    Notes: Five types of sensilla are situated on the apical area of the labial and maxillary palpi and galea of Cicidela sexguttata. Large, conical, and peg-like sensilla are in rows on the central region of each palpus. These sensilla have a hollow cuticular peg, with an apical pore and multi-innervation. This central region of palpal sensilla is surrounded by campaniform sensilla that are disc-shaped and small conical peg sensilla. A similar type of conical sensillum as the found in the palpal central region is situated around the periphery of the palpal apex and apex of the galea. This conical peg sensillum is located in a shallow depression and is structurally similar to the other peg sensilla, but it has a mechanoreceptor neuron attached to the cuticular base of the sensillum. A long, single, trichoid sensillum is situated in the center of the galea and is hollow, thick-walled, porous, and multi-innervated. The apices of the palpi and galea have a large number of dermal gland openings that actively secrete a substance during the feeding process of the tiger beetle. © 1995 Wiley-Liss, Inc.

    Notes: Epithelial ovarian cancer is a heterogenous disease. Epidemiologic studies have identified risk factors for this disease including advanced age, nulliparity, history of infertility, early age at menarche, late age at menopause, and perhaps ovulation induction. Cohort selection that includes women who have potential precursor lesions and alterations of select biomarkers may prove useful in the design of chemoprevention trials of epithelial ovarian cancer. Nuclear morphometry, specific genetic alterations, and markers of proliferation and differentiation may be useful biomarker to monitor the efficacy of specific interventions.

    Notes: Women at risk of uterine cancer include those with one or more of the following characteristics: obesity, nulliparity, late menopause, diabetes mellitus, prolonged unopposed estrogen use, and tamoxifen therapy. Risk is additionally increased by the presence of endometrial hyperplasia. The incorporation of biomarkers into the selection criteria of cohort groups at risk for developing endometrial cancer offers an innovative approach to the clinical design of chemoprevention trials of endometrial adenocarcinoma. Biomarkers that may be useful in cohort selection include nuclear morphometry, specific genetic abnormalities, and markers of proliferation and differentiation.

    Unusual evolution of 11β- and 17β-hydroxysteroid and retinol dehydrogenasesDedicated to the memory of Carl Monder, who introduced me to the mysteries and wonders of 11β-hydroxysteroid dehydrogenase. (1996)

    Notes: 11β-hydroxysteroid dehydrogenases regulate glucocorticoid concentrations and 17β-hydroxysteroid dehydrogenases regulate estrogen and androgen concentrations in mammals. Phylogenetic analysis of the sequences from two 11β-hydroxysteroid dehydrogenases and four mammalian 17β-hydroxysteroid dehydrogenases indicates unusual evolution in these enzymes. Type 1 11β- and 17β-hydroxysteroid dehydrogenases are on the same branch; Type 2 enzymes cluster on another branch with β-hydroxybutyrate dehydrogenase, 11-cis retinol dehydrogenase and retinol dehydrogenase; Type 3 17β-hydroxysteroid dehydrogenase is on a third branch; while the pig dehydrogenase clusters with a yeast multifunctional enzyme on a fourth branch. Pig 17β-hydroxysteroid dehydrogenase appears to have evolved independently from the other three 17β-hydroxysteroid dehydrogenase dehydrogenases; in which case, the evolution of 17β-hydroxysteroid dehydrogenase activity is an example of functional convergence. The phylogeny also suggests that independent evolution of specificity toward C11 substituents on glucocorticoids and C17 substituents on androgens and estrogens has occurred in Types 1 and 2 11β- and 17β-hydroxysteroid dehydrogenases.

    Control of TRAIL-induced apoptosis by a family of signaling and decoy receptors (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-08
    Description: TRAIL (also called Apo2L) belongs to the tumor necrosis factor family, activates rapid apoptosis in tumor cells, and binds to the death-signaling receptor DR4. Two additional TRAIL receptors were identified. The receptor designated death receptor 5 (DR5) contained a cytoplasmic death domain and induced apoptosis much like DR4. The receptor designated decoy receptor 1 (DcR1) displayed properties of a glycophospholipid-anchored cell surface protein. DcR1 acted as a decoy receptor that inhibited TRAIL signaling. Thus, a cell surface mechanism exists for the regulation of cellular responsiveness to pro-apoptotic stimuli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheridan, J P -- Marsters, S A -- Pitti, R M -- Gurney, A -- Skubatch, M -- Baldwin, D -- Ramakrishnan, L -- Gray, C L -- Baker, K -- Wood, W I -- Goddard, A D -- Godowski, P -- Ashkenazi, A -- New York, N.Y. -- Science. 1997 Aug 8;277(5327):818-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Oncology, Genentech, South San Francisco, CA 94080-4918, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9242611" target="_blank"〉PubMed〈/a〉

    Control of cell fate by a deubiquitinating enzyme encoded by the fat facets gene (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-15
    Description: Ubiquitin is a highly conserved polypeptide found in all eukaryotes. The major function of ubiquitin is to target proteins for complete or partial degradation by a multisubunit protein complex called the proteasome. Here, the Drosophila fat facets gene, which is required for the appropriate determination of particular cells in the fly eye, was shown to encode a ubiquitin-specific protease (Ubp), an enzyme that cleaves ubiquitin from ubiquitin-protein conjugates. The Fat facets protein (FAF) acts as a regulatory Ubp that prevents degradation of its substrate by the proteasome. Flies bearing fat facets gene mutations were used to show that a Ubp is cell type--and substrate-specific and a regulator of cell fate decisions in a multicellular organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Y -- Baker, R T -- Fischer-Vize, J A -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1828-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525378" target="_blank"〉PubMed〈/a〉

    Molecular genetics of plant disease resistance (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-05-05
    Description: Plant breeders have used disease resistance genes (R genes) to control plant disease since the turn of the century. Molecular cloning of R genes that enable plants to resist a diverse range of pathogens has revealed that the proteins encoded by these genes have several features in common. These findings suggest that plants may have evolved common signal transduction mechanisms for the expression of resistance to a wide range of unrelated pathogens. Characterization of the molecular signals involved in pathogen recognition and of the molecular events that specify the expression of resistance may lead to novel strategies for plant disease control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staskawicz, B J -- Ausubel, F M -- Baker, B J -- Ellis, J G -- Jones, J D -- New York, N.Y. -- Science. 1995 May 5;268(5211):661-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of California, Berkeley 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732374" target="_blank"〉PubMed〈/a〉

    Selective trafficking of KNOTTED1 homeodomain protein and its mRNA through plasmodesmata (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-22
    Description: Plasmodesmata are intercellular organelles in plants that establish cytoplasmic continuity between neighboring cells. Microinjection studies showed that plasmodesmata facilitate the cell-to-cell transport of a plant-encoded transcription factor, KNOTTED1 (KN1). KN1 can also mediate the selective plasmodesmal trafficking of kn1 sense RNA. The emerging picture of plant development suggests that cell fate is determined at least in part by supracellular controls responding to cellular position as well as lineage. One of the mechanisms that enables the necessary intercellular communication appears to involve transfer of informational molecules (proteins and RNA) through plasmodesmata.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lucas, W J -- Bouche-Pillon, S -- Jackson, D P -- Nguyen, L -- Baker, L -- Ding, B -- Hake, S -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):1980-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Plant Biology, University of California, Davis 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533088" target="_blank"〉PubMed〈/a〉
