Two Splice Variants Of Nopp140 In Drosophila Melanogaster, John M. Waggener, Patrick J. Dimario Feb 2002

Two Splice Variants Of Nopp140 In Drosophila Melanogaster, John M. Waggener, Patrick J. Dimario

Faculty Publications

The Nopp140 gene of Drosophila maps within 79A5 of chromosome 3. Alternative splicing yields two variants. DmNopp140 (654 residues) is the sequence homolog of vertebrate Nopp140. Its carboxy terminus is 64% identical to that of the prototypical rat Noppl40. DmNopp140-RGG (688 residues) is identical to DmNopp140 throughout its first 551 residues, but its carboxy terminus contains a glycine/arginine-rich domain that is often found in RNA-binding proteins such as vertebrate nucleolin. Both Drosophila variants localize to nucleoli in Drosophila Schneider II cells and Xenopus oocytes, specifically within the dense fibrillar components. In HeLa cells, DmNopp140-RGG localizes to intact nucleoli, whereas DmNopp140 …

Interferon-Γ-Mediated Activation And Ubiquitin-Proteasome-Dependent Degradation Of Pparγ In Adipocytes, Z. Elizabeth Floyd, Jacqueline M. Stephens Feb 2002

Interferon-Γ-Mediated Activation And Ubiquitin-Proteasome-Dependent Degradation Of Pparγ In Adipocytes, Z. Elizabeth Floyd, Jacqueline M. Stephens

Faculty Publications

Interferon-γ (IFNγ) treatment of adipocytes results in a down-regulation of the peroxisome proliferator-activated receptor γ (PPARγ). The decrease in PPARγ expression is mediated by inhibition of PPARγ synthesis and increased degradation of PPARγ. In this study, we demonstrate that both PPARγ1 and PPARγ2 are targeted to the proteasome under basal conditions and that PPARγ1 is more labile than PPARγ2. The IFNγ-induced increase in PPARγ turnover is blocked by proteasome inhibition and is accompanied by an increase in PPARγ-polyubiquitin conjugates. In addition, IFNγ treatment results in the transcriptional activation of PPARγ. Similar to ligand-dependent activation of PPARγ, IFNγ-induced activation was greater …

Sediment Denitrification In The Gulf Of Mexico Zone Of Hypoxia, C R. Childs, N N. Rabalais, R. Eugene Turner, L M. Proctor, C R. Childs

Faculty Publications

The largest zone of anthropogenic bottom water hypoxia in the Western Hemisphere occurs seasonally in the northern Gulf of Mexico between the Mississippi River delta and the coast of eastern Texas. This zone of hypoxia reaches its greatest extent in the summer months and is a consequence of seasonal stratification of the water column combined with the decomposition of organic matter derived from accelerated rates of primary production. This enhanced productivity is driven primarily by the input of inorganic nitrogen from the Mississippi River. There are 3 likely sinks for fixed nitrogen within this zone of hypoxia: sequestration in the …

Troponin-Tropomyosin: An Allosteric Switch Or A Steric Blocker?, Andrea M. Resetar, Jacqueline M. Stephens, Joseph M. Chalovich Jan 2002

Troponin-Tropomyosin: An Allosteric Switch Or A Steric Blocker?, Andrea M. Resetar, Jacqueline M. Stephens, Joseph M. Chalovich

Faculty Publications

The interaction of myosin subfragment 1 (S1) with actin-tropomyosin-troponin (regulated actin) is highly nucleotide dependent. The binding of S1 or S1-ADP (but not S1-ATP nor N,N′-ρ-phenylenedimaleimide-modified S1-ATP) to regulated actin activates ATP hydrolysis even in the absence of Ca2+. Investigations with S1 and S1-ADP have led to the idea that some actin sites are directly blocked toward the binding of S1 either by tropomyosin or troponin. The blocked state is thought to occur only at ionic strengths greater than 50 mM. The question is whether nonactivating S1 binding is blocked under the same conditions. We show that troponin inhibits binding …

DNA-based vaccines were employed to assess protective immunity against herpes simplex virus in experimental infections of hairless (strain SKH1) and BALB/c mice. Mice were vaccinated with plasmids containing the herpes simplex virus type-1 (HSV-1) glycoprotein B (gB) or D (gD) genes under the human cytomegalovirus immediate-early promoter control. Vaccines were injected intramuscularly (i.m.) or intraperitoneally (i.p.) as purified DNA alone or as formulations supplemented with different non-ionic block copolymers. Antibody responses were assessed by immunofluorescence and radioimmunoprecipitation assays. Mice inoculated with either gB or gD plasmid, alone or with non-ionic block copolymers CRL 1029 and CRL 1190, produced high levels …

Capacitative Calcium Entry Mechanism In Porcine Oocytes, Zoltán Macháty, Jagdeece J. Ramsoondar, Aaron J. Bonk, Kenneth R. Bondioli, Randall S. Prather

Faculty Publications

The presence of the capacitative Ca2+ entry mechanism was investigated in porcine oocytes. In vitro-matured oocytes were treated with thapsigargin in Ca2+-free medium for 3 h to deplete intracellular calcium stores. After restoring extracellular calcium, a large calcium influx was measured by using the calcium indicator dye fura-2, indicating capacitative Ca2+ entry. A similar divalent cation influx could also be detected with the Mn2+-quench technique after inositol 1,4,5-triphosphate-induced Ca2+ release. In both cases, lanthanum, the Ca2+ permeable channel inhibitor, completely blocked the influx caused by store depletion. Heterologous expression of Drosophila trp in porcine oocytes enhanced the thapsigargin-induced Ca2+ influx. …

