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 …

Habitat Use By Two Extremophile, Highly Endemic, And Critically Endangered Fish Species (Gambusia Eurystoma And Poecilia Sulphuraria; Poeciliidae), Zachary W. Culumber, Garrett W. Hopper, Nicholas Barts, Courtney N. Passow, Samuel Morgan, Anthony Brown, Lenin Arias-Rodriguez, Michael Tobler

Faculty Publications

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. …

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 …

Using Caenorhabditis Elegans As A Model For Obesity Pharmacology Development, Jolene Zheng, Joseph R. Vasselli, Jason F. King, Michael L. King, Wenqian We, Zachary Fitzpatrick, William D. Johnson, John W. Finley, Roy J. Martin, Michael J. Keenan, Frederic M. Enright, Frank L. Greenway Nov 2016

Using Caenorhabditis Elegans As A Model For Obesity Pharmacology Development, Jolene Zheng, Joseph R. Vasselli, Jason F. King, Michael L. King, Wenqian We, Zachary Fitzpatrick, William D. Johnson, John W. Finley, Roy J. Martin, Michael J. Keenan, Frederic M. Enright, Frank L. Greenway

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.

The Thr–His Connection On The Distal Heme Of Catalase-Related Hemoproteins: A Hallmark Of Reaction With Fatty Acid Hydroperoxides, Zahra Mashhadi, Marcia E. Newcomer, Alan R. Brash Nov 2016

The Thr–His Connection On The Distal Heme Of Catalase-Related Hemoproteins: A Hallmark Of Reaction With Fatty Acid Hydroperoxides, Zahra Mashhadi, Marcia E. Newcomer, Alan R. Brash

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 …

Twitter Predicts Citation Rates Of Ecological Research, Brandon K. Peoples, Stephen R. Midway, Dana Sackett, Abigail Lynch, Patrick B. Cooney

Faculty Publications

The relationship between traditional metrics of research impact (e.g., number of citations) and alternative metrics (altmetrics) such as Twitter activity are of great interest, but remain imprecisely quantified. We used generalized linear mixed modeling to estimate the relative effects of Twitter activity, journal impact factor, and time since publication on Web of Science citation rates of 1,599 primary research articles from 20 ecology journals published from 2012-2014. We found a strong positive relationship between Twitter activity (i.e., the number of unique tweets about an article) and number of citations. Twitter activity was a more important predictor of citation rates than …

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 …

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Peg3 (Paternally Expressed Gene 3) is an imprinted gene that encodes a zinc finger DNAbinding protein. Peg3 itself is localized in the middle of a KRAB-A (Kruppel-Associated Box) zinc finger gene cluster. The amino acid sequence encoded by its exon 7 also shows sequence similarity to that of KRAB-A, suggesting Peg3 as a KRAB-containing zinc finger gene. As predicted, the PEG3 …

Pancreatic Β-Cell Production Of Cxcr3 Ligands Precedes Diabetes Onset, Susan J. Burke, Michael D. Karlstad, Adrianna E. Eder, Kellie M. Regal, Danhong Lu, David H. Burk, J. Jason Collier

Faculty Publications

© 2016 International Union of Biochemistry and Molecular Biology Type 1 diabetes mellitus (T1DM) results from immune cell-mediated reductions in function and mass of the insulin-producing β-cells within the pancreatic islets. While the initial trigger(s) that initiates the autoimmune process is unknown, there is a leukocytic infiltration that precedes islet β-cell death and dysfunction. Herein, we demonstrate that genes encoding the chemokines CXCL9, 10, and 11 are primary response genes in pancreatic β-cells and are also elevated as part of the inflammatory response in mouse, rat, and human islets. We further established that STAT1 participates in the transcriptional control of …

© 2016 by the Ecological Society of America. Understanding the influence of environmental variability on population dynamics is a fundamental goal of ecology. Theory suggests that, for populations in variable environments, temporal correlations between demographic vital rates (e.g., growth, survival, reproduction) can increase (if positive) or decrease (if negative) the variability of year-to-year population growth. Because this variability generally decreases long-term population viability, vital rate correlations may importantly affect population dynamics in stochastic environments. Despite long-standing theoretical interest, it is unclear whether vital rate correlations are common in nature, whether their directions are predominantly negative or positive, and whether they …

