Peg3 Binds To H19-Icr As A Transcriptional Repressor, An Ye, Hongzhi He, Joomyeong Kim Dec 2016

Peg3 Binds To H19-Icr As A Transcriptional Repressor, An Ye, Hongzhi He, Joomyeong Kim

Faculty Publications

© 2016 Taylor & Francis Group, LLC. Paternally expressed gene 3 (Peg3) encodes a DNA-binding protein with 12 C2H2 zinc finger motifs. In the current study, we performed ChIP-seq using mouse embryonic fibroblast (MEF) cells. This experiment identified a set of 16 PEG3 genomic targets, the majority of which overlapped with the promoter regions of genes with oocyte expression. These potential downstream genes were upregulated in MEF cells lacking PEG3 protein, suggesting a potential repressor role for PEG3. Our study also identified the imprinting control region (ICR) of H19 as a genomic target. According to the results, PEG3 binds to …

A Review Of The Tawny Crazy Ant, Nylanderia Fulva, An Emergent Ant Invader In The Southern United States: Is Biological Control A Feasible Management Option?, Zinan Wang, Lori Moshman, Emily C. Kraus, Blake E. Wilson, Namoona Acharya, Rodrigo Diaz

Faculty Publications

© 2016 by the authors; licensee MDPI, Basel, Switzerland. The tawny crazy ant, Nylanderia fulva (Mayr) (Hymenoptera: Formicidae), has invaded states of the U.S. including Texas, Louisiana, Mississippi, Alabama, Florida, and Georgia. Native to South America, N. fulva is considered a pest in the U.S. capable of annoying homeowners and farmers, as well as displacing native ant species. As it continues to expand its range, there is a growing need to develop novel management techniques to control the pest and prevent further spread. Current management efforts rely heavily on chemical control, but these methods have not been successful. A review …

Treescaper: Visualizing And Extracting Phylogenetic Signal From Sets Of Trees, Wen Huang, Guifang Zhou, Melissa Marchand, Jeremy R. Ash, David Morris, Paul Van Dooren, Jeremy M. Brown, Kyle A. Gallivan, Jim C. Wilgenbusch Dec 2016

Treescaper: Visualizing And Extracting Phylogenetic Signal From Sets Of Trees, Wen Huang, Guifang Zhou, Melissa Marchand, Jeremy R. Ash, David Morris, Paul Van Dooren, Jeremy M. Brown, Kyle A. Gallivan, Jim C. Wilgenbusch

Faculty Publications

© The Author 2016. Modern phylogenomic analyses often result in large collections of phylogenetic trees representing uncertainty in individual gene trees, variation across genes, or both. Extracting phylogenetic signal from these tree sets can be challenging, as they are difficult to visualize, explore, and quantify. To overcome some of these challenges, we have developed TreeScaper, an application for tree set visualization as well as the identification of distinct phylogenetic signals. GUI and command-line versions of TreeScaper and a manual with tutorials can be downloaded from https://github.com/ whuang08/TreeScaper/releases.

The Target Of Β-Expansin Expb1 In Maize Cell Walls From Binding And Solid-State Nmr Studies, Tuo Wang, Yuning Chen, Akira Tabuchi, Daniel J. Cosgrove, Mei Hong Dec 2016

The Target Of Β-Expansin Expb1 In Maize Cell Walls From Binding And Solid-State Nmr Studies, Tuo Wang, Yuning Chen, Akira Tabuchi, Daniel J. Cosgrove, Mei Hong

Faculty Publications

© 2016 American Society of Plant Biologists. All rights reserved. The wall-loosening actions of β-expansins are known primarily from studies of EXPB1 extracted from maize (Zea mays) pollen. EXPB1 selectively loosens cell walls (CWs) of grasses, but its specific binding target is unknown. We characterized EXPB1 binding to sequentially extracted maize CWs, finding that the protein primarily binds glucuronoarabinoxylan (GAX), the major matrix polysaccharide in grass CWs. This binding is strongly reduced by salts, indicating that it is predominantly electrostatic in nature. For direct molecular evidence of EXPB1 binding, we conducted solid-state nuclear magnetic resonance experiments using paramagnetic relaxation enhancement …

Capsular Polysaccharide Production And Serum Survival Of Vibrio Vulnificus Are Dependent On Antitermination Control By Rfah, Shana B. Garrett, Katherine L. Garrison-Schilling, Jeffrey T. Cooke, Gregg S. Pettis Dec 2016

Capsular Polysaccharide Production And Serum Survival Of Vibrio Vulnificus Are Dependent On Antitermination Control By Rfah, Shana B. Garrett, Katherine L. Garrison-Schilling, Jeffrey T. Cooke, Gregg S. Pettis