Faculty Publications

Bovine brucellosis is a serious zoonotic disease affecting some populations of Rocky Mountain elk (Cervus elaphus nelsoni) and bison (Bison bison) in the Greater Yellowstone Area, USA. The fear that elk and/or bison may spread Brucella abortus to livestock has prompted efforts to reduce or eliminate the disease in wildlife. Brucella abortus strain RB51 (RB51) vaccine has recently been approved for use in cattle. Unlike strain 19 vaccine, RB51 does not cause false positive reactions on standard brucellosis serologic tests. If effective, it may become the vaccine of choice for wildlife. In February 1995, 45 serologically negative female elk calves …

Brucella Abortus Strain Rb51 Vaccination In Elk Ii. Failure Of High Dosage To Prevent Abortion, Terry J. Kreeger, Walter E. Cook, William H. Edwards, Philip H. Elzer, Steven C. Olsen

Faculty Publications

Brucella abortus strain RB51 is used as a vaccine because it induces antibodies that do not react on standard serologic tests for brucellosis allowing differentiation between vaccination and infection. Strain RB51 was evaluated in captive elk (Cervus elaphus) to determine if vaccination protected against abortion following experimental challenge. Thirty elk were vaccinated intramuscularly with 1.0 × 1010 colony-forming units (CFU) of strain RB51 in March 1998. Fourteen of these were given a booster dose of 1.13 × 1010 CFU exactly 1 yr later. All vaccinated elk seroconverted via a modified dot blot assay to strain RB51 with the booster group …

The Ta (transcribed, subset a) subfamily of L1 LINEs (long interspersed elements) is characterized by a 3-bp ACA sequence in the 3′ untranslated region and contains ∼520 members in the human genome. Here, we have extracted 468 Ta L1Hs (L1 human specific) elements from the draft human genomic sequence and screened individual elements using polymerase-chain-reaction (PCR) assays to determine their phylogenetic origin and levels of human genomic diversity. One hundred twenty-four of the elements amenable to complete sequence analysis were full length (∼6 kb) and have apparently escaped any 5′ truncation. Forty-four of these full-length elements have two intact open …

The Depth Of Porphyrin In A Membrane And The Membrane's Physical Properties Affect The Photosensitizing Efficiency, Adina Lavi, Hana Weitman, Robert T. Holmes, Kevin M. Smith, Benjamin Ehrenberg

Faculty Publications

Photosensitized biological processes, as applied in photodynamic therapy, are based on light-triggered generation of molecular singlet oxygen by a membrane-residing sensitizer. Most of the sensitizers currently used are hydrophobic or amphiphilic porphyrins and their analogs. The possible activity of the short-lived singlet oxygen is limited to the time it is diffusing in the membrane, before it emerges into the aqueous environment. In this paper we demonstrate the enhancement of the photosensitization process that is obtained by newly synthesized protoporphyrin derivatives, which insert their tetrapyrrole chromophore deeper into the lipid bilayer of liposomes. The insertion was measured by fluorescence quenching by …

Faculty Publications

Mapping by admixture linkage disequilibrium (MALD) is a potentially powerful technique for the mapping of complex genetic diseases. The practical requirements of this method include (a) a set of markers spanning the genome that have large allele-frequency differences between the parental ethnicities contributing to the admixed population and (b) an understanding of the extent of admixture in the study population. To this end, a DNA-pooling technique was used to screen microsatellite and diallelic insertion/deletion markers for allele-frequency differences between putative representatives of the parental populations of the admixed Mexican American (MA) and African American (AA) populations. Markers with promising pooled …

Effect Of Sweeteners On The Microstructure Of Yogurt, Zahur Z. Haque, Kayanush J. Aryana Jan 2002

Effect Of Sweeteners On The Microstructure Of Yogurt, Zahur Z. Haque, Kayanush J. Aryana

Faculty Publications

The objective was to determine the effect of a peptide sweetener, Aspartame, compared to a carbohydrate sweetener, sucrose, on the microstructure of yogurt. Microstructure was determined by transmission and scanning electron microscopy. Without the sweeteners, casein micelles, that make up the yogurt matrix, were observed in single longitudinal polymers. When Aspartame was used, casein micelles formed double longitudinal polymers. In comparison sugar caused casein micelles to form clusters. Data show that type of sweetener impacts state of association of casein micelles and thus effects microstructure.

Flight potential, a poorly understood phenomenon in the migratory true armyworm, Pseudaletia unipuncta (Haworth), was investigated in a laboratory population using tethered-flight techniques. True armyworm exhibited strong flight potential relative to other known migratory noctuids whose flight potentials were previously determined by similar techniques. Flight potential was generally low for 1-d-old moths and increased with age to day 5 of adult life. Flight speed and distance flown decreased for female moths from day 5 to day 10 as their reproductive system developed. The greatest average flight speed, total flight duration, and distance flown was exhibited by 5-d-old females and 10-d-old …

Using Simple Marginal Analysis And Density Management Diagrams For Prescribing Density Management, Thomas J. Dean, S. Joseph Chang Jan 2002

Using Simple Marginal Analysis And Density Management Diagrams For Prescribing Density Management, Thomas J. Dean, S. Joseph Chang

Faculty Publications

This article presents a procedure to produce management regimes that not only maximize land value but also reflect stand development with simple marginal analyses of the accumulation and control of growing stock. An upper limit of growing stock is determined by translating management objectives into a future desired structure, and with this value as a guide for thinning age, marginal analysis is used to determine the planting density and the residual basal area after thinning. The procedure is demonstrated for a hypothetical loblolly pine plantation growing on land with a site index of 65 ft at 25 yr. The effects …
