An Adenovirus-Derived Protein: A Novel Candidate For Anti-Diabetic Drug Development, Vijay Hegde, Ha Na Na, Olga Dubuisson, Susan J. Burke, J. Jason Collier, David Burk, Tamra Mendoza, Nikhil V. Dhurandhar

Faculty Publications

© 2015 Elsevier B.V. and Société Française de Biochimie et Biologie Moléculaire (SFBBM). Aims Exposure to human adenovirus Ad36 is causatively and correlatively linked with better glycemic control in animals and humans, respectively. Although the anti-hyperglycemic property of Ad36 may offer some therapeutic potential, it is impractical to use an infectious agent for therapeutic benefit. Cell-based studies identified that Ad36 enhances cellular glucose disposal via its E4orf1 protein. Ability to improve glycemic control in vivo is a critical prerequisite for further investigating the therapeutic potential of E4orf1. Therefore, the aim of this study was to determine the ability of E4orf1 …

To increase our understanding of the genetic basis of adiposity and its links to cardiometabolic disease risk, we conducted a genome-wide association meta-analysis of body fat percentage (BF%) in up to 100,716 individuals. Twelve loci reached genome-wide significance (Po5108), of which eight were previously associated with increased overall adiposity (BMI, BF%) and four (in or near COBLL1/GRB14, IGF2BP1, PLA2G6, CRTC1) were novel associations with BF%. Seven loci showed a larger effect on BF% than on BMI, suggestive of a primary association with adiposity, while five loci showed larger effects on BMI than on BF%, suggesting association with both fat and …

Feedstock Analysis Sensitivity For Estimating Ethanol Production Potential In Switchgrass And Energycane Biomass, Kun Jun Han, Younghwan Moon, Donal F. Day, William D. Pitman Feb 2016

Feedstock Analysis Sensitivity For Estimating Ethanol Production Potential In Switchgrass And Energycane Biomass, Kun Jun Han, Younghwan Moon, Donal F. Day, William D. Pitman

Faculty Publications

Efficient ethanol production from lignocellulosic biomass requires highly degradable feedstock; therefore, there is a similarity between forage crop production for ruminant animals and ethanol production from lignocellulosic biomass. Feed value analysis techniques may be used to estimate lignocellulosic biomass quality. Because lignin and its derivatives in cell walls are major compounds interrupting biomass degradation, fiber analysis and in vitro incubation tests were conducted with switchgrass (Panicum virgatum) and energycane (Saccharum spp.) biomass collected at 100 and 120g lignin (acid detergent lignin) kg-1 DM (dry matter). Mean NDF (neutral detergent fiber) in switchgrass was consistently greater than that of energy cane …

Lentic And Lotic Habitats As Templets For Fungal Communities: Traits, Adaptations, And Their Significance To Litter Decomposition Within Freshwater Ecosystems, Kevin A. Kuehn Feb 2016

Lentic And Lotic Habitats As Templets For Fungal Communities: Traits, Adaptations, And Their Significance To Litter Decomposition Within Freshwater Ecosystems, Kevin A. Kuehn

Faculty Publications

Decomposition of plant matter is a key ecosystem process and considerable research has examined plant litter decay processes in freshwater habitats. Fungi are common inhabitants of the decomposer microbial community and representatives of all major fungal phyla have been identified within freshwater systems. Development and application of quantitative methods over the last several decades have firmly established that fungi are central players in the decomposition of plant litter in freshwaters and are important mediators of energy and nutrient transfer to higher trophic levels. Despite the critical roles that fungi play in carbon and nutrient cycling in freshwater ecosystems, there are …

Reduced glomerular filtration rate defines chronic kidney disease and is associated with cardiovascular and all-cause mortality. We conducted a meta-analysis of genome-wide association studies for estimated glomerular filtration rate (eGFR), combining data across 133,413 individuals with replication in up to 42,166 individuals. We identify 24 new and confirm 29 previously identified loci. Of these 53 loci, 19 associate with eGFR among individuals with diabetes. Using bioinformatics, we show that identified genes at eGFR loci are enriched for expression in kidney tissues and in pathways relevant for kidney development and transmembrane transporter activity, kidney structure, and regulation of glucose metabolism.