Faculty Publications

© 2016 Federation of European Biochemical Societies The human pathogen Vibrio vulnificus undergoes phase variation among colonial morphotypes, including a virulent opaque form which produces capsular polysaccharide (CPS) and a translucent phenotype that produces little or no CPS and is attenuated. Here, we found that a V. vulnificus mutant defective for RfaH antitermination control showed a diminished capacity to undergo phase variation and displayed significantly reduced distal gene expression within the Group I CPS operon. Moreover, the rfaH mutant produced negligible CPS and was highly sensitive to killing by normal human serum, results which indicate that RfaH is likely essential …

Entomopathogenic Nematodes Combined With Adjuvants Presents A New Potential Biological Control Method For Managing The Wheat Stem Sawfly, Cephus Cinctus (Hymenoptera: Cephidae), Scott L. Portman, Sindhu M. Krishnankutty, Gadi V.P. Reddy Dec 2016

Entomopathogenic Nematodes Combined With Adjuvants Presents A New Potential Biological Control Method For Managing The Wheat Stem Sawfly, Cephus Cinctus (Hymenoptera: Cephidae), Scott L. Portman, Sindhu M. Krishnankutty, Gadi V.P. Reddy

Faculty Publications

The wheat stem sawfly, (Cephus cinctus Norton) Hymenoptera: Cephidae, has been a major pest of winter wheat and barley in the northern Great Plains for more than 100 years. The insect's cryptic nature and lack of safe chemical control options make the wheat stem sawfly (WSS) difficult to manage; thus, biological control offers the best hope for sustainable management of WSS. Entomopathogenic nematodes (EPNs) have been used successfully against other above-ground insect pests, and adding adjuvants to sprays containing EPNs has been shown to improve their effectiveness. We tested the hypothesis that adding chemical adjuvants to sprays containing EPNs will …

Sequence Capture And Next-Generation Sequencing Of Ultraconserved Elements In A Large-Genome Salamander, Catherine E. Newman, Christopher C. Austin Dec 2016

Sequence Capture And Next-Generation Sequencing Of Ultraconserved Elements In A Large-Genome Salamander, Catherine E. Newman, Christopher C. Austin

Faculty Publications

© 2016 John Wiley & Sons Ltd Amidst the rapid advancement in next-generation sequencing (NGS) technology over the last few years, salamanders have been left behind. Salamanders have enormous genomes—up to 40 times the size of the human genome—and this poses challenges to generating NGS data sets of quality and quantity similar to those of other vertebrates. However, optimization of laboratory protocols is time-consuming and often cost prohibitive, and continued omission of salamanders from novel phylogeographic research is detrimental to species facing decline. Here, we use a salamander endemic to the southeastern United States, Plethodon serratus, to test the utility …

Does Leaf Shedding Protect Stems From Cavitation During Seasonal Droughts? A Test Of The Hydraulic Fuse Hypothesis, Brett T. Wolfe, John S. Sperry, Thomas A. Kursar Dec 2016

Does Leaf Shedding Protect Stems From Cavitation During Seasonal Droughts? A Test Of The Hydraulic Fuse Hypothesis, Brett T. Wolfe, John S. Sperry, Thomas A. Kursar

Faculty Publications

During droughts, leaves are predicted to act as ‘hydraulic fuses’ by shedding when plants reach critically low water potential (Ψplant), thereby slowing water loss, stabilizing Ψplant and protecting against cavitation-induced loss of stem hydraulic conductivity (Ks). We tested these predictions among trees in seasonally dry tropical forests, where leaf shedding is common, yet variable, among species. We tracked leaf phenology, Ψplant and Ks in saplings of six tree species distributed across two forests. Species differed in their timing and extent of leaf shedding, yet converged in shedding leaves as they approached the Ψplant value associated with a 50% loss of …

Effective conservation measures for endangered species require basic knowledge of habitat use and critical environmental variables influencing the species' occurrence. However, setting priorities may be difficult when multiple endangered species inhabit the same area and differ in habitat use. This study characterized the physical and chemical environment at 30 sites along a 2.5 km stretch of stream associated with the Baños del Azufre hydrogen sulphide spring complex, home to the only population of the widemouth gambusia (Gambusia eurystoma) in existence. Also present in the spring is Poecilia sulphuraria, a narrowly endemic and endangered species known from only a few populations. …

Marco, Eun Bae Kim, Michael L. Goodson, Michael J. Keenan, Tamara N. Dunn, Knud Erik Bach Knudsen, Roy J. Martin, Sean H. Adams

Faculty Publications

Background: High-amylose-maize resistant starch type 2 (HAMRS2) is a fermentable dietary fiber known to alter the gut milieu, including the gut microbiota, which may explain the reported effects of resistant starch to ameliorate obesityassociated metabolic dysfunction. Objective: Our working hypothesis was that HAMRS2-induced microbiome changes alter gut-derived signals (i.e., xenometabolites) reaching the liver via the portal circulation, in turn altering liver metabolism by regulating gene expression and other pathways. Methods: We used a multi-omics systems biology approach to characterize HAMRS2-driven shifts to the cecal microbiome, liver metabolome, and transcriptome, identifying correlates between microbial changes and liver metabolites under obesogenic conditions …

