    Description: Cruciform DNA, a non-double helix form of DNA, can be generated as an intermediate in genetic recombination as well as from palindromic sequences under the effect of supercoiling. Eukaryotic cells are equipped with a DNA-binding protein that selectively recognizes cruciform DNA. Biochemical and immunological data showed that this protein is HMG1, an evolutionarily conserved, essential, and abundant component of the nucleus. The interaction with a ubiquitous protein points to a critical role for cruciform DNA conformations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bianchi, M E -- Beltrame, M -- Paonessa, G -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1056-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Heidleberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922595" target="_blank"〉PubMed〈/a〉

    Description: Transcriptional activation of the human interleukin-2 (IL-2) gene, like induction of the IL-2 receptor alpha (IL-2R alpha) gene and the type 1 human immunodeficiency virus (HIV-1), is shown to be modulated by a kappa B-like enhancer element. Mutation of a kappa B core sequence identified in the IL-2 promoter (-206 to -195) partially inhibits both mitogen- and HTLV-I Tax-mediated activation of this transcription unit and blocks the specific binding of two inducible cellular factors. These kappa B-specific proteins (80 to 90 and 50 to 55 kilodaltons) similarly interact with the functional kappa B enhancer present in the IL-2R alpha promoter. These data suggest that these kappa B-specific proteins have a role in the coordinate regulation of this growth factor-growth factor receptor gene system that controls T cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoyos, B -- Ballard, D W -- Bohnlein, E -- Siekevitz, M -- Greene, W C -- A127053-01/PHS HHS/ -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):457-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Medical Center, Department of Microbiology, New York, NY 10029.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497518" target="_blank"〉PubMed〈/a〉

    Description: Soybean cultivars resistant to Pseudomonas syringae pathovar glycinea (Psg), the causal agent of bacterial blight, exhibit a hypersensitive (necrosis) reaction (HR) to infection. Psg strains carrying the avrB gene elicit the HR in soybean cultivars carrying the resistance gene Rpg1. Psg expressing avrB at a high level and capable of eliciting the HR in the absence of de novo bacterial RNA synthesis have been obtained in in vitro culture. Nutritional signals and regions within the Psg hrp gene cluster, an approximately 20-kilobase genomic region also necessary for pathogenicity, control avrB transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huynh, T V -- Dahlbeck, D -- Staskawicz, B J -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1374-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Pathology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2781284" target="_blank"〉PubMed〈/a〉

    Description: Antisense RNA-mediated inhibition of gene expression was used to investigate the biological function of the c-raf-1 gene in a radiation-resistant human squamous carcinoma cell line, SQ-20B. S1 nuclease protection assays revealed that transfection of full-length raf complementary DNA in the antisense orientation (AS) leads to a specific reduction (greater than tenfold) of steady-state levels of the endogenous c-raf-1 sense (S) transcript in SQ-20B cells. In nude mice, the malignant potential of SQ-20B cells transfected with raf (S) was significantly increased relative to that of SQ-20B cells transfected with raf (AS). SQ-20B cells containing transfected raf (S) maintained a radiation-resistant phenotype as compared to those cells harboring the AS version, which appeared to have enhanced radiation sensitivity. These data indicate that the reduced expression of endogenous c-raf-1 is sufficient to modulate the tumorigenicity and the radiation-resistant phenotype of SQ-20B cells, thus implicating c-raf-1 in a pathway important to the genesis of this type of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasid, U -- Pfeifer, A -- Brennan, T -- Beckett, M -- Weichselbaum, R R -- Dritschilo, A -- Mark, G E -- New York, N.Y. -- Science. 1989 Mar 10;243(4896):1354-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiation Medicine, Vincent T.