The Modulation Of Adiponectin By Stat5-Activating Hormones, Ursula A. White, Joel Maier, Peng Zhao, Allison J. Richard, Jacqueline M. Stephens Jan 2016

The Modulation Of Adiponectin By Stat5-Activating Hormones, Ursula A. White, Joel Maier, Peng Zhao, Allison J. Richard, Jacqueline M. Stephens

Faculty Publications

© 2016 the American Physiological Society. Adiponectin is a hormone secreted from adipocytes that plays an important role in insulin sensitivity and protects against metabolic syndrome. Growth hormone (GH) and prolactin (PRL) are potent STAT5 activators that regulate the expression of several genes in adipocytes. Studies have shown that the secretion of adiponectin from adipose tissue is decreased by treatment with PRL and GH. In this study, we demonstrate that 3T3-L1 adipocytes treated with GH or PRL exhibit a reduction in adiponectin protein levels. Furthermore, we identified three putative STAT5 binding sites in the murine adiponectin promoter and show that …

Impact Of The 2010 Deepwater Horizon Oil Spill On Population Size And Genetic Structure Of Horse Flies In Louisiana Marshes, Claudia Husseneder, Jennifer R. Donaldson, Lane D. Foil Jan 2016

Impact Of The 2010 Deepwater Horizon Oil Spill On Population Size And Genetic Structure Of Horse Flies In Louisiana Marshes, Claudia Husseneder, Jennifer R. Donaldson, Lane D. Foil

Faculty Publications

The greenhead horse fly, Tabanus nigrovittatus Macquart, is frequently found in coastal marshes of the Eastern United States. The greenhead horse fly larvae are top predators in the marsh and thus vulnerable to changes in the environment, and the adults potentially are attracted to polarized surfaces like oil. Therefore, horse fly populations could serve as bioindicators of marsh health and toxic effects of oil intrusion. In this study, we describe the impact of the April 2010 Deep Water Horizon oil spill in the Gulf of Mexico on tabanid population abundance and genetics as well as mating structure. Horse fly populations …

Faculty Publications

© 2016 Nature America, Inc. Rationale: Caveolin-1 (Cav-1) negatively regulates endothelial nitric oxide (NO) synthase-derived NO production, and this has been mapped to several residues on Cav-1, including F92. Herein, we reasoned that endothelial expression of an F92ACav-1 transgene would let us decipher the mechanisms and relationships between caveolae structure and intracellular signaling. Objective: This study was designed to separate caveolae formation from its downstream signaling effects. Methods and Results: An endothelial-specific doxycycline-regulated mouse model for the expression of Cav-1-F92A was developed. Blood pressure by telemetry and nitric oxide bioavailability by electron paramagnetic resonance and phosphorylation of vasodilator-stimulated phosphoprotein were …

Molar Tooth Carbonates And Benthic Methane Fluxes In Proterozoic Oceans, Bing Shen, Lin Dong, Shuhai Xiao, Xianguo Lang, Kangjun Huang, Yongbo Peng, Chuanming Zhou, Shan Ke, Pengju Liu

Faculty Publications

Molar tooth structures are ptygmatically folded and microspar-filled structures common in early- and mid-Proterozoic (â 1/42,500-750 million years ago, Ma) subtidal successions, but extremely rare in rocks Here, on the basis of Mg and S isotopes, we show that molar tooth structures may have formed within sediments where microbial sulphate reduction and methanogenesis converged. The convergence was driven by the abundant production of methyl sulphides (dimethyl sulphide and methanethiol) in euxinic or H 2 S-rich seawaters that were widespread in Proterozoic continental margins. In this convergence zone, methyl sulphides served as a non-competitive substrate supporting methane generation and methanethiol inhibited …

Road-Edge Effects On Herpetofauna In A Lowland Amazonian Rainforest, Ross J. Maynard, Nathalie C. Aall, Daniel Saenz, Paul S. Hamilton, Matthew Kwiatkowski

Faculty Publications

The impact of roads on the flora and fauna of Neotropical rainforest is perhaps the single biggest driver of habitat modification and population declines in these ecosystems. We investigated the road-edge effect of a low-use dirt road on amphibian and reptile abundance, diversity, and composition within adjacent lowland Amazonian rainforest at San José de Payamino, Ecuador. The road has been closed to vehicle traffic since its construction in 2010. Thus, effects from vehicle mortality, vehicle-related pollution, and road noise were not confounding factors. Herpetofauna were surveyed using both visual encounter surveys and drift fences with pitfall and funnel traps at …

Energy is a crosscutting concept in science and features prominently in national science education documents. In the Next Generation Science Standards, the primary conceptual learning goal is for learners to conserve energy as they track the transfers and transformations of energy within, into, or out of the system of interest in complex physical processes. As part of tracking energy transfers among objects, learners should (i) distinguish energy from matter, including recognizing that energy flow does not uniformly align with the movement of matter, and should (ii) identify specific mechanisms by which energy is transferred among objects, such as mechanical work …

Characterization Of The Three Zebrafish Orthologs Of The Mitochondrial Gtpase Miro/Rhot, Brittany M. Hollister, Kelsey A. Oonk, Douglas C. Weiser, Susan Walsh