Parental And Sexual Conflicts Over The Peg3 Imprinted Domain, Hongzhi He, Bambarendage P.U. Perera, An Ye, Joomyeong Kim Nov 2016

Parental And Sexual Conflicts Over The Peg3 Imprinted Domain, Hongzhi He, Bambarendage P.U. Perera, An Ye, Joomyeong Kim

Faculty Publications

© 2016 The Author(s). In the current study, the imprinting control region of the mouse Peg3 domain was deleted to test its functional impact on animal growth and survival. The paternal transmission of the deletion resulted in complete abolition of the transcription of two paternally expressed genes, Peg3 and Usp29, causing the reduced body weight of the pups. In contrast, the maternal transmission resulted in the unexpected transcriptional up-regulation of the remaining paternal allele of both Peg3 and Usp29, causing the increased body weight and survival rates. Thus, the imprinted maternal allele of the ICR may be a suppressor antagonistic …

Faculty Publications

Copyright © 2015 Wolters Kluwer Health, Inc. The Caenorhabditis elegans model is a rapid and inexpensive method to address pharmacologic questions. We describe the use of C. elegans to explore 2 pharmacologic questions concerning candidate antiobesity drugs and illustrate its potential usefulness in pharmacologic research: (1) to determine a ratio of betahistine-olanzapine that blocks the olanzapine-induced intestinal fat deposition (IFD) as detected by Nile red staining and (2) to identify the mechanism of action of a pharmaceutical candidate AB-101 that reduces IFD. Olanzapine (53 mg/mL) increased the IFD (12.1 6 0.1%, P < 0.02), which was blocked by betahistine (763 mg/mL, 39.3 6 0.01%, P < 0.05) in wild-type C. elegans (N2). AB-101 (1.0%) reduced the IFD in N2 (P < 0.05), increased the pharyngeal pumping rate (P < 0.05), and reversed the elevated IFD induced by protease inhibitors atazanavir and ritonavir (P < 0.05). AB-101 did not affect IFD in a ACS null mutant strain acs-4(ok2872) III/hT2[bli-4(e937) let-?(q782) qIs48](I;III) suggesting an involvement of the lipid oxidation pathway and an upregulation of CPT-1. Our studies suggest that C. elegans may be used as a resource in pharmacologic research. This article is intended to stimulate a greater appreciation of its value in the development of new pharmaceutical interventions.

Faculty Publications

© 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim This review focuses on a group of heme peroxidases that retain the catalase fold in structure, yet show little or no reaction with hydrogen peroxide. Instead of having a role in oxidative defense, these enzymes are involved in secondary metabolite biosynthesis. The prototypical enzyme is catalase-related allene oxide synthase, an enzyme that converts a specific fatty acid hydroperoxide to the corresponding allene oxide (epoxide). Other catalase-related enzymes form allylic epoxides, aldehydes, or a bicyclobutane fatty acid. In all catalases (including these relatives), a His residue on the distal face of the …

Syndepositional Diagenetic Control Of Molybdenum Isotope Variations In Carbonate Sediments From The Bahamas, Stephen J. Romaniello, Achim D. Herrmann, Ariel D. Anbar Nov 2016

Syndepositional Diagenetic Control Of Molybdenum Isotope Variations In Carbonate Sediments From The Bahamas, Stephen J. Romaniello, Achim D. Herrmann, Ariel D. Anbar

Faculty Publications

© 2016 Elsevier B.V. Molybdenum (Mo) isotope variations recorded in black shales provide important constraints on marine paleoredox conditions. However, suitable shales are not ubiquitous in the geologic record. Moreover, reliable reconstruction of Mo isotope records from shales requires deposition from a water column containing very high concentrations of sulfide-a condition which is both rare and difficult to verify with certainty when examining preserved sediments. The utility of Mo isotopic records could be improved if reconstructions were possible using alternative lithologies, such as marine carbonates, which are more abundant in the geologic record.Here, we focus on the role of early …

Fluctuating Temperatures Alter Environmental Pathogen Transmission In A Daphnia–Pathogen System, Tad Dallas, John M. Drake Nov 2016

Fluctuating Temperatures Alter Environmental Pathogen Transmission In A Daphnia–Pathogen System, Tad Dallas, John M. Drake

Faculty Publications

© 2016 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd. Environmental conditions are rarely constant, but instead vary spatially and temporally. This variation influences ecological interactions and epidemiological dynamics, yet most experimental studies examine interactions under constant conditions. We examined the effects of variability in temperature on the host–pathogen relationship between an aquatic zooplankton host (Daphnia laevis) and an environmentally transmitted fungal pathogen (Metschnikowia bicuspidata). We manipulated temperature variability by exposing all populations to mean temperatures of 20°C for the length of the experiments, but introducing periods of 1, 2, and 4 hr each day where …