    Description: During sporulation in Bacillus subtilis, expression of developmental genes spoIVCB and cotD is induced in the mother cell compartment of the sporangium at morphological stages IV and V, respectively. A 27-kilodalton RNA polymerase sigma factor called sigma K (or sigma 27) has been found that causes weak transcription of spoIVCB and strong transcription of cotD. A 14-kD protein was also discovered that changes the specificity of sigma K-containing RNA polymerase, greatly stimulating spoIVCB transcription and markedly repressing cotD transcription. Both sigma K and the 14-kD protein are products of genes known to be required for expression of specific genes in the mother cell. Thus, sigma K directs gene expression in the mother cell and it is proposed that inactivation or sequestering of the 14-kD protein switches the temporal pattern of gene expression during the transition from stages IV to V of development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kroos, L -- Kunkel, B -- Losick, R -- GM18568/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):526-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, Massachusetts 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492118" target="_blank"〉PubMed〈/a〉

    Description: In each cell cycle the complex structure of the chromosome must be replicated accurately. In the last few years there have been major advances in understanding eukaryotic chromosome replication. Patterns of replication origins have been mapped accurately in yeast chromosomes. Cellular replication proteins have been identified by fractionating cell extracts that replicate viral DNA templates in vitro. Cell-free systems that initiate eukaryotic DNA replication in vitro have demonstrated the importance of complex nuclear architecture in the control of DNA replication. Although the events of S phase were relatively neglected for many years, knowledge of DNA replication is now advancing rapidly in step with other phases of the cell cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Laskey, R A -- Fairman, M P -- Blow, J J -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):609-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, England.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683076" target="_blank"〉PubMed〈/a〉

    Description: Embryonal carcinoma (EC) cell lines are models for early cells in mouse embryogenesis. A 300-base pair fragment of the heavy chain enhancer was inactive in F9 EC cells, unlike in other nonlymphoid cells where it has significant activity. Alterations of the octamer motif increased enhancer activity. Nuclear extracts from F9 cells contained an octamer binding protein (NF-A3) that was unique to EC cells; the amount of NF-A3 decreased upon differentiation. It is proposed that NF-A3 represses specific regulatory sequences that contain the octamer motif. Thus, the same DNA sequence mediates either negative or positive transcriptional effects, depending on the cell type.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenardo, M J -- Staudt, L -- Robbins, P -- Kuang, A -- Mulligan, R C -- Baltimore, D -- CA 01074/CA/NCI NIH HHS/ -- HD0063/HD/NICHD NIH HHS/ -- HL37569/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):544-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536195" target="_blank"〉PubMed〈/a〉

    Description: An approach based on the polymerase chain reaction has been devised to clone new members of the family of genes encoding guanosine triphosphate-binding protein (G protein)-coupled receptors. Degenerate primers corresponding to consensus sequences of the third and sixth transmembrane segments of available receptors were used to selectively amplify and clone members of this gene family from thyroid complementary DNA. Clones encoding three known receptors and four new putative receptors were obtained. Sequence comparisons established that the new genes belong to the G protein-coupled receptor family. Close structural similarity was observed between one of the putative receptors and the 5HT1a receptor. Two other molecules displayed common sequence characteristics, suggesting that they are members of a new subfamily of receptors with a very short nonglycosylated (extracellular) amino-terminal extension.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Libert, F -- Parmentier, M -- Lefort, A -- Dinsart, C -- Van Sande, J -- Maenhaut, C -- Simons, M J -- Dumont, J E -- Vassart, G -- New York, N.Y. -- Science. 1989 May 5;244(4904):569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche Interdisciplinaire, Faculte de Medecine, Universite Libre de Bruxelles, Campus Erasme, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541503" target="_blank"〉PubMed〈/a〉

    Description: Quiescent T cells can be induced to express many genes by mitogen or antigen stimulation. The messenger RNAs of some of these genes undergo relatively rapid degradation compared to messenger RNAs from constitutively expressed genes. A T cell activation pathway that specifically regulates the stability of messenger RNAs for the lymphokines interleukin-2, interferon-gamma, tumor necrosis factor-alpha, and granulocyte-macrophage colony-stimulating factor is induced by stimulation of the CD28 surface molecule. This pathway does not directly affect the steady-state messenger RNA level, transcription, or messenger RNA half-life of other T cell activation genes, including c-myc, c-fos, IL-2 receptor, and the 4F2HC surface antigen. These data show that stimuli received at the cell surface can alter gene expression by inducing specific changes in messenger RNA degradation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindstein, T -- June, C H -- Ledbetter, J A -- Stella, G -- Thompson, C B -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):339-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2540528" target="_blank"〉PubMed〈/a〉
