7761832" target="_blank"〉PubMed〈/a〉

    Description: Two-dimensional deconvolution techniques are used here to reconstruct age-specific human immunodeficiency virus (HIV) infection rates in the United States from surveillance data on acquired immunodeficiency syndrome (AIDS). This approach suggests that 630,000 to 897,000 adults and adolescents in the United States were living with HIV infection as of January 1993, including 107,000 to 150,000 women. The estimated incidence of HIV infection declined markedly over time among white males, especially those older than 30 years. In contrast, HIV incidence appears to have remained relatively constant among women and minorities. As of January 1993, prevalence was highest among young adults in their late twenties and thirties and among minorities. An estimated 3 percent of black men and 1 percent of black women in their thirties were living with HIV infection as of that date. If infection rates remain at these levels, HIV must be considered as endemic in the United States.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, P S -- New York, N.Y. -- Science. 1995 Nov 24;270(5240):1372-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Cancer Institute, Rockville, MD 20852-4910, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481828" target="_blank"〉PubMed〈/a〉

    Description: Human papillomaviruses (HPVs) are associated with the majority of cervical cancers and encode a transforming protein, E6, that interacts with the tumor suppressor protein p53. Because E6 has p53-independent transforming activity, the yeast two-hybrid system was used to search for other E6-binding proteins. One such protein, E6BP, interacted with cancer-associated HPV E6 and with bovine papillomavirus type 1 (BPV-1) E6. The transforming activity of BPV-1 E6 mutants correlated with their E6BP-binding ability. E6BP is identical to a putative calcium-binding protein, ERC-55, that appears to be localized in the endoplasmic reticulum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J J -- Reid, C E -- Band, V -- Androphy, E J -- R01CA44174/CA/NCI NIH HHS/ -- R29CA56803/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):529-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, New England Medical Center, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624774" target="_blank"〉PubMed〈/a〉

    Description: Intracerebral microdialysis of awake rats was used to monitor the possible release of neurotrophic factors from brain cells in response to injury and excitation. Perfusates were tested with ganglia bioassays and enzyme immunoassay. Trophic activity was released after implantation of the microdialysis probe into the hippocampus but not into the striatum, as assessed by increased nerve fiber outgrowth from Remak's ganglion. Kainic acid treatment significantly increased the release of trophic activity from hippocampal sites. These findings suggest that the brain responds to mechanical injury as well as to certain excitatory stimuli by regional extracellular release of neurotrophic activity that is not identical to the actions of known neurotrophic factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Humpel, C -- Lindqvist, E -- Soderstrom, S -- Kylberg, A -- Ebendal, T -- Olson, L -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):552-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Karolinska Institute, Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624780" target="_blank"〉PubMed〈/a〉

    Description: CD40 is a receptor on the surface of B lymphocytes, the activation of which leads to B cell survival, growth, and differentiation. A yeast two-hybrid screen identified a gene, CRAF1, encoding a protein that interacts directly with the CD40 cytoplasmic tail through a region of similarity to the tumor necrosis factor-alpha (TNF-alpha) receptor-associated factors. Overexpression of a truncated CRAF1 gene inhibited CD40-mediated up-regulation of CD23. A region of CRAF1 was similar to the TNF-alpha receptor-associated factors TRAF1 and TRAF2 and so defined a shared TRAF-C domain that was necessary and sufficient for CD40 binding and homodimerization. The CRAF1 sequence also predicted a long amphipathic helix, a pattern of five zinc fingers, and a zinc ring finger. It is likely that other members of the TNF receptor superfamily use CRAF-related proteins in their signal transduction processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, G -- Cleary, A M -- Ye, Z S -- Hong, D I -- Lederman, S -- Baltimore, D -- 5-T32-GM07367/GM/NIGMS NIH HHS/ -- A122346/PHS HHS/ -- R01-CA55713/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 10;267(5203):1494-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7533327" target="_blank"〉PubMed〈/a〉
