    Emergent properties of reduced-genome Escherichia coli (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-29
    Description: With the use of synthetic biology, we reduced the Escherichia coli K-12 genome by making planned, precise deletions. The multiple-deletion series (MDS) strains, with genome reductions up to 15%, were designed by identifying nonessential genes and sequences for elimination, including recombinogenic or mobile DNA and cryptic virulence genes, while preserving good growth profiles and protein production. Genome reduction also led to unanticipated beneficial properties: high electroporation efficiency and accurate propagation of recombinant genes and plasmids that were unstable in other strains. Eradication of stress-induced transposition evidently stabilized the MDS genomes and provided some of the new properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Posfai, Gyorgy -- Plunkett, Guy 3rd -- Feher, Tamas -- Frisch, David -- Keil, Gunther M -- Umenhoffer, Kinga -- Kolisnychenko, Vitaliy -- Stahl, Buffy -- Sharma, Shamik S -- de Arruda, Monika -- Burland, Valerie -- Harcum, Sarah W -- Blattner, Frederick R -- GM35682/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 May 19;312(5776):1044-6.

    Proviral DNA of a retrovirus, human T-cell leukemia virus, in two patients with AIDS (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-20
    Description: The acquired immune deficiency syndrome (AIDS) is characterized by T-lymphocyte dysfunction and is frequently accompanied by opportunistic infections and Kaposi's sarcoma. Human T-cell leukemia virus (HTLV) is associated with T-cell malignancies and can transform T lymphocytes in vitro. In an attempt to find evidence of HTLV infection in patients with AIDS, DNA from samples of peripheral blood lymphocytes from 33 AIDS patients was analyzed by Southern blot-hybridization with a radiolabeled cloned HTLV DNA probe. Analysis of DNA from both the fresh (uncultured) lymphocytes and from T cells cultured with T-cell growth factor revealed the presence of integrated HTLV proviral sequences in lymphocytes from two of the patients, both of whom had antibody to HTLV. The proviral sequences could not be detected in blood samples obtained from these individuals at a later date, consistent with the possibility that the population of infected cells had become depleted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelmann, E P -- Popovic, M -- Blayney, D -- Masur, H -- Sidhu, G -- Stahl, R E -- Gallo, R C -- New York, N.Y. -- Science. 1983 May 20;220(4599):862-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601822" target="_blank"〉PubMed〈/a〉

    Isolation of human T-cell leukemia virus in acquired immune deficiency syndrome (AIDS) (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-20
    Description: Several isolates of a human type-C retrovirus belonging to one group, known as human T-cell leukemia virus (HTLV), have previously been obtained from patients with adult T-cell leukemia or lymphoma. The T-cell tropism of HTLV and its prevalence in the Caribbean basin prompted a search for it in patients with the epidemic T-cell immune deficiency disorder known as AIDS. Peripheral blood lymphocytes from one patient in the United States and two in France were cultured with T-cell growth factor (TCGF) an shown to express HTLV antigens. Virus from the U.S. patient was isolated and characterized and shown to be related to HTLV subgroup I. The virus was also transmitted into normal human T cells from umbilical cord blood of a newborn. Whether or not HTLV-I or other retroviruses of this family with T-cell tropism cause AIDS, it is possible that patients from whom the virus can be isolated can also transmit it to others. If the target cell of AIDS is the mature T cell as suspected, the methods used in these studies may prove useful for the long-term growth of these cells and for the identification of antigens specific for the etiological agent of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallo, R C -- Sarin, P S -- Gelmann, E P -- Robert-Guroff, M -- Richardson, E -- Kalyanaraman, V S -- Mann, D -- Sidhu, G D -- Stahl, R E -- Zolla-Pazner, S -- Leibowitch, J -- Popovic, M -- New York, N.Y. -- Science. 1983 May 20;220(4599):865-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601823" target="_blank"〉PubMed〈/a〉

    Analysis of hydrothermal vent-associated symbionts by ribosomal RNA sequences (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-04-27
    Description: Ribosomal RNA (rRNA) sequences were used to establish the phylogenetic affiliations of symbioses in which prokaryotes appear to confer sulfur-based chemoautotrophy on their invertebrate hosts. Two submarine hydrothermal vent animals, the vestimentiferan tube worm Riftia pachyptila and the clam Calyptogena magnifica, and a tidal-flat bivalve, Solemya velum, were inspected. 5S rRNA's were extracted from symbiont-bearing tissues, separated into unique forms, and their nucleotide sequences determined and related to other 5S rRNA's in a phylogenetic tree analysis. The prokaryotic symbionts are related to one another and affiliated with the same narrow phylogenetic grouping as Escherichia coli and Pseudomonas aeruginosa. The sequence comparisons suggest that Riftia is more closely related to the bivalves than their current taxonomic status would suggest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stahl, D A -- Lane, D J -- Olsen, G J -- Pace, N R -- New York, N.Y. -- Science. 1984 Apr 27;224(4647):409-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17741220" target="_blank"〉PubMed〈/a〉