Faculty Publications

Mitochondria exhibit dynamic locomotion and spatial rearrangement. This movement is necessary for a cell to maintain basic metabolic functions, and disruption of motility often results in cell death. Miro is a mitochondrial outer membrane Rho GTPase essential for mitochondrial movement and distribution in diverse systems, including yeast, animals, and plants. We sought to study the previously uncharacterized Miro protein family in zebrafish. We confirmed that, like human Miro, the zebrafish Miro proteins (Rhot1a, Rhot1b, and Rhot2) localize to mitochondria in mammalian tissue culture cells by both biochemical fractionation and immunofluorescent colocalization. In addition, using whole mount in situ hybridization, we …

Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition and abundance has not been fully elucidated. Genomic DNA was extracted from settled dust and personal inhalable dust collected while performing litter sampling or mortality collection tasks. DNA libraries were sequenced using a paired-end sequencing-by-synthesis approach on an Illumina HiSeq 2500. Sequencing data showed that poultry dust is predominantly composed of bacteria (64–67%) with a small quantity of avian, human and feed DNA (< 2% of total reads). Staphylococcus sp. AL1, Salinicoccus carnicancri and Lactobacillus crispatus were the most abundant bacterial species in personal exposure samples of inhalable dust. Settled dust had a moderate relative abundance of these species as well as Staphylococcus lentus and Lactobacillus salivarius. There was a statistical difference between the microbial composition of aerosolized and settled dust. Unlike settled dust composition, aerosolized dust composition had little variance between samples. These data provide an extensive analysis of the microbial composition and relative abundance in personal inhalable poultry dust and settled poultry dust.

Habitat Use And Avoidance By Foraging Red-Cockaded Woodpeckers In East Texas, John N. Macey, Brent Burt, Daniel Saenz, Richard N. Conner

Faculty Publications

Picoides borealis (Red-cockaded Woodpecker) is an endangered bird endemic to the Pinus (pine) ecosystems of the southeastern US. Mature pine savannahs with a minimal midstory and lush herbaceous groundcover represent high-quality habitat. This study examines the foraging-habitat patterns of Red-cockaded Woodpeckers in East Texas. We present a logistic regression model that best differentiates between foraged and non-foraged habitat. Increases in hardwood-midstory basal area have the greatest negative impact on the probability of Red-cockaded Woodpeckers selecting a habitat patch for foraging. Five additional variables negatively impact foraging probability: shrub height, diameter at breast height (DBH) of pine midstory, canopy closure, density …

Blackfish-Ing For Buzz: The Rhetoric Of The Real In Theme Parks And Documentary, Steven W. Schoen

Faculty Publications

In 2014, a year of record tourism in the state of Florida, SeaWorld saw a drop of one million visitors to its theme park in Orlando. The decline followed Gabriela Cowperthwaite’s 2013 documentary film Blackfish, which presented the circumstances of orcas, or “killer whales,” held in captivity at parks like SeaWorld as cruel to the animals and dangerous to their trainers. In 2016, SeaWorld announced it will stop breeding orcas, and phase out its orca theatrical shows by 2019, a move widely attributed in the press to the impact of Cowperthwaite’s film.

Is The Clean Air Act Unconstitutional? Coercion, Cooperative Federalism And Conditional Spending After Nfib V. Seblius, Jonathan Adler, Nathaniel Stewart

Faculty Publications

The Clean Air Act (CAA) is a persistent source of federal-state conflict. Like many federal environmental laws, the CAA relies upon the cooperation of state environmental agencies for its execution and enforcement. To induce such cooperation, the CAA authorizes, even requires, the imposition of sanctions on noncooperating states, including the loss of federal highway funds. NFIB v. Sebelius, however, casts doubt on the constitutionality of the CAA’s sanction regime. Specifically, NFIB enforced limits on the use of conditional spending to induce state cooperation with a federal program and held that Congress may not use conditional spending to “coerce” state …

Endocidal Regulation Of Secondary Metabolites In The Producing Organisms, Shiyou Li, Ping Wang, Wei Yuan, Zushang Su, Steven H. Bullard Jan 2016

Endocidal Regulation Of Secondary Metabolites In The Producing Organisms, Shiyou Li, Ping Wang, Wei Yuan, Zushang Su, Steven H. Bullard

Faculty Publications

Secondary metabolites are defined as organic compounds that are not directly involved in the normal growth, development, and reproduction of an organism. They are widely believed to be responsible for interactions between the producing organism and its environment, with the producer avoiding their toxicities. In our experiments, however, none of the randomly selected 44 species representing different groups of plants and insects can avoid autotoxicity by its endogenous metabolites once made available. We coined the term endocides (endogenous biocides) to describe such metabolites that can poison or inhibit the parent via induced biosynthesis or external applications. Dosage-dependent endocides can selectively …
