The number of translational scientific discoveries and technological innovations derived from the center’s research labs over the course of the past three decades has been remarkable. Equally remarkable have been the number of scientific awards and honors, including Nobel prizes, received by Beckman faculty and the number of young scientists mentored by Beckman faculty who have gone on to prominent positions in academia, bio-technology and related fields. This year we include several featured articles on these accomplishments. In the field of translational medicine, these discoveries range from the causes of skin, bladder and other cancers, to the identification of human stem cells, from the design of new antifungals and antibiotics to the molecular underpinnings of autism, and from opioids for pain

BERNSTEIN,1 NAHUM SONENBERG.~ AND DAVID BALTIMOREh Whitehead Institute for Biomedical Research, Cambridge, Massachusetts 02142, and Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, 1 and Department of Biochemistry, McGill Unirersity, Montreal, Quebec, Canada H3G I Y6~ Received 20 May 1985/Accepted 1 August 1985 A poliovirus type I (Mahoney strain) mutant was obtained by inserting three base pairs into an infectious eDNA clone. The extra amino acid encoded by the insertion was in the amino-terminal (protein 8) portion of the P2 segment of the polyprotein. The mutant virus makes small plaques on HeLa and monkey kidney (CV-1) cells at all temperatures. It lost the ability to mediate the selective inhibition of host cell translation which ordinarily occurs in the first few hours after infection. As an apparent consequence, the mutant synthesizes far less protein than does wild-type virus. In mutant-infected CV-1 cells enough protein was produced to permit a normal course of RNA replication, but the yield of progeny virus was very low. In mutant-infected He La cells there was a premature cessation of both cellular and viral protein synthesis followed by a premature halt of viral RNA synthesis. This nonspecific translational inhibition was distinguishable from wild-type-mediated inhibition and did not appear to be part of an interferon or heat shock response.

  • Surrender, Avoidance and Subversion by Microorganisms
    REVIEWS CELLULAR AUTOPHAGY: SURRENDER, AVOIDANCE AND SUBVERSION BY MICROORGANISMS Karla Kirkegaard, Matthew P.Taylor and William T. Jackson Intracellular bacteria and viruses must survive the vigorous antimicrobial responses of their hosts to replicate successfully. The cellular process of autophagy — in which compartments bound by double membranes engulf portions of the cytosol and then mature to degrade their cytoplasmic contents — is likely to be one such host-cell response. Several lines of evidence show that both bacteria and viruses are vulnerable to autophagic destruction and that successful pathogens have evolved strategies to avoid autophagy, or to actively subvert its components, to promote their own replication. The molecular mechanisms of the avoidance and subversion of autophagy by microorganisms will be the subject of much future research, not only to study their roles in the replication of these microorganisms, but also because they will provide — as bacteria and viruses so often have — unique tools to study the cellular process itself. 6,7 4 DAUER Cellular autophagy involves the sequestration of thaliana and C. elegans ,wild-type autophagy genes An arrested stage in regions of the cytosol within double-membrane-bound are required to prevent premature senescence.

  • Homeotic Gene Antennapedia Mrna Contains 5'-Noncoding Sequences That Confer Translational Initiation by Internal Ribosome Binding
    Downloaded from genesdev.cshlp.org on October 9, 2021 - Published by Cold Spring Harbor Laboratory Press Homeotic gene Antennapedia mRNA contains 5'-noncoding sequences that confer translational initiation by internal ribosome binding Soo-Kyung OH, 1 Matthew P. Scott, 2 and Peter Sarnow 1'3 ~Department of Biochemistry, Biophysics and Genetics, 3Department of Microbiology and Immunology, University of Colorado Health Sciences Center, Denver, Colorado 80262 USA; 2Departments of Developmental Biology and Genetics, Stanford University School of Medicine, Stanford, California 94305-5427 USA The Antennapedia (Antp) homeotic gene of Drosophila melanogaster has two promoters, P1 and P2. The resulting Antp mRNAs contain 1512-nucleotide (P1) and 1727-nucleotide (P2) 5'-noncoding regions, composed of exons A, B, D, and E (PI) or exons C, D, and E (P2), respectively. Multiple AUG codons are present in exons A, B, and C. We have found that 252-nucleotide exon D, common to mRNAs from both transcription units and devoid of AUG codons, can mediate initiation of translation by internal ribosome binding in cultured cells. Many mRNAs in Drosophila contain long 5'-noncoding regions with apparently unused AUG codons, suggesting that internal ribosome binding may be a common mechanism of translational initiation, and possibly its regulation, in Drosoptu'la.

The homeotic genes required for segments in Drosophila similarly, exon C contains 15 upstream AUG codons. All melanogaster to have different developmental fates are of these upstream AUG codons are followed by very expressed in some segment primordia but not in others.

  • Functional Oligomerization of Poliovirus RNA-Dependent RNA Polymerase

PATA,1'2 STEVE C. SCHULTZ,2 and KARLA KIRKEGAARD1 Department of Molecular, Cellular, and Developmental Biology, Howard Hughes Medical Institute, University of Colorado, Boulder, Colorado 80309-0347, USA 2 Department of Chemistry and Biochemistry, University of Colorado, Boulder, Colorado 80309-0215, USA ABSTRACT Using a hairpin primeritemplate RNA derived from sequences present at the 3' end of the poliovirus genome, we investigated the RNA-binding and elongation activities of highly purified poliovirus 3D polymerase. We found that surprisingly high polymerase concentrations were required for efficient template utilization. Binding of template RNAs appeared to be the primary determinant of efficient utilization because binding and elonga- tion activities correlated closely. Using a three-filter binding assay, polymerase binding to RNA was found to be highly cooperative with respect to polymerase concentration. At pH 5.5, where binding was most coopera- tive, a Hill coefficient of 5 was obtained, indicating that several polymerase molecules interact to retain the 110-nt RNA in a filter-bound complex. Chemical crosslinking with glutaraldehyde demonstrated physical polymerase-polymerase interactions, supporting the cooperative binding data. We propose a model in which poliovirus 3D polymerase functions both as a catalytic polymerase and as a cooperative single-stranded RNA- binding protein during RNA-dependent RNA synthesis. Keywords: RNA replicase; single-stranded RNA-binding protein INTRODUCTION known to be required for RNA synthesis: 2B, 2C, 2BC, 3A, 3B, 3AB, and 3CD (Wimmer et al., 1993).