The Negative Effects Of Pathogen-Infected Prey On Predators: A Meta-Analysis, Andrew J. Flick, Miguel A. Acevedo, Bret D. Elderd

Faculty Publications

© 2016 The Authors Intra-guild predation (IGP) – where a top predator (IGPred) consumes both a basal resource and a competitor for that resource (IGPrey) – has become a fundamental part of understanding species interactions and community dynamics. IGP communities composed of intraguild predators and prey have been well studied; however, we know less about IGP communities composed of predators, pathogens, and resources. Resource quality plays an important role in community dynamics and may influence IGP dynamics as well. We conducted a meta-analysis on predator–pathogen–resource communities to determine whether resource quality mediated by the pathogen affected predator life-history traits and …

The Impact Of A Large-Scale Climate Event On Antarctic Ecosystem Processes, Andrew G. Fountain, Grace Saba, Byron Adams, Peter Doran, William Fraser, Michael Gooseff, Maciej Obryk, John C. Priscu, Sharon Stammerjohn, Ross A. Virginia

Faculty Publications

© 2016 The Author(s) 2016. Extreme climate and weather events, such as a drought, hurricanes, or ice storms, can strongly imprint ecosystem processing and may alter ecosystem structure. Ecosystems in extreme environments are particularly vulnerable because of their adaptation to severe limitations in energy, water, or nutrients. The vulnerability can be expressed as a relatively long-lasting ecosystem response to a small or brief change in environmental conditions. Such an event occurred in Antarctica and affected two vastly different ecosystems: a marine-dominated coastal system and a terrestrial polar desert. Both sites experienced winds that warmed air temperatures above the 0°C threshold, …

Cryopreservation Of Lipid Bilayers By Lea Proteins From Artemia Franciscana And Trehalose, Daniel S. Moore, Steven C. Hand

Faculty Publications

© 2016 Elsevier Inc. The capacity of Late Embryogenesis Abundant (LEA) proteins and trehalose to protect liposomes against freezing-induced damage was examined by measuring the leakage of 5(6)-carboxyfluorescein (CF). Liposomes were prepared to simulate the lipid compositions of the inner leaflet of the plasma membrane, outer mitochondrial membrane (OMM), and inner mitochondrial membrane (IMM). Two recombinant LEA proteins belonging to Group 3 (AfrLEA2 and AfrLEA3m) were expressed and purified from embryos of Artemia franciscana. Only OMM-like liposomes were significantly protected by AfrLEA2 and AfrLEA3m against freeze-thaw damage; at the highest protein:lipid mass ratio tested, leakage of CF was 56.3% of …

Do Movement Behaviors Identify Reproductive Habitat Sampling For Wild Turkeys?, Mason D. Conley, Nathan A. Yeldell, Michael J. Chamberlain, Bret A. Collier

Faculty Publications

Selection of habitats has regularly been suggested to influence species demography at both local and broad scales. The expectation is that selection behaviors have positive benefits via greater fitness or increased survival. The current paradigm of habitat selection theory suggests a hierarchical process, where an individual first selects where they choose to live (e.g., range) and then searches and selects locations within this range meeting life history needs. Using high-frequency GPS data collected from reproductively active Rio Grande (n = 21) and Eastern (n = 23) wild turkeys, we evaluated a long-standing theory for ground-nesting galliformes, in that movements during …

In cattle, maternal recognition of pregnancy occurs on Day 16 via secretion of interferon tau (IFNT) by the conceptus. The endometrium can distinguish between embryos with different developmental competencies. In eutherian mammals, X-chromosome inactivation (XCI) is required to ensure an equal transcriptional level of most X-linked genes for both male and female embryos in adult tissues, but this process is markedly different in cattle than mice. We examined how sexual dimorphism affected conceptus transcript abundance and amino acid composition as well as the endometrial transcriptome during the peri-implantation period of pregnancy. Of the 5132 genes that were differentially expressed on …
